2) History
LuminArx Capital Management LP was founded in January 2023 by co-founders Gideon Berger and Min Htoo, both former senior executives at Blackstone Alternative Asset Management (BAAM). The firm was established as a global alternative investment manager focused on Special Situations investing, representing a natural evolution from the founders’ extensive experience in the hedge fund solutions space at Blackstone.
Prior to launching LuminArx, both founders held senior leadership positions at BAAM, where Berger served as Senior Managing Director and Co-Chief Investment Officer, chairing BAAM’s Investment Committee and serving on its Management Committee. During his tenure at BAAM, Berger oversaw significant growth as client assets expanded from approximately $1 billion to $80 billion. Min Htoo similarly served as Senior Managing Director and Co-Chief Investment Officer at BAAM, where he was a member of both the Investment Committee and Management Committee.
LuminArx registered with the Securities and Exchange Commission as an investment adviser with registration effective November 6, 2023. The firm quickly gained market attention, with Bloomberg reporting on the launch in August 2023, noting the founders’ plans to start a $1 billion fund and expectations for the firm to join the “billion-dollar hedge fund club.”
The firm demonstrated rapid growth and institutional recognition through significant strategic partnerships. In January 2024, LuminArx announced the launch of Cinergy, a strategic private lending vehicle in collaboration with Citigroup, backed by over $2 billion in committed capital from LuminArx and its global institutional partners. This partnership represented a major milestone in the firm’s evolution, providing access to private credit opportunities sourced by Citi alongside the Wall Street firm’s financing capabilities.
Throughout 2024 and 2025, LuminArx continued expanding its investment activities across multiple sectors. Notable transactions included aircraft acquisitions with Phoenix Aviation Capital and AIP Capital in March 2025, demonstrating the firm’s expansion into asset-backed financing. The firm also completed significant investments in technology companies, including a preferred equity investment in Axonic Insurance for $210 million alongside Deutsche Bank in October 2025, and participated in Vultr’s financing at a $3.5 billion valuation in December 2024.
LuminArx successfully sponsored and closed its first asset-backed securities transaction in 2025, marking a major milestone for the platform with the UPX HI 2025-1 issuance backed by unsecured, fixed-rate home improvement loans. The firm’s growth trajectory has been supported by strategic hires of experienced professionals from leading financial institutions, building a team with over 100 years of combined investment experience within the asset management industry.

4) Ownership
LuminArx Capital Management LP operates as a private limited partnership structured under Delaware law, with ownership concentrated between its two co-founders. According to SEC filings, the firm is owned by Gideon Berger and Min Htoo through a sophisticated ownership structure involving multiple entity layers.
The ownership architecture consists of LuminArx Capital Management Holdings LP as the primary limited partner holding 75% or more of the firm, with LuminArx Capital Management GP LLC serving as the general partner with less than 5% ownership. Behind these entities, the ultimate control rests with the co-founders through their respective ownership vehicles: the Gideon Berger Trust holds more than 25% but less than 50% as a limited partner, while Min Zaw Htoo similarly holds more than 25% but less than 50% as a limited partner.
Since the firm’s inception in January 2023, there have been no significant changes in the core ownership structure between the founding partners. The firm has maintained its private ownership status throughout its operating history, with no external private equity involvement or third-party strategic investors reported in available filings.
LuminArx has demonstrated rapid capital growth through institutional partnerships rather than external ownership changes. The firm’s most significant strategic alliance involves a collaboration with Citigroup through the launch of Cinergy, a private lending vehicle backed by over $2 billion in committed capital from LuminArx and its global institutional partners. This arrangement represents a strategic financing partnership rather than an ownership stake, with Citi’s Spread Products franchise providing leverage solutions to expand Cinergy’s investment capacity.
The firm operates through multiple subsidiary entities to support its various fund structures and investment activities. These include LuminArx Capital Fund GP LP and LuminArx Capital GP LLC, which serve as general partners for the firm’s various investment vehicles. Additional affiliates such as LuminArx Capital Fund Opt-In GP LP support specific fund structures within the firm’s master-feeder arrangements.
As a private alternative investment manager, LuminArx has not pursued public listing or external capital raising beyond institutional investor commitments to its investment funds. The firm’s growth strategy has focused on organic expansion and strategic partnerships rather than dilutive external financing, maintaining the concentrated ownership structure established at founding.
The partnership structure provides both co-founders with significant control over the firm’s strategic direction while allowing for the sophisticated fund structures necessary for institutional alternative investment management. This ownership model is typical among emerging alternative investment managers seeking to maintain founder control while accessing institutional capital markets.
5) Financial Position
As of December 31, 2024, LuminArx Capital Management LP manages approximately $3.2 billion in regulatory assets under management, with $2.6 billion on a discretionary basis and $620 million on a non-discretionary basis. This represents remarkable growth for a firm founded in January 2023, demonstrating rapid institutional investor adoption and confidence in the firm’s investment approach.
The firm’s financial position has been strengthened through significant institutional partnerships, most notably the collaboration with Citigroup through the launch of Cinergy, a private lending vehicle backed by over $2 billion in committed capital from LuminArx and its global institutional partners. This partnership provides substantial capital availability and access to financing solutions through Citi’s Spread Products franchise, enhancing the firm’s ability to execute larger transactions and expand its investment capacity.
LuminArx operates with a lean organizational structure of 24 employees, with 67% serving in investment roles, indicating efficient resource allocation focused on core investment activities. The firm’s minimum investment requirements are typically set at $5 million for institutional investors, reflecting its focus on sophisticated institutional capital rather than retail investors.
The firm has demonstrated strong capital deployment capabilities across multiple investment strategies and sectors. Notable transactions include leading Vultr’s $333 million growth financing at a $3.5 billion valuation, participating in Upgrade’s $165 million Series G equity round, and completing a $210 million preferred equity investment in Axonic Insurance alongside Deutsche Bank. These transactions illustrate the firm’s ability to commit significant capital to individual investments while maintaining portfolio diversification.
Revenue generation is primarily derived from management fees and carried interest across multiple fund structures, including private equity funds, hedge funds, direct lending funds, and co-investment vehicles. The firm operates through sophisticated master-feeder structures that allow for tax-efficient fund management while accommodating diverse institutional investor requirements.
LuminArx has successfully expanded into asset-backed securities markets, sponsoring and closing its first ABS transaction with the UPX HI 2025-1 issuance backed by home improvement loans. This demonstrates the firm’s ability to develop new revenue streams and capital markets capabilities beyond traditional private investment activities.
The firm’s financial stability is supported by its diversified investment approach across multiple asset classes, including special situations investing, private credit, asset-backed financing, and growth equity investments. This diversification helps mitigate concentration risks while providing multiple sources of fee income and investment returns.
6) Market Position
LuminArx Capital Management LP has rapidly established itself as a significant player in the alternative investment management industry, particularly within the special situations and private credit markets. Since its founding in January 2023, the firm has achieved remarkable market recognition, receiving an Honourable Mention as “Newcomer of the Year” in the SCI Capital Relief Trades Awards covering the period from July 2023 to June 2024.
The firm’s market position is distinguished by its strategic focus on Special Situations investing, providing innovative and flexible capital solutions with an emphasis on consistent returns across market environments. This positioning differentiates LuminArx from traditional private equity or hedge fund managers by targeting opportunities where compelling returns can be generated through creativity and flexibility rather than conventional investment approaches.
LuminArx has established a competitive advantage through its institutional partnerships, most notably the strategic collaboration with Citigroup for the launch of Cinergy. This partnership provides the firm with access to private credit opportunities sourced by Citi’s extensive global client network while utilizing Citi’s financing capabilities through its leading Spread Products franchise. Such relationships are rare in the industry and provide significant competitive moats for deal sourcing and execution.
The firm competes effectively in multiple market segments, including private credit, asset-backed securities, technology growth investments, and asset-backed financing. Recent investments demonstrate the firm’s ability to compete for high-quality opportunities, including leading Vultr’s financing at a $3.5 billion valuation alongside AMD Ventures and participating in significant transactions with companies like Upgrade and Axonic Insurance.
LuminArx has successfully positioned itself in the growing private credit market, which has experienced significant expansion as institutional investors seek alternatives to traditional fixed income investments. The firm’s ability to provide bespoke financing solutions across the capital structure allows it to capture opportunities in this expanding market while serving diverse institutional investor needs.
The firm’s market credibility has been enhanced by the reputation and track record of its leadership team, particularly co-founders Gideon Berger and Min Htoo, who previously served as Co-Chief Investment Officers at Blackstone Alternative Asset Management. Their experience overseeing growth from approximately $1 billion to $80 billion in client assets at BAAM provides significant credibility with institutional investors and counterparties.
LuminArx has demonstrated strong execution capabilities in complex transactions, including successful completion of its first asset-backed securities transaction and expansion into aviation finance through aircraft acquisitions. This execution track record helps establish the firm’s reputation as a reliable capital provider capable of handling sophisticated transaction structures.
The firm’s market position benefits from its focus on institutional-grade compliance and governance standards as an SEC-registered investment adviser. This regulatory status provides institutional investors with confidence in the firm’s operational standards and differentiates it from less regulated alternative investment managers.
7) Legal Claims and Actions
Based on comprehensive analysis of available public records and regulatory filings, LuminArx Capital Management LP has maintained a clean regulatory and legal record since its founding in January 2023. The firm has not been subject to any SEC enforcement actions, regulatory sanctions, or material litigation during its operating history.
As of its most recent Form ADV filing in May 2025, LuminArx Capital Management LP reports no disclosure events across all regulatory categories, including criminal proceedings, civil judicial proceedings, administrative proceedings before the SEC, self-regulatory organization proceedings, or bankruptcy filings. The firm’s clean compliance record reflects its recent establishment and the comprehensive compliance infrastructure implemented at inception.
Justin Neuman, the firm’s Legal Counsel and Chief Compliance Officer, joined from D1 Capital Partners LP where he managed legal and compliance infrastructure. Prior to D1, Neuman served as an Associate at Paul, Weiss, Rifkind, Wharton & Garrison LLP in their Private Funds Group, bringing significant regulatory expertise to LuminArx’s compliance framework. His background includes representation of hedge funds, private equity funds, and fund-of-funds in formation and ongoing compliance matters.
The firm’s regulatory approach benefits from the extensive experience of its co-founders, who previously served as senior executives at Blackstone Alternative Asset Management, where they gained deep familiarity with institutional-grade compliance requirements and regulatory oversight. This background has informed LuminArx’s development of comprehensive policies and procedures designed to meet SEC investment adviser obligations.
LuminArx Capital Management LP is registered as an investment adviser with the SEC, with registration effective November 6, 2023. The firm’s Form ADV filings indicate compliance with all applicable recordkeeping, disclosure, and reporting requirements under the Investment Advisers Act of 1940. The firm operates exclusively with pooled investment vehicles as clients and maintains appropriate custody arrangements through qualified custodians.
The absence of regulatory enforcement actions or material litigation reflects both the firm’s recent establishment and its implementation of robust compliance systems from inception. Given the firm’s founding by experienced alternative investment professionals and its institutional focus, LuminArx has prioritized regulatory compliance as a core operational requirement.
As a relatively new entity in the alternative investment management space, LuminArx Capital Management LP has not accumulated the type of historical regulatory issues that can affect more established firms with longer operating histories. The firm’s clean record provides a strong foundation for its continued growth and institutional investor relationships.
8) Recent Media
Media coverage of LuminArx Capital Management since its inception has been predominantly positive, focusing on its high-profile launch, rapid expansion through strategic partnerships, and significant investment activities across various sectors. In August 2023, outlets including Bloomberg reported on the firm’s formation by former Blackstone Alternative Asset Management (BAAM) co-Chief Investment Officers, Gideon Berger and Min Htoo. The reports highlighted expectations for the firm to launch with over $1 billion in capital, positioning it as a major new entrant in the special situations and alternative investment space.
In January 2024, LuminArx announced a major strategic partnership with Citigroup to launch Cinergy, a private lending vehicle. The launch, covered by Investment News and other financial news outlets, detailed that LuminArx and its institutional partners committed over $2 billion in capital to the platform, which will offer asset-backed and corporate credit solutions to Citi’s global client base. Mitali Sohoni, Citi’s Head of Asset-Backed Financing, stated that Cinergy would “enhance our ability to meet the capital needs of our clients,” while LuminArx CEO Gideon Berger described the vehicle as “unique in the market” for investors looking to capitalize on the growth of private credit.
Throughout 2024 and 2025, media announcements highlighted the firm’s investment activity in technology and asset-backed finance. In December 2024, LuminArx co-led a $333 million growth financing round for cloud infrastructure provider Vultr, alongside AMD Ventures, at a $3.5 billion valuation. Tanisha Keshava Bellur, a Partner at LuminArx, noted that Vultr “distinguishes itself through exceptional leadership, outstanding execution, and a proven track record.” In March 2025, the firm jointly acquired a portfolio of three Airbus A330-300 aircraft with Phoenix Aviation Capital and AIP Capital, marking an expansion into aviation finance. LuminArx Partner Sanjeev Mordani stated the firm was “delighted to have partnered with AIP Capital to complete the financing.”
In 2024, LuminArx received an Honourable Mention as “Newcomer of the Year” in the SCI Capital Relief Trades Awards, which covered the period from July 2023 to June 2024. The firm’s progress in asset-backed securities was further noted in August 2025, when it announced the sponsorship and closing of its first ABS transaction, UPX HI 2025-1, which was backed by a pool of home improvement loans originated by Upgrade, Inc.
In October 2025, press releases confirmed LuminArx led a $210 million preferred equity investment in global annuity and insurance platform Axonic Insurance, with participation from Deutsche Bank. LuminArx partner Sanjeev Mordani stated, “We are excited to support Axonic Insurance in this next phase of growth.” The same month, the firm participated in fintech company Upgrade, Inc.’s $165 million Series G equity round, building on a prior relationship that included loan purchases and leading Upgrade’s first home improvement loan securitization. A statement from LuminArx noted it was “excited to deepen our collaboration” with the Upgrade team.
A review of media coverage reveals no significant adverse reports concerning regulatory or legal actions, ESG controversies, client terminations, or cybersecurity incidents involving LuminArx Capital Management or its key executives since its founding.
9) Strengths
Experienced Leadership Team with Track Record at Leading Institutions
LuminArx Capital Management LP benefits from an exceptional leadership team with extensive experience at top-tier alternative investment management firms. Co-founders Gideon Berger and Min Htoo previously served as Senior Managing Directors and Co-Chief Investment Officers at Blackstone Alternative Asset Management (BAAM), where they oversaw significant growth as client assets expanded from approximately $1 billion to $80 billion during Berger’s tenure. The firm’s leadership team collectively possesses over 100 years of combined investment experience within the asset management industry, providing deep expertise in structuring and risk management across market cycles.
Strategic Institutional Partnerships and Market Access

This partnership provides LuminArx with access to private credit opportunities sourced by Citi’s extensive global client network while utilizing Citi’s distinct financing capabilities through its leading Spread Products franchise. These relationships enable the firm to access unique deal flow and leverage institutional-grade infrastructure.
Rapid Asset Growth and Market Recognition
Since its founding in January 2023, LuminArx has achieved remarkable growth, reaching approximately $3.2 billion in regulatory assets under management as of December 2024. The firm’s rapid scaling demonstrates strong institutional investor confidence and market validation of its investment approach. LuminArx received an Honourable Mention as “Newcomer of the Year” in the SCI Capital Relief Trades Awards covering the period from July 2023 to June 2024, highlighting its quick establishment as a recognized player in the structured credit markets.
Diversified Investment Capabilities Across Asset Classes
LuminArx operates with a sophisticated investment approach spanning multiple asset classes and strategies, including asset-backed credit, corporate debt, direct lending, co-investment vehicles, and private equity funds. The firm’s ability to provide flexible, bespoke financing solutions across the capital structure allows it to capitalize on various market opportunities while serving diverse institutional investor needs. This diversification is evidenced by investments ranging from technology companies like Vultr at a $3.5 billion valuation to aircraft acquisitions and asset-backed securities transactions.
Proven Execution in Complex Transactions
The firm has demonstrated strong execution capabilities across sophisticated transaction types, including successful completion of its first asset-backed securities transaction with the UPX HI 2025-1 issuance backed by home improvement loans. LuminArx’s investment activities span multiple sectors and geographies, with notable transactions including leading a $333 million growth financing for cloud infrastructure provider Vultr, participating in Upgrade’s $165 million Series G round, and completing a $210 million preferred equity investment in Axonic Insurance alongside Deutsche Bank.
SEC-Registered Investment Adviser with Institutional Focus
As an SEC-registered investment adviser with registration effective November 6, 2023, LuminArx operates under comprehensive regulatory oversight and compliance requirements. The firm maintains a clean regulatory record with no disclosure events across all regulatory categories, reflecting robust compliance infrastructure implemented from inception. This regulatory status provides institutional investors with confidence in the firm’s operational standards and governance practices.
Specialized Focus on Special Situations Investing
LuminArx’s specialized focus on Special Situations investing with emphasis on consistent returns across market environments while mitigating downside risks differentiates the firm in the alternative investment landscape. The firm targets situations where compelling returns can be generated through creativity and flexibility, leveraging a diverse ecosystem of relationships across banks, corporations, governments, and insurance companies. This approach allows the firm to identify unique investment opportunities that may not be accessible to traditional investment managers.
Strong Talent Acquisition from Industry Leaders
The firm has successfully recruited experienced professionals from leading financial institutions, building a team of 24 employees with 67% serving in investment roles. Key team members bring expertise from institutions including Blackstone, Citigroup, Deutsche Bank, HPS Investment Partners, and other prominent firms, providing deep industry relationships and specialized knowledge across multiple investment strategies and sectors.
10) Potential Risk Areas for Further Diligence
Limited Operating History and Performance Track Record
LuminArx Capital Management LP’s limited operating history since January 2023 presents significant due diligence challenges for institutional investors. With less than three years of operational experience, the firm lacks the extended performance data typically required for comprehensive risk assessment. The absence of full market cycle performance data particularly impacts evaluation of the firm’s investment strategies during periods of economic stress, market volatility, or credit cycle downturns. This limited track record makes it difficult to assess the sustainability of investment returns, the effectiveness of risk management protocols during adverse conditions, and the stability of client relationships over extended periods.
Key Person Risk and Leadership Concentration
The firm’s substantial concentration of investment decision-making authority in co-founders Gideon Berger and Min Htoo creates significant key person dependency risk. As Co-Founder and Chief Investment Officer, Min Htoo leads the firm’s investment committee and manages core investment activities, while Berger serves as CEO with ultimate operational oversight. The departure of either co-founder could materially impact the firm’s ability to execute its investment strategy, maintain institutional relationships, and preserve continuity of operations. Given the firm’s recent establishment and rapid growth to approximately $3.2 billion in assets under management, succession planning and business continuity arrangements warrant detailed examination.
Rapid Asset Growth and Operational Scalability Concerns
LuminArx has experienced extraordinary growth from inception to approximately $3.2 billion in regulatory assets under management within approximately two years of operations. This rapid expansion raises questions about the firm’s ability to maintain investment discipline, preserve investment performance, and scale operational infrastructure appropriately. The speed of growth may strain internal systems, compliance frameworks, and risk management capabilities, particularly given the firm’s relatively small team of 24 employees. Institutional investors should assess whether the firm’s operational infrastructure, technology systems, and personnel resources can support continued growth without compromising investment quality or regulatory compliance.
Complex Fund Structure and Liquidity Management Risks
The firm operates multiple investment vehicles through sophisticated master-feeder structures, including private equity funds, hedge funds, direct lending funds, and co-investment vehicles with varying liquidity profiles. This complex fund architecture creates potential liquidity mismatches, particularly given the firm’s focus on illiquid special situations investing and private credit markets. The coordination of multiple fund structures with different investor bases, redemption terms, and investment mandates presents operational complexity and potential conflicts of interest that require ongoing monitoring. Additionally, the firm’s concentration in alternative investments may create challenges during periods of market stress when traditional exit strategies become constrained.
Counterparty and Partnership Dependency Risks
LuminArx’s strategic partnership with Citigroup through the Cinergy vehicle, while providing access to deal flow and leverage capabilities, creates significant counterparty dependency risks. The firm’s ability to execute its investment strategy relies heavily on continued access to private credit opportunities sourced through Citi’s global client network and the availability of financing solutions through Citi’s Spread Products franchise. Any deterioration in this relationship, changes in Citi’s strategic priorities, or regulatory restrictions affecting banking partnerships could materially impact LuminArx’s investment capacity and competitive positioning. The firm’s success is also dependent on relationships with other institutional partners who provide capital commitments exceeding $2 billion for the Cinergy platform.
Regulatory and Compliance Infrastructure Risk
As a recently established SEC-registered investment adviser, LuminArx faces ongoing challenges in maintaining comprehensive compliance with evolving regulatory requirements across multiple jurisdictions and investment strategies. The firm’s expansion into asset-backed securities, structured credit transactions, and cross-border investments subjects it to complex regulatory frameworks that require specialized expertise and robust compliance systems. Given the firm’s rapid growth and relatively small compliance team led by Chief Compliance Officer Justin Neuman, there may be risks associated with maintaining adequate regulatory oversight across all business lines and investment vehicles.
Market Concentration and Strategy Drift Risks
LuminArx’s focus on special situations investing across multiple asset classes creates exposure to concentration risks in specific market segments or investment themes. The firm’s investment activities span private credit, asset-backed securities, technology growth investments, and aviation finance, raising questions about strategy coherence and risk concentration. The breadth of investment mandates may indicate potential strategy drift or insufficient focus on core competencies, particularly as the firm seeks to deploy growing amounts of institutional capital across diverse opportunity sets.
Technology and Cybersecurity Risks
As a data-intensive alternative investment manager handling sensitive institutional investor information and executing complex financial transactions, LuminArx faces significant cybersecurity and technology infrastructure risks. The firm’s operations depend on secure technology systems for investment analysis, portfolio management, client reporting, and regulatory compliance. Any cybersecurity incidents, system failures, or data breaches could result in financial losses, regulatory sanctions, and reputational damage that would be particularly damaging for a recently established firm seeking to build institutional credibility.
