What LuminArx Capital Management LP does
LuminArx Capital Management LP is a privately held, Delaware-domiciled alternative investment manager founded in 2023 and headquartered at 712 Fifth Avenue, New York. The firm is led by Co-Founders and former Blackstone Alternative Asset Management (BAAM) Co-Chief Investment Officers Gideon Berger (CEO) and Min Htoo (CIO), supported by a 30+ person team drawn predominantly from Blackstone BAAM, Citadel, Magnetar, Goldman Sachs, Carlyle, Citigroup, Millennium, and other tier-one alternative investment platforms. The firm focuses on capital solutions investing — flexible, bespoke structured financing for high-quality counterparties — targeting consistent returns with downside mitigation and low correlation to traditional markets.
The firm operates through direct principal investments, dedicated capital vehicles, and co-investments alongside leading institutional investors. Disclosed products include SkyLight Aero Finance, a $1 billion secured-debt platform for commercial aviation lending (launched January 2026 with SkyWorks Holdings), and Cinergy, a strategic private lending vehicle launched in partnership with Citigroup in January 2024. LuminArx has led or co-led headline transactions including Sierra Space's $550 million Series C (March 2026, $8 billion post-money valuation), Nscale's €1.1 billion ($1.4 billion) Delayed Draw Term Loan (February 2026), and Vultr's $333 million financing at a $3.5 billion valuation (December 2024), alongside participations in Axiom Space ($350 million), Upgrade ($165 million Series G), and Axonic Insurance ($210 million preferred equity).
The revenue model is institutional asset management: management fees on third-party and balance-sheet capital plus performance fees / carried interest on equity-linked investments. Distribution is conducted through direct institutional relationships with sophisticated investors, family offices, and corporate counterparties via the firm's network and a secure Intralinks investor portal. The firm's stated differentiator is its ability to provide creative, structurally engineered capital solutions with narrowed outcome distributions — a function of the founders' track record at BAAM (where client assets grew from approximately $1 billion to approximately $80 billion) and the team's breadth across credit, equity, structured finance, and special situations.

LuminArx Capital Management LP competitors and assessment
Company assessmentBroad incumbents
- Blackstone Alternative Asset Management (BAAM): The predecessor platform of LuminArx's two founders and the largest scalable 'multi-alternatives' and capital solutions franchise in the market. Directly comparable because both Berger and Htoo were Co-CIOs at BAAM, and LuminArx's stated 'reimagined approach to capital solutions' is explicitly a riff on BAAM's strategy.
- Apollo Global Management (Hybrid Value / Capital Solutions): Mega-alternatives platform with a dedicated Hybrid Value and capital solutions franchise providing structured equity and debt to corporates. Comparable to LuminArx in pursuing asymmetric, structured capital solutions for complex situations, but at vastly greater scale and breadth.
- Ares Management: Large alternative asset manager with deep credit, structured finance and asset-based lending capabilities. Comparable in its emphasis on credit-led capital solutions and platform-style origination, though at a much larger and more diversified scale than LuminArx.
Direct peers
- HPS Investment Partners: Large, established alternative credit and capital solutions manager offering flexible, bespoke financing across the capital structure with low correlation to traditional markets. Closely mirrors LuminArx's stated thesis of structured, theme-driven capital solutions for high-quality counterparties.
- Sixth Street Partners: Global investment firm focused on bespoke, theme-driven capital solutions including direct lending, asset-based finance, and strategic equity. Highly comparable to LuminArx in offering creative, flexible financing across capital structures to a similar institutional and corporate client base.
- Sculptor Capital Management: Multi-strategy alternatives manager pursuing opportunistic, often structured credit and special situations across capital structures. Comparable to LuminArx in delivering low-correlation returns via bespoke, situational investing rather than directional asset-class exposure.
- Anchorage Capital Group: Special-situations and opportunistic credit manager with a focus on flexible, structured capital solutions for corporates and asset-heavy situations. Highly comparable to LuminArx's stated focus on high signal-to-noise, structurally protected outcomes.
- Onex Partners: Special-situations-oriented alternative investment platform providing flexible capital across the capital structure to industrial and asset-heavy businesses. Comparable to LuminArx in pursuing bespoke capital solutions, including aviation and asset-based transactions similar to LuminArx's SkyLight Aero Finance.
- Comvest Partners: Middle-market alternative investment manager focused on direct lending, special situations, and structured capital solutions for business owners and management teams. Comparable to LuminArx in offering flexible, thematic capital structures for non-vanilla situations.
- Marathon Asset Management: Global credit and asset-based finance specialist offering structured credit, private credit and asset-backed solutions. Comparable to LuminArx in its emphasis on asset-backed, structured solutions (e.g., aviation, infrastructure) and creative cross-cycle capital deployment.
