AltaIR Capital is a US-based early-stage venture capital firm founded by Igor Ryabenkiy. The fund focuses primarily on seed and Series A rounds across technology sectors including fintech, B2B SaaS, and marketplace platforms. While headquartered in the United States, AltaIR has strong operational ties to Eastern Europe and the broader CIS region, which shapes much of its deal sourcing and portfolio geography.
The firm does not publicly disclose assets under management. Based on portfolio breadth and disclosed rounds, analysts estimate AltaIR manages capital in the range of several hundred million dollars, though no official figure has been confirmed. AltaIR participates in crypto and Web3 deals selectively, typically as part of a broader fintech thesis rather than as a dedicated digital-assets fund. Its recorded blockchain and crypto portfolio spans roughly five known investments, reflecting a measured rather than aggressive posture toward the sector.
Notable investments
- Fintech and payments startups – AltaIR has backed multiple early-stage payment infrastructure and neobank projects, primarily targeting underserved markets in Eastern Europe and Central Asia.
- B2B SaaS platforms – A significant portion of the portfolio sits in enterprise software, where AltaIR takes board or advisory seats at seed stage.
- Blockchain-adjacent infrastructure – The firm has made a small number of investments in projects at the intersection of traditional finance and distributed ledger technology, though specific deal names and round sizes have not been publicly disclosed for all positions.
Public information about specific named crypto portfolio companies is limited. The firm does not maintain a regularly updated public portfolio page, and many deals are announced only by the portfolio companies themselves rather than by AltaIR directly. Crunchbase and PitchBook list a broader set of investments across sectors, but crypto-specific entries remain sparse.
Team
Igor Ryabenkiy serves as the founder and managing partner. He has a background in technology entrepreneurship and has been active in the Eastern European startup ecosystem for over two decades. He is a frequent speaker at tech and startup events across Europe and the US. Beyond Ryabenkiy, detailed public information about other partners or investment principals at AltaIR is limited. The firm operates with a lean team structure typical of early-stage funds of its size.
Recent activity
Over the 18 months through early 2026, AltaIR has continued backing early-stage rounds in fintech and SaaS. The firm has not announced a new flagship crypto or Web3 fund during this period. Its approach to digital assets appears opportunistic – participating when a deal fits its broader fintech criteria – rather than thematic. No major exits or write-downs have been publicly reported in the crypto portion of the portfolio.
For founders seeking AltaIR capital in the blockchain space, the fund is most receptive to projects with clear B2B revenue models, fintech applications, or infrastructure tools rather than pure token-economy plays. Its Eastern European network gives it meaningful sourcing advantages in markets that larger US crypto funds often overlook. Investors and founders can find partial portfolio data on Crunchbase and follow fund activity through Igor Ryabenkiy's public profiles on LinkedIn and at startup conferences in Europe and the US.
