River Bend Capital

Managing Partner Aaron Berkey leads thesis development and investment selection alongside founder Mark Dumas. The firm deploys a collective diligence model where its 200+ members, who are active business operators, contribute sector expertise to evaluate prospective deals. Final investment decisions are made by the management team with member input.

The firm sources through longstanding personal relationships with top syndicate networks, VC and PE funds, and real estate development partners. Additionally, its membership base of over 200 operators across technology, government contracting, professional services, real estate, and consulting generates proprietary referrals and co-investment opportunities.

River Bend Capital operates as a membership-based private investment manager under the Okeanos Venture Management brand, not a single-family office or traditional venture firm. It pools capital from a national network of over 200 accredited individual investors to co-invest across venture capital, private equity, and real estate.

The firm's membership model funds direct co-investments across VC, PE, and RE, including access to top-tier VC-led rounds typically reserved for large institutional funds. While it emphasizes direct participation in individual company rounds, its relationship network may include fund-level interactions; the firm's publicly stated focus is on transaction-level co-investment.

River Bend Capital is stage-agnostic, deploying from early-stage seed and startup rounds through expansion, late-stage growth, and pre-IPO or crossover rounds. The firm also balances these venture allocations with more risk-averse private equity and real estate opportunities to manage liquidity horizons and return profiles.
