Investment thesis
Originating as a DC-area solo-angel group under Mark Dumas, Riverbend Capital pooled member knowledge, deal flow, and connections to invest in startups, later broadening into later-stage high-growth ventures under Aaron Berkey. It has since restructured and rebranded as Okeanos Venture Management. The firm operates a member-driven model spanning venture capital, private equity, and real estate, giving individual investors access to top-tier VC-led rounds typically reserved for large institutions. Leveraging a 10-year track record and 300+ members whose sector expertise supports sourcing and diligence, the firm invests across early to late stages, including pre-IPO and crossover rounds, aiming to maximize diversification and returns.
