What Open Doors Partners does
Open Doors Partners is a private investment firm founded in 2017 and domiciled in Delaware, operating from the San Francisco Bay Area with a 1-10 person team. The firm structures individual Special Purpose Vehicles (SPVs) under a Delaware Series LLC framework and offers deal-by-deal participation in private market opportunities to accredited investors, family offices, and qualified purchasers under SEC Rule 506(b) of Regulation D. Since inception, the firm has launched 30+ SPVs and brings 6-9 vetted opportunities per year across venture, private credit, real estate, secondaries, and emerging technology, with average hold periods of 3-4 years.
The core product is the Series SPV platform itself: each investment is ring-fenced in a distinct Delaware Series LLC entity with independent reporting, K-1 tax reporting, and Self-Directed IRA compatibility, enabling full deal-level visibility and eliminating blind-pool risk. An investor portal with referral mechanics serves verified network members, and an Insights blog publishes institutional-grade thought leadership on private-market topics including AI infrastructure economics, 72-hour deal velocity, and the rise of secondaries. The current active offerings include Series ZaiNar (Physical AI primary) and Series Revolut (European fintech secondary), and the representative portfolio spans 18+ companies including SpaceX, Anduril, OpenAI, Perplexity, Lambda, Cerebras, Crusoe, Replit, Boom Supersonic, Aven, Virta Health, Kalshi, Valar Atomics, Impulse Space, Opendoor, and Arcline, with co-investors including SoftBank, General Atlantic, Founders Fund, Khosla Ventures, Y Combinator, and Norwest Venture Partners.
The business model is a traditional private-fund economics structure: management fees on committed/deployed capital plus 20% carried interest on realized gains, earned through SPV-based private placements distributed exclusively via direct relationship-based outreach with no general solicitation. The firm is led by Managing Partner Pramod Dabir (ex-Goldman Sachs, TA Associates; founder of West Agile Labs) and Partner Ravi Chiruvolu (ex-NASA, McKinsey, Alta Partners, Charter Venture Capital; led a 250x+ exit at Ellie Mae). Customer segments include family offices and accredited investors (primary), private companies seeking co-investment capital, funds and GPs seeking aligned LP capital, and sell-side institutions seeking liquidity for secondary positions.
