How Justin Ernest Deployed $500M via SPVs to Back AI Unicorns Without a Traditional VC Fund

AI Summary
Justin Ernest leveraged special‑purpose vehicles to invest nearly $500 million in ten high‑profile AI and deep‑tech startups, bypassing the lengthy process of creating a conventional venture fund. His model gives family offices direct exposure to late‑stage unicorns while building a track record for a future fund.

Justin Ernest, a former Playground Global partner, has funneled almost $500 million into ten late‑stage AI and deep‑tech startups through single‑deal special purpose vehicles, sidestepping the 12‑to‑18‑month process of launching a traditional venture fund.

Ernest’s SPV‑Driven Model Bypasses Traditional VC Fundraising

Instead of forming a formal fund, Ernest created Sabertooth Capital, which raises capital from roughly 30 family offices and smaller institutional investors. Each allocation is packaged into its own SPV, allowing investors to buy shares in a vehicle that holds the target company’s stock. This structure lets Ernest close deals in weeks rather than months.

Nearly $500 Million Deployed Across Ten Late‑Stage AI Startups

In the past 12 months Sabertooth Capital has allocated:

  • $10 million–$275 million per check, securing sizable equity stakes.
  • Investments in Anthropic, Anduril, Base Power, Databricks, PsiQuantum, SpaceX and four other high‑growth firms.
  • One notable exit: Groq’s acquisition by Nvidia for $20 billion, delivering a strong return for Sabertooth’s LPs.

Family Offices Gain Direct Access to High‑Growth AI Unicorns

The SPV approach solves a market gap: family offices want exposure to fast‑moving AI companies but lack the relationships to sit on cap tables. By vetting each deal with the target’s CFO or founder, Ernest provides credibility and peace of mind, especially as companies like Anthropic and Anduril tighten controls on unauthorized SPVs.

Future Outlook: From SPVs to a Full‑Scale Venture Fund

Ernest says the ultimate goal is to raise a traditional fund, using the performance of his one‑off SPVs as proof of concept. Upcoming catalysts—SpaceX’s IPO and Anthropic’s anticipated public listing—could generate additional windfalls, strengthening his track record and attracting larger commitments when he eventually launches a multi‑company fund.
