How Justin Ernest invested nearly $500M into hot startups without a traditional VC fund

What happened

Justin Ernest, founder of Sabertooth VC, managed to invest nearly $500 million in top startups like Anthropic, Anduril, and SpaceX without creating a traditional venture capital fund. Instead of spending months or years raising a formal venture fund, Ernest tapped into a captive network of limited partners (LPs) who trusted him to deploy capital quickly into high-potential startups. This approach sidestepped the typical fundraising cycle, allowing more agile and direct investment decisions.

Why it matters

Ernest’s model pressures the conventional VC fundraising timeline by eliminating the long fundraise process and quarterly fundraising pressures. It shows that founders and experienced investors can marshal substantial capital through trusted LP networks without formal fund structures, reducing overhead costs and bureaucracy. This strategy can accelerate deal flow and decision-making speed, increasing exposure to breakthrough startups while limiting time spent on fundraising. However, it also shifts more risk onto relationships and informal agreements, which may limit scalability or invite governance challenges.

What to watch next

It will be important to track if other investors adopt similar captive LP network models and how those structures hold up under pressure from increased regulatory scrutiny or LP demands for transparency. Also, watch how this approach affects early-stage startups seeking capital—whether they benefit from more flexible timing or face new risks from less structured funds. Finally, see if Sabertooth VC’s method influences the traditional VC sector’s fundraising cycles and governance standards over time.
