How One Investor Deployed $500M Into AI Startups Without Raising a Traditional Fund
Justin Ernest, founder of Sabertooth VC, invested nearly half a billion dollars into hot startups like Anthropic, Anduril, and SpaceX without spending a year building a formal venture capital fund. Instead, he tapped into a ready-made network of wealthy investors—called limited partners—who trusted his judgment enough to back his picks directly.
This approach skipped the traditional playbook where investors spend months pitching to rich individuals, foundations, and institutions to raise a formal fund. Ernest simply identified promising startups and presented opportunities to his existing connections, who committed capital on a deal-by-deal basis.
Why This Matters to Small Business Owners
This story reveals how the rules of startup investing are shifting away from traditional gatekeepers. For small business owners seeking funding, it shows that investors are becoming more agile and less bureaucratic. You don't need a perfect pitch to a formal fund anymore—access to capital is increasingly about relationships and track record.
It also highlights the power of AI and defense tech as investment categories. These sectors are attracting serious money at lightning speed, and they're reshaping what technologies trickle down to small businesses. The startups Ernest backed will likely become infrastructure that affects your operations within a few years.
More broadly, this demonstrates that capital flows fastest to people with existing networks and credibility. If you're building a business, cultivating relationships with experienced investors and mentors now—before you need money—puts you in a stronger position later.
What to Watch
Keep an eye on whether more investors follow Ernest's model. If traditional venture funds become slower or more risk-averse, smaller pools of capital moving quickly could reshape which startups succeed—and which emerging technologies reach your small business first.
