Solo-Founded Startups Climb to 36.3% as AI Agent Stacks Cut Costs 95%-98%

Summary
36.3% of new startups were solo-founded by mid-2025, up from 23.7% in 2019, as AI agents turned one-person company building into a mainstream software playbook.
$3,000-$12,000 a year now buys a full AI agent stack versus $80,000-$120,000 a month for a comparable junior human team, letting founders replace four to six hires with $300-$500 monthly tools.
$80 million sale of Base44, built by one founder with zero employees until the final week, gave the model a concrete proof point after the product reached nearly $1.5 million revenue in one month.
Developer tools, automated customer service and proprietary trading fit best because AI handles predictable software-heavy tasks, while enterprise sales, regulated sectors and rising compute bills create ceilings around roughly $1 million-$3 million ARR.
48% of angel investors backed at least one solo-founder startup in 2025, but more than 75% of VC funds made none, suggesting bootstrapping and angel capital remain the likelier path until larger exits reset investor assumptions.
