Founders in their 40s are ~2× more likely to build high-growth firms than founders in their 20s. Survival and growth rates rise with age into the late 50s. —NBER
Founders in their 40s and 50s consistently outperform younger peers on growth and longevity. Despite this, startup success is still widely framed as a young person’s game.
In practice, mid- to late-career professionals bring advantages that matter early. They have deep domain knowledge, experience-informed decision-making, established networks, and a clearer sense of which problems are worth solving.
The early-stage ecosystem, however, is not designed around them. Most early-stage funds, accelerators, and incubators are oriented toward early-career founders, venture-scale outcomes, or narrow technology cycles. That leaves experienced professionals without a path aligned with their reality.
