Investment Thesis

F4 Fund invests in consumer startups and the infrastructure that powers them, with a focus on backing ‘builder’ type technical founders at the earliest stages. The fund emphasizes hands-on, high-touch support rather than large cohort-based approaches, with the belief that meaningful founder attention and experienced operational guidance drive better outcomes. Their Co-Pilot program reflects a philosophy that founders benefit most from investors who have themselves successfully built, run, and sold companies.

What Sets Them Apart

Low-volume, high-touch support model with no cohorts and only a handful of founders at a time
Fund leadership with proven operating experience - founder David Kaye has 3 successful exits and 2 decades of building experience
Rejection of traditional accelerator model: 'Many accelerators consist of large cohorts run by people who have never successfully built, run and sold a company'
Flexible, customized terms ($100K-$250K initial investment with commitment to support through Series A)
Three-phase structured approach (Plan, Pitch, Process) from inception through institutional funding
Open pitch process with no requirement for warm introductions
