Top Accelerator Deadlines for Founders: Week of Sept 23, 2026

Two pre-seed accelerators are closing applications this week and next, so here is what founders need to know before the deadlines pass.

Pre-Seed Programs

Both open programs this week target founders at the earliest possible stage, before a team is fully formed and before any institutional capital has been raised.

  • Antler (apply by Sep 30, 2026): A residency program for pre-team founders who need help finding a co-founder and securing a first cheque. Antler is best suited for solo founders or those still searching for the right technical or commercial partner. Apply here

  • Entrepreneur First (apply by Oct 15, 2026): A talent-first program built around co-founder matching, designed for high-potential individuals who want to build a company from scratch alongside another strong operator. Apply here

Seed Programs

No seed-stage programs have open deadlines this week.

Series A Programs

No Series A programs have open deadlines this week.


Founders who already have a rough idea and are actively searching for a technical or business co-founder should prioritise Antler first given its September 30 deadline, then submit to Entrepreneur First before October 15 if they want a second shot at structured co-founder matching with a slightly different network and methodology.
