Accelerator Deadlines to Know: Week of October 7, 2026

One key accelerator deadline falls this week, and pre-seed founders looking for a co-founder should act before October 15.

This week is light on volume but heavy on importance for a specific type of founder: those who have not yet found a technical or business co-founder and want a structured program to help them do it. One deadline closes in the next eight days, so read carefully and apply early.

Pre-Seed

  • Entrepreneur First (Apply by Oct 15, 2026): A talent-first accelerator that accepts individuals before they have a co-founder or even a fixed idea. EF brings together ambitious people, helps them find a co-founder through a structured matching process, and then funds the resulting company at the pre-seed stage. Ideal for high-potential operators, researchers, and engineers who want to build a venture-scale company but need the right partner to do it with. Apply here

Seed

No seed-stage programs with deadlines this week. Check back next week for upcoming seed rounds and accelerator cohorts targeting companies with early traction.

Series A

No Series A programs with deadlines this week. Founders at this stage should use the coming days to prepare materials for programs expected to open in Q4 2026.

How to Prioritise This Week

If you are a pre-product, pre-team founder with a strong background in a technical or research domain, Entrepreneur First is one of the few programs designed specifically for you, making it the obvious priority this week. Founders who already have a co-founder and initial traction should monitor upcoming seed-stage deadlines rather than stretching to fit a program built for an earlier stage.
