A sprint for cofounders who've just matched.

4 weeks to validate fit before talking equity and commitment.

The Cofo Sprint is a structured 4‑week “trial project” for two people who are considering cofounding together.

You bring any idea (or pick a simple one), we scope a small, shippable outcome and run it like a real sprint with clear roles, weekly commitments, and async accountability.

By the end, you’ll have real data on how you work together. Communication, pace, ownership, decision-making, not just good vibes from calls.

Get Started

The cofounder trap is real

25 intro calls, 6 months wasted. Endless chats, no progress.

Wrong fit kills startups faster than bad ideas.

You need proof your co-founder can ship, communicate, and align, not just talk.

What you get

Clarity on working styles, reliability, decision-making.

Tangible output (landing page, prototype, experiments).

Neutral facilitation - no bias, just results.

How it works

You bring your idea (any stage). Your moderator scopes a 4-week MVP sprint with both of you. You execute together.

Week 1: Scope & alignment

Define roles, success criteria, and “definition of done.”

Kickoff call + sprint plan + first tasks.

Week 2–3: Build & momentum

Review output and the working dynamic, then decide what’s next.

Demo + retro + clear next step.

Week 4: Ship & decide

Execute together with frequent check-ins and async updates.

Twice-weekly 30‑min calls, Slack + Trello, weekly tasks.

Get Started

We run async-first (Slack + Trello) with two mandatory 30‑minute calls per week, scheduled around both calendars. The goal isn’t perfection - it’s proof of working compatibility under real constraints.

Pricing

It's free - currently community-driven and moderated by Alex.

We keep Cofo Sprint intentionally small and selective, because the format only works when both people show up and follow through.

To join, we’ll ask a few quick questions and do a short intro check to make sure you’ve both aligned on time commitment, expectations, and that you’re genuinely ready to run a 4-week “test drive” together.

If it’s not the right moment, we’ll say no (or suggest when to come back), so the pairs we accept get a serious experience, not another half-start that fades out.

We’re actively adding pre-seed investors and angels to the Cofo Sprint community, and we’re also building relationships with accelerators by location.

For founders, early relationships matter: even if an investor doesn’t commit immediately, they often stay close and re-engage once progress is real and consistent.
