Why the First Week of an Accelerator Matters So Much
Founders join an accelerator for capital, mentors and access, but they often say the most valuable thing was the cohort. That only happens if founders learn to trust each other early. A first week of lectures produces polite strangers; a first week of shared, slightly uncomfortable decisions produces peers who call each other at midnight.
Good week-one activities have three things in common: every founder participates, the stakes are low enough to be honest, and the discussion surfaces how each founder actually makes decisions — not how they pitch.
8 Activity Formats for Week One
• 1. Startup simulation run. Every founder plays the same 20-turn run in Founder Runway, then the cohort compares outcomes and the decisions behind them. 60 minutes including debrief.
• 2. Runway reveal. Each team writes its real runway in months on a card. Cards are shuffled and read out anonymously, which makes it safe to talk about cash.
• 3. Decision post-mortem pairs. Founders pair up and walk each other through the hardest decision of the last six months.
• 4. Customer-call swap. Teams sit in on each other's customer calls and report back what they heard that the founder did not.
• 5. One-metric commitment. Each team picks the single metric it will move during the programme and says it out loud to the room.
• 6. Investor-question drill. Mentors ask the five questions investors ask most; founders answer in 60 seconds each.
• 7. Failure stories evening. Alumni or mentors share one decision that went wrong and what it cost.
• 8. Office-hours speed rounds. Ten-minute slots, one specific question per founder, rotating mentors.
How to Run the Simulation Session for Founders
Experienced founders do not need the vocabulary explained, so skip the teaching and fix the conditions instead: same sector, same business model, same starting stage and a harder difficulty such as low cash or a competitive market. Give 30 minutes of play and 25 minutes of debrief.
In the debrief, ask the questions that are hard to ask about real companies: when did you raise, and was it because something worked or because cash scared you? Which customer did you let shape the roadmap? Founders reveal their real instincts more freely about a simulated company than about their own — which is exactly what mentors need to see early.
| Student group | Accelerator cohort | |
|---|---|---|
| Difficulty | Normal | Low cash or competitive market |
| Teaching time | Explain runway, burn and PMF | None — go straight to play |
| Debrief focus | What each metric means | Fundraising timing and focus instincts |
| Outcome for organisers | Concept learning | Early read on each founder's decision style |
Using Simulations in Pre-Accelerator Programmes
Pre-accelerator and university incubator participants usually have an idea but no company yet. For them, the simulation does double duty: it introduces runway, burn, MRR and product-market fit, and it gives them a feel for the sequence a company moves through from Pre-Seed toward Series A.
A simple pattern is to run the simulation in week one and again in the final week with the same setup. The difference between the two runs is a concrete, shareable measure of what participants learned.
Measuring Whether Week One Worked
Do not measure satisfaction scores alone. Ask in week four: how many founders have spoken to another team about a real problem without being prompted? How many shared their actual runway number with a peer? Those two numbers tell you whether the cohort became a network.
Frequently asked questions
What activities work best in the first week of an accelerator?
Formats where every founder participates and makes or discusses real decisions: a startup simulation run, an anonymous runway reveal, decision post-mortem pairs, customer-call swaps and investor-question drills.
Why use a startup simulation with experienced founders?
Founders discuss their instincts more openly about a simulated company than their own. A shared run with fixed conditions shows mentors how each founder approaches fundraising timing, focus and spending — early in the programme.
How long should a simulation session take for a cohort?
About an hour: a few minutes to set conditions, 30 minutes of play and around 25 minutes of debrief focused on decisions rather than scores.
Can pre-accelerator programmes use startup simulations?
Yes. Running the same setup in the first and last week gives participants a concrete measure of what they learned and introduces the core metrics before they have a company of their own.
