First Principles Club - Founder Assumption Check 02
Before you build, check the belief.
Every startup decision rests on something you believe.
“Our customers will pay for this.”
“A lower price will bring more sales.”
“We need to hire before we can grow.”
What evidence supports that belief?
Founder Assumption Check is a live, interactive online session by First Principles Club for early-stage founders to examine the thinking behind a real business decision.
Bring one belief behind your product, customer, pricing, hiring, or growth. We’ll use first principles thinking to separate what you know from what you assume and identify what you should investigate next.
Who is this for?
Aspiring founders exploring a business idea
Founders building a product before their first sale
Early-stage entrepreneurs deciding what to do next
What will you leave with?
A clearer view of the assumptions behind your decision
A sharper question to investigate
A practical next step to gather evidence
What should you bring?
One real business question. No pitch deck needed—just a willingness to examine your thinking and participate.
