The problem
Founders are builders. Most start with a product idea and spend months turning it into something that works, before they check whether anyone wants it.
When the product finally meets customers, the most important assumption behind it often turns out to be wrong, and months of work go with it.
How organizations usually handle it
Programs teach lean startup methods in workshops, and founders agree with every slide. Back at their desks the pressure to ship wins, and nobody checks what was actually tested.
How mentoring solves it
A mentor who has built and sold similar products has seen these mistakes before. Meeting every few weeks, they ask the uncomfortable question early: what do you believe that you have not checked yet? Then they help the founder design a small test, and look at the result together.
How it works on Mentornity
A mentor who knows the field
Matching rules connect each startup with a mentor whose expertise fits its product and market.
Assumption Map
Founder and mentor list what must be true for the product to work, and mark which belief is most important and least known.
Experiment Card
Before a test, the founder writes what will count as success. Afterwards the result goes on the card, and the mentor comments.
A next step after every meeting
Every meeting ends with the next step written down, with an owner and a date.
Or a mentor pool, with rules
Not every program needs fixed matches. In a pool program, mentors open their free hours and founders book them themselves. Rules still decide who sees whom: for example, a fintech startup sees only mentors with finance experience.
What you can measure
Your team sees which mentoring tools each startup worked through and how founders and mentors rate their meetings over the program.
Questions
What are mentoring tools?
Short structured exercises a mentor sends to a mentee, such as the Assumption Map or the Experiment Card. The mentee fills them in, and the mentor comments.
Do mentors need training to use them?
No. Each tool explains itself in a few minutes. Mentors who want more can take courses in Mentornity Academy.
