Why talk to other founders

Most problems an early-stage founder runs into, like pricing, a first hire or a difficult investor term, someone a year or two ahead has already dealt with. A thirty-minute conversation with them can replace weeks of guessing.

Founder conversations also lead to things you can't plan for: an introduction to an investor, a co-founder, a first customer, or a partner for an event.

Who to talk to

Founders a stage ahead

They remember your current problems clearly and can tell you what mattered in hindsight.

Founders in your industry

Useful for suppliers, regulation, sales channels and which investors know the space.

Potential co-founders

Conversations are the first step in testing whether you'd work well together.

Mentors

Experienced operators who can give structured advice over several sessions.

Investors

A short, specific message can lead to a meeting, especially when your profile shows traction.

How to write a first message that gets a reply

  • Say who you are and what your startup does in one sentence
  • Explain why you're contacting this person in particular
  • Ask one specific question, not "can I pick your brain?"
  • Keep it short enough to read on a phone
  • Make it easy to say yes, for example by suggesting a 20-minute call
