just don't die mantra tarpit ideas when to pivot talking to customers startup fundamentals not losing hope

Episode Summary

Dalton Caldwell, who has worked with more startups than nearly any human alive through 21 YC batches and 20+ unicorns, shares deeply practical startup wisdom centered on his 'just don't die' mantra. He introduces the concept of tarpit ideas that trap founders with false positive feedback, explains how to know when to pivot vs persevere, and argues that the fundamentals — sell, make money, talk to customers — matter more than anything else.

Leadership Principles

  • Just don't die — being coached and reminded of the fundamentals puts you in the right mindset for survival
  • Tarpit ideas seem like unsolved problems and get positive feedback, but people have been starting that startup since the '90s — avoid them
  • Sell shit, make money — the most pragmatic startup advice is also the most important
