Startup horror stories: when co-founders fall out

Vestd Free Beginner

Concrete proof that the absence of a written agreement is what turns a friendship into a lawsuit. The Zipcar story (a casual 50/50 handshake with no documented expectations, ending in one founder firing the other after 18 months of resentment) and the anonymous 'Tom and James' story (no governance in place, a co-founder drained funds and pushed the company into insolvency, and Tom lost his life savings) are the exact scenarios a 3-page document prevents. Read this before you tell yourself you and your co-founder are too good friends to need paperwork.

  • A handshake 50/50 with no documented commitment expectations is what caused the Zipcar founder fallout, not the split itself
  • Missing corporate governance let one founder withdraw funds disproportionately and sink the company, wiping out the other's savings
  • Every dispute here was avoidable with terms written down before the trouble started, which is the whole argument for signing early
