Elad Gil: When do you know you have Product Market Fit?

Signs of Product-Market Fit

• High Usage Despite Technical Failure

  • Active usage or high retention rates on a "broken" product indicate strong product-market fit.
  • Example: Twitter maintained massive user adoption in its early years despite frequent outages and downtime.

• Organic Adoption by Major Brands (SaaS Context)

  • Big brands discovering, using, and paying for a SaaS product organically serve as a validation signal.
  • Specific Examples Cited:
    • PagerDuty: Secured early enterprise customers such as Apple.
    • Zeplin: Adopted early by Facebook and other major organizations.
    • Airtable: Experiences broad adoption across various large brands.

• Intense Customer Feedback from Early Users

  • Receiving "love letters" or deeply emotional testimonials from a small user base signals strong value proposition.
  • Case Study: Color
    • Mission: Provided users with information regarding hereditary risks for genetically driven cancers.
    • Feedback: Users sent emails expressing gratitude for affordability and potential life-saving impact.
    • Outcome: This strong emotional connection occurred even when the company was in its early stages with a limited user base.
