Investor Reference Checking

Investor reference checking is the founder practice of evaluating investors as long-term company partners rather than treating every check as interchangeable. In Yuri Sagalov on AeroFS, YC, Angel Investing, and Wayfinder Ventures, Yuri Sagalov advises founders to ask investors for references, including from companies where the relationship or outcome did not work well.

The source frames the practice as normal and even positive. Asking for references can signal that the founder is thoughtful about governance, pressure, and future hard moments. It also pairs with Sagalov’s own AeroFS story, where he says investors did not force the Redbooth merger and where many AeroFS investors later became LPs in Wayfinder Ventures.

Serena & Lily: Serena Dugan and Lily Kanter. They Built a $20M Brand—Then One Investor Almost Destroyed It adds the downside consumer-brand version through Serena & Lily. Lily Kanter says harsh terms become more likely when founders badly need money and investors can see that need; the episode’s Bad Money and Liquidation Preference Stack arc shows why founder diligence should include how an investor behaves under stress, not only whether they can fund a round.

Key Claims

  • Investor quality is best judged in difficult periods, not only from successful portfolio companies.
  • Reference checking should include downside cases because company-building relationships are tested by misses, delays, pivots, and shutdowns.
  • Thoughtful reference requests can improve founder-investor fit rather than insult the investor.
  • The practice complements Founder-Investor Learning because good investors should want founders to understand the relationship they are entering.
  • Reference checking is most useful before cash pressure becomes acute enough that founders lose the practical ability to reject weak terms.
