VCs and Superhuman Mail Founder Outline Product-Market Fit Red Flags

At TechCrunch Disrupt last week, Iconiq partner Anu Bharadwaj, Sapphire Ventures partner Rajeev Dham and Superhuman Mail founder Rahul Vohra discussed how startups can assess product-market fit in the AI era. Bharadwaj said getting companies to try a product in pilots has become easier, while moving from pilots to production remains difficult.

Bharadwaj warned that founders should clarify whether reported revenue is annual recurring revenue (ARR) or an annualized run rate. Counting short-term pilot customers as if their revenue would continue for a full year can make a business look stronger than it is. She said companies should be candid about revenue quality and distinguish hype from reality. Red flags include relying on a few customers for much of revenue or customers being able to switch vendors for a lower price, factors she linked to churn and retention.

Vohra advised startups to track customer engagement and dollar retention, and to set benchmarks for their market. At Superhuman, he said, the company tracked ARR alongside an internal measure called “delighted ARR,” which counted revenue only from highly engaged customers. He said this helped assess customer loyalty and how long customers might stay.

For gauging customer attachment, Vohra suggested asking how people would feel if they could no longer use a product. He said startups scoring 13%, 14% or 15% or below should consider a complete pivot, while those at 20% could optimize toward 40%. Dham cautioned that a founder’s vision is not the same as a sound business. The panelists said product-market fit must be continually earned, even at a billion dollars in revenue.
