The “Sent via Superhuman iOS” email signature has become one of the strangest flexes in the tech industry, but its influence is enduring, as the $30 per month invite-only email app continues to shape how a wave of personal productivity startups are building their business and product strategies.
I had a chance to chat with Superhuman CEO and founder Rahul Vohra last week during an oddly busy time for him. He had just announced a dedicated $7 million angel fund with his friend Todd Goldberg (which I wrote up here) and we also noted that LinkedIn is killing off Sales Navigator, a feature driven by Rapportive, which Vohra founded and later sold in 2012. All the while, his buzzy email company is plugging along, amassing more interested users. Vohra tells me there are now more than 275,000 people on the waitlist for Superhuman.
Below is a chunk of my conversation with Vohra, which has been edited for length and clarity.
TechCrunch: When you go out to raise funding and a chunk of your theoretical user base is sitting on a waitlist, is it a little tougher to determine the total market for your product?
Rahul Vohra: That’s a good question. When we were doing our Series B, it was very easily answered because we’re one of a cohort of companies, that includes Notion and Airtable and Figma, where the addressable market — assuming you can build a product that’s good enough — is utterly enormous.
With my last company, Rapportive, there was a lot of conversation around, “oh, what’s the business model? What’s the market? How many people need this?” This almost never came up in any fundraising conversation. People were more like, “well, if this thing works, obviously the market is basically all of prosumer productivity and that is, no matter how you define it, absolutely huge.”
