The 4-Time Exited Founder Going for the Fifth (Peter Pezaris)

// TRANSMISSION

In this episode, I'm joined by Peter Pezaris, a four-time exiting founder now building his fifth, Vortex Software, out of San Francisco. Peter walks us through 25 years of building with the same Carnegie Mellon crew — starting with Commissioner.com (the first fantasy sports platform on the web, sold to what became CBS Sports), through Multiply (a social newsfeed launched in 2003 — before Facebook had one — that briefly led the social network race in several countries), to Glip (launched the same month as Slack with a nearly identical product, sold to RingCentral), and most recently CodeStream (a YC company sold to New Relic). Two of those almost became category-defining giants. The reflection on what kept them from the monster outcome — including 25 years building from Delray Beach, Florida instead of the Bay Area — is the thread that drove the move to San Francisco for Vortex. We dig into Vortex itself: a drop-in plugin (think Stripe, but for team-invite flows) that turns the moment a single user invites their team into a real conversion engine. The industry average freemium-to-paid rate is 5.5%; Slack hits 30%, CodeStream hit 33% — and Peter's research across 200+ companies says the team-invite flow is the single biggest blind spot in PLG. Vortex automates the experimentation: one customer's invite conversion jumped from baseline +26% on day one, then to +31% as Vortex's agent ran A/B tests on copy, timing, and channels. Peter closes with the cleanest founder advice I've heard in a while: did you spend more time on your startup this week than last week? If yes for several weeks running, you have a real company. If not, it's a hobby.
