Brief

Jean‑Denis Greze, cofounder and CEO of TownAI, appears on Luba Yudasina’s walk‑and‑talk to explain leaving Plaid’s C‑suite at 45, converting a scrapped tax‑prep project into a $55M Series A a16z‑backed startup, why he killed a revenue business to chase scale, and why Town is an onboarding layer (not an "AI assistant") that lets ordinary users use AI without prompts.

Why it matters

Jean‑Denis Greze, former CTO of Plaid who led engineering through a blocked $5.3B Visa acquisition, left the C‑suite at 45 and turned a scrapped AI tax‑prep startup into TownAI, a $55M Series A company backed by Andreessen Horowitz (a16z).

Key details

  • TownAI is positioned as an onboarding layer for nontechnical users — Greze refuses to call it an "AI assistant" — designed to give people leverage from AI without writing a single prompt.
  • Greze and his cofounder deliberately killed a revenue‑generating tax‑prep business in one week because it wouldn’t be a "rocket ship," and he uses an "accelerators, table stakes, foundations" framework to stay ahead of OpenAI, Gemini, and Google.

One of my favorite founders @jgreze of @TownAI in one of my favorite podcast formats, the walk-and-talk with @LubaYudasina!

1000% more interesting to watch than two people sitting across from each other at a table.

Today I walk with @jgreze, co-founder and CEO of @TownAI, an AI on-ramp platform for individuals and businesses. Jean-Denis is the former CTO of @Plaid, led engineering through a blocked $5.3B Visa acquisition, and walked away from the C-suite at 45 to start over from zero, and now he's turned a scrapped AI tax-prep startup into a $55M Series A company backed by Andreessen Horowitz(@a16z). He gets into the week he decided to kill a business that was actually working, and why he refuses to call Town an "AI assistant."

We get into:

  • Why he waited until 45, after seven years as Plaid's CTO, to become a founder for the first time

  • The week he and his co-founder killed a working, revenue-generating tax-prep startup because it wasn't going to be a rocket ship

  • Town's real bet: not a smarter AI assistant, but an onboarding layer that gets normal people leverage from AI without writing a single prompt

  • His "accelerators, table stakes, foundations" framework for staying ahead of OpenAI, Gemini, and Google

  • Why turning "uncool" work into cult culture, from Dropbox's Team Cash to Plaid's colourful tights, built teams that stuck around

so much more!
