The a16z podcast features an interview with Jean-Denis Greze, former CTO of Plaid, and Alex Rampell.

The US venture capital firm Andreessen Horowitz (a16z) has released a new podcast episode featuring Jean-Denis Greze, former Chief Technology Officer of fintech company Plaid, and Alex Rampell, a partner at a16z. This episode focuses on startup strategy adjustments in the AI era, particularly how entrepreneurs should make decisions when a seemingly successful business faces structural ceilings.
According to the official episode description, Jean-Denis Greze previously founded an AI tax product for small businesses. The product generated nearly $1 million in revenue in its first year and was on track for $2.5 million to $3 million in subsequent years. However, Greze ultimately chose to shut it down. His reasoning was that as AI technology becomes more widespread, incumbents could use the same technology to automate tax preparation for their existing customers faster than a startup could win market share, preventing the company from reaching the 'venture scale' required by investors. Additionally, tax services are sold once a year, leaving a very short window for pivoting.
After shutting down the original project, Greze pivoted his team and technical capabilities to Town, an AI assistant that works from your email and calendar. The episode description notes that Town found product-market fit quickly enough that Ben Horowitz, co-founder of a16z, messaged Alex Rampell to say it 'changed my life,' without knowing whose company it was.
The interview also covers several listed topics, including why a profitable business can still be the wrong business to build, how to know when to kill something that's working, Town as a token-allocation machine, horizontal vs. vertical competition, and what agents mean for Amazon, advertising, and the future of shopping. For professional readers interested in AI application-layer startups, product positioning, and exit strategies, this episode offers specific case studies hosted by a renowned investor and participated in by an experienced founder.
