TechCrunch Disrupt 2026 is leaning into a problem most startups would love to have: what changes when a product stops being a product for a few early users and becomes something billions of people rely on? That’s the premise of a Builders Stage fireside chat with Robby Stein, Google Search’s vice president of product, built around a simple but loaded shift: from MVP thinking to decisions made at real scale.
The session is aimed at founders, but not in the generic “copy Google” sense. The point is more practical than that. Once a product has a huge audience, speed still matters, but so does trust. So does not breaking the thing people already depend on. Stein’s conversation will focus on where early instincts still help, and where they stop being enough.
His background fits the topic neatly. Stein co-founded Stamped, a social recommendations startup that was acquired by Yahoo, then spent five years at Instagram working on Stories, Feed, Direct Messaging, and Reels. He later became head of product at Artifact, an AI-powered newsfeed, before returning to Google in 2024. That mix gives him both the founder’s view and the operator’s view.
And right now, he sits at a very particular crossroads inside Google Search. He works on generative AI products and experiences, and Google said in May that AI Mode had crossed 1 billion monthly users, a year after launch. Earlier this year, Stein described updates that let people move from an AI Overview into a follow-up conversation in AI Mode, which is exactly the kind of product shift where usefulness and caution have to coexist.
Disrupt itself is set for Moscone West in San Francisco from October 13 to 15, with more than 10,000 startups, investors, and tech decision-makers expected. The event says it will feature more than 250 speakers across 200+ sessions, plus roundtables, breakouts, the Expo Hall, Startup Battlefield, and networking. For anyone building with AI, or just trying to keep a product usable as it grows, that’s the real hook here: the hard part isn’t getting started. It’s knowing when the playbook has to change.
My take — AI-written commentary, not fact-checked reporting
The startup world loves celebrating speed, then acts shocked when scale demands restraint. That’s not a contradiction; it’s the job. The uncomfortable truth is that “move fast” is a great slogan until billions of people are the ones catching the fallout.
