From first users to billions: Google’s Robby Stein joins TechCrunch Disrupt 2026

Getting people to try your first product is one challenge. Changing a product that billions of people already rely on is another. The ambition is still to move fast, test ideas, and build something better. But when every update carries consequences at a global scale, the instincts that helped you get started may need an update of their own.

That tension is at the center of this Builders Stage session, “From MVP to Billions of Users: How Product Decisions Must Change at Scale,” a fireside chat at TechCrunch Disrupt 2026 . Led by Robby Stein, vice president of product for Google Search, this session explores how product teams balance speed with trust, and innovation with reliability, when their decisions affect billions of users.
