From MVP to Billions: Google’s Robby Stein to Discuss the Evolution of Product Strategy at TechCrunch Disrupt 2026

For every entrepreneur, the journey begins with a singular, driving focus: getting the first version of a product—the Minimum Viable Product (MVP)—into the hands of users. This early phase is characterized by rapid iteration, high-stakes experimentation, and the thrill of discovery. However, as a product matures and reaches a global scale, the rules of engagement shift dramatically. When a platform is relied upon by billions of people, the agility that once fueled growth must be balanced against the crushing weight of global responsibility.

This tension between the instinct to innovate and the mandate to maintain absolute reliability is at the heart of an upcoming fireside chat at TechCrunch Disrupt 2026. The session, titled “From MVP to Billions of Users: How Product Decisions Must Change at Scale,” will feature Robby Stein, vice president of product for Google Search. Taking the stage at the Moscone West in San Francisco, Stein will offer a deep dive into the complex, often contradictory realities of managing products that serve a significant portion of the global population.

The event, which runs from October 13 to October 15, serves as a nexus for the global startup ecosystem, drawing over 10,000 innovators, investors, and decision-makers. As the industry faces a period of rapid technological transformation, particularly with the integration of artificial intelligence into daily workflows, Stein’s perspective provides a critical roadmap for leaders navigating the treacherous bridge between startup agility and enterprise-grade stability.

The Challenge of Growth: Outgrowing the Original Playbook

The fundamental dilemma for any scaling company is how to maintain a culture of experimentation when the consequences of a mistake are no longer local or contained. Early-stage teams are often encouraged to "move fast and break things." Yet, at the scale of Google Search, "breaking things" is not a viable strategy. The challenge lies in introducing novel features—such as generative AI—without undermining the core utility that users have come to depend on for their daily information needs.

Stein’s session is designed to unpack this transition. It is not intended as a rigid blueprint for copying Google’s internal processes, but rather as an exercise in critical thinking. For the founders and product managers in the audience, the value lies in dissecting the decision-making framework: identifying where speed still offers a competitive advantage, determining when caution becomes the ultimate priority, and recognizing the inflection points where a company’s methodology must fundamentally evolve to survive its own success.

The discussion will explore the nuance of building for a global audience. When a product reaches billions of users, the diversity of the user base means that even minor updates can have outsized, unpredictable impacts. Managing this complexity requires a shift from a founder-led, intuition-driven approach to a more data-informed, risk-mitigating philosophy—without losing the soul of the original innovation.

A Career Defined by Scale and Iteration

Robby Stein’s insights are rooted in a career that has spanned the entire spectrum of the product lifecycle. His experience is not confined to the halls of a tech giant; he possesses the battle-hardened perspective of a founder who has lived through the trenches of early-stage development.

Stein co-founded and led Stamped, a social recommendations startup that was eventually acquired by Yahoo, providing him with a firsthand understanding of the high-pressure environment of the startup world. Following that, he spent five years in the upper echelons of Instagram’s product organization. During his tenure at the social media platform, he played a pivotal role in scaling some of the most recognizable consumer features in modern history, including Stories, Feed, Direct Messaging, and Reels.

Before his return to Google in 2024, Stein served as the head of product at Artifact, an AI-powered newsfeed that gained significant attention for its sophisticated approach to algorithmic content delivery. This diverse background—ranging from founding a startup to leading massive, mature platforms—makes him uniquely qualified to address the "scale divide." For those currently managing the transition from an early-stage product to a platform with mass-market reach, Stein’s experience offers a rare look at how the same product principles can be applied effectively in both environments.

Navigating the New Era of AI Search

Today, Stein’s work is squarely focused on the future of information retrieval: generative AI products within Google Search. This role places him at the epicenter of one of the most significant technological shifts in decades. The scale of this transition is staggering. In May 2026, Google reported that its AI-powered search features had surpassed 1 billion monthly users, reaching this milestone just one year after its initial introduction.

This massive adoption is not just a statistical victory; it represents a fundamental change in how users interact with the web. Earlier this year, Stein shared updates to the search experience that allow users to transition seamlessly from a static AI Overview into a dynamic, follow-up conversation. This design reflects a sophisticated understanding of modern user behavior, catering to those who want quick, definitive answers while also accommodating those who wish to engage in deeper, more exploratory research.

This work provides a timely backdrop for the questions he will address at Disrupt. For founders attempting to integrate AI into their own products, the lesson is clear: the technology is only half the battle. The true challenge—and the true opportunity—lies in how that technology is framed and delivered to the user. Stein’s session will invite attendees to look beyond the "what" of artificial intelligence and focus on the "how" of the human experience.

Join the Conversation at Disrupt 2026

The questions surrounding growth and scale are universal. Whether a company is a pre-seed startup attempting to find its first product-market fit or a mid-stage organization looking to scale its operations to reach a wider audience, the process of examining one’s own decision-making is essential.

TechCrunch Disrupt 2026 offers more than just a stage for keynote speakers; it is an environment designed for collaboration and networking. With over 250 speakers and more than 200 sessions, the event provides a comprehensive look at the current state of technology. Attendees will have the opportunity to engage with peers and industry leaders across six dedicated stages, participate in roundtable discussions, and explore the latest innovations in the Expo Hall and the Startup Battlefield.

For those planning to attend, there is a limited window to secure tickets at a reduced rate. Prospective attendees can save up to $200 on their passes by registering before September 25 at 11:59 p.m. PT. Additionally, for teams and groups of four or more, there is a further opportunity to save 30% on tickets, making it an accessible event for entire startup teams to learn, network, and refine their product strategies.

As the industry continues to evolve, the ability to build, adapt, and scale remains the defining characteristic of successful companies. By attending this session at Disrupt, participants can gain a better understanding of how to bridge the gap between their current stage and the massive impact they aspire to achieve. Ensuring that a product’s approach to building evolves alongside its user base is not just an operational necessity—it is a strategic imperative for the future of any technology-driven business. Securing a pass now ensures that you are part of the conversation at the forefront of the industry’s next big shift.
