Meta PMs Use Vibe Coding to Build Prototype Apps for Mark Zuckerberg

Meta’s product managers aren’t waiting on engineers to turn ideas into demos. Instead, they are vibe coding to design prototype apps themselves and presenting them directly to CEO Mark Zuckerberg.

“PMs are actually vibe coding products, and we’re showing them to Zuck and leadership, and it’s allowing us to iterate and explore the space really fast,” said Joseph Spisak, a product director in Meta’s Superintelligence Labs (MSL), onstage at the TechEquity AI Summit in Sunnyvale, California, on Friday.

Vibe coding, a term originating in developer communities, refers to AI-assisted coding using instructions provided in natural language.

“We can literally vibe code products in a matter of hours, days, and explore the space,” Spisak added.

Spisak described Meta’s “internal systems” as powerful enough for non-engineers to adjust interfaces on the fly, allowing developers to “change colors and change ideas.”

The remarks shed new light on how Meta, like the rest of Silicon Valley, is reorganizing product development around AI assistants. Meta uses at least two: Metamate, a ChatGPT-style bot trained on internal data, and Devmate, a coding assistant that incorporates multiple large language models, including those from rivals like Anthropic, to speed up programming.

Speeding up the development process and embracing vibe coding have become top priorities at MSL, which Meta formed in June as it races against other AI rivals. One memo from late September said that Meta’s existing systems, designed for billions of users and giant engineering teams, take “too long” to deploy changes and are “not conducive to vibe coding,” making it harder for small, fast-moving AI teams to experiment.

Similar transformations are underway across Silicon Valley. Google has spent the past year pushing workers to integrate AI into every stage of product development. Last year, Google CEO Sundar Pichai said that more than a quarter of Google’s code is generated by AI before being reviewed by humans. At Microsoft, executives have told managers that “using AI is no longer optional,” according to an internal memo obtained by Business Insider.

Meta is making similar internal pushes toward AI. The company tracks employees’ AI usage through dashboards, sets adoption targets, and even runs an internal game called Level Up that rewards staff who hit AI milestones, Business Insider reported last month.

Vibe coding skills have also become a recruiting priority across the tech industry. Firms like Reddit and DoorDash now list experience with AI coding tools like Cursor and Bolt as desired skills, according to a Business Insider report, and at least one Y Combinator startup calls vibe coding “non-negotiable” for new hires.

“We are getting to the point where the barriers are really low right now,” Spisak told the audience, adding that even his 11-year-old daughter now vibe codes new environments to play in Roblox

“This is what I tell PMs at Meta and other places where I mentor PMs,” Spisak said. “Don’t be afraid to get your hands dirty.”
