Meta’s product managers are bypassing traditional engineering workflows by using AI-powered “vibe coding” to rapidly prototype apps and present them directly to CEO Mark Zuckerberg. Joseph Spisak, a product director in Meta’s Superintelligence Labs (MSL), revealed this shift during a keynote at the TechEquity AI Summit in Sunnyvale, California, on Friday. “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,” Spisak said. Vibe coding—originally a term from developer circles—refers to creating software using natural language prompts with the help of AI assistants. Spisak emphasized that Meta’s internal tools now empower non-engineers to quickly modify interfaces, tweak designs, and test concepts in hours or days. “We can literally vibe code products in a matter of hours, days, and explore the space,” he said. These tools allow instant changes to colors, layouts, and functionality, enabling rapid experimentation. This transformation is central to Meta’s strategy in its race against AI rivals like OpenAI, Google, and Anthropic. MSL, launched in June, is designed to foster agile, small-team innovation. A late-September memo highlighted that Meta’s legacy systems—built for massive scale and large engineering teams—are too slow and cumbersome for fast-moving AI experimentation, making them ill-suited for vibe coding. To support this shift, Meta has deployed two internal AI assistants: Metamate, a ChatGPT-style bot trained on internal data, and Devmate, a coding assistant that integrates multiple large language models, including those from competitors like Anthropic, to accelerate development. This AI-first approach mirrors broader trends across Silicon Valley. Google has mandated AI integration across all stages of product development, with CEO Sundar Pichai stating that over a quarter of Google’s code is now AI-generated before human review. Microsoft has declared AI use “non-negotiable” for employees, setting adoption targets and tracking usage through internal dashboards. Meta has followed suit, running an internal gamified program called Level Up that rewards teams for hitting AI milestones. The rise of vibe coding has also reshaped hiring. Companies like Reddit and DoorDash now seek candidates with experience in AI coding tools such as Cursor and Bolt. One Y Combinator startup even lists vibe coding as a “non-negotiable” skill for new hires. Spisak noted the democratization of development: “We are getting to the point where the barriers are really low right now,” he said. “Even my 11-year-old daughter now vibe codes new environments to play in Roblox.” He encouraged product managers to take initiative. “Don’t be afraid to get your hands dirty,” he told the audience. “This is the future of product development.”
