Perplexity’s Build Competition
Perplexity launched 'Billion Dollar Build,' an eight-week challenge that asks teams to build companies with no pitch deck required and offers up to $1 million in investment or credits for finalists. (x.com). The format flips the usual early-stage funnel toward product-first validation and could reshape how founders demonstrate traction to investors. (x.com)
Perplexity is trying to fund startups with an eight-week build sprint instead of the usual slide deck parade, and the prize pool goes up to $1 million in investment or product credits for finalists. The company said teams can apply without a pitch deck, which is a direct break from the standard accelerator script. (x.com) The format is simple on purpose: build something people want, show the evidence, and let the product do the talking. Perplexity framed the challenge around company creation rather than demo-day storytelling, with the program branded “Billion Dollar Build.” (x.com) That lands in a startup market where founders usually spend weeks making slides before they have weeks of user behavior to show. Y Combinator, the best-known startup accelerator, still centers its batches on a fixed program ending in Demo Day, where founders pitch investors in a compressed window. (ycombinator.com) Perplexity is not entering this from the sidelines. The company has spent 2025 and 2026 pushing deeper into tools for builders, including an Agent Application Programming Interface, a Search Application Programming Interface, a Sandbox for isolated code execution, and “Computer,” its browser agent product. (perplexity.ai, perplexity.ai, perplexity.ai, perplexity.ai) So the contest is also a funnel for Perplexity’s own platform. If finalists take the prize in credits, they are effectively getting paid to build on Perplexity’s tools, the same way cloud providers have long used credits to lock early startups into their stack. (x.com, perplexity.ai) The timing fits a company that has been scaling fast and spending like it expects to be infrastructure, not just an app. Perplexity announced a Series B round in January 2024 after reaching 10 million monthly active users, and TechCrunch reported in March 2025 that the company was in talks to raise up to $1 billion at an $18 billion valuation. (perplexity.ai, techcrunch.com) What changes here is the proof founders are asked to bring. A deck is a promise about a future business, but an eight-week sprint can produce working software, user retention, revenue screenshots, or at least a product people can touch, which gives investors a different kind of filter. (x.com, ycombinator.com) That does not mean pitch decks disappear. It means one more investor-backed company is betting that, in an artificial intelligence boom where prototypes can be built in days, the scarce thing is no longer presentation polish but evidence that strangers will actually use what you made.
