Riveter AI logo

Riveter AI

Thousands of AI search agents running in parallel

Riveter is bringing the power of Perplexity to the scale of the spreadsheet. Their AI agents, custom scrapers, and integrations pack the power of browser use and automation for search, at a cost that allows for scale. Most teams still spend hours (or hire UpWorkers/contractors) to manually copy product specs, check competitor pricing, pull custom KYB/KYC data to assess customer risk, or scrape filings. Perplexity and ChatGPT are great for single questions, but they can’t handle large amounts of data at once. And they’re working with a single agent and context window instead of one in every cell. And Riveter’s web browsing can go further—even reading PDFs and images that may contain answers. With Riveter, anyone can automate complex, auditable web research… without coding. Our founding team brings deep product and engineering expertise from to YC-backed companies Gusto, Retool, and Middesk.
