About
Ciro is a San Francisco-based AI prospect list building platform — backed by Y Combinator — providing B2B sales teams with AI-powered prospecting that builds targeted prospect lists in under 5 minutes by combining hundreds of vertical-specific web crawlers with a proprietary data ingestion engine that aggregates dozens of public and proprietary data sources. Bootstrapped to $1.5 million in annual revenue in 2024 with a 30-person team, Ciro focuses on giving sales teams fast, accurate prospect lists for their specific vertical (local business targeting, industry-specific searches, technology stack filtering) without the manual list-building that consumes SDR time that could be spent on outreach.
