# Ciro **Source:** https://geo.sig.ai/brands/ciro **Vertical:** Marketing **Subcategory:** Marketing Automation **Tier:** Emerging **Website:** ciro.io **Last Updated:** 2026-04-14 ## Summary SF YC AI prospect list building in under 5 minutes with vertical web crawlers at $1.5M bootstrapped revenue 2024; 30-person team aggregating public+proprietary data sources competing with ZoomInfo and Apollo for fresher B2B sales prospecting intelligence. ## Company Overview 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. Ciro's AI prospect intelligence platform addresses the data quality and speed limitations of existing B2B sales prospecting tools: large database-based tools (ZoomInfo, Apollo.io) provide broad coverage of known companies and contacts but rely on periodic data refresh cycles that leave months-old accuracy for fast-changing prospect attributes — firmographic data (employee count, revenue) that doesn't reflect recent growth, technology installation data (which CRM or marketing platform a company uses) that lags actual adoption by 3-6 months, and local business contact data that is notoriously inaccurate in generic B2B databases. Ciro's approach (continuous vertical-specific crawling of sources where prospects actually signal their activities — job postings, LinkedIn signals, web technology scanning, business license filings, industry publication mentions) provides fresher data for the specific prospect attributes that sales teams use for qualification: a SaaS company trying to reach businesses that just opened a new location needs real-time new business registration data, not a quarterly database refresh. In 2025, Ciro competes in the sales prospecting, B2B data intelligence, and lead generation market with ZoomInfo (NASDAQ: ZI, $1B revenue, dominant B2B sales intelligence), Apollo.io (sales intelligence and engagement, $100M raised at $1.6B valuation), and Lusha (B2B contact data, $205M raised) for B2B sales team prospect research and list-building platform adoption. The bootstrapped $1.5M ARR with 30 employees at YC backing reflects a capital-efficient team building in a large market. The 30-person data engineering team (relatively large for the revenue stage) reflects the investment in building the crawling and data infrastructure that differentiates Ciro from database resellers. Y Combinator backing connects Ciro with the sales technology investor community. The 2025 strategy focuses on the vertical-specific intelligence use cases (real estate, home services, financial services, and SaaS-selling-to-SMBs), building the intent data layer for identifying in-market signals, and growing the AI-generated outreach personalization using the scraped prospect context. ## Frequently Asked Questions ### What is Ciro?
