Hey Product Hunt! 👋 I built CNPJ Aberto because looking up Brazilian companies shouldn't require a paid subscription or a terrible government website. Brazil has 55M+ registered companies, and all their data is public by law. But accessing it has always been painful, slow government portals, CAPTCHAs, and limited search. CNPJ Aberto makes this data actually useful: **Instant search** by company name, ID (CNPJ), or partner name **Corporate network graph** — see who owns what and how companies connect **Red flags** — automated risk analysis **Health score** — 0-100 rating based on 7 objective criteria **Control tree** — visualize ownership hierarchy **Batch lookup** — search hundreds of companies at once + lots of other custom tools The free tier gives you 200 lookups/day (no credit card). Pro is $8/month for 5,000/day + advanced tools. Built with Next.js 15, FastAPI, and PostgreSQL with trigram search for instant fuzzy matching across 55M+ records. Would love your feedback!
