B2B PROSPECTINGLive

Protocolo SDR

B2B prospecting on the official CNPJ registry, with AI-written outreach.

PROBLEM

Purchased lead lists arrive stale, with no filter for size or activity, and the outreach is identical for everyone — which guarantees a low reply rate and a burned number.

WHAT I BUILT

Queries the official public CNPJ registry with filters for activity code, company size, region and registration status, enriches contact data, and generates AI-personalized outreach per company, delivered over WhatsApp at a controlled cadence.

RESULT

A prospecting pipeline that goes from a generic list to a queue of genuinely eligible companies, with the first message already written in each business's context.

WHAT IT DOES

  • Official CNPJ registry with activity and size filters
  • Contact enrichment
  • AI-generated outreach, company by company
  • Paced WhatsApp delivery
