Step 01CRM sync

Native sync with every major CRM.

HubSpot, Salesforce, Pipedrive — Pronto pushes verified emails, mobile numbers and full company records straight into your CRM as standard fields and objects. Two-way sync keeps records fresh, deduplicates on contact, and never overwrites what your reps typed in. No CSV exports, no manual paste.

Step 02Outreach & sequencers

Verified contacts, straight into your sequences.

Lemlist, HeyReach, Smartlead, La Growth Machine— the moment Pronto verifies a contact, push it directly into the sequence that's waiting for it. No CSV round-trips, no stale records sitting in your sender, no “why did this bounce?” the morning after.

Step 05MCP server

Talk to your contact data — in plain English.

The Pronto MCP server lets Claude, Cursor, ChatGPT and any agent stack call enrichment as a tool. Ask “find the VP of Sales at every Series-B fintech in NYC and grab their mobiles” — your agent runs the search, enriches, dedupes and hands you a list. Production-grade contact data, agent-native.
