## Overview

Causo flips traditional prospecting on its head. Rather than subscribing to a static contact database and filtering it with dropdowns, you tell Causo in plain English who you want to reach — for example, "Series A and B SaaS firms selling into financial services on AWS" — and its research agents go hunting across websites, filings, registries, trade directories and job postings. Each company comes back researched, with a match score and the sources behind every claim.

Beyond company discovery, Causo identifies and verifies the right decision-maker at each account. It cross-references team pages, press mentions and public records, runs address and SMTP checks on candidate emails, and marks contacts as verified before they reach your campaign. That evidence layer is what separates it from generic list-building tools.

The final piece is outreach. Causo drafts emails that reference the specific findings it uncovered about each company, so messages read as researched rather than templated, and you can edit any draft before it sends. An MCP connector lets you drive the whole workflow from an AI assistant such as Claude, and the platform supports CSV export for teams who want to work from their own systems.

## Pricing & Plans
