What is Causo?
Find leads beyond database filters with AI research & MCP
Causo is an AI sales-lead research and outbound agent for startup GTM. Instead of filtering static lead databases, you describe your ideal customer in plain English and Causo's research agents scan public sources — websites, job posts, company registries, filings, directories, and news — returning real, verified leads with evidence and sources.
Key capabilities:
- AI lead research — Describe your buyer in plain English; the agent researches public sources and verifies each company with citations.
- Deep-dive with cited Q&A — Follow-up questions about any company are answered with sources attached.
- Decision-maker finding — Finds the right contacts and verifies emails via a data waterfall (Findymail, Apollo, Hunter).
- Research-grounded outreach — Drafts personalized emails and sequences in your voice, sent from your connected mailbox after your review.
- MCP server — https://mcp.causo.ai/mcp works with Claude, ChatGPT, Claude Code, Cursor, and VS Code; no API key or browser login needed.
- Fundraising module — A database of 1,150+ funds, CVCs, and angels for investor outreach.

Common questions
Causo FAQs
Is Causo just another lead database?
No — Causo is not a static lead database. It does real-time research across public sources and shows its evidence for every company, verifies emails, and writes outreach grounded in that research.
Where does Causo's research data come from?
Public sources: company websites, job posts, registries, filings, directories, and news. Every research answer comes with citations so you can check the sources.
How do tokens work?
One completed action costs one token. You start free with 50 one-time tokens, no card required; paid plans add monthly token allowances and one-time top-ups cost $0.30/token.
I don't know my ideal customer profile. Can I still use it?
Just describe what you sell in plain English and Causo helps you define your ideal customer profile — no sales experience needed. It also works for non-tech industries.
How does outbound sending work?
Causo drafts personalized emails and sequences in your voice and sends them from your own connected mailbox only after you review. You choose the recipients — it never sends on its own. No mailbox is needed for the free trial.
