Your ideal customers don't always fit into database filters. Describe what you're looking for in plain English, and Causo investigates public sources to find companies worth pursuing, with evidence behind each match. Dig deeper in Causo's chat or run the same research in ChatGPT and Claude through MCP. Once you know who fits and why, Causo helps find decision-makers, verify their emails, and write outreach grounded in that research. Better GTM intelligence. Less slop.
Sales databases are great at telling you a company's industry and headcount. They're much worse at the question that matters: does this business actually have the problem you solve?
So we built Causo around the research. Describe your ideal customer, however specific. Causo investigates public sources, finds companies that might fit, and shows the evidence behind each match. Keep asking questions in chat, or use the same research inside ChatGPT and Claude through MCP.
We call it Palantir for GTM: connecting scattered public information into a reason to approach someone. Contact details and emails come after that, once you have something worth saying.
What's the most awkwardly specific ICP you've tried to find? Drop it in the comments.
Database filters are where good lists go to die, so I like the angle. The MCP bit is nice too, means I don't have to move my whole stack. How do you keep the research from drifting at volume?
nice to see the evidence right next to each match, that's what I'd check first. does it show how old a source is, like a news piece from two years ago?
I took the Causo MCP for a drive a few weeks ago and can confirm it's fire.
Think "highly personalized outreach emails to hard-to-find people without ever leaving your agent UI."
The raccoon in the subject line as a reply driver made me smile 🦝 Since Causo also verifies emails and writes the sequences, do you check the sender domain's SPF/DKIM/DMARC before people start sending, or is that left to their own stack ??
The farm planning-permission example makes this much easier to understand. That sort of evidence gives a rep something concrete to check before reaching out.
Where you've been before guys?! This product is a must-have for every startup, selling b2b products. Costs a tiny fraction of what it takes to hire another part-time sales person, while bringing leads & conversations... It's a no-brainer for gaining early traction, imho.
Do you use your product to sell itself?
And btw can you disclose what's the average reply / conversion rate from those emails?
Hey PH, this is Dawid, one of the two Causo raccoons!
You know how getting a new job or even commenting on someone's linkedin post these days means you immediately get 50 cold emails saying "I saw you did this. Do you want to buy from me?"
It's the main driver behind people saying outbound is dead. A big chunk of the signals layer is commodified - noticing someone's announcement or public activity no longer moves the needle.
Great GTM engineers know that custom buying signals are the real gold: the industry specific, tough to find combinations of facts that help you understand if your prospect really has the pains your product solves.
Causo is your incredibly smart GTM engineering partner. Give it a complex ICP or a specific niche, and it helps you find fitting companies and decision-makers with a mix of custom buying signals. Then, Causo helps you do deep research on companies: like enrichment, but on steroids. Pull out details of tech stacks, company histories, market changes - it's like having military grade intelligence on your prospects.
Causo works with frontier research APIs and powerful raccoon technology to let you work with any data source online, so you can save money on subscriptions. Plug Causo into your Claude or ChatGPT, and have it directly power your GTM stack.
We've developed with version of Causo in tandem with early stage startup accelerators and deep tech companies - who have use of the most specific and tough to find signals out there.
Patent registries, industrial databases, scientific journals, reviews and places data - those are just some of the sources you get with Causo.
Cannot wait to see what GTM plays you build with Causo!! 🦝🦝🦝
