The gap

Most teams scale outbound before they know which segment buys.

A thesis about who buys is not evidence. Until it is tested against real buyers, every list, every message, and every month of runway is a bet on a segment nobody has validated.

Who it is for

Founders and early revenue teams who have not yet proven which segment converts.

The ICP is inherited

It comes from founder instinct and a competitor's customer list, not from buyers who replied.

One segment at a time

A single list that goes quiet tells you nothing about which other segment would have answered.

Runway spent guessing

Months of sending pass before anyone can say whether the segment was ever viable.

The solution

We test your thesis against real buyers, segment by segment.

Signal runs before volume. We take what you know about your product and the thesis you built it on, run outbound across several ICPs at once, and let replies decide which segments work and which do not.

Step 01

Take your thesis

We work through your product, the buyers you believe in, and the reasoning behind the thesis you built the company on.

Step 02

Build the candidate ICPs

That thesis becomes several distinct segments, each sized by accounts, contactable buyers, and geography.

Sized on reachable buyers, not total market.

Step 03

Run outbound on each

Every segment gets live outbound in small volumes, with message variants per ICP. Replies, not opinions, separate them.

Step 04

Go or no-go

Each segment gets a written decision. The ones that clear the bar move to Force. The rest are cut.
