The problem

Most founders don't lose to bad products.
They lose to bad timing.

Talking to the right buyer six months too early — they're polite, they're curious, they ghost. Six months too late — someone else already sold them. There's a small window when a B2B company is actively shopping. We catch it.

TELL 01

They just raised.

A funding round means budget is unlocked and growth pressure is real. The buying team becomes findable for the first time.

TELL 02

They just hired the role.

The first VP People, founding AE, or Head of Growth is hired specifically to solve a problem. Yours might be it.

TELL 03

They just shipped at scale.

The thing they launched is now breaking at the new volume. They're shopping for tooling — and they don't have it yet.
