Framing a new B2B offer in six weeks

A strong commercial hunch, and no certainty about the product to build behind it.

01.The challenge

Rule out fast rather than draw fast

The point was not to draw fast, but to rule out fast the leads that did not hold. Six weeks to turn a hunch into a defensible scope, then four months to ship it.

We interviewed buyers directly, prototyped three concepts and dropped two of them in a week, to reach the end of the six weeks with a scope the team could defend.

02.The product approach

Turn a commercial hunch into a scope you can defend.

03.The method

Our approach: a criterion to decide with, not an arbiter.

001.
An audience nobody had asked
B2B buyers had never been asked directly, only through the sales force.
002.
A scope that kept growing
Every meeting added a feature. We needed a criterion to decide with, not an arbiter.
003.
A team to leave self-sufficient
The framing was worth nothing if the internal team could not then hold the roadmap alone.

The roadmap and the components were handed over to the in-house team, which shipped the next three releases without us. The first client was served in production four months after the opening meeting.
