Positioning
Not every technology pain is a role to fill
Different pains, almost always the same answer: hire. Some call for execution, others for direction, and many for both, orchestrated in the right proportion. Getting that framing wrong is expensive.

Backlog growing
Product with no technical direction
Platform that doesn't scale

He asked for a developer. The problem was something else
The conversation about the problem, before we got to the role, turned up a different story: two dev shops along the way, one attempt at an in-house team, and no one among the founders with a software engineering background. The role wasn't the problem. Technical direction was missing.

“Understanding the role is not enough. What we want to understand is the problem behind it, and which capability, in which format, actually solves it. That is why we stay close after the start: through the ramp-up, talking to the company and to the professional, adjusting whatever needs adjusting. Support, end to end.”
