Architecture, how you handle technical debt, and who you hire early all set limits on what you can build later. Those three decisions tend to get made when a team is smallest and least equipped to make them.
Why the timing matters
Early on, almost any reasonable technical choice works. Later, the cost of a wrong call compounds: rework, a team hired in the wrong shape, features you cannot ship because the foundation will not hold them. The decisions that matter most tend to arrive before you have anyone senior enough to make them.
What a fractional CTO actually does
It is a part-time arrangement. Someone senior owns the architecture decisions, sets the technical direction, and speaks for technology at the leadership table. The work is the same work a full-time CTO does. You are buying less of it, at the stage where less of it is all you need.
How we work with you
We embed with your team rather than reporting on it from outside. That means being in the standups, reading the code, and making the calls in the open where your engineers can see the reasoning. As your own team grows into the role, we hand the work back.
