Sound familiar?
You don't need a full-time CTO to solve these problems.
Most founders and agency owners face the same questions. Answers take experience — not a full-time salary.
?
Which stack should we start with — and will it still fit tomorrow?
?
We posted the job, but how do we pick the right engineer?
?
Architecture lives only in a founder's head — undocumented.
?
Our vendor says "everything is fine" — is it really?
?
What must not be skipped when moving from MVP to scale?
?
An investor asked for technical due diligence — what do we ship?
?
The dev team grew but velocity dropped — why?
?
Costs exploded (cloud + tools) — how do we optimise?
