CTO Hours Calculator
Find out how many technical leadership hours your business actually needs. See if a fractional CTO makes sense for you.
Direct answer
Estimate how much technical leadership your startup needs each month.
The CTO Hours Calculator estimates monthly technical leadership needs based on company stage, developer team size, technical complexity, and whether a tech lead already exists. Lower results suggest occasional advisory support, mid-range results fit fractional CTO work, and higher results may justify part-time or full-time leadership.
Use the result to decide whether you need architecture review, roadmap support, vendor oversight, or help preparing a production deployment plan before investing in more development capacity.
