Estimate the all-in cost of a fractional CTO vs a full-time hire — including SR&ED tax recovery. Free, no email required.
Canada (CAD) United States (USD)

Estimate the all-in Canadian-dollar cost of a fractional CTO versus a full-time hire — including SR&ED tax recovery, the part most cost comparisons miss. A Canadian-controlled private corporation can recover up to 35% of qualifying R&D, and the technical lead a fractional CTO fills is exactly who the CRA interviews. Free, no email required — these are estimates, not tax advice.

A fractional CTO and a developer — for less than one full-time CTO

At a startup or SMB, a full-time CTO often spends roughly 80% of their time on hands-on development and only 20% on strategy — CTO pay for work a developer can do. For less than that single salary, a fractional CTO can own strategy and architecture while a dedicated full-stack developer ships the roadmap: the right person on each job, not one expensive generalist stretched across both.
