Best fractional CTOs: firms and solo practitioners
A fractional CTO is the senior technical judgment a non-technical founder is missing. The typical engagement starts with a review of the code, architecture, hosting bills and the contract with whoever built the product, then becomes a standing seat in product and hiring decisions. Some buyers want a few hours a month of advice; others want two days a week of hands-on leadership over an engineering team or an offshore dev shop. Published fees reflect that spread, from about $3,000 a month for on-call advice to $15,000 a month for an embedded role, and marketplaces quote $100 to $250 an hour. Many fractional CTOs work month-to-month. Watch for the difference between an independent CTO and a development agency that sells a CTO seat to win the build contract; both are listed here, and each profile says which it is. Technical due diligence ahead of a raise or a sale is a common one-off project, and several firms here list it.
