Best fractional CAIOs: firms and solo practitioners
A fractional Chief AI Officer decides what a company does with AI and makes sure the money spent on it returns something. For a founder-led company between $1M and $50M, that usually starts with a survey of how staff already use AI tools, a short policy on data and risk, and two or three use cases ranked by hours saved and cost to build. From there the role picks vendors, oversees automation work, trains the team and reports results to the CEO. Most engagements run 1 to 4 days a month. This is a young role and most firms publish no rates; the few published retainers run about $1,750 to $12,000 a month, and fixed-fee AI audits of two to four weeks run roughly $3,000 to $10,000. Providers on this page include solo practitioners, consultancies with a CAIO tier and fractional CTOs who added AI work, so read each row for who does the hands-on building.
