要点
A fractional professional splits time across multiple organizations — fractional CTO/CFO/CMO roles are common. Unlike one-off consulting projects, fractionals are ongoing leadership with part-time allocation. Operational reality: 3–8 Google accounts and calendars that do not interoperate; Tenbin targets merged free/busy for one booking link across up to 10 accounts.
Definition
A fractional professional dedicates a fraction of their time to each of several organizations — typically with separate Workspace accounts.
Common roles
Examples: fractional CTO 1–2 days/week; fractional CFO; CMO; COO; board advisor hours per month — varies by contract.
Why fractional is growing
Startups need expertise before full-time hires; remote work expanded cross-border arrangements. Market sizing varies by analyst — directionally up since 2022.
Scheduling challenge
Separate Google identities per org → fragmented availability. Traditional scheduling assumes one employer.
FAQ
Consultants are often project-based; fractionals are embedded part-time leadership with recurring cadence.
