Virtual CTO Pricing & CTO as a Service: What It Costs

“Fractional CTO”, “virtual CTO” and “CTO as a service” describe the same engagement: senior technology leadership on a part-time, flexible basis. The pricing is identical.

Virtual CTO Pricing

A virtual CTO works remotely with your team — video calls, Slack, and asynchronous reviews instead of office days. Because there is no travel overhead, remote-first engagements are the most cost-efficient way to access CTO-level expertise.

  • •Async advisory from £699/month (Slack-based, 14-day free trial)
  • •Remote retainers from £2,499/month (2 days/month)
  • •Same senior expertise — 5x CTO, 25+ years, successful exit

CTO as a Service Cost

CTO as a service (CTOaaS) packages technology leadership as a subscription: a predictable monthly fee instead of a six-figure salary, equity, and recruitment costs. You scale the commitment up or down as your needs change.

  • •£699–£9,599/month depending on time commitment
  • •Project day rates £800–£1,600/day for due diligence and audits
  • •Pause, upgrade, or cancel with 30 days notice — no lock-in
