ROLES

Fractional CTO

A senior technology executive working 1 to 3 days a week for your company, on a defined scope, without the equity or the full-time salary.

The market for fractional CTOs exists because hiring a full-time one too early is expensive and hiring one too late is fatal. A fractional CTO bridges the gap: they make the architecture calls, run the hiring loop for senior engineers, sit in on board meetings, and write the technical sections of investor decks.

What they do not do, usually, is write production code. If your team needs a strong individual contributor, you want a senior engineer with a CTO sounding-board, not a fractional CTO doing the engineering themselves. We sometimes blur this line at Wavect when the team is small enough that the CTO must still ship; the SoW makes the boundary explicit.

Watch for vendors selling “fractional CTO” as a renamed account-manager role. A real fractional CTO has decision authority, attends the same meetings a full-time one would, and is named in your board materials.

Market rate is roughly 1,500 to 3,500 EUR per day in DACH, billed against a retainer or an SoW. Wavect’s Fractional Co-Founder model is flatter and simpler at 400 EUR per week. The cheapest fractional CTO is almost always too junior; the most expensive is often a rebranded account manager. Check decision authority before checking the rate card.
When you need someone to write production code full-time, when your team has zero senior engineers to back-fill execution, or when your founder is not ready to share architecture decisions. In those cases you want a senior engineer, a tech lead, or therapy, not a fractional CTO.
Three tests: they are named in your board materials, they make architecture calls without escalating to a sales rep, and they will tell you ’no’ on a feature without checking with their agency. If any of those fail, you bought account management with a CTO sticker.
