Fractional Co-Founder

Fractional Co-Founder is Wavect’s flagship service and it is exactly what it sounds like. We embed at the level a co-founder would: product strategy, technical architecture, sprint planning, customer calls, board prep. In role terms it is usually a fractional CTPO, product and technology under one neck. We do not show up with a tracked-hours timesheet. We show up with the outcome.

Pricing is 400 EUR per week, cancel any week, no notice, no exit fee. If we do not blow you away, the last week is refunded. We do this because the wrong fit costs both sides too much. A two-week trial that ends cleanly is a better outcome than a six-month contract that limps.

Worked example of when this is the right shape: a non-technical founder has revenue but keeps hiring agencies that build the wrong thing because nobody on the inside can challenge the brief. A fractional co-founder sits between them and the builders, owns the roadmap, makes the architecture calls, and tells the founder when the feature they are emotionally attached to is the wrong bet. That posture, owner not contractor, is the entire difference from a fractional CTO, which covers technology authority but does not carry the product and ownership weight.

The Austrian legal nuance: this is engaged as a freier Dienstvertrag, not a Werkvertrag, because we owe ongoing judgement and availability rather than one fixed deliverable, and unlike a real co-founder there is no equity grant or cap-table entry by default. The honest trade-off, and where founders get it wrong: this is not a body to grind tickets (hire a contractor for that) and it is not a substitute for the founder’s own conviction. If you need someone to sit on a hard architecture decision with you at 11pm on a Sunday under a clear SoW, this is the shape of engagement you want. Past PMF and looking for a CTO instead?
