Fractional Head of Product vs. a Full-Time Hire
Both get you senior product leadership. One costs a fraction of the other and starts next week. Here's when each actually makes sense.
Not sure? Let's talk →The Quick Answer
One question settles most of this. Is there forty hours a week of work that only a senior product person can do, and can you describe the profile well enough to interview for it? If yes, hire full-time. If not, a fractional Head of Product gives you the same ownership at ten to twenty hours a week, starting in weeks rather than months, on a monthly retainer rather than an employment contract.
When to Choose Each
- You need product leadership in weeks, not the 3-6 months a senior full-time search usually takes
- You're not ready for a $150k-250k+ full-time salary and equity commitment
- You want to test what "good" product leadership actually looks like before hiring permanently
- Your product needs are real but not yet a full-time job - 10-20h/week is enough
- Your product organization is large enough to need daily, full-time leadership
- You need someone embedded in company culture and politics long-term
- You've already validated what the role needs to look like and are ready to hire against it
- Budget and headcount are approved and the search timeline works for you
Which One Are You Actually Looking At?
Founders frame this as a budget question. It is a scope question.
- You are still writing tickets between fundraising calls
- Your PM runs a sprint well and has never owned a roadmap
- Nobody can name the metric the last three releases were meant to move
- You have rewritten the job spec twice and still cannot describe the profile
- You need someone in the standups in three weeks, not in six months
- More than one product team, each needing weekly one-to-ones and career conversations
- The job is as much hiring and managing PMs as it is doing product
- Product decisions need someone in the room every day, not on agreed days
- You have seen good product leadership in this company and can describe it
- Budget and headcount are approved and the search timeline works
What Actually Differs
Ownership, not availability
Fractional is not advisory with a better title, and it is not a discount on a salary. Aleksander embeds ten to twenty hours a week as the actual Head of Product: owning the roadmap, running discovery, leading standups and reviews, making the calls. A full-time hire buys the same ownership plus the other twenty hours, which go into presence, line management and company politics.
Weeks to start, not months
A senior product search usually runs three to six months, then a notice period. A fractional engagement starts within a week or two of the scoping call, opens with a two-week audit of what has shipped and what is still a guess, and typically runs six to twelve months. It is a retainer with an independent contractor, not an employment contract.
A function that runs without them, or a permanent hire
A full-time hire leaves you with a person on the org chart. A fractional engagement is judged on what survives without them: a roadmap tied to business goals, discovery and delivery running in parallel rather than as a relay, coached PMs and designers, and the rituals written down. When you are ready to hire, the same person shapes the spec and the interview process.
What Fractional Ownership Looked Like at Taxfix
Taxfix is Germany's leading mobile tax app, with more than a million users. Aleksander joined the Activation team as a fractional Senior Product Manager, reporting to its Product Director.
Two products, one front door
Taxfix sells two things: file your German tax return yourself, or hand it to a certified tax expert. The onboarding was built when self-serve was the only option, so everyone landed in the same flow. Marketing was about to buy users with assisted intent at scale in Q1, into a funnel that never showed them what the ad promised.
Eight concepts, cut to three, shipped in the peak
The concepts were mapped along a spectrum of perceived assistance: early value propositions, a try-it-now start, delaying the choice until after the first task, recommending a product from the profile, starting inside an expert chat. Eight in all, across new users and returning customers. The plan of four live by peak did not survive contact with capacity, so it was cut to three, mobile first.
Guardrails, and a concept switched off
Activation conversion, booking conversion and product regret were named as guardrails before anything shipped. One concept lifted expert-product selection and quietly hurt overall booking and activation, so it was switched off and reworked rather than shipped. A "What's new" re-onboarding proved harmless to the core metrics and became permanent. Full sequence in the Taxfix case study.
Where This Decision Goes Wrong
Both mistakes are expensive, and only one of them is obvious at the time.
