In short

Sivan Kadosh is a solo fractional Chief Product Officer for B2B SaaS companies at Series A and Series B. With 18+ years leading products as a CEO and CPO, he embeds part-time to own product strategy and roadmap. His work has lifted net revenue retention from 102% to 112% at a $30M ARR SaaS.

Whether founders call it a part-time head of product, an interim product leader, a fractional CPO, or product leadership on retainer, the engagement is the same: a senior product operator embedded in your team, accountable for the outcome.

Why founders come to me

I have seen both endings, from the inside.

Both endings

Exits and failures, in the seat

I have operated in companies that scaled hard, the kind that end in exits worth hundreds of millions, and in companies that failed. Watching both up close is what makes a product’s path legible.

Scar tissue

Scars you never have to earn

Pricing calls that backfired, roadmaps that looked right and were not, teams scaled a quarter too early. I stop founders from making the mistakes that cost millions.

Hands dirty

Not one discipline

Engineering, product, data, and the willingness to get my hands dirty in any of them. If the answer is buried in the data, I will pull it myself.

How engagements work

Scope agreed up front, pricing published in full.

Engagement

25 hrs a month

The standard engagement. 3 month minimum, then month to month. Every figure is published in full on the pricing page.

Scope

Strategy, roadmap, PM coaching

Embedded in your team, on a monthly retainer.

Availability

Start in 2 to 3 weeks

A small number of engagements at a time.

Fit

When I am, and am not, the right fit.

I take on a small number of engagements, so I am direct about where another choice would serve you better. Not a fit yourself but know a founder who is? The referral terms are here.

✓A good fit when

✓You are Series A or B and product decisions still route through the founder.
✓You have engineers shipping but no senior product leader owning strategy.
✓You want someone accountable inside the team, not a deck from the outside.

×Not a fit when

×You need a full-time CPO in the building five days a week.
×You are pre-revenue or still searching for product-market fit.
×You are looking for UX or UI design production rather than product leadership.

Questions

Frequently asked questions

The price is published in full on the pricing page: the seat at 25 hours a month with a three month minimum, or a scoped day with no minimum. Either way it is a fraction of the $250,000+ all-in cost, plus equity, of a full-time CPO.

A consultant advises from the outside and hands you a recommendation. As a fractional CPO I embed in your team, own product strategy and roadmap decisions, coach your PMs and stay accountable for the outcomes. The difference is ownership, not just advice.

The right time is usually Series A or B, when product has become the bottleneck but a full-time CPO is premature. If the founder still makes every product call, the roadmap is a list of requests, or growth has stalled despite shipping, that is the signal. Hiring a full-time CPO can take up to eight months (Sifted, 11 August 2023), which is why fractional exists.

I work solo. You get me directly as your embedded product leader. I coach your existing product and engineering people rather than bringing a separate agency team.
