The diagnosis

If growth stalled, product strategy is usually why.

Three patterns show up in nearly every Series A and B product org I walk into. They are structural, not industry specific.

Chaotic priorities

Hard working teams shipping the wrong features. No explicit link between the roadmap and revenue.

Churn you cannot explain

Competitors move faster and the product struggles to hold users across the lifecycle.

Misalignment

Sales promises one thing, engineering builds another, and marketing is unsure what to say to whom.

A fractional CPO gives a Series A or B SaaS company senior product leadership one or two days a week, at roughly 70% less than a $300K full-time hire. Sivan Kadosh is an independent fractional CPO for B2B SaaS, embedding part-time to own product strategy, roadmap and prioritization at $8,000 for 25 hours a month. I run the product function inside your team, and I stay on the hook for the number.

Collaboration models

Model Best when What I own Cost
Strategic Product Advisory The strategy needs settling before you add headcount or spend. The product narrative, the bets, and the board facing story. From $5,000 a month
Fractional CPO Partner Most common You are scaling and the CEO is still the de facto head of product. Roadmap tradeoffs, prioritization, PM coaching, the weekly cadence. $8,000 for 25 hours a monthFour month minimum
Interim CPO A leadership seat is empty and the roadmap cannot stall while you hire. The product function end to end, plus the search and the handover. $8,000 for 25 hours a monthFour month minimum

“I publish my pricing because hiding it wastes everyone’s time. A founder should know in thirty seconds whether an engagement fits the budget, before they ever book a call.”

How I work

Diagnose, align, execute, and stay on the hook.

01 / Strategy

Data driven diagnosis

Market, competition and usage data, read properly. A roadmap tied to ARR, LTV and payback.

02 / Execution

Inside the team

I run the product rituals, mentor your PMs, and put in lean agile that ships faster without losing quality.

03 / Results

Accountable outcomes

We set the KPI targets together, and I stay on the hook for them: churn down, conversion up, CSAT up.

FAQ

Questions founders ask first.

More detail lives on the full FAQ page.

What is the ROI versus a full-time CPO hire?
A full-time CPO costs $250K to $350K plus equity and takes months to hire. I provide the same executive level judgment immediately, focused on the high impact levers: strategy, process and alignment. You get the seniority without the ramp up or the severance exposure.
How quickly can you affect churn and the roadmap?
I start by stopping the wrong work. Month one is diagnosis and realigning the roadmap to revenue goals. Measurable movement on churn usually takes three to six months because it is a lagging indicator, but the clarity and velocity shift is visible inside the first 30 days.
We have a Lead PM. Will you step on their toes?
No, I mentor them. Strong PMs are often excellent at execution but have not yet had to do board level strategy or scale complex systems. I partner with them on strategic thinking while I handle the high stakes organizational alignment.
Is this hands on execution or high level advisory?
Series A and B companies need action, not slides. I review PRDs, refine the backlog, interview customers and establish the agile rituals. I do not just tell you what to do, I help build the machine that does it.
You do not know our niche. Can you still help?
You have the domain expertise, I have the product scaling expertise. The problems at Series A and B (churn, chaotic roadmaps, a disconnect between sales and engineering) are structural, not industry specific. I help you monetize your niche knowledge by building the right product engine around it.
How much of my time will this take as CEO?
The goal is to give you time back, not take it. After kickoff and alignment I operate autonomously with your product and engineering leads. We hold a weekly sync to track KPIs, and I am not another direct report to manage.
What happens when we are ready for a full-time CPO?
That is often the end goal. When you reach the scale where a full-time CPO makes sense, I help write the scorecard, interview candidates and run a clean handover to your permanent leader.
