A fractional CPO gives a Series A or B SaaS company senior product leadership one or two days a week, at roughly 60% less than a $250K+ all-in 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 20 to 25 hours a month in 2026. I run the product function inside your team, and I stay on the hook for the number.
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.
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.
01
Chaotic priorities
Hard working teams shipping the wrong features. No explicit link between the roadmap and revenue.
02
Churn you cannot explain
Competitors move faster and the product struggles to hold users across the lifecycle.
03
Misalignment
Sales promises one thing, engineering builds another, and marketing is unsure what to say to whom.
Collaboration models
Never gatedTwo ways to work together, priced in public.
Every figure here is public, and I publish the market’s verified pricing data behind it in the Fractional Rates Index.
Most common
Offer one
$8,000/mo
20 to 25 hours a month. 3 month minimum.
You are scaling and the CEO is still the de facto head of product.
Roadmap tradeoffs, prioritization, PM coaching, the weekly cadence.
Offer two
$15,000/mo
3 to 4 days a week. 3 month minimum.
A leadership seat is empty, or the quarter demands more than part-time ownership.
The product function end to end. If the seat becomes permanent, the search and the handover too.
The alternative: Full-time CPO, all in
$250K to $350K
The in-house hire this replaces. Plus equity, and months to hire.
“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.
Step 01
Data driven diagnosis
Market, competition and usage data, read properly. A roadmap tied to ARR, LTV and payback.
Step 02
Inside the team
I run the product rituals, mentor your PMs, and put in lean agile that ships faster without losing quality.
Step 03
Accountable outcomes
We set the KPI targets together, and I stay on the hook for them: churn down, conversion up, CSAT up.
The proof
Measured outcomes, not projections.
Every figure is from shipped work, measured against the company’s own baseline. Names are withheld under NDA where required, and references are available on request.

Read all 18 references“Sivan is an excellent product manager, product leader and team member. He cares passionately about delighting customers and is highly capable at all levels from strategic direction to writing detailed documents. I would recommend him 10/10 to any company.”
“Sivan is an excellent product manager and I wholeheartedly recommend him. He has created value in a variety of ways, from top-down vision, mission and goal work alongside the senior leadership team, to taking on complex business analysis and wireframing tasks.”
“As part of his role as VP Product, he identified creative ideas, developed sharp strategies and built the road map while focusing on customer experience and business needs.”
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.
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.
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.
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 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.
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.
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.
