Hi, I'm Adi Shmorak. Fractional CPO in Jerusalem.

Your fractional CPO, on the case from day one.

For founders who haven't cracked P/MF yet, with the clock ticking. I join your team part-time, follow the evidence, and keep you on track to P/MF and growth.

I recommend starting with a 2-hour P/MF Sanity Check ($499). You’ll leave with a clear plan for what to do next. If you hire me, I’ll execute it. Running a fund or accelerator? Buy Sanity Checks for your founders.

Why a fractional CPO

Product leadership now, not after the hiring round.

Hiring is hard. You want the best person for the job, but you need to start now. Every week you wait is a week you won’t get back.

A fractional CPO brings their A game, gets up to speed fast, and adds value from day one.

It buys you time, takes the pressure off, and keeps you on track to P/MF and growth.

From $3,000/month, half a day a week to start. See how it works

P/MF = f(Business Model(Product(Value Prop(ICP))))
4 Business ModelHow value comes back to you
3 ProductHow you keep the promise
2 Value PropositionWhy they should care
1 ICPWho it's for
Solve from the inside out. Change an inner variable and everything outside it moves.

The method: four variables, in order

Product/Market Fit is a case you can solve.

  1. ICP: who it's for.
  2. Value proposition: why they should care.
  3. Product: how you keep the promise.
  4. Business model: how value comes back to you.

Most founders start at three. That's why they get stuck. I start at one, collect the clues, and work outwards.

“What helped most is the order. He said 1st is the ICP, then the VP and then finally comes the product which automatically becomes what the customer will pay for.”
S.M.via GrowthMentor
“His detective approach to product/market fit genuinely stands out! He doesn’t just give advice, he helps you think through problems by asking the right questions and validating assumptions step by step.”
Berrin Sevinvia GrowthMentor
“Despite having 800 paying customers, we were struggling to scale, and Adi’s insights into aligning our value proposition with the market were incredibly valuable.”
Pratik Renusevia GrowthMentor
“He asked probing questions, pushed back on some assumptions, and gave a few clear calls to action. It was exactly what I needed to hear!”
David Forervia GrowthMentor
“He has a unique ability to re-frame/clarify our thoughts and explain his 'product/market fit' expertise in a practical and applied way.”
Nick StobbsClient testimonial

Who's the detective?

I grew up reading Sherlock Holmes under the covers. I went into sales, marketing, business development and product, and since 2019 I've been helping founders at MassChallenge and beyond solve their P/MF riddles. I don't hand over a deck and leave. I join you in the trenches.
