Welcome to Adidacta, the P/MF Detective Agency.
Every startup is a case. Let's solve yours.
How would you like to start?
Hi, I'm Adi Shmorak. Fractional CPO in Jerusalem.
Product/Market Fit is a case you can solve.
I help early-stage founders find P/MF by working backwards from the evidence: who it's for, why they'd care, what to build, and how it pays.
P/MF Sanity Check: your P/MF strategy, reworked in 2 hours. $499. Running a fund or accelerator? Buy them for your founders.
“Adi is the best CPO I've met. He is super strategic, a fast thinker and simply gets it.”
Founders and teams I've worked with
The method: four variables, in order
- ICP: who it's for.
- Value proposition: why they should care.
- Product: how you keep the promise.
- 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.

All 74 testimonials5.0 from 47 founder reviews on GrowthMentor
“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.”
“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.”
“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.”
“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!”
“He has a unique ability to re-frame/clarify our thoughts and explain his 'product/market fit' expertise in a practical and applied way.”
“He puts out hypotheses, not solid “facts” and makes you test them with the market.”

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.
