JONATHAN GRIZOU // FRACTIONAL R&D LEAD

Your product needs a scientist.

You don't have one, and you don't need a full-time hire. I work alongside your team a few hours a week.

//No pitch. You will leave knowing where to start.

The hard part of your product isn't engineering

Your team can build. The trouble is knowing what to build, which approach will hold, which paper won't replicate, which impressive demo breaks on real data. Those calls need someone who has spent years judging this field, and nobody in-house has.

Get it wrong and you find out two quarters and half a runway later.

Sometimes the right answer is a clever use of an existing API. Sometimes it's original research. I care about which one is true for you, not about building something complicated. What I won't do is guess.

A few hours a week is enough

We meet weekly

We look at what happened, decide what matters next, and set a goal your team can hit before we meet again. Progress comes from the cadence, not from long workshops.

I work between sessions

Analysing data, reviewing literature, testing an approach. You get judgement that has had a week to form rather than an opinion produced on the spot.

Your team does the building

I am not a bottleneck and I don’t hold the keys. Every decision gets explained, so the reasoning stays with your engineers after I leave.

A few days with your team and your data, then a costed plan: what to prioritise, what it would take, and what it would cost. Enough to make a decision.
