When the product is stuck.
Embedded systems
Electronics, firmware, connectivity, signal processing — from a weak signal to a reliable decision.
Y
Intervention CTO · Complex systems
Complexity Clarity
We absorb the complexity.
You keep only what matters.
Fractional CTO and outsourced technical director for the products, architectures and industrial projects that have stopped moving forward.
01 Why Y exists
A problem no one can solve
always has a simple form.
You just have to find it.
The difficulty isn't drawing the line.
It's knowing where to draw it.
-
Understand
Getting beneath the symptoms to the real constraint. The one everyone has worked around.
-
Connect
Linking domains that don't talk to each other. Signal, mechanics, software, regulation.
-
Build
A solution with the means available. Not the ones that are missing.
-
Deliver
All the way to industrialisation. A realistic execution path, not an intention.
02 What Y does
Five moments when you call Y.
When the architecture no longer holds.
Product architecture
From constraint to system. Structural decisions that hold over time.
When the prototype has to become a product.
Industrialisation
From design to production. Compliance, quality, manufacturing — with no break between the prototype and the real world.
When innovation has to become an asset.
Innovation
Fresh technical angles. Building technology assets. Defensible intellectual property.
When you need technical leadership without hiring a CTO.
Intervention CTO
Fractional technical leadership. Long enough to unblock the situation and chart a realistic trajectory.
Experience earned in demanding environments: Oil & Gas, defence, industry and MedTech.
Y works mainly on complex systems, industrial products, embedded systems and SportTech.
03 Working with Y
Three ways to step in.
Blocker diagnosis
Identifying the constraint that truly governs the system. You leave with a clear reading and a realistic next step.
Intervention technical leadership
Fractional CTO. Unblock, arbitrate, hold the trajectory — for as long as it takes, without hiring.
Industrialisation & assets
Taking the solution through to production. Or turning it into proprietary technology, transferable to industry.
04 How Y thinks
Years of thinking.
An obvious solution.
The reasoning disappears. The solution remains.
05 Proof
Solutions are sometimes
born elsewhere.
Three blockers cleared by importing a method from a seemingly unrelated field.
Extreme physics Biomedical signal
The sensors drowned the biological signal in ambient noise. No satisfactory electronic solution.
The signal pulled from the noise, using weak-signal detection methods borrowed from extreme physics — built into the device's regulatory design from the start.
Role — algorithm & design
Cochlear anatomy Connected auscultation
Electronic filtering increased cost, fragility and the regulatory justification burden.
A biomimetic 3D-printed auscultation head — purely mechanical amplification and filtering, with no electronic component. Industrialised through to production.
Role — design & industrialisation
Isometric mapping Field inspection
3 000 faulty valves to inspect. Conventional method: 2 to 4 a day. An untenable timeline.
Isometric geolocation, GPS altitude and augmented reality on a tablet. 20 to 30 valves a day. A ×10 ratio.
Role — design & deployment
06 About
Cyrille Lecroq.
Engineer.
Twenty years at the intersection of embedded systems, software, signal processing and industrialisation. Oil & Gas, defence, industry, MedTech. Founder of several companies. Inventor. Y is the practice he founded and leads.
The value isn't in any single technology: it's in the ability to identify what truly blocks a system — and to resolve it. He steps in when others are stuck.
Inventor: distinguishing the real problem, subjecting it to a systemic analysis that often links distant fields, drawing an innovation from it — then converting it into intellectual property and a product. The SKOP illustrates this: a connected 3D-printed stethoscope for remote auscultation, where the anatomy of the ear translated into purely mechanical amplification, embedded electronics and medical-device regulation all converge — carried through to a product and its regulatory path via WeMed, which Cyrille founded.
