Studio
A software venture studio,
built around senior engineering.
Yam Labs builds and operates its own software, takes equity and operating roles in ventures, and partners on a small number of high-value client engagements each year.
Three modes, one standard.
Yam Labs operates across three interlocking modes. We build and run our own software products. We take equity and operating roles in early ventures — typically as a founding technical partner. And we take on a small number of client engagements each year, where the fit is right and the work is genuinely interesting.
The hybrid model exists for a reason: operating real software in production keeps the engineering honest. There is no gap between the advice and the practice. When we build for clients, we bring the same standards we hold ourselves to — because we live with those standards in our own products every day.
The result is a studio with genuine skin in the game — not a consultancy that moves on to the next engagement. Client work sharpens the craft. Our own products prove it.
You work with the engineer, not a layer above them.
By design, Yam Labs stays small. You work directly with the principal who does the engineering — no account managers, no handoffs, no juniors learning on your budget.
Senior, focused, and accountable. That’s the model — and it’s not incidental to the quality; it’s the source of it.
Lukas May
Founder, Yam Labs · Co-Founder & CTO, Carealytix
Lukas founded Yam Labs in Munich in 2021. As CTO of Carealytix Digital Health GmbH he leads the engineering behind Mizu — a Class I medical device used by 10,000+ patients — owning architecture, delivery, and the quality processes a regulated product demands.
Before Carealytix, he worked through Toptal’s top-global-talent network and spent six years in Java development and PLM consulting at DSC Software AG. He studied Engineering & Management at the Karlsruhe Institute of Technology (KIT).
Senior-only, no layers.
Every engagement is handled by the principal. There is no team behind the scenes waiting to be introduced; there are no project managers translating between you and the engineer.
We operate what we build.
Yam Labs runs its own software in production. The judgment we bring to client work is grounded in operating real products — not theoretical best practice.
Selective by design.
We take on a handful of engagements at a time. That constraint is intentional: depth and quality are impossible at volume.
Correct, operable, maintainable — over speed theatre.
We build software that the next engineer can understand, operate, and extend. Shortcuts that look like velocity today become debt that slows teams for years.
Mizu
Mizu is a companion app for people living with chronic kidney disease — a Class I medical device used by 10,000+ patients across early-stage CKD, dialysis, and transplant. It is built and operated by Carealytix Digital Health GmbH, where Yam Labs’ founder serves as CTO, owning architecture and engineering from day one. Developed under ISO 13485 and 27001 quality and security processes; GDPR-compliant and EU-hosted. In market since 2021.
A small studio.
Serious work.
We work with founders and operators who know what they’re building and want a technical partner who operates — not just advises. If the fit is right, we move fast.
