Maximilian Gravemeyer

Founder of Rosenthaler · leading projects, shaping products, and writing the code that ships them since 2018.

Rosenthaler We design, build, and run digital products for established companies.

Rosenthaler is where my work happens. Behind it are 8+ years of shipping across e‑commerce, SaaS, and industrial systems, most of them spent in the room where product decisions are made, not just in the codebase.

Product

In from the first idea: concept, UX, and the creative decisions that make a product work.

Leadership

Engineering

Full-stack and hands-on: web, mobile, AI tooling, and industrial systems.
