Neomium · 2022–2026

A controller, a battery,
and a cargo drone.

My second founder chapter: high-performance electrification hardware for light electric vehicles and aviation, from the CÆSIUM® Cs-40 motor controller to a magnetic battery architecture and Paratrone, a heavy-lift, energy-efficient cargo drone.

Why Neomium

Neomium was built on a simple conviction: electrification needs better components, more repairable systems, and hardware that actually reaches the field. It also gave us an unusual starting point: some of my co-founders came from paraglider propulsion, and that background set us on the path to our most visionary project, a paraglider-based cargo drone. Between 2022 and 2026 we turned those ideas into real products, funded by public innovation programs and built by a small, serious engineering team.

Founding & team

I co-founded Neomium in October 2022 and led it as CEO, with Marius Meißner as CTO and Roxana Scur as CFO, alongside Sina Straußberger and Jürgen Städtler. From five founders it grew into a team of eleven, spanning power electronics, embedded systems, robotics and physics.

My half was the familiar one: funding and grant strategy, positioning and narrative, operations, partnerships and go-to-market. We were backed by ESA BIC Bavaria, the DBU Green Startup program and the Bavarian HAMI program.

What we built

Three product lines, one powertrain vision.

CÆSIUM® Cs-40 at AERO Friedrichshafen 2025

01 · CÆSIUM® Cs-40 · the one that shipped

The Cs-40 was our first product to reach the market: a 40 kW (54 hp) motor controller built for the awkward gap between e-bikes and cars, the world of light electric vehicles, along with small electric aircraft, boats and large drones. It runs up to 200 V on hand-picked Infineon power electronics and a custom cooling design, on top of the open-source VESC® platform. It launched and was first sold in early 2025, premiering at AERO Friedrichshafen. Read the AERO 2025 launch →

02 · the battery Magnetic Cell Cluster · MCC®

Our battery work centered on a more repairable, circular approach we called the Magnetic Cell Cluster (MCC®): a weld-less architecture with magnetically contacted cells, single-cell monitoring and replaceability, and real second-life potential. The patent-pending architecture predated my involvement; my part was organisational rather than technical, helping drive its optimisation by leading and supporting the engineering team, with the core technical direction under our CTO, Marius Meißner.

Patent published as WO2025162845.

03 · Paratrone · the moonshot

Paratrone was the ambitious one: an autonomous, paraglider-based cargo drone for heavy, energy-efficient aerial logistics, designed to carry up to 500 kg while using roughly 85% less energy than a combustion helicopter. We demonstrated a working proof of concept in 2025, and it was the project behind much of our public funding.

Patent published as WO2025252462.

Builder culture · Rall-E

Not everything was a flagship. When a ride-on mower died, we brought it back fully electric on our own controller and battery tech and called it Rall-E. It's the clearest picture of Neomium's culture: serious hardware capability, with a sense of humour. Read the Rall-E build →

The handover

Leaving Neomium was one of the harder decisions I've made. By early 2026 the company had its technical and organisational foundation in place, and I chose to hand leadership to the founding team and step into a different chapter.

I'm proud of what we built together, grateful to the people who built it, and genuinely optimistic about where they take it next.

"Neomium was a second chance to turn a conviction about hardware into products people can actually buy, this time with a real team alongside me."
