Arcos raises €5.5m seed to build and operate civil security infrastructure in Europe
High-Tech Gründerfonds leads a €5.5m seed for the Munich company linking sensor signal processing to the control room that acts on it.
Arcos, a Munich company founded in 2025, announced a €5.5 million seed round on 18 September 2026. High-Tech Gründerfonds (HTGF) led, joined by Bayern Kapital, Pact, Haufe, Robin Capital and strategic business angels. The company was founded by Louis Wübben and Moritz Steigerwald, both of whom hold the title of founder and managing director.
The product is integrated civil security infrastructure rather than a sensor or a piece of software on its own. Arcos processes signals from connected sensors, centralises the decision on what each signal means, and runs the resulting incident through detection, assessment, escalation and documentation to resolution. The sites it addresses run from homes and commercial properties through to railway stations, electrical substations, data centres and airports.
The framing in the announcement is sabotage and physical threats to infrastructure, not consumer alarm systems. “We combine signal processing and the operational process in one system,” said Steigerwald, who added that daily operations then show immediately where workflows need to improve. “Protecting critical infrastructure is a central task of our time,” said Sebastian Borek of HTGF.
Proceeds go to expanding the team in Germany, extending the platform, and preparing to scale into the critical infrastructure market and further European markets. The cap table is worth reading as a signal in itself: HTGF and Bayern Kapital are both publicly backed German seed investors, and the round closes a company that operates infrastructure as a service rather than shipping hardware, a business model that German seed capital has historically been slow to underwrite.
Why it matters for AgTech founders: farms are distributed critical infrastructure and have the same unsolved problem. Grain stores, biogas plants, irrigation pumps, remote sensor networks and machinery with five-figure GPS units all sit unattended for most of the day, and the sector's answer has mostly been to sell more telemetry. The reason that has not converted is the gap Arcos priced: an alert with nobody on the other end is not a product, it is a notification. What is being funded here is ownership of the response loop, and that is where the recurring revenue and the switching costs live. The second lesson is the framing. Resilience opens balance sheets and public co-investment that efficiency does not, and ag founders working on biosecurity, water security or supply-chain traceability should test whether their product reads as a resilience purchase rather than a cost-saving one before their next raise.
