German Startup Pulse: SE3 Labs Eyes Defense, Personio Faces Heat, Grenion Collapses

Germany's defense tech scene gets a new contender in SE3 Labs, HR giant Personio is under mounting pressure, and D2C scaleup Grenion Group — parent of HelloBody — files for insolvency. Here's what's moving in the German startup ecosystem.

SE3 Labs: Germany's Next DefenseTech Bet

SE3 Labs is emerging as one of Germany's most closely watched defense technology startups. The company is positioning itself in a sector that has seen a dramatic surge in investor interest across Europe, driven by shifting geopolitical realities and increased defense spending.

Germany's DefenseTech ecosystem has been maturing rapidly, with SE3 Labs joining a growing cohort of startups aiming to modernize military and security infrastructure through software and hardware innovation.

Personio Under Pressure

Personio, once a flagship of the German B2B SaaS scene, is facing intensifying scrutiny. The Munich-based HR software company — valued at over $8 billion at its peak — is reportedly navigating internal and market challenges that have put its growth trajectory under the microscope.

The pressure on Personio reflects broader headwinds hitting enterprise HR software providers as customers tighten procurement budgets and demand faster ROI from their software investments.

Grenion Group Slides Into Insolvency

The Grenion Group, parent company of popular direct-to-consumer (D2C) brands including HelloBody, has filed for insolvency. The development marks a significant blow to Germany's D2C segment, which boomed during the pandemic before facing brutal margin compression and rising customer acquisition costs.

Key facts about the collapse:

HelloBody was among Grenion's most recognized consumer brands
The group followed a D2C scaleup model heavily reliant on performance marketing
Rising ad costs and post-pandemic demand normalization contributed to the pressure
Insolvency proceedings are now underway

Grenion's fall is a cautionary tale for D2C brands that scaled aggressively on paid social without diversifying revenue channels or building sustainable unit economics.
