Quadsat, a standout graduate of our Mission 1 Seraphim Space Accelerator cohort (2018), has now closed a €5 million Series A+ financing, led by Join Capital and North Ventures. Seraphim is proud to remain alongside this forward‑thinking team as a continuing investor in their exciting next phase.
Since joining our accelerator, Quadsat has evolved from early-stage innovators, using UAVs to calibrate satellite antennas, to a mission-critical provider of platform-agnostic spectrum intelligence and RF geolocation solutions. Their cutting-edge technology is now being leveraged across both commercial satellite operations and national defense domains.
This Series A+ round positions Quadsat to:
At Seraphim, we invest in founders building transformative, high-impact tech and Quadsat embodies that vision. From the day they entered the accelerator to today’s strategic growth round, we’ve been honored to support their leadership, technical excellence, and unwavering focus on real-world outcomes.
Congratulations to Joakim Espeland, Klaus Aude, and the full Quadsat team and many thanks to our co-investors (Join Capital, North Ventures, EIFO, and others) for your confidence. We’re excited to continue this journey alongside you as you scale spectrum intelligence across the globe.
