Stellar Cyber Inc. — Cyborg Score 7/10

Strategic Profile

Founded in 2015, Stellar Cyber is a Series B company based in Santa Clara. The company's Open-XDR platform helps eliminate tool fatigue and data overload often cited by security analysts. Stellar Cyber has 10 investors including Big Basin Ventures, Northern Light Venture Capital, Valley Capital Partners, and Susquehanna International Group.

Cyborg Score Rationale

Stellar Cyber demonstrates solid market positioning in the growing Open-XDR security operations category with demonstrated product-market fit (MSP Today award in 2025). Recent debt financing (April 2026) and a growing team (146 employees as of May 2026) indicate operational momentum. However, as a Series B company without major institutional backing or public disclosure of revenue metrics, growth velocity and market traction remain partially opaque.
