Promenade Software vs Spyrosoft: overview
Promenade Software
Promenade Software was founded in 2013 and is headquartered in Irvine, California with a small team, most recently reported around 11 employees. The firm's advisory value centers on applying web-framework development speed to embedded medical device software while holding to FDA-relevant safety-critical requirements, a specific architectural tension most general firmware consultants haven't solved for. Its CyberMed·Cloud product line adds a dedicated medical device cybersecurity advisory angle beyond general architecture consulting.
Spyrosoft
Spyrosoft was founded in 2016 and is headquartered in Wrocław, Poland, listed on the Warsaw Stock Exchange as Spyrosoft S.A. with 2,253 employees worldwide as of December 2025, roughly 81% concentrated in Poland. The company's embedded software engineering advisory sits within a broad services portfolio spanning enterprise software, AI/ML, cloud, cybersecurity, and user interfaces, and its own published technical guides on IEC 61508 and ISO 26262 functional safety indicate genuine in-house standards expertise, not just a listed service line. For an advisory buyer prioritizing enterprise-scale public-company backing above narrow firmware specialization, Spyrosoft is the largest publicly traded option on this list by headcount.
