| Iridius is the compliance-by-design AI platform that enables regulated enterprises to design, build, and operate AI systems that are continuously compliant. In regulated industries, AI isn’t failing because of model capability — it’s failing because it can’t operate within real-world constraints: fragmented systems, complex workflows, and strictregulatory compliance requirements. Instead of treating compliance as a manual process that happens after systems are built, Iridius makes compliance part of how systems run. | $8.6M / Seed / Apr 23, 2026 | ||
