Investors back AI security, trust, cloud efficiency, and web data

Across this cluster, investors are pouring capital into infrastructure meant to make AI safer, cheaper, and more reliable. JetScale AI raised a $5.4M seed round to cut cloud compute costs and their climate impact, while Nimble secured $47M Series B to provide live, verifiable web data to AI systems. On the security side, NODA AI closed a $25M Series A for its defense-focused AI platform, Israeli cyber startup Gambit Security raised $61M, and t54 Labs landed a $5M seed to build a “trust layer” that governs AI agents. Together, these rounds signal strong conviction that the next competitive edge in AI will come from secure, trusted agents running on efficient infrastructure with high-quality, real-time data.
