Tech Startups (VC Funding Roundup, July 16)·medium signal

Beacon Security raised a $13M seed led by Notable Capital, positioning itself as a platform for agentic cybersecurity work with 300% ARR growth in the first half of 2026. It joins the wave of AI-native security startups eating manual security-ops and compliance workflows (the Snyk/Wiz/Vanta adjacency). Fast ARR growth off a seed round signals real pull for agents that execute security tasks rather than just surface alerts.
