AI funding boom: HappyRobot raises $150M, Zenity $125M as agent startups surge
AI agent startups just raised $400M+ in days—here's who got funded
The AI funding landscape in early August 2026 is dominated by a single theme: AI agents. HappyRobot raised a massive $150M Series C to automate enterprise operations with AI agents, while Zenity secured $125M led by Norwest Venture to help enterprises control and secure agent deployments. Onyx Security followed with $113M to give enterprises visibility and governance over AI agent behavior. These mega-rounds signal that investors see agent infrastructure as the next critical enterprise layer, not just a novelty.
Mid-stage and seed rounds are also heating up. Sapiom raised $35M Series A to help AI agents reach production reliability, and RWX landed $12M Series A to build infrastructure for AI coding agents. Inevitable AI Group raised $6M led by Aleph. Earlier in the month, Paper raised $34M for design tools in the AI coding era, and Greyparrot snagged $27M for AI-driven waste intelligence. With over $400M flooding into agent-centric startups in a single week, the message is clear: enterprises are moving from experimentation to deployment, and the money is following the tooling, security, and automation layers that make agents dependable at scale.
