Enterprise AI governance startup Arcade has raised $60 million in a Series A round led by SYN Ventures, following a $12 million seed earlier in 2025. The company helps organizations define and enforce which actions AI agents are authorized to perform.
The funding underscores a growing demand for guardrails as companies deploy increasingly autonomous software. Arcade aims to solve a core challenge: giving AI agents enough freedom to be useful while preventing costly or dangerous missteps.
Arcade previously raised a $12 million seed round in 2025. The Series A was led by SYN Ventures, a firm focused on cybersecurity and enterprise software.
The company now faces a crowded field of AI governance startups, including competitors like Guardrails AI and WhyLabs. Arcade differentiates itself by focusing specifically on agent authorization rather than broader model monitoring.
Separately, Radical Numerics, an AI research lab for biological data, raised a $50 million seed round led by Emergence Capital, CEO Eric Nguyen confirmed. The company is developing AI models that learn directly from biological data, bypassing traditional feature engineering.
