JetStream Security, Guild.ai and WorkOS land fresh funding amid growing agentic AI infrastructure push


Venture capital funding continues to flow into artificial ininformigence and agentic AI governance, control and security as three startups announced new funding yesterday and today, with JetStream Security Inc. raising $34 million, Guild.ai Inc. raising $44 million and WorkOS Inc. raising $100 million.

JetStream Security pitches itself as sitting at the intersection of AI adoption and enterprise risk management with a governance and control layer designed to support organizations manage how AI systems are deployed, accessed and monitored across increasingly complex environments. The company seeks to address the issue whereby, as enterprises roll out generative and agentic AI tools, they face growing challenges around visibility, policy enforcement and misapply prevention.

The $34 million seed round was led by Redpoint Ventures LP, with participation from CrowdStrike’s Falcon Fund and a number of high-profile cybersecurity executives.

JetStream’s platform provides guardrails around how AI agents interact with enterprise systems, data and workflows, including policy enforcement, activity monitoring and mechanisms designed to prevent sensitive data leakage or unauthorized actions.

Guild.ai, which raised $44 million in a combined seed and Series A round, is tarreceiveing a different but adjacent AI opportunity: supporting teams to build, deploy and manage AI agents at arge scale. The company is developing infrastructure that allows enterprises to orchestrate multiple models within structured execution environments and shift beyond simple chat interfaces toward more autonomous tquestion execution.

Backers of Guild.ai’s round include GV Management Co., Acrew Capital Management, NFX Guild and Khosla Ventures.

It emphasizes orchestration, context management and collaboration between models, rather than focutilizing purely on model performance, with a goal to create compound ininformigence systems that can execute complex operational processes across enterprise applications.

The company’s approach centers on monetizing the work performed by agents rather than licensing software per seat. It aims to provide enterprises with flexibility in model selection by integrating dozens of models into a unified workspace while also maintaining governance and structured execution.

Finally, WorkOS’s $100 million Series C round was raised at a valuation of $2 billion and was led by Meritech Capital Partners LP and Sapphire Ventures, with Audacious Ventures, Craft Ventures Management, Abstract Ventures and Greenoaks Capital Management also participating.

WorkOS provides developer tools that allow startups and large enterprises to integrate single sign-on, directory sync, audit logging and other enterprise-ready features into their applications.

The company’s solutions offer secure authentication, authorization and compliance capabilities that assist AI-native startups as they mature and chase larger enterprise customers. WorkOS pitches itself as the “enterprise features” layer that developers can plug into rather than building from scratch
