NewCore, a stealth‑mode cybersecurity startup, closed a $66 million seed round on Monday, elevating its valuation to $300 million. The round was led by Cyberstarts, with participation from Index Ventures and Evolution Equity Partners.

The company is building an identity platform that treats human employees, machines, and AI agents as first‑class identities. While existing providers such as Okta and Microsoft’s Entra are beginning to add AI‑agent support, NewCore’s founders argue those additions are merely side‑bars to platforms originally designed for people.

"The rise of AI agents convinced me that current identity systems are ill‑suited for a future where software workers operate alongside people," said co‑founder and CEO Zohar Alon, who previously founded Dome9 before its acquisition by Check Point. He warned that the scale and complexity of AI agents would break 15‑ to 20‑year‑old identity platforms.

Alon launched NewCore with CTO Amihai Neiderman, a former Unit 8200 research leader who founded the healthcare AI startup Nym Health, and CCO Erez Yarkoni, who served as CIO of T‑Mobile USA and Telstra.

NewCore’s platform uses a "split‑key" architecture that divides critical identity credentials between the customer and the platform, eliminating a single point of compromise. The company also offers an "Agentic Skill" integration package that lets coding assistants such as Anthropic’s Claude Code, OpenAI’s Codex and Cursor access enterprise systems as managed identities rather than through manually distributed credentials.

Employees can use NewCore’s mobile app to grant, review and revoke access for AI agents, providing a human oversight layer as companies deploy more autonomous systems.

The startup has more than 50 employees across the United States and Israel. According to the company, it has fewer than 10 customers and more than 10 design partners, and it plans to begin charging customers in the summer.

Alon noted that AI agents are already being treated as workplace participants. Goldman Sachs tested an AI coding agent called Devin as a new employee last year, and McKinsey reported that 25,000 AI agents work alongside its 60,000 employees. He predicts that AI agents could outnumber human employees at many technology‑focused organizations within a few years, a view echoed by TCS Chairman N. Chandrasekaran.

"Identity is likely to become one of the first enterprise systems strained by large‑scale deployment of AI agents," Alon said. "Companies will eventually need new ways to monitor, authorize and revoke software workers operating across their networks."

The funding round comes at a time when enterprises are expanding the use of generative AI and autonomous agents. With the growing number of AI agents in corporate environments, the need for secure, scalable identity governance is becoming a priority.

NewCore’s launch adds a new option for organizations that want a platform built from the ground up to manage human, machine and AI identities together. The company’s focus on a split‑key architecture and integrated oversight tools distinguishes it from legacy identity providers that are adding AI‑agent support as an add‑on.

As AI agents become more common, the industry will likely see further investment and product development aimed at securing these new digital workers. The next few months will reveal whether NewCore’s approach gains traction in the market and how it competes with established identity vendors.

In summary, NewCore has secured $66 million to develop an identity platform that treats AI agents as first‑class identities. The company’s split‑key architecture and integrated oversight tools aim to address the security challenges posed by the growing use of autonomous AI workers in enterprises.
