Scalekit Launches AI Agent Authentication Stack with $5.5M in Seed Funding

Scalekit today launched its authentication stack designed for AI agents, securing a $5.5 million seed round led by Together Fund and Z47. The company, founded by the team behind Freshworks' authentication system, provides a developer toolkit to manage agent identity and secure API access.

As AI agents increasingly interact with business applications, traditional human-centric security models are becoming obsolete. Gartner predicts that by 2028, 25% of enterprise breaches will involve compromised AI agents. Scalekit addresses this by verifying agent identities and enforcing least-privilege access, preventing the need for developers to build insecure workarounds.

"For years, software focused on blocking bots. Now, business apps must authenticate agents and control their data access," said Satya Devarakonda, Scalekit's co-founder and CEO. "Scalekit provides a single drop-in toolkit to manage this."

Scalekit offers a turnkey OAuth 2.1 authorization server, an encrypted token vault, and a tool-calling layer for popular apps like Gmail, Slack, and HubSpot. This allows developers to securely manage both incoming authentication and outgoing agent actions.

"AI agents are emerging as first-class users of business software, and current identity stacks can't keep up," said Girish Mathrubootham, Founding Partner at Together Fund. "Scalekit has built the missing agent identity infrastructure that will power the next billion agent identities."

Companies like Fello, Sifthub, and Unstract are already using Scalekit to secure their AI-native applications. "Scalekit eliminated months of auth complexity and let us ship in a couple of weeks," noted Harsh Vakharia, head of technology at SiftHub.

With the new funding, Scalekit plans to expand its agent-centric features, including support for background agents, deeper tool-calling capabilities, and pre-built connectors for over 1,000 external applications.
