Scalekit raises $5.5M to build authentication stack for AI agents

SaaS startup Scalekit has raised $5.5 million in seed funding to launch its authentication stack tailored for AI agents. The round was led by Together Fund and Z47, with participation from angel investors Adam Frankl, Oliver Jay, and Jagadeesh Kunda.

San Francisco-based Scalekit was founded by the team that previously built Freshworks’ authentication platform. According to the founders, traditional identity systems were designed for human users logging into software, but the rise of AI agents—interacting with business apps and APIs on behalf of users or autonomously poses new security challenges.

Gartner estimates that by 2028, a quarter of enterprise breaches will involve compromised AI agents. Scalekit aims to address this gap with a toolkit that verifies agent identity and enforces least-privilege access. The platform offers short-lived, scoped tokens and plug-in tooling to help developers secure “agentic workflows” without relying on brittle, ad hoc solutions, according to a statement.

“Business apps now need to let authenticated agents in, not just block bots,” said Satya Devarakonda, Co-founder and CEO. “Scalekit sits at the intersection of identity and access, helping developers grant agents only the permissions they need.”

Ravi Madabhushi, Co-founder and CTO, added that the company builds on lessons learned scaling authentication for more than 50,000 businesses at Freshworks: “The next challenge is managing identities that live in code, not user directories.”

“Auth is invisible until it fails. Satya and Ravi bring the experience of scaling it for thousands of enterprises and are now reimagining it for the AI era," Pranay Desai, Managing Director at Z47, said.

“AI agents are becoming first-class users of business software, but current identity stacks can’t keep up. Scalekit is building the missing infrastructure for the next billion agent identities," Girish Mathrubootham, Founding Partner at Together Fund, added.
