San Francisco: Scalekit, a startup built by the team behind Freshworks’ authentication system, today announced the launch of its authentication stack designed for AI agents, alongside a $5.5 million seed funding round.
The round was led by Together Fund and Z47, with participation from angel investors Adam Frankl, Oliver Jay, Jagadeesh Kunda, and others.
Scalekit introduces purpose-built authentication for AI agents
Scalekit provides a developer toolkit that enables secure identity management and tool-calling for AI agents. Unlike traditional systems, which assumed humans logged into applications, Scalekit addresses a future where autonomous AI agents interact with business apps and APIs.

Gartner has predicted that by 2028, 25% of enterprise breaches will involve compromised AI agents, underscoring the urgency of such infrastructure.
Co-founder and CEO Satya Devarakonda said, “Scalekit sits at the intersection of verifying every agent’s identity and enforcing precise, least-privilege access through a single drop-in toolkit.”
Authentication Stack Features
Scalekit secures both incoming authentication for MCP servers and outgoing agent actions to third-party tools. Key features include:
- A turnkey OAuth 2.1 authorization server for MCP servers.
- Encrypted token vaults and a tool-calling layer for agent workflows.
- Short-lived scoped tokens for agent identities embedded in code.
- Modular authentication for human users, including passwordless login, OTP, single sign-on, and machine-to-machine service tokens.

Adoption across AI-native companies
Several AI-native companies and SaaS applications have already adopted the stack for their authentication needs. Early users include Fello, Sifthub, Napkin, Unstract, Hubbl, and Aerchain.
SiftHub’s Head of Technology, Harsh Vakharia, stated, “We needed auth that just works so we could focus on our core AI features. Scalekit eliminated months of auth complexity and let us ship in a couple of weeks.”
Fello’s CTO, Suman Varanasi, added, “We plugged in Scalekit’s passwordless auth module without any refactoring. That lego-style flexibility got us live in two weeks.”
Roadmap for agent identity
The company plans to strengthen its agent-centric identity offerings with new capabilities such as background agent support, deeper tool-calling integration, granular authentication logs, and prebuilt connectors for over 1,000 external applications.
Girish Mathrubootham, Founding Partner at Together Fund, commented, “Scalekit spotted the shift early and built the missing agent identity infrastructure. We believe that foundation will power the next billion agent identities.”
