Scalekit raises USD $5.5M to secure AI agents in enterprise IT

AI identity infrastructure firm Scalekit has raised USD $5.5 million in seed funding as it launches a developer toolkit to authenticate the identities and manage the access of autonomous AI agents in enterprise environments.

The investment round was led by Together Fund and Z47, with participation from angel investors Adam Frankl, Oliver Jay, Jagadeesh Kunda, and others. Scalekit's authentication stack is designed in response to the growing prevalence of non-human users, such as AI agents, in business software ecosystems.

Security risk

Analyst firm Gartner has projected that compromised AI agents could account for 25% of all enterprise security breaches globally by 2028, highlighting the increasing pressure on businesses to secure agentic workflows. The use of traditional identity systems, which primarily authenticate human users through browsers and manual interactions, is no longer sufficient as AI agents engage with business applications autonomously or on behalf of human users.

Satya Devarakonda, Co-founder and Chief Executive Officer of Scalekit, underlined the challenge facing software teams adapting to this new reality.

"For years, software focused on blocking bots. Now business apps must let authenticated agents in and decide exactly what data they can read or write," says Satya Devarakonda, co-founder and CEO. "Scalekit sits at that intersection of verifying every agent's identity and enforcing precise, least-privilege access through a single drop-in toolkit."

The company's stack enables businesses to authenticate AI agents in scenarios where conventional identity systems are ineffective, including instances when agents generate short-lived sessions and interact with hundreds of different applications across a technology stack.

Investor perspective

Girish Mathrubootham, Founding Partner at Together Fund, commented on the investment and Scalekit's approach to the market.

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

Scalekit's solution provides both incoming authentication for Model Context Protocol (MCP) servers and manages outgoing agent actions to third-party tools. Teams using Scalekit are able to quickly integrate an OAuth 2.1 authorisation server, encrypt tokens, and build tool-calling functions for agents to interact with common business applications such as Gmail, Slack, HubSpot, and Notion.

Technical response

Ravi Madabhushi, Co-founder and Chief Technology Officer of Scalekit, discussed the technical background behind the development of the authentication stack.

"After scaling auth for 50,000 businesses at Freshworks, we saw the next challenge coming: agent identities that live in code, not in user directories. Scalekit delivers short-lived scoped tokens and plug-in tooling that make agentic workflows secure."

Beyond agent identity, Scalekit also addresses needs on the human user side, providing modular authentication features such as email-based magic links, two-factor authentication, single sign-on, and machine-to-machine service tokens designed for rapid deployment.

Pranay Desai, Managing Director at Z47, emphasised the platform's modular approach.

"Scalekit lets developers adopt only what they need with no forklift migration required. That modular model, paired with lightweight implementation, is why teams building agentic workflows are standardizing on Scalekit," says Pranay Desai, Managing Director, Z47.

Early adopters

Organisations already utilising Scalekit's authentication services include Fello, Sifthub, Napkin, Unstract, Hubbl, and Aerchain, where agentic features are essential for business activity.

Harsh Vakharia, head of technology at SiftHub, said, "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."

Suman Varanasi, CTO at Fello, added, "We plugged in Scalekit's passwordless auth module without any refactoring. That lego-style flexibility got us live in two weeks."

Roadmap

Scalekit's product roadmap includes expansion of agent-centric features such as background agent support, deeper integrations for tool-calling, enhanced authentication logging, and ready-to-integrate connectors for over 1,000 external applications. The company will continue to develop tooling to accommodate the increasing sophistication and range of AI agent use within enterprise IT environments.
