Asymptote Labs Raises $5.5 Million Seed Round To Build Runtime Infrastructure For AI Agents

WHAT HAPPENED

Asymptote Labs raised $5.5 million in an oversubscribed seed funding round. Tower Research Ventures led the round, with participation from Lytical Ventures, 1984 Ventures, and South Park Commons. The company was founded by Justin D'Souza and Shukan Shah, both former early engineers at social engineering defense company Doppel.

WHAT THE COMPANY DOES

Asymptote builds runtime infrastructure for enterprise AI agents operating across employee workstations, cloud environments, and business workflows. At the core is Beacon, an MIT-licensed open-source telemetry layer that captures activity across Claude Code, Codex, Cursor, and more than 20 additional agent harnesses, normalizing that activity into a common runtime data model. The enterprise platform adds real-time detection, response, and governance capabilities to intercept live agent activity and apply policy-driven guardrails at both the prompt and tool levels.

WHO INVESTED

Tower Research Ventures led the round. Additional investors include Lytical Ventures, 1984 Ventures, and South Park Commons. Angel investors include Doppel co-founders Kevin Tian and Rahul Madduluri and Socket founder Feross Aboukhadijeh.

WHAT THE MONEY IS FOR

Asymptote plans to use the funding to expand engineering and product development, hire additional staff, and increase go-to-market efforts.

WHY IT MATTERS

As AI agent adoption expands across enterprises, security and engineering teams need visibility and control over agents that can access sensitive data and modify systems. Beacon has already gained significant developer adoption since launching in May 2026, with GitHub stars increasing more than 460 percent in September and reaching number three among GitHub's global trending repositories. Asymptote's detection library can identify data leakage, insider threats, AI supply chain risks, and inefficient workflows, with security teams at regulated enterprises already among its early adopters.

THE DEAL

Asymptote raised $5.5 million in the seed funding round.

How it compares
