Scalestack raises early VC round led by Leonis to govern enterprise AI agents

What's the deal? Scalestack has raised a new early-stage round led by Leonis Capital, with participation from Zapier, Deel, and AAF. The New York startup also acquired Alysio, an AI agent workspace, to build a governance and control layer between enterprise agents, the models they use, and the systems they act on.

What does Scalestack do? It operates a secure platform to scale autonomous AI agents inside enterprise software like CRMs, applicant tracking systems, and ERPs. The platform controls what each agent can read, change, and spend, and leaves a record of every action.

By the numbers: Scalestack says it handles more than 6 million records a quarter for dozens of enterprises. Inside Typeform, it turns over 400,000 form submissions a month into usable context at more than 90% accuracy. At recruiter Hueman, it cut candidate screening from nine days to same-day decisions.

What's the endgame? Enterprise software was built for people, but agents are becoming its primary users. Scalestack is positioning itself as the "dispatch desk" that gives each agent the right context, enforces company rules, and logs what it changed and what it cost.

In their words: "No enterprise will hand that work to a model it doesn't control," said co-founder and chief executive officer Elio Narciso. "With Leonis, strong corporate partners, and the Alysio acquisition, we can get there faster."

The signal: Investors are pouring money into controlling what AI agents can do — reporting tallied $435 million across 12 agent-security and governance financings between April and September 2026, and Sentra disclosed a $150 million round in November. Scalestack's funding and acquisition terms are undisclosed, so its scale is hard to compare, but Zapier and Deel's participation signals strategic demand for a trusted layer between agents and corporate systems.
