Scalestack Raises New Funding Led by Leonis Capital, Acquires Alysio to Build the Autonomous Infrastructure for Enterprise Agents

Also backed by Deel and other corporate partners, Scalestack gives enterprises trusted context and full control over what their agents can access, change and spend.

NEW YORK, Nov. 10, 2026 /PRNewswire/ -- Scalestack, the secure platform to scale autonomous AI agents, today announced new funding led by Leonis Capital, with participation from Zapier, Deel and AAF, and its acquisition of Alysio, an AI agent workspace. Together, the funding and the acquisition expand Scalestack into the governance and control layer between agents, the models they use and the systems they act on.

Enterprise software was built for people. Agents are fast becoming its primary users, reading records, changing systems and making decisions inside CRMs, applicant tracking systems, ERPs and data warehouses. Most enterprises are not set up for that yet, and every company will need a secure layer between its agents and the systems they act on. Without it, companies cannot say what their agents read, change, cost or return, and so agents stay on a short leash: prompted, supervised and inherently manual.

Scalestack is that layer. Think of it as the dispatch desk for agent work: every agent picks up its task with the right context, works within the company's rules, and leaves a record of what it did, what it changed and what it cost. Underneath, Scalestack moves data in and out of every system, turns it and the company's business logic into context agents can trust, and controls what every agent may read, write and spend, whichever model or tool it runs in.

Governing agents comes down to three things: what they know, which rules they follow, and what they are allowed to change. Scalestack already handles all three in production, across 6M+ records a quarter for dozens of enterprises.

Inside Typeform's product, it turns more than 400 thousands form submissions a month into trusted context at over 90% accuracy, so every agent that acts on a response starts from complete information. At DigitalOcean, it applies the company's territory rules before anything is written back to Salesforce, the same check an agent needs before it touches a system of record. Hueman rebuilt candidate screening on Scalestack, so agents judge each applicant against hiring policy inside an agentic workflow that sets their limits and records every decision, cutting the time to a decision from nine days to the same day. At Clio, Scalestack is the orchestration and guardrail layer between its data lake, data vendors, agentic research and Salesforce. Clio's business logic lives in Scalestack, and nothing is written back to the system of record without clearing Scalestack's gate. Clio has built more than 30 autonomous workflows on it. Attento, Scalestack's agent that builds and runs governed workflows from a plain-English description, has become what Clio's team calls their "agents' favorite agent."

"I say often that the form is only the beginning. Typeform is turning every response into a workflow that AI can act on right away. Before Scalestack, it was really hard to turn answers and emails into trusted context about who sent it. Now we can, in seconds, autonomously, and across millions of submissions, and that is what lets our customers' workflows act on it." - Aleks Bass, CPTO, Typeform

"Soon, most of the work inside any enterprise will be done by agents and, over time, no enterprise will hand that work to a model it doesn't control. Companies will own the context and the rules their agents run on, and every action will be checked, governed and recorded, whichever model comes next. That is the layer we are building, and our customers already run on it. With Leonis, strong corporate partners, and the Alysio acquisition, we can get there faster." - Elio Narciso, Co-founder and CEO, Scalestack

Leonis Capital, a research-driven AI fund whose partners include former OpenAI researchers, and whose backers include researchers and executives from Anthropic and Nvidia, led the round. Deel, the global HR and payroll platform, and Zapier, the leader in automation and orchestration, joined as strategic investors.

Scalestack already supplies the context and business rules enterprise agents run on. Alysio adds the workspace where agents execute, so the same layer that tells an agent what is true can also govern what it does. The acquisition accelerates Scalestack's governance roadmap forward.

"As AI agents move from answering questions to taking actions, the bottleneck is shifting from model intelligence to enterprise trust and control. Every company will need a way to give agents the right context, enforce business rules and govern their actions across systems. We believe Scalestack is building a foundational layer of this new enterprise architecture, and its traction with major customers gives us conviction that this shift is already underway." - Jay Zhao, Managing Partner, Leonis Capital

"Agents are only as good as the data underneath them. Scalestack's ability to turn high-volume raw data into actionable context pairs naturally with the workflows our customers run on Zapier. We're glad to back them." - Wade Foster, Co-founder and CEO, Zapier

The funding will grow Scalestack's engineering and go-to-market teams and accelerate the next stage of its platform: a gateway that governs every request, from any agent, harness or model, by each enterprise's own rules, and an orchestration layer for autonomous, always-on, durable agents that run both in the cloud and locally.
