Agent swarms that make long-running tasks exponentially faster

Acyclic builds the infrastructure for agent swarms: open-source primitives for running agents in parallel, and a managed agents platform that runs swarms for you. Complex, long-running tasks are split across many agents, each working in its own instant fork of the workspace, and finish in a fraction of the time.

We built Acyclic because we believe there are huge gains to be had in how agents are run, beyond the models themselves. Agents can already do real work, but they still do it one step at a time, so complex tasks take hours or days. Running them as swarms is an infrastructure problem: isolating each agent, dividing the work, and merging the results without conflicts. Today, teams use Acyclic to run heavy document-processing pipelines in minutes instead of hours.

At Cambridge, we researched ML and auto-parallelising compilers, and then we built multi-agent systems in production: Ram as a Palantir FDE for pharma clients, shipping systems for clinical trial design, and Varun leading agent architecture at Tracelight for Big 4 accounting firms. We kept asking the same question: the agents were good enough, so why couldn't we run thousands of them at once to make everything faster and cheaper? Acyclic is our answer.

Founders

Ram Vinjamuri — Founder/CEO

Ram is a founder of Acyclic Labs. He started in ML research: his Cambridge dissertation on transfer learning for low-resource Vedic Sanskrit beat the state of the art and was published at ACL WiNLP.

At Palantir, he was an FDE shipping multi-agent systems for clinical trial design. That work convinced him there are huge gains in scaling beyond the model. At Acyclic, he is building the infrastructure that lets agent swarms turn complex, long-running tasks from days into hours.

Varun Latthe — Founder/CTO

Co-founder of Acyclic Labs (YC F26).

At Cambridge, my research focused on building an auto-parallel programming language. I then worked on agent architecture and an Excel engine at Tracelight (https://tracelight.ai).

At Acyclic, I’m building infrastructure that extracts implicit parallelism from agent workflows, turning them into efficient swarms for lower cost and latency.
