Chamelio raises $26M Series A for AI legal agents as ARR quadruples in five months

Chamelio has raised $26 million in Series A funding, just five months after its seed round, as the legal AI startup says annual recurring revenue has quadrupled over that stretch.

The round was led by Entrée Capital, with participation from existing investors Work-Bench and Emerge Ventures. Bright Pixel Capital joined the round. Chamelio said the new capital will fund its legal action model, product and legal engineering teams, and the technology used to move customers off older legal software.

Founded in 2024 by Alex Zilberman, Gal Lellouche, and former general counsel Gil Banyas, Chamelio is building software for in-house legal departments that can draft contracts, review terms, route requests, track obligations, and carry out legal workflows through AI agents.

The pitch targets a problem corporate legal teams know well: more work, limited headcount, and software that often acts more like a filing cabinet than an active legal assistant.

Chamelio says it now has hundreds of customers, including Wiz, monday.com, Socure, AppsFlyer, and Wonderful.ai. Its software connects with systems such as Salesforce, Slack, NetSuite, and procurement tools.

From contract storage to AI agents

Contract lifecycle management software has traditionally focused on storing documents, moving contracts through approval processes, and tracking changes. Chamelio is betting that the next version of legal software will be expected to perform more of the work itself.

Its platform can draft from a company’s existing contracts, review and negotiate language, manage incoming legal requests, track obligations, and run multistep workflows. Companies can allow agents to handle routine work automatically or keep lawyers involved where human review is needed.

“The mistake in legal AI has been assuming the future simply looks like today’s lawyer with faster contractual fact-checking,” said Alex Zilberman, CEO and co-founder of Chamelio. “AI in a legal setting shows dividends when it can make decisions intuitively, built on the corporate intelligence of each individual business. This is what Chamelio does. We ensure in-house legal departments deliver watertight contracts and outputs at AI speed, validated by the rigor of lawyers.”

Chamelio is entering a legal technology market that has become one of the most active areas for enterprise AI adoption. Corporate legal departments face pressure to handle growing workloads without matching increases in staffing or budgets, creating an opening for software that can take over repetitive contract and workflow tasks.

That shift is drawing investors toward companies trying to move legal AI beyond search, summaries, and drafting assistance into systems that can take action across business processes.

“Chamelio is building the AI-native operating system for in-house legal teams – becoming the system of record, system of action, and system of intelligence for the modern legal function,” said Eran Bielski, General Partner at Entrée Capital. “What stood out to us was not only the strength of the product, but how quickly Chamelio’s founders execute, learn from customer feedback, and turn that feedback into a product with category-defining potential.”

The fourfold ARR increase in five months gives Chamelio a stronger signal than funding alone. Legal AI is crowded, and many startups can now generate contracts or answer questions about them. The harder task is becoming part of the daily operating system inside a legal department.

Chamelio is betting that AI agents, rather than another layer of contract software, will be the way it gets there.
