How CoCounsel drives legal efficiency and builds trust in AI
A global financial services company leverages CoCounsel to streamline legal workflows, enhance cross-functional collaboration, and ensure data security across its global operations
The Assistant General Counsel (AGC) of AI, IP, and Technology at a global financial services company, has seen firsthand how artificial intelligence is transforming legal work. As the company embraces AI across the enterprise — from product development to internal operations, the legal team has been at the forefront of evaluating and deploying tools that deliver real value.
“We’re embracing AI company-wide,” the AGC explains. “That includes the products we create for the market and using AI throughout all of our entities to make us more efficient and consistent.”

Measuring impact with metrics and collaboration
The company takes a dual approach to measuring AI’s effectiveness. On one hand, they track hard metrics like time to close deals and turnaround speed. On the other hand, they foster collaboration through working groups that share feedback and best practices.
“We measure impact with metrics, of course,” the AGC says. “But we also have a working group where everyone who uses the product shares what they like, tips to make it work better, and how comprehensive or accurate it is.”
This blend of quantitative and qualitative evaluation helps them ensure that AI tools like CoCounsel are not only fast, but also reliable and trusted.
“One reason we chose CoCounsel was because we felt confident that Thomson Reuters was protecting our data throughout the flow, which was critical for adopting AI across our organization.”

Trust built on reputation and practical law
For this Assistant General Counsel, trust in an AI solution starts with its foundation. CoCounsel’s integration with Practical Law and backing by Thomson Reuters were key factors in the company’s adoption.
“One of the things that brought us to CoCounsel was the fact that it’s made by Thomson Reuters and integrates Practical Law,” the AGC says. “You could pick up a new project or contract type, read the Practical Law entry, and be good enough to run with everybody — or even run circles around some people.”
This depth of content and reputation gave the company confidence in CoCounsel’s capabilities, especially when handling unfamiliar or complex legal tasks.
Security and data integrity at scale
Operating in a highly regulated environment, the company places a premium on cybersecurity and data privacy. CoCounsel’s architecture and Thomson Reuters reputation helped meet strict requirements.
“We have pretty strict cybersecurity requirements,” the AGC notes. “One reason we chose CoCounsel was because we could feel confident that Thomson Reuters — a huge, reputable company — was protecting our data throughout the flow.”
The AGC also emphasized the importance of understanding how data moves through AI systems, especially in configurations involving multiple vendors or embedding models.
“Each hop in the data flow could represent another vendor, another potential leak,” he explains. “We expect outside counsel to understand how to keep data safe end-to-end.”
Empowering legal and business teams
Beyond the legal department, CoCounsel is helping the company accelerate support across functions like procurement and HR. Its ability to provide quick, actionable insights — even to non-lawyers — is a gamechanger.
“It’s especially helpful when someone can ask CoCounsel to analyze a document and spot issues,” the AGC says. “Non-lawyers accessing legal-type advice quickly is huge.”
Advice for legal leaders: Use it, but use it wisely
Looking ahead, the AGC encourages legal leaders to embrace AI — but with discernment.
“You have to use it. It’s going to be the future,” they say. “But you also have to recognize when you shouldn’t use it. Strategy and judgment still require human insight.”
