Why Clio spent $1bn on a legal research company
The boss of the legal tech giant thinks the real opportunity with AI lies in redefining value and expanding into a vast untapped legal market.

I caught up with Jack Newton at the Rosewood Chancery in Mayfair, in between sessions at Clio’s conference. Newton is the founder and chief executive of Clio, the $5 billion legal tech company used by more than 400,000 legal professionals globally, and one of the key players driving AI adoption across mid-size and increasingly, large law firms.
On the main stage, he opened with a stark warning: the cost of “standing still” or lagging in adopting new technologies can cost firms about £100,000 per lawyer, per year.
The message comes as Clio pushes into a new phase following its $1 billion acquisition of vLex, a deal Newton has described as a “watershed moment” for the industry.
He is also quick to challenge some of the industry’s default assumptions, including that AI is primarily about saving time or that clients should expect cost savings in the new AI era.
“In any other industry, if you’re delivering a superior product on a quicker timeline, that’s something clients would pay a premium for and not be asking for a discount,” he says.

An inflection point
The tension Newton points to is already playing out across the industry. Law firms are investing heavily in AI tools, but many are not yet at the stage of translating that into clear returns.
At the same time, the long-held billable hour model is in flux. Clio’s recent survey of UK and Ireland legal professionals found that 53% of matters are now being billed as fixed or flat fee, edging out the billable hour.
“The billable hour is fundamentally incompatible with AI,” he says. “Law firms need to move rapidly towards orienting what they deliver to clients around the value they are delivering.”
While the death of the billable hour has been debated for years, he believes AI will force the issue.
“The final nail in the coffin is AI. It’s just not tenable,” he says. “Law firms will not be able to properly harvest the benefits of AI if there’s an embedded disincentive to do that through a structural reduction in their billable hours.”
A $1bn signal
Clio’s $1 billion acquisition of vLex last year is a reflection of the company’s broader ambition, and draws parallels to Harvey’s strategic partnership with LexisNexis. Harvey also reportedly considered buying vLex in 2024 according to tech publication The Information.
On one side, Clio had built infrastructure for the business of law - managing matters, workflows and operations across thousands of firms. On the other, vLex brought a vast repository of legal data, spanning more than 100 jurisdictions, built up over decades.
Bringing those together, Newton says, was about unifying two worlds that had largely operated separately.
“We wanted to combine the business of law and the practice of law in one platform,” he says.
Models are only as useful as the data and context they are grounded in. This is also where Newton sees a clear dividing line emerging in the market.
“There will be companies that are essentially thin wrappers on top of the foundation models,” he says, “and those that have a real, defensible layer of data and workflow integration.”

What do City lawyers actually do each day?
For a closer look at the day-to-day of some of the most common types of lawyers working in corporate law firms, explore our lawyer job profiles:
Scratching the surface
For all the attention on AI, he says most law firms are still only scratching the surface of what it can actually do.
“I think even understanding the art of what’s possible is a big challenge for lawyers and even innovation leaders at law firms,” he says.
“We have incredible tools, but teaching people how to use them is almost the hard part of the work.”
In many cases, firms are deploying multiple standalone tools and expecting lawyers to figure out how to use them.
You could freeze the models where they are today and it would still take five years...
“People are throwing these AI point solutions over the fence to practitioners and saying, ‘here’s tool A, here’s tool B, here’s tool C — go make use of them’, but lawyers then struggle with questions like, ‘how do I actually use it?’ and ‘when’s the right time to use it?’”
That challenge is compounded by the speed at which the technology is evolving.
“Even if you formed a perspective a few months ago, you’re already out of touch with the capabilities based on the developments we’ve seen in just the last three months,” he says.
“You could freeze the models where they are today,” he says, “and it would still take five years for those capabilities to properly diffuse through law firms.”
The mid-size advantage
While much of the legal tech narrative focuses on the largest firms, Newton sees a different competitive dynamic emerging.
Mid-sized firms, he argues, may have the most to gain. They are large enough to benefit from scale, but not so large that they are slowed by complexity.
“If mid-market firms are navigating that sweet spot effectively, they can be in a really ideal position in terms of the speed at which they can move and how quickly they can deploy new technologies,” he says.
They can be more nimble and agile...
“They can be more nimble and agile than some of their slower moving counterparts in large law firms.”

The latent legal market
Much of the current discussion around AI focuses on productivity - doing the same work faster - but that only captures part of the opportunity.
Newton points instead to what he calls the “latent legal market”: the vast pool of demand that exists but is never served, often because traditional legal services are too expensive or difficult to access.
In practice, that includes everything from small business contracts and compliance to individual disputes and advisory work that simply never reaches a lawyer.
“There is a latent legal market, where over three quarters of legal demand is not currently serviced by lawyers. “It’s a huge opportunity that lawyers can and should go after while leveraging AI,” he says.
But capturing that opportunity will require change.
“It’s going to require a new type of thinking from lawyers in terms of how they price, package and deliver legal services to tap into that market.”
