From City law to startup founder: Betting on the rise of fractional lawyers

From City law to startup founder: Betting on the rise of fractional lawyers

Correm founder Kenzo Onumonu wants to give fractional lawyers the infrastructure to work independently.

Fractional legal work - where lawyers effectively work part-time across a portfolio of clients - has traditionally occupied a slightly awkward corner of the market, often associated with lawyers working independently between permanent roles rather than actively choosing it as a long-term career.

Kenzo Onumonu thinks that is changing.

The former Bird & Bird lawyer and startup general counsel is the founder of Correm, an AI-powered platform providing the tech and infrastructure for experienced lawyers to run fractional practices and connect with companies looking for legal support.

“Fractional work up until recently was very much not a choice, or at least not a deliberate one,” Onumonu said. “People that were in between work or jobs would sort of position themselves as fractional freelance.”

“Now it’s becoming more of a deliberate way of working.”

The shift is being driven by two trends. More lawyers want greater flexibility and are building portfolio careers, while advances in AI are making it possible for individual practitioners to handle more work independently without the infrastructure of a traditional law firm.

It is a model he arrived at after experiencing the problem himself.

Onumonu began his career as a corporate paralegal before training and qualifying into Bird & Bird’s corporate venture capital team in London.

A few years later, he moved to Deliveroo to broaden his experience in-house. He later joined startup incubator Entrepreneurs First in a legal role, handling a high volume of early-stage venture capital fundraisings alongside operational legal matters.

He later worked as a legal director at rapid grocery delivery company Wheezy and as a GC at milk delivery startup Modern Milkman, giving him several years working inside the high-growth companies Correm now serves.

You could say he had a portfolio career of his own, but he still had the desire to do something more.

“I have always had that entrepreneurial itch,” he said. “I always knew that I was going to eventually do my own thing.”

The opportunity emerged after Onumonu moved to Dubai and began working fractionally. He reached out to his former employer Entrepreneurs First to ask whether any of its portfolio companies needed similar support.

Several did, and those startups became some of his first fractional clients, convincing him there was demand from both sides of the market.

“Lots of businesses welcome working in this way with their legal function and lots of lawyers value the flexibility, but the infrastructure to actually enable that to happen at scale didn’t really exist,” he said.

Onumonu was initially piecing together his practice using a collection of everyday software.

“I was using a bunch of disparate tools just to run the practice,” he said. “I had Excel for time tracking, Word for invoices. I was using about 10 different tools just to do what I needed to do.”

That experience prompted the development of an early version of Correm, then called Crumb, which was initially used by only a handful of lawyers.

“It wasn’t very good, but it worked for the three or four lawyers that were using it,” he said.

Correm was founded in 2025, and Onumonu bootstrapped the business until quite recently, when it closed the first part of its current fundraising round. The proposition has expanded and the platform includes backend infrastructure covering areas including billing, matter management and data aggregation, while also connecting lawyers with new clients through the platform.

The founding cohort and current applications put it at just around 30 lawyers.

The platform is geared towards experienced lawyers who have typically served as senior legal counsel or led legal teams at venture-backed startups and scaleups.

Onumonu said that background is important because working inside a high-growth business requires lawyers to deal with a wide range of issues, often at a considerable pace.

Correm does not employ lawyers or require them to work exclusively through its platform. Lawyers can bring their existing book of clients, find additional work through Correm and set their own rates.

The client relationship also remains with the lawyer, with Correm charging a platform fee for its backend services and access to its marketplace.

“It’s infrastructure rather than a kind of complete trade in terms of you have to be a Correm lawyer,” Onumonu said.

The pitch is aimed at early-stage companies that have reached the point where regularly sending work to external firms is becoming expensive, but hiring a permanent general counsel may not yet make sense.

A fractional GC can instead take responsibility for the legal function, handling work internally where possible and managing external firms when specialist advice is required.

The work can cover everything from commercial contracts and employment matters to fundraising, due diligence and employee incentives.

Correm supports different pricing structures, although Onumonu said fractional GCs typically work on a day rate or monthly retainer, giving companies greater predictability over their legal spend.

The platform is mainly focused on the UK, with some lawyers in the US and sights set on potential expansion there and in the UAE.

AI sits at the centre of Correm’s attempt to make the model scalable.

“The lawyers using Correm are implementing AI into their workflows, and they want to move as quickly as their clients so they can serve more of them and scale their practices,” he said.

Correm is focused on developing AI functionality around the way in-house lawyers work rather than focusing primarily on document generation and research.

One area involves giving lawyers their own AI agent embedded within their clients’ workspaces, allowing the technology to gather business context before the lawyer provides advice.

Onumonu uses contract negotiations as an example. A lawyer reviewing redlines in isolation might suggest pushing for the strongest possible contractual position, but the appropriate advice could be very different if the counterparty is strategically important and has made clear that the terms are non-negotiable.

“Rather than focusing on AI workflows that are kind of front and centre in the traditional sense in the market, we’re focusing on how to use AI to create the absolute best in-house lawyers.”

Correm lawyers are expected to bring in external specialists when work requires expertise beyond their own, while the company is also discussing partnerships with law firms.

“Our view is that there is a space for every incumbent legal service,” he said. “We don’t think that one is going to completely dominate because the whole ecosystem requires every part of it.”

There are already alternative legal services providers offering flexible lawyers such as Pinsent Masons Vario and A&O Shearman’s Peerpoint, as well as independent fractional GCs and a growing group of AI-native law firms.

Onumonu argues Correm is making a different bet by giving lawyers the tools to operate independently rather than owning the end-client relationship itself.

“We’re effectively on a mission to turn great individual lawyers into solo AI-native practices,” he said.

Onumonu said one of the biggest lessons from moving into entrepreneurship has been the value of building within a market he already understands.

“Starting a business in an area that I had domain expertise in was really important,” he said.

As technology makes products cheaper and faster to build, he believes that experience becomes particularly valuable for lawyers considering starting businesses of their own.

“If you have some experience that you can leverage and create something with, and the idea is something that people need, now is definitely the time to build and try something out.”
