Scissero and Robin AI: What the Deal Says About the Future of Legal Work

On 9 December 2025, Walmer client Scissero announced it had acquired the managed legal services business of Robin AI. Around 75 staff transferred, along with several members of Robin AI's leadership team.

A bit of background helps. Robin AI was one of the UK's best-known legal technology companies, building AI for contract review alongside a services team that did the work for clients. According to press reports, it ran into difficulty after failing to close a new funding round. Scissero bought the services side. The technology business was reported to be in separate talks.

Scissero is an interesting buyer. It started life in 2017 as an AI business, later merged with a specialist finance law firm, and is now a regulated UK law firm in its own right, led by Mathias Strasser, a seasoned entrepreneur and former City lawyer. It's clients are mostly in financial services.

Why does the deal matter?

For years, the question in legal technology was simple: can AI make legal work faster? The answer turned out to be yes, at least for contract review, document drafting and other repeatable tasks.

The more interesting question is what happens next. Does the value sit with the company that builds the tool, or with the firm that uses the tool to deliver the work? This deal is a vote for the second option. A firm that owns the technology, employs the lawyers and carries the regulatory responsibility can offer something a software licence cannot: an outcome, with someone accountable for it.

Tools or services: who wins?

Selling AI software to law firms is a hard business. Sales cycles are long, firms are cautious and the underlying models are improving so quickly that last year's product advantage can disappear.

Delivering legal work with AI inside it is a different proposition. The client is not buying a tool and hoping their team adopts it. They are buying a reviewed contract, a completed fund onboarding or a negotiated agreement, at a price and speed that would not be possible with people alone.

Is that a law firm with good technology, or a technology company with lawyers? At some point the label stops mattering. The client cares whether the work is right, fast and reasonably priced.

Where do people still matter?

It would be easy to read this as a story about lawyers being replaced. That is not what the deal shows. Scissero took on about 75 people, which is an odd thing to do if the plan is to remove them.

Financial institutions and other sophisticated clients still need:

• Judgement. Knowing which clause matters in this deal, for this client, in this market.
• Accountability. A regulated professional who is answerable if the advice is wrong.
• Context. An understanding of the commercial situation behind the document.

The likely future is a division of labour. Technology takes the volume. People take responsibility for quality and for the decisions that carry risk.

What does this mean for other professional services?

Law is not the only profession working through this. The same questions are being asked in accountancy, tax, audit and consulting. We see a version of it in our own field. Parts of preparing an R&D tax relief claim can be made faster with technology, such as gathering cost data or structuring information. Deciding whether a project meets the definition of R&D, and being able to defend that position if HMRC asks, still takes experienced people who are prepared to put their name to it.

So where is the line between what should be automated and what should not? A reasonable test: if getting it wrong would need someone to pick up the phone and explain, a person should own it.

What should founders take from this?

For anyone building AI products for professional services, three points stand out.

1. A good tool is not the same as a good business. Distribution and trust count for a lot.
2. Regulated sectors pay for accountability. Building that in can be worth more than another feature.
3. Funding conditions can change quickly. A company with strong technology still needs enough runway to reach the point where it pays for itself.

The opportunity in legal technology was never only to build another AI tool. It is to change how the work gets delivered. This deal is one early example of what that looks like.

Frequently asked questions

What did Scissero acquire from Robin AI?

Scissero acquired Robin AI's managed legal services business in December 2025, with around 75 staff transferring. Robin AI's technology business was not part of the deal.

What is Scissero?

Scissero is a regulated UK law firm that combines AI with lawyers to deliver legal services, mainly to financial services clients. It was founded in 2017 as an AI business and later merged with a specialist law firm.

Will AI replace lawyers?

AI is automating repeatable legal tasks such as contract review. Judgement, accountability and client context still require qualified people, so most observers expect a combined model in which technology handles volume and lawyers remain responsible for quality.

Can legal technology companies claim R&D tax relief?

They can where the development work seeks an advance in science or technology and involves technological uncertainty, for example developing new AI methods. Routine configuration of existing tools is unlikely to qualify.

Key takeaways

• The buyer is a regulated law firm that uses AI, not a software company selling to law firms. That distinction matters.
• Repeatable legal work is being automated quickly. Accountability is not.
• Clients in financial services want speed and lower cost, and still want a named person to stand behind the advice.
• The same pattern is appearing in accountancy, tax and other professional services.
