An artificial intelligence (AI) company co-founded by a former adviser to Linklaters, Lewis Liu (pictured), has received a £13m investment from Goldman Sachs and investment company Temasek.

Eigen Technologies, which counts Liu's former employer Linklaters and Goldman Sachs among its clients, is now set to target more law firm clients following the investment.

The company's technology automates the extraction and classification of data from legal documents, with a team of 50 people working at Eigen across London and New York.

Liu previously spent two years as a senior adviser at Linklaters, where he was a co-founder of the tactical opportunities team – a role in which he advised the firm's partners and clients on high-yield fixed-income securities, distressed opportunities, and hedge fund activism.

Prior to joining the magic circle firm, he was a physicist at the University of Oxford and held roles at private equity firm Aleron Partners and management consulting firm McKinsey & Company.

In November, Eigen hired former Slaughter and May corporate partner Adam Eastell as its head of legal and first general counsel. Eastell joined Slaughters in 2004, making partner in 2011 before leaving the firm in 2016 to work as an independent consultant.

When asked about the key differences between Eigen and competitors Kira and Luminance, Eastell said: "The key things are that it's very flexible, in that you can ask any question of any document. That means it can be applied to a variety of use cases. Also, to train our platform takes considerably less training data, which reduces lawyer time and means that Eigen can be run on smaller datasets. In terms of output, Eigen brings back the precise answer to the question asked. We don't just bring back the clause for humans to review, but go into the clause to pull out the answer.

"The other thing that's quite different is that, with others, client data often goes back to the hive mind to help the machine learn. Our client's data stays with our clients – we don't need that data to improve our AI platform. We don't store anything. Obviously for law firms that's quite important as they don't want that data necessarily going back to a hive mind and assisting competitors."

Dutch financial institution ING and investment bank Evercore have also signed up to Eigen's services.

Last month, a report by commercial property company CBRE showed that almost half of London's law firms are expecting to see job cuts at junior and support levels due to firms' adoption of AI.

Between 43% and 45% of the 100 law firms surveyed said they believed there will be a reduction in headcount at junior and support levels due to firms' adoption of AI, with 5% of respondents saying they expect cuts of more than 20%.
