Slaughter and May has financially backed AI company Luminance for the third time, in a £10m fundraising round that values the Cambridge-born company at $100m (£77.5m).

Slaughters first took a 5% equity stake in the company back in 2017 after trialling the platform, before investing further as part of a £10m Series-A round later in the year. That round valued the company at £37m.
