A UK start-up that uses Artificial Intelligence to produce creative marketing copy is planning an expansion into the US market.

Phrasee, a London-based firm that creates marketing copy for brands including Domino’s, Virgin and Superdry, has raised $4m to fuel its investment into natural language generation and deep learning technology.

The company, which was founded in 2015, works with clients to generate copy for email subject lines, Instagram ads and push notifications on smartphones through its machine learning technology.

The funding round was led by Albion Capital, a venture capital group with a £1bn fund that has increasingly shown interest in investing in early-stage UK companies.

“From day one, our vision has been to transform how brands speak to their customers online," said Parry Malm, Phrasee co-founder and CEO.

"Having built awesome relationships with some of the most progressive brands in the UK, we’re now ready to take our AI technology and approach to the US market.

“The investment from Albion, and the experience it will bring to the board, will supercharge our global ambitions.”
