Phrasee has closed a $4 million series A funding round.

The investment will fuel the London-headquartered marketing technology company’s international growth plans, including scaling up its new US operation in San Francisco and the recently announced expansion of its UK team.

Albion Capital Group led the round, with follow-on funds from existing investors including global digital communications business Next Fifteen (Next 15) and angel syndicate Galvanise Capital.

Next 15 and Galvanise announced their initial investments in 2016.

Phrasee, which counts Virgin, Domino’s, Superdry and The Times amongst its clients, is the market leader in artificial intelligence marketing language generation.

It combines natural language generation and deep learning to arm marketing teams with brand-compliant copywriting firepower.

Phrasee’s technology writes email subject lines, Facebook and Instagram ads and push notifications that perform better than human-written versions, consistently delivering outstanding results for global brands.

“From day one, our vision has been to transform how brands speak to their customers online.

“Having built awesome relationships with some of the most progressive brands in the UK, we’re now ready to take our artificial intelligence technology and approach to the US market,” said Parry Malm, Phrasee co-founder.

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

Founded in 2015, Phrasee is the go-to solution for ambitious, intelligent and analytical marketers.

“We have a solid track record of supporting the expansion of high-performing UK businesses into the US and understand the formula for long-term success,” said Emil Gigov of Albion Capital, who will be joining Phrasee’s board.

“Based on Phrasee’s commercial track record to date, client-focused culture, product leadership and the calibre of its ever-expanding team, we believe the company has an incredible future and are proud to be part of this next phase in its growth story.”
