Alfi, which is headquartered in Miami and a second US base in Denver, has had an office in Belfast since January 2019, and is seeking to expand its European business.

Kevin Buchler, vice-president, UK and Europe operations, at Alfi, will oversee the London office, which is based in Waterhouse Square, Holborn.

Alfi supports digital out-of-home advertising, such as through targeting, reporting and performance insights, and has recently signed a letter of intent with programmatic digital out-of-home network Lemma to promote each firm’s operations and services.

Dr Paul Pereira, founder and chief executive officer at Alfi, said: “UK advertising spend is predicted to reach £27.7bn this year.

“Kevin is well suited to lead our UK and international operations, bringing extensive industry experience to the team. His knowledge, network, and connections put us in a strong position to expand outside of the US.”
