Mr Tuck, previously the group chief executive Europe at Kin + Carta, brings 25 years of experience in the tech sector to the role.

He succeeds Chris Martin, who has led the business since 2014. Mr Martin will remain with the business and continue to be a significant shareholder.

Waracle specialises in mobile apps and digital products and has a client base that includes Lloyds Banking Group, Royal London, Roche and Imperial College London. The company is backed by investorgrowth capital investor BGF.

At Kin + Carta, Tuck delivered end-to-end digital services for global clients and is experienced in scale-up and business integration.

His appointment comes at an exciting time for Waracle which recently announced the acquisition of Glasgow-based Screenmedia and a multi-million-pound deal with Scottish Power Energy Networks.

Mr Tuck has worked in technology services for 25 years, mostly in London. He held senior positions at Thoughtworks, Scott Logic, and The App Business before Kin + Carta. He returned to Edinburgh in 2019.

In 2024, he was named as CEO of the Year in the digital transformation category by European CEO Magazine in 2024.

Mr Tuck said: “I am hugely excited about the journey with Waracle, which is a company I have followed for a long time. There is a buoyant tech sector in Scotland and we know that demand for high-quality tech services will continue to grow.

“Waracle has grown to a business with over 200 employees and a strong client base across the UK and Europe. Now there is an opportunity to accelerate that growth and invest in new capabilities, particularly data and AI, and use that to bring greater value to clients.”

He added: “The next chapter is exciting for everyone here. There is an opportunity to substantially increase the size and impact of the business over the next two to three years.”

Mr Martin said: “David’s appointment demonstrates the ambition for Waracle to continue its growth to the next level.

“His experience in scale up and his track record in building teams who do great work, and enjoy themselves, makes him perfect for this role. He is pragmatic, hard-working, ambitious and likeable.”

Waracle, which has offices in Edinburgh, Glasgow, Dundee and London has more than 200 employees.
