The company's chief executive, Gary Wingrove, said in a statement: "Love Agency has been a pioneering digital business for over 10 years, and we are excited to be welcoming them to KPMG.
"The addition of Love Agency’s capabilities will provide greater scale for our fast-growing KPMG Digital Delta business and further enhance our market position as a global leader in delivering true enterprise-wide digital transformation.”
No amount was mentioned in connection with the acquisition.
Housseas and Gougoustamos, who were now KPMG partners, built a team of technologists and designers, including solution architects, UX/UI specialists and mobile developers, the statement said.
Love Agency had collaborated with KPMG during the last 12 months to co-deliver successful client projects, allowing each business to test what would now be a full-time relationship.
KPMG's head of Management Consulting, Ian Hancock, said: “We are increasingly being asked to assist our clients to re-imagine and re-invent themselves. This often means supporting their transformation into world-class digital enterprises using advanced technologies, data and human insights.
“Bringing Love Agency into KPMG Digital Delta means we are better able to deliver end-to-end digital transformation solutions that seamlessly connect our clients’ front, middle and back offices.”
Housseas said: “Having spent the last decade researching and delivering customer centric products in highly scalable enterprise environments, we are delighted to embark on the next phase of our journey.
"As part of KPMG, we’ll be able to bring together a broader set of digital capabilities, work with some of the smartest minds in the business and at a larger scale than previously possible. This will ensure our clients have the necessary support to achieve their transformation goals.”
