What others say about us
“Add then Multiply was an essential advisor to The Centre (of which I was a co-founder), helping with its set-up, ongoing operations and growth prior to sale over its 7 years of independent business. He was astute, constructive and diligent and a pleasure to work with throughout – in short, highly professional. I would highly recommend him.”
Martin Porter, The Centre International Limited
“I worked with David on several fundraising projects and a substantial global acquisition. His FACE methodology is a refreshing take on fundraising, acquisitions, consolidations and exits, and he has a clear focus on bringing awareness and understanding of this to the world of entrepreneurship.”
Delphine Currie, Partner, global law firm
“ATM was instrumental in helping me raise £55 million and acquire 7 companies over a three year period, resulting in 10-fold growth in the business.”
