This week on The Merri-Cast, I’m joined by the inspiring David B. Horne – founder of Add Then Multiply and Funding Focus. 

In this episode, we explore his career, one that spans global finance, corporate leadership, and a mission to level the playing field for underrepresented founders. 

From collecting newspaper payments as a boy in Canada to raising £60 million in funding for AIM-listed companies, David’s journey is full lessons and reflections for anyone starting and growing their business. 

In this inspiring episode, David shares:
• How a paper round sparked his lifelong interest in business and finance.
• The story behind Add Then Multiply and his formula for helping entrepreneur’s scale. 
• The shocking truth about funding inequality and what David is doing about it. 
• The lessons he learned, both from successful exist – and ventures that didn’t go to plan. 

David also talks about his two books, Add Then Multiply and Funded Female Founders, and how writing them gave him clarity, credibility, and a platform to advocate for fairer access to funding.

Tune in to hear David’s perspective on what it really takes to grow, scale, and sustain a business — and why the key to success is knowing when to let go.
