9. 9 Entrepreneurs’ views on SPARK’s added value Caspar Hobbs, Founder & CEO, Mergermarket “SPARK saw exactly what we were trying to do when we simply had a business plan and lots of enthusiasm, they backed both. They have been great partners and shareholders, supportive and encouraging from the earliest stages of the company and in every phase of its growth. They understand entrepreneurs because they are entrepreneurs. Their wisdom and perspective always added great value.” John Gallagher, CEO, Footfall “SPARK led two rounds of funding and their support over five years was instrumental in the eventual sale of our business to Experian in 2005. SPARK were also major contributors to reshaping Footfall’s strategy, assisting in the company’s transition from a hardware vendor to a provider of business intelligence to retailers.”
