Chris Harrison: Collstream Strong growth, impressive client list, and zero debt for this IT firm Our experts We are a team of writers, experimenters and researchers providing you with the best advice with zero bias or partiality. Chris Harrison, 33 Company: Collstream Web: www.collstream.co.uk Self-taught IT developer and technical design expert Chris Harrison co-founded Collstream in 2005, aged 26. Since then, the Derby-based business has grown into a leading provider of SMS, voice messaging and IVR solutions to clients including utility companies, Premier League football clubs and retail stores. Due to Harrison’s and co-founder Ian Maxfield’s decision to eschew external investment, the business has remained debt-free since day one.This makes its 2012 turnover of £3m, and its 50% year-on-year growth, arguably even more impressive. Harrison is now predicting continued strong growth and expansion into new markets as use of mobile technology and SMS continues to increase. Share this post facebook twitter linkedin
