Summary: Thank you for reviewing my profile! If you would like to accelerate your enterprise sales capability at any stage of your business lifecycle, it could be worth talking to me. I have more than 30 years of business experience in enterprise sales leadership and as a sole contributor. The roles I have had have involved developing new geographies and verticals with leading edge technology delivering business advantage. The challenges involved in getting the first 10 and then 10-100 customers have not changed, the approach and way to achieve them have! Since 1981 when 1GB of hardware storage cost £1million with no mobile phones or internet to the current social and digital world I have been involved with enterprise technology. Being part of some great companies large and small; early stage through to mature businesses, I have been able to connect with like-minded individuals who have been colleagues as well as customers and have made life friends during this journey. The mobile telecoms sector became a focus for me in the mid 1990's as it expanded exponentially with its need for new and innovative technology to attract and retain valuable business and consumer customers Stage 4 cancer; being tied-up and gun point and missing quota (once) have also been part of my business journey. Married 31 years, have 2 children now aged 26 and 23 and a Jack Russell. Lived in London since leaving Birmingham University in 1981 and went to school in Fareham, Hampshire as well as spending 3 years of my schooling in Singapore. A small property portfolio which will (hopefully) be my pension. If you also want to talk about travel; sport eg Football, Cricket; theatre, tech trends, bespoke mobile apps, telco, Cloud, SaaS then I am quite likely to be your man. I am a father, husband, son and a salesman!
