I have built two companies (Handpoint's predecessors). First being one of the first internet companies in Iceland doing web site development and content management software. Sold that and used proceedings to setup another venture focused on building software for PDA's (handheld computers). Initial market was for utility companies for meter reading and then retailers for inventory management and product ordering. Sold off that business and setup current company focused on powering payments for next generation point of sale ISVs (developers).
