From early 90’s until 2010, both Pirjo and Ari worked for a CRM system vendor. In 1986, Ari was one of the partners founding AddWise Oy which in early 90’s published a CRM system called PROSPEKTI. It gained a very good market share in Finland. Some years later AddWise Oy was sold to a Norwegian company and changed its name to Software Innovation Finland Oy but it still continued to develop PROSPEKTI further. When Innofactor Plc bought Software Innovation Finland Oy, Ari and Pirjo decided to start a company of their own. Their experience from hundreds of projects is now available to you.
