1990 SysOpen was founded when Kari Karvinen, Jorma Kylätie and Matti Savolainen established a customised system development service provider, SysOpen Yhtiöt Oy (now Digia Plc). SysOpen initially operated in Helsinki and Tampere in Finland, and Stockholm in Sweden.
1991 SysOpen acquired the Primas production and materials management software business from the then Nokia Data Oy.
1992 SysOpen concluded a sole agency agreement with Australian-based CLS Research Pty Ltd to represent eForm printout software in the Nordic countries. Later in the 1990s, SysOpen and CLS extended their partnership in ownership terms, with most of CLS' businesses transferring to the USA, where SysOpen became a minority shareholder in the resulting US company, Create!Form International Inc.
1999 Based on its revamped growth and internationalisation strategy, SysOpen opened an office in Kuopio, established a British subsidiary, SysOpen Limited, and SysOpen Object Team Ltd specialising in object technology, and acquired Commit; Material Automation Oy in support of its logistics and CRM information system strategic goals. Following this, in the autumn of 1999, SysOpen was listed on the Helsinki Stock Exchange. At the year-end, SysOpen acquired Dycom Oy, again in support of its growth strategy with respect to information system projects within the telecommunications sector and EP-Logistics Oy in pursuit of the creation of broad-based competencies in comprehensive logistics systems. Through the Dycom transaction, SysOpen acquired a 49 per cent holding in Callcom Oy, a provider of telephone exchange accessibility systems, and by the beginning of the following year had bought the remainder of Callcom shares from Siemens AG.
2000 SysOpen bought QL-Systems Oy, further broadening its comprehensive logistics system expertise, Benefect Oy, for its software product solutions know-how, Sypal Oy to bolster its capacity as an information system solutions provider and Tietovalmis Group Oy, giving it a stronger base in Jyväskylä.
2001 SysOpen acquired 51 per cent of the British company, Intellectech Ltd, renamed SysOpen UK Limited. Later, SysOpen bought all of its shares, broadening the parent company's international presence, despite its closure of its loss-making Stockholm unit at the end of the year.
2002 SysOpen decided to focus more single-mindedly on its profitable core business – the creation of, and consultancy in, enterprise application solutions – involving divesting non-core operations and rationalising and streamlining the Group and its structure. The related Logistics consulting service businesses were sold to their management on an MBO basis.
2003 SysOpen continued to streamline, selling the non-core subsidiary Callcom Oy to its employees. SysOpen sold its holding in Create!Form International Inc to Bottomline Technologies Inc, a US listed company and, in line with its growth strategy, submitted a tender offer for all shares in the ten times larger Novo Group, after negotiating a combination merger agreement with Novo's Board of Directors. However, Novo's Board unilaterally withdrew from the agreement in favour of a competing bid from the Swedish WM-data AB (publ.). SysOpen viewed the risks attending the acquisition as having grown after the bid had been publicised, jeopardising the possibility of providing increased shareholder value in the wake of the acquisition, alongside the attendant rise in the acquisition price based on share price hikes. For these reasons, SysOpen withdrew its offer.
2004 SysOpen purchased Done Information's Software Solutions business, bolstering its customer base and local presence in the Jyväskylä region and broadening its technology and product solution offering. The year also saw the acquisition of Yomi Software's Kuopio operations to strengthen SysOpen in the same way there, and boost its competitiveness in industry and the telecommunications sector. At the year end, SysOpen sold its British subsidiary, SysOpen UK Limited, to Novo Ivc Limited, due to changed circumstances and waning prospects in the subsidiary's business area.
