What Appresso does

Appresso is a Norwegian private development firm (Appresso AS, org. nr. 913601238) founded in 2014 and headquartered in Oslo. The company specializes in backend and frontend development for web and mobile applications, API integrations, and cloud-native infrastructure, with a core technology stack of Python/Django, JavaScript/React, deployed on Kubernetes/Docker and Microsoft Azure. Its flagship product is the Appresso Medlemssystem, a proprietary membership management system designed for member-based organizations, offering automated fee collection (via Vipps, Nets, and bank integrations), email/SMS communications, flexible organizational hierarchies, member self-service portals, and built-in GDPR and WCAG compliance. The firm also maintains a proprietary IEVV web framework used as the foundation for large-scale client deployments.

The company operates a hybrid revenue model: professional services for bespoke backend, frontend, and integration projects (project-based pricing on consultation), subscription/recurring revenue from Medlemssystem deployments, and managed cloud operations for hosted applications. Notable clients include Arbeiderpartiet (Norway's Labour Party), for which Appresso operates a platform of 100,000+ pages across 600+ websites spanning county, municipality, and local branches; Vipps (during the Vipps/BankID/BankAxept merger); North Sea Container Line; Universitetet i Oslo; FlipClass; and BDO CERT. Go-to-market is direct CEO-led engagement with Norwegian enterprises, government organizations, and membership-based associations, supplemented by referrals and word-of-mouth; the company does not engage in paid marketing or content marketing at scale.

Appresso is founder-led, with CEO Tor Ivar Johansen and CTO Espen Angell Kristiansen heading a team of 8 full-time staff plus one part-time developer. Most team members are educated at the University of Oslo's Department of Informatics, giving the firm concentrated Python/Django and web-architecture expertise. The company is privately held with no disclosed institutional investors, no funding rounds, no subsidiaries, and no M&A activity; all operation is domestic to Norway. Revenue is not publicly disclosed.
