Add-On Products

What Add-On Products does

Add-On Products is a privately held Danish software company founded in 2000, headquartered in Vejle, Denmark, that builds workspace and meeting-room management software native to the Microsoft ecosystem. Its platform, anchored by the Resource Central meeting room booking system and complemented by the Workspace mobile booking app, OfficePlace sensor solution, Insights workplace analytics, and a digital signage suite (Digital Sign Client, Workspace Display, and Ariadne), extends Microsoft Outlook, Exchange, Microsoft 365, and Teams to handle desk booking, room reservations, visitor management, catering/service ordering, and occupancy analytics. The product is sold primarily to enterprise and public-sector organizations and is localized in 15 languages across 40+ countries, with cited deployments including Ørsted (around 7,000 employees across 6 countries, 1,000+ meetings/day), Genesis Housing Association (£1m annual savings and 285 desks freed), Wessex Water, UZ Leuven, and Aarhus Municipality.

The company monetizes through subscription software licensing (per-seat/user or site license on annual or multi-year terms), recurring support and maintenance, and supplementary hardware sales (sensors and display panels). Distribution is hybrid: direct enterprise sales teams in Europe and North America plus an international reseller and technology-partner program, with product-led acquisition supported by a 1-month unlimited free trial and on-demand demos. Marketing emphasizes content (blog, case studies, on-demand webinars), SEO, and email nurture targeting the hybrid-work and sustainability themes of enterprise buyers.

Add-On Products is founder-owned with no disclosed external institutional investment and operates without subsidiaries. CEO Peer Astrup is the named founder/owner; a VP of Sales for North America has been added to support US-market expansion, alongside dedicated European and North American sales/support contact channels. Public reporting flags 536,216+ licenses sold, 128,824+ meeting rooms managed, 27,611+ digital signs, a 4.92/5 customer support rating, and GDPR-compliance posture (privacy policy updated September 2025).
