Daymaker is a Norwegian startup that automates employee birthday celebrations by coordinating cake deliveries to workplaces. The company was founded in Oslo in August 2025 under the name Jubelbud — Norwegian for "celebration messenger" — and rebranded to Daymaker in early 2026 after acquiring the daymaker.com domain.126
William Lindholm, who turned 20 in early 2026, is the CEO.3 Simon Dieu is the CCO and co-founder.2 Abeer Rao, the CTO, moved from India to Helsinki at age 17 to study quantum physics before joining the company.2 Ragnar Bø, a Norwegian tech investor, chairs the board.2
Before settling on cakes, Lindholm and Dieu considered automating mortgage refinancing with AI. Bø rejected the idea, telling them it was "a cowboy business."3
Daymaker's software integrates with HR information systems including ADP, Rippling, Simployer, and UKG to pull employee birthdays automatically.1 Companies set rules for cake size, messaging, and delivery once; the system then schedules orders, coordinates with local bakeries, and sends reminders two weeks, one week, and one day before each birthday.1
In Oslo, cakes are baked at Øvre Sem Gård, a farm dating to 1886 that houses Holtsmark Konditori. Michael Lunga, the head baker and owner, produces cakes from scratch on-site.5 Lunga selects ingredients locally where possible and builds the production schedule around freshness rather than volume.5 "Quality begins with respect for the raw ingredients," Lunga has said. "If you start with good produce and take your time, the flavor speaks for itself. There are no shortcuts here."5
The Oslo menu includes seven cakes: a cream cake layered with strawberry jam, a carrot cake with cream cheese frosting, a marzipan cake, a baked cheesecake made with Rørosrømme (a traditional Norwegian sour cream from Røros) and blueberries, a gluten-free raspberry delight built on an almond cake base with buttercream, a chocolate cake with raspberry jam, and a red velvet cake.7 The chocolate cake is the most popular order; Lunga attributes this to its balance — "proper cocoa, proper balance, and nothing unnecessary."5
Delivery in the Oslo region is free and covers the area between Drammen and Skedsmokorset.7 The operation serves over 300 companies.5
The company cold-called businesses during summer 2025 and booked meetings with over 100 executives before summer ended.2 Within five months, the Oslo operation had delivered over 1,000 cakes.3 By early 2026, Daymaker reported more than 250 corporate clients, including KPMG and Aker BioMarine.1
Coverage followed in Norwegian outlet Finansavisen, tabloid VG, Danish paper Ekstrabladet, and Swedish paper Aftonbladet, largely because the founders used AI-assisted "vibe coding" to build the product.2
On Christmas Day 2025, the founders applied to Founders Inc., a selective in-person founder residency in San Francisco. They were accepted and began the five-week program in January 2026.4
After arriving in the US, Lindholm and Dieu found that American companies were less interested in automated employee birthday cakes.3 They pivoted to a new use case: personalized "pitch cakes" sent by founders to venture capitalists. One client sent seven cakes — each inscribed with startup details and a funding request — to firms including Andreessen Horowitz, Sequoia Capital, Lightspeed, Better Tomorrow Ventures, and Index Ventures. The founder received five meetings from the seven cakes.3
Daymaker is planning further expansion to New York and San Francisco, with additional US cities listed on its site as coming soon.4
