Daymaker: cakes as sales outreach, almost $100K invoiced in a month, platform vibe coded with Lovable by a 20-year-old
A platform that sends custom cakes made by local bakeries and hand-delivers them, first for company birthdays and now as 'cold caking' sales outreach with your pitch or a QR code on the cake.

“Last month we invoiced $10k in cakes This month we’re invoicing almost $100k beacuse coldcaking blew up.”
Editor's note: William Lindholm is a 20-year-old Norwegian founder who says he can't code. Gründerszene reports he built the software with Lovable, including 'the complete backend', coding at night and delivering cakes by day, and Lovable's CEO has posted that William used Lovable to build Daymaker. Revenue is mostly cakes and delivery, made by partner bakeries (first a pastry chef in Oslo), so this is a software-run service rather than pure software. The company moved from Oslo to San Francisco; its site now sells a 'guaranteed meetings' package (about 130 hand-delivered cakes, money back if fewer than 20 meetings), a self-serve option, automatic client birthdays and a cakeMCP for AI agents.
How they got customers
In summer 2025 he and co-founder Simon Dieu cold called more than 100 executives, including at KPMG, to sell automated office birthday cakes. In San Francisco he switched to 'cold caking': sending a prospect a custom cake with a pitch or QR code on it instead of another cold email, and posting about it on X, where his March 2026 revenue post was viewed about 400,000 times.
