Waimakers Move (July 2026)

On July 21, 2026, Maurice announced he was joining the Waimakers consultancy — pairing his builder skills with a sales-driven partner. He wrote: "PSYCH! @getspinup and I are joining a consultancy 🤩 i can build, but i can't — and more importantly, I don't want to — sell. @woutervhaaften has been building his consultancy Waimakers from the ground up for the past 3 years. the man can sell."^[4]

Jan_Wilmake replied: "Nice to team up with sales. I did the same!" — disclosing that he too had paired his builder profile with a commercial/sales partner, resolving his long-running thinking on commercialisation into a simple answer: partner with someone who sells rather than selling solo (see Career_Plan_2026).^[4]

Connection to Jan

Jan and Maurice interact frequently on X about:

• Cloudflare Workers and MCP implementation issues (specifically OAuth in Cursor)
• AI tooling and building workflows
• The Amsterdam indie hacker scene (Hackadam — recurring hackathon meetups Jan is invited to but often can't attend)

Jan considers Maurice part of his Dutch/Amsterdam builder network. They frequently engage on product launches, code questions, and industry commentary.

Hackadam

Maurice is an organiser or regular participant in HACKADAM — a recurring hacker meetup in Amsterdam. Jan was invited to Hackadam sessions in January 2026 and March 2026, though he couldn't always attend. The format: doors open 9:30, intros 10:30, lunch 12:00, demos 16:30, hangout.^[5]

For the May 28, 2026 edition, Maurice was tagged alongside Jan in @AbnerHout's announcement tweet, confirming his continued involvement in the community.^[6]
