Joakim Runeberg
Full‑stack product engineer and ex‑designer. Twenty years across design and development, usually wearing both hats at once — and a firm believer in prototyping, data‑informed decisions and a culture of healthy experimentation. Currently building things at Teamspective, an AI‑native leadership enablement platform. Previously at Thingtesting, Project 5/5, Panacea and Reaktor.

Writing
Notes & essays
Gimmicks get tried. Useful tools get used.
AI is being added to everything. The only question that matters is whether it becomes part of how people actually work.
Six months in, without the day‑one post
What the first half‑year at Teamspective actually looked like, instead of the “humbled and energized” announcement.
Now
What I'm up to
- Building things at Teamspective — design, full-stack, growth and product, depending on the day.
- Making the case that AI features should be used, not just shipped.
- Writing a cross-platform game engine from scratch in C++, with both OpenGL and Vulkan backends.
- Making artisanal gelato (stabilisers and weird ingredients welcome) and baking sourdough.
