Independent software consultancy & R&D lab

Curious ideas. Real software.

I’m Dan Larsen. Through Techbase, I help businesses develop software, connect systems and make practical use of AI. I also build my own products and explore new ideas in my personal R&D lab.

Some projects are ready to use. Others are still on the workbench.

What I’m exploring

Follow the interesting questions.

Tools for making tools.

With Genny and Runner, I’m exploring how app generation and development workflows can leave code, decisions and review in the developer’s hands.

Room to play.

I’m interested in tools that keep musical ideas editable. A Minor Idea and LaiVE explore different parts of that question, from a short melody to human-led development in Ableton Live.

AI you can inspect.

Through Cortexium, Techbase Bridge and API MCP, I’m exploring practical AI workflows where I can inspect results and keep permissions and important decisions explicit.

Small questions, curious detours.

I like giving a focused question a concrete form. ShowIP answers a network question; RockBot is an experiment in when a robot should listen, reply or stop talking.

Notes from the workbench

Ideas worth thinking through.

Articles and shorter notes on software, useful AI and the tools I’m building.
