SEBASTIAN DIEMER / IDEAS → REALITY

I had an idea.
Now it has engines.

For years, I needed a team to build what was in my head. Now I talk it through, put agents to work, and keep refining. My voice. My taste. Rosi on quality control.

Why this changes everything for me ↗
FROM THE ENGINE ROOM

Thoughts, made tangible.

—lines of source code
—source files
How these are counted ·

Measured source lines, including HTML and CSS, from four deployed project codebases. Identical files count once; dependencies, archives, configuration and minified files are excluded. These are not productivity or AI-authorship metrics. Refreshed on visits, at most once every 15 minutes. No AI calls.

From “what if” to here it is.

YOUR THOUGHT. OUR NEXT BUILD?

“Diemer,
let’s build
something.”

A tool that ought to exist. A website with a mind of its own. A project you can’t stop thinking about. I’m up for building it together — or showing you how to get started with AI yourself.

your idea + my brain + AI + ♥

ROSI / IDEAS SECRETARY

Short pitch.
Big thinking.

“Hi, I’m Rosi. Diemer has a lot on his plate. I have the bigger ears. Tell me in up to 30 seconds what you want to build and why it should exist.”

  1. Record, then listen back.
  2. Add your name and email, with an optional phone number.
  3. Approve it. Your idea is transcribed, organised and sent to Diemer.

Please enable JavaScript to record. You can also email me directly.

MY TAKE ON AI

AI brings the thrust.
Where are you going?

I spent years collecting ideas. Now I can build them. A few thoughts on creativity, the care that makes a product good, and how long we’ll stay in the pilot’s seat. Rosi probably has the best plan.

The full story. Or 90 seconds in your ears. ↗
