Last-mile AI layer

Anthropic, Google and OpenAI built the engine.
We help you cover the last mile.

Our edge: we understand your profession and we master the technical stack. We install the AI employees you're missing to make the difference.

Bubble, a world inside a bubble
01 / Our place in the chain

The engine exists. We build the missing layer.

Anthropic, Google, OpenAI build powerful intelligence engines. Between the engine and your profession, there's a last mile that nobody is building. That's our job.

Intelligence engine
Claude, Gemini, GPT, Mistral...
The raw power. Not yet operational in your day-to-day.
Bubble Invest
The last mile

Your need
An agent that does X in your profession

02 / Our approach

Transparency and precision.

For independents, wealth advisors and small structures who want AI operational without the big-firm fluff.

Bubble on a Japanese pond

Crystal clear, no detours

We tell you upfront what's doable and what isn't. No superfluous costs, no endless audit phases. Three sessions to calibrate together an operational agent that runs on your processes.

An AI agent in its environment

Your new employee that lives at your place, ready to work

No opaque SaaS, no lock-in. Your agent runs on your server or on your machines. You keep control, the code, and the key. You walk away autonomous after three weeks.

03 / Public pricing, no surprises

On continuous watch for three years, we implement on the latest available models. Choose your tempo.

  • We dogfood everything we install 22 agents run at our place every day. We sell you what we use ourselves.
  • We speak your business language Wealth advisors, independents, small structures, all sectors. No tech jargon, no €30k transformation.
