AI BUILDER · TRIATHLETE · FATHER · BUILT BEEKEEPER TO 7M USERS

I build AI systems. For fun, for business, and to run my own life.

Twelve agents, two data lakes, one rule: no slides — only things that survive contact with reality. Built Beekeeper to 7M frontline users and an exit. Now back building with AI.

WHAT I AM BUILDING

My Workbench.

Every system on this workbench has a story that didn't fit on the card — what I tried first, what broke, and the thing I only understood afterwards.

The Swarm

LIVE

My mornings run without me. Twelve agents wake at 07:30, read my body, my money, my emails and my calendar, and leave one brief behind. Five subscriptions died so this could live — USD 3,720 a year, cancelled.

MoneyLake

LIVE

Ninety-seven accounts, five currencies and eleven years of accounting, moved off a $750/year subscription and into a database I own — reconciled to the cent.

Building Notes:

I'm writing them as I go, one at a time.

HOW I BUILD

Four rules.

No slides.

If it hasn't run in production against my real life, it's an opinion.

Never trust the output.

AI is amazing. But you can't trust that what comes back is exactly what you asked for. No testing, no releasing.

Automate the boring, keep the judgment.

The agents decide what I look at. I decide what I do. That line never moves.

Own the data.

Every system here writes to something I control. Subscriptions end. Companies pivot. Fourteen years of my own data doesn't.

STORY

The long race.

I'm a chemical engineer who ended up building and leading a software company. Fourteen years of Beekeeper, from an idea to 7M frontline users and an exit. That's a long race — and a long race teaches you fast what actually works and what only sounded good in the meeting.

Now I'm on the other side of it. No company to run — on purpose. A bench full of systems I built for myself, a training plan I engineer like a product, and the time to work out what sustains this rather than what replaces it. This page is the honest log — including the parts that broke.

WANNA BUILD TOGETHER

Three ways in.

Not sure where AI pays back first?

00 — ASSESS

Start with the assessment. One 45-minute conversation, a written report five working days later: the tools to switch on this month, the one process to fix first, and the hours a week it returns. Fixed price, CHF 990 — credited in full if we keep going.

SEE THE ASSESSMENT →

Got a problem nobody can crack?

01 — BUILD

Or a crazy vision you've always wanted to make real? Those are my favourite. If you're sitting on something everyone calls unsolvable and you'd rather build than buy, let's talk. I take on two or three at a time, hands on the keyboard, building next to your team — not writing a deck about what they should do.

TELL ME THE PROBLEM →

Want your team building with AI?

02 — TRAIN

Working sessions, not a slide deck about AI. We bring your real problem into the room, pull it apart, and rebuild it live. Your people walk out having built something — not having watched me build something.

BOOK A SESSION →

Need someone on your stage?

03 — SPEAK

Scaling to 7M frontline users. What the exit didn't change. And what happens when you build AI systems as an entrepreneur and operator. English, German or Spanish — whichever the room speaks.

Or train with me one to one

1:1

Personal AI training for CEOs and board members: four to eight sessions built around your role, your decisions and your calendar. No group, no fixed date, no full day blocked out.

REACH

Easiest way in.

Just email me at cris@grossmann.ai. I read every one myself.
