Udo Kempen — First In.

How I got here

I've spent my whole life trying to get to the future before everyone else.

It started in 1983, in a suburb of Dortmund, Germany. While my peers were figuring out what they wanted to be, I left school to open one of Germany's first video rental shops. I hooked a 300-baud acoustic coupler up to my store's cash register to sync sales data. That was it for me. I knew what I wanted to do.

William Gibson's Neuromancer wasn't fiction to me. It was a preview. Electronic communication was going to eat the world, and I wanted to be part of it.

Mailboxes, Datex-P, UUCP, BTX, the birth of the World Wide Web. I was there for all of it. Built the infrastructure, invented payment systems, hired people smarter than me, made every mistake you can make. Most of them twice.

Wins, scars & timing

1983 - 1986

The Video Store & the 300-Baud Moment

Founder · One of Germany's First Video Rentals

Left school to open one of Germany's first video rental shops in Dortmund. Right time, right place. Too much success, too soon for a 17-year-old who wasn't even legally allowed to enter his own shop. Used a 300-baud acoustic coupler to sync sales data, and from that moment I was hooked. Read Gibson's Neuromancer and saw not fiction, but a preview of where everything was heading.

1986

Teledata BTX GmbH

Founder & Managing Director · 10 Employees · Dortmund

Built BTX (Bildschirmtext) and UUCP online services when most Germans hadn't heard of a modem. Ran some of Germany's earliest online commercial ventures, selling things on screens years before anyone thought that was a real business. *timecd# was ahead of its time. Amazon proved the concept years later.

1997

Comtron Network Service GmbH

Founder & Managing Director · 25 Employees · Dortmund

Grew an Internet Service Provider from nothing to 25 employees. We were Dortmund's early internet plumbing. With Toni Saretzki, I co-invented the 0190-Dialer, Germany's first premium-rate micropayment system for the internet. It became the standard billing method for digital content across German-speaking Europe. Then bad actors abused it into the ground. Tools don't care who uses them. I still miss you Toni.

Late 90s

E-Sports & Tobias Lütke

E-Sports Pioneer · One of Europe's First Commercial Clans

Co-founded Ocrana, one of Europe's first commercial esports clans. Quake deathmatches, Ultima Online raids, late-night coding sessions with a young German programmer named Tobias Lütke. I hired Tobi for his programming skills and watched him code his very first online shop: a snowboard store. If you read this Tobi: Hail Vendor, buy, Guards! He left Comtron, went to Canada, and that snowboard shop became Shopify.

Late 90s

The Shop I Closed Too Early

A Lesson in Timing

I still ran an internet video and CD shop until German law punished me for selling a horror movie, and out of frustration, I shut it all down. Jeff Bezos built exactly that business from a garage. One of my biggest mistakes. I've made plenty.

2000

The Trading Years

Futures Trader · The Hardest Lesson

Walked away from the internet to trade futures. Lost a lot of money. Then made a lot of money. Then lost everything that actually mattered. The emotional toll, addiction, a proper midlife crisis. No technical skill prepares you for what markets do to your head. Eventually I came back to what I actually know how to do: building things online.

2007

wellenreiter consult GmbH

Managing Director & Digital Strategist · Dortmund

Brought digital marketing to Germany's banking sector. SEO, email campaigns, social media for Sparkassen. These institutions were still printing brochures. Nobody was saying "digital transformation" yet.

2014

The Quiet Life That Wasn't

Independent · Mallorca · WordPress · SEM · Linux · AI

Moved to Spain for a quieter life. Built WordPress sites, managed Linux servers, ran search campaigns. Then AI showed up. I'd been waiting for it.

Core Expertise

001

AI Integration & Automation

I build AI support systems, workflow automation, and tools that actually replace manual work. These are production systems running in regulated industries, not demos.

002

Digital Strategy & Growth

SEO, SEM, GEO, market positioning. Twenty years of this, from German banking institutions to SaaS platforms. I care about what the numbers say, not what the slide deck looks like.

003

High-Risk Payment & Compliance

25 years of processing payments where others can't or won't. Merchant-of-record solutions, KYC/AML, payment infrastructure for industries that Stripe and PayPal refuse to touch.

004

Infrastructure & Ops

Linux servers, Docker, NGINX, security hardening, mail systems, databases. If it runs on a server, I've probably broken it and fixed it.

005

Payment Systems & Monetization

I invented Germany's first internet micropayment system. Now I build e-commerce funnels. I think about how things make money, not just how they work.

006

Multilingual Reach

Native German. Fluent English and Spanish. I've been working across markets and languages since before the web had a language selector.

The Next Chapter

When AI arrived, I didn't have to adapt.
I'd spent forty years getting ready.

I've been too early. I've been too late. I shut down a business that Amazon turned into a trillion-dollar empire. I watched a kid I hired code a snowboard shop that became Shopify. Forty years of getting it right and getting it wrong taught me one thing: timing matters more than anything else.

The technology is never the hard part. Knowing when to move is. That instinct comes from decades of being in the room when things changed.

If you're thinking about AI, the time is now. Not next quarter. Not after your competitors figure it out first.

I work with clients who get that. The right strategy, done well, beats a hundred tools.

What I'm Building Now

Proving It Today

History is nice. What matters is what I'm doing now.

AI · Customer Support · GEO

TicketPay

Germany's leading ticketing platform. I'm working on AI-driven customer support, smarter web development workflows, and GEO optimization so their platform shows up when AI systems answer questions, not just when humans search Google.

AI Infrastructure · GDPR · Web Dev

CWS-Media

I'm building AI infrastructure that lets us ship high-quality, GDPR-compliant websites for small businesses much faster and cheaper than before.

Local · Mallorca · Digital Growth

Local Businesses

I also work with businesses across Mallorca. Same approach, smaller scale.
