AI is the means, bottom-line results the goal. We build your own AI system that lets your team get three times as much done. No new software, no subscription: yours from day one.
Pretrain systems are already live at 10+ businesses






In 60 minutes we walk through how things run today and where the hours go.
60 minutesEmail, calendar, quoting software, accounting. Tested on your own enquiries and orders, then live. No migration, no new software.
Live within 8 weeksLess manual work, faster follow-up, paid sooner. Your team steers the system itself, we stay on only if you want us to.
OngoingRetyping, drafting quotes, processing receipts and chasing is done by the system. Your team decides, approves and talks to customers.
Lead followed up within the hour, quote out the same day, invoice right after delivery. From enquiry to paid in fewer days.
More enquiries, quotes and projects with the same people. More work no longer means more hands.



Your own server, your own data, source code that is yours. If you stop working with us, it simply keeps running. Maintenance is optional and cancellable monthly.

I have been building AI solutions for businesses since December 2022, when ChatGPT had just come out. I spent two years as a growth engineer at coaches.com, where I helped realise tens of millions in annual revenue growth with AI. I founded Pretrain to help more businesses realise that growth.

Five years as a quality engineer in Brainport, at high-tech manufacturers. There I set up systems and processes that prevented errors whose cost could run into the millions. At Pretrain I use that experience to make your systems rock solid, so you can grow on them without worry.

Five years of experience with AI solutions in the water sector. At Pretrain, Timo translates your work into what the system has to deliver and guards that during the build: outcomes first, AI is the means to get there.
Businesses of 10 to 50 people where the owner works in the business and where enquiries, quotes, orders and receipts pass through the same hands every week. Installers, contractors, wholesalers, rental and property management: the cases above show what that looks like.
Yes. The agents work in your email, calendar, CRM and accounting. Nobody has to program anything or learn a new package. Whoever can make a quote today can approve a quote tomorrow.
We build into what you already run: the calculation package, the accounting, the planning. Excel stays Excel as long as it works. Where an Excel list is really an overview everyone needs to see, we replace it with a screen that updates itself.
A system that runs on your own server, with your own data and your own login. The source code is yours. It keeps running without us, and you can continue with it yourself or with another partner.
Decide, handle exceptions and talk to customers. The retyping, chasing, looking up and reminding is done by the system. You approve where it matters, the rest runs.
Before we start we measure how long a quote, an order or a follow-up takes today, and we measure again afterwards. Those are the numbers in our cases. Every step the system takes is logged, so everything can be traced.
A one-off fee for the build. The system is yours after that. If you want, we maintain it for a fixed monthly fee, cancellable monthly: server, updates, monitoring and small changes such as new prices or rules. When better AI models come out, we connect them at no extra cost.
A 60-minute intake, then a few hours a week to review and give feedback on what the system produces. No migration, no days of workshops. Your work carries on as usual.
The first agent runs on your own work within a few weeks. The full programme, from intake to a system your team runs itself, takes 8 weeks.
Amounts, VAT and customer details come from your own systems, not from the language model. Anything that deviates, such as a different price, a new bank account or a cancellation, the system first puts to you with its recommendation. If it does not understand something, it asks once; we build the answer in.
The system is yours and keeps running. Documentation and handover are part of the programme, so you or another partner can carry on. Maintenance is cancellable monthly.
On your own server, in your own systems. The system works with its own login and only the permissions the task needs. No copy of your administration with us. You can revoke access at any time.
