“We only ship software we would run ourselves — with our own products, we already do.”
Software, Automation and AI That Ships
AI Automation
We map the manual work — quotes, invoices, rosters, reminders — and automate it end to end, so nobody retypes the same data twice.
- > Invoice and payment runs
- > Bookings synced everywhere

AI Agent Development
Agents that do real work inside your tools: draft the reply, prepare the invoice, update the booking — and stop for approval when money is involved.
AI Chatbots & Support Bots
Bots that answer the recurring questions in Dutch and English, and hand over with context.
- What do you want to automate?
- We answer the same ticket questions all week.
- I'll take tier-1 in NL and EN, and pass the rest on with context.
- Let's do it.
AI Consulting & Training
Half a day with your team: where AI actually pays off in your operation, what to leave alone, and what it would cost.


Data & Workflow Automation
Stripe, Shopify, your bookings and your spreadsheets connected, so the numbers match everywhere and month-end stops being a manual job.
- > Stripe to bookkeeping
- > One source of truth

From first call to always on
Every project runs the same way. Four steps to get it live, and two things that never stop once it is.
[ Step - 01 ]Discovery
We pull out as much information as we can, until the scope is crystal clear for both of us.
[ Step - 02 ]Calculate
An estimate as accurate as it gets. You know exactly what it costs to build, and what it costs to maintain.
[ Step - 03 ]Build
In two to four weeks you have a working MVP. Not a demo: something your team actually uses.
[ Step - 04 ]Optimise
Launch is not the finish line. We keep thinking with you about what to improve, and add features how and where you want them.
[ Always on ]Unlimited, always-on support
We keep your projects, apps and agents online. Our own agents watch everything around the clock, so it keeps running smoothly.
[ Always on ]Sidestream Security
Every month we try to hack your project ourselves, from every angle, so the holes are closed before anyone else finds them.
The Stack Behind Our Products
The same stack that runs Ticketbalie, SuperHoreca and Investeren.org in production — not a lab.
Case Studies

Ticketbalie — ticketing for organisers in BE and NL
The ticket platform organisers actually use: sell tickets, scan them at the door, and get paid out automatically through Stripe Connect.
Building Software and AI for
Bars, festivals, gyms, webshops and an aviation group — we build for the industries we already work in every week, not the ones that sound good in a deck.

SidestreamSupercomputerPrivate AI, on our own hardware
We run local AI models on an NVIDIA DGX Spark in our office in Ghent. Your documents, mails and questions never go to a cloud AI provider. They stay with us, and stay private.
Nothing leavesPrompts, files and answers stay on our machine. No cloud AI provider ever sees them.
Models for your workWe pick and tune open models for your task: documents, mail, internal knowledge.
One machine, many usesThe same Spark powers our security checks and the agents that watch your projects.

Work You Can Open in a New Tab
Organisers sell, scan and get paid without us in the loop. We run the platform, the payouts and the support behind it.
Stripe Connect payouts, QR scanning at the door, NL and EN.
Used by organisers in Belgium and the Netherlands.
