Stop Scheduling. Start Teaching.
Autonomous AI scheduling infrastructure for schools globally, starting in Europe. Instant AI scheduling, live substitute matching, WhatsApp-first alerts, and a modern control plane that scales from complex European stacks like Magister and Somtoday to US K-12 districts worldwide.
Who builds this

- HAVO 5 · Amsterdam → San Francisco
School timetables still run on stress and overnight compute
Every week, schedulers lose hours to work that software should finish in seconds, while teachers and students feel the chaos.
4–12h
Typical wait per full run
Slow generation
A basic timetable can take hours or a full night to calculate. Every tweak means waiting again.
30–90m
Per sick-day scramble
Manual cover chaos
Sick leave triggers calls, emails, and guesswork. Coverage is late and uneven.
High
Friction for the whole school
Gaps and burnout
Students hate free periods. Teachers burn out on brutal day shapes. Parents notice both.
AcadeStack: AI that runs the timetable so people can teach
One control plane for generation, daily disruptions, substitutes, and notifications, built for speed, fairness, and wellbeing.
Step 1
Compute in seconds
AI recomputes the timetable live so schedulers see impact before they commit a single move.
Step 2
Operate in real time
Sick leave, room issues, and transit delays trigger automatic proposals and alerts.
Step 3
Protect people
No-gap student rules and sustainable teacher loads are hard constraints, not afterthoughts.
Raw UI from the product we are shipping
Not concept art. The same control surfaces schools use: sub-10s recompute and WhatsApp-first disruption alerts.

Why schools actually buy this
EdTech dies in board procurement. We skip the slow front door and enter through the person who feels the pain every Monday.
- 01
Target the frustrated roostermaker
Win one innovative scheduler or teacher who already fights spreadsheets, sick-day calls, and overnight runs. Not the full board. One champion.
- 02
Prove value in one week
Show hours returned on their real constraints: live recompute, cover matching, fewer Monday fires. Proof beats pitch decks.
- 03
Spread via peer networks and WhatsApp
Champions forward wins into WhatsApp groups and peer schools. Land with one user. Expand across the board once the timetable already works.
From school chaos to global infrastructure
Europe is hard mode on purpose. Win the complex market first, then expand where systems are simpler.

Build + prove in Europe
Ship the autonomous layer on Magister/Somtoday-class stacks. Champion-led pilots. Measure hours returned.
- Next
Paid European schools
Convert champions into paid schools. Harden integrations. Hire an ops/sales co-founder for distribution.
- SF
San Francisco base
Operate from SF. Raise velocity with YC-caliber network. Keep product ownership with the founding builder.
- US
US K-12 expansion
Take the same control plane into US districts. Simpler semester systems after Europe's dense weekly grids.

I sat in the timetable chaos. Then I started building the fix.
I'm Julian Schoonhoven. I'm 15. I write the code myself. Here's the real story, no corporate gloss.
Where it started
I'm still in secondary school in Amsterdam. Every week I watch the same machine fail: a teacher calls in sick, someone opens a spreadsheet, phones start ringing, and the timetable falls apart before first period. I felt that friction as a student who loses lessons to gaps and last-minute room changes. One evening after rowing practice, I stopped complaining and opened a code editor. AcadeStack began as a personal refusal to accept that schools should still wait overnight for a basic recompute.
Why now
This only became possible in the last couple of years. Older timetable packs like Zermelo and Somtoday are legacy software: batch-era architecture, overnight compute, and UIs glued onto yesterday's constraints. They were never built for modern LLM-assisted constraint solving, real-time cloud recompute, or WhatsApp-native ops. The AI wave finally makes a live autonomous layer possible. Incumbents can't rewrite that stack overnight. We can.
The secret most vendors miss
Schools don't need another prettier calendar. They need an autonomous layer on top of complex legacy stacks. Europe is the hard mode: Magister, Somtoday, dense weekly grids, and brutal disruption ops. That complexity is our moat. If AcadeStack wins here, US K-12 districts with simpler semester systems become the expansion market, not the proving ground. The hard problem isn't drawing a grid. It's operating the day when reality breaks the plan.
Solo founder, on purpose
Yes, I'm 15 and solo. That is a risk. I say it out loud. I am not looking for a co-founder to write the tech. I already do that myself, fast. I am looking for an operational and sales powerhouse who wants to conquer schools once we are in San Francisco. Product velocity stays with me. Distribution at scale is the teammate I want next.
Customer obsession
Before this site went live, I talked to schedulers, teachers, and school operators about sick-day cover, Magister/Somtoday friction, and what 'good' looks like on a Monday morning. Every feature on this page maps to a sentence someone said out loud. If you run a school or a district ops team, talk to me directly. I still take the calls.
What is still hard
Distribution at board level is still the brutal part of EdTech. That is why bottom-up GTM comes first. Clean integrations across messy European exports remain real work. I'm not pretending we have product-market fit locked. We're early, fast, and listening.
10-year north star
Prove the hardest market first: European legacy scheduling. Then take the same autonomous control plane into US K-12 and every district still stuck on overnight compute. Europe is the gym. The US is the stadium. Billion-dollar school operations infrastructure, not a lifestyle tool for one country.
Who builds it
- I write the product, the scheduling logic, and this website myself. No outsourced engineering team. No agency owning the vision.
- Nights and weekends after school and training. If nobody funded this, I'd still ship it, because the problem sits in my own school week.
- Idea to live demo measured in days, not quarters. Velocity is how we work.
Facts, not fluff
- Dutch National Champion, Junior Men's 16 Quadruple Sculls (KNRB, 2026)
- International winner, MU17 2x, Ghent International May Regatta
