We don't sell you software. We build it around your school.
For independent and international schools. Built to give your teachers their time back, and your students English that survives the real world.
Start with a conversationMost school software was built for the masses.
So your school bends to fit it.
You change how you mark, how you report, even how a lesson runs, to suit a platform built for ten thousand schools at once. Which means it was built for none of them. Including yours.
Your teachers keep a quiet stack of spreadsheets to do the one thing it can't.
You rent it by the year. The price climbs. You own nothing.
It was sold to save time. It drains it.
First we understand your school. Then we build.
We ask your teachers how the week actually works. What eats the hours that should be theirs. Then we build around what we find.
It starts with a conversation, not a contract.
See how we workWe ask every teacher. No meeting required.
A few questions each one answers when they have a moment. So we hear how the week really works, from everyone.
We find what eats the hours
Not the teaching. Everything around it: the busywork that quietly takes the evenings.
We build around it
Not a template with your logo on it. Software made to fit the school you already are.
You keep teaching
The software is what changes; not your teaching!
Two things we build toward: every time.
Give teachers their evenings back.
Every assignment is a cycle: design it, print it, hand it out, chase it, collect it, mark it, feed back. Then again tomorrow.
We build that whole cycle into one place. The teacher sets the assignment; the software builds it, marks it, and drafts the feedback, in the teacher's own voice and house style, for them to approve.
The software does the seven steps. The teacher keeps the one that matters: the judgment.
An evening back. Every night.
Every night!
Give students English that survives the real world.
Most software tells you a student scored 7 out of 10. It can't tell you they froze when a stranger asked them a question.
We build for the second thing. Tools that get students speaking, not just sitting tests. And a dashboard that tracks the English they can actually use. It shows progress honestly, including the weeks a student is stuck.
So you see real growth, not a flattering number. And meeting the national standard stops being a year-end scramble. It becomes the floor your students already stand on.
English they keep. Long after the test.
The cycle and the dashboard are two examples. Your school may need something different.
What we could build for you
The people
We built this for ourselves first.
We've taught in Hanoi for years. Between us, more than fifteen, and plenty more years in other locations before that. We know the cycle in this page because we lived it: the constant marking pile, the Sunday reports, the evenings that belonged to the job instead of to us.
So we tried the apps. Most of them. None did what we actually needed, and most did ten or more things we didn't.
In the end we stopped looking and built our own. Not software for every teacher in the world. Software for us, that did exactly what our teaching (and our students) needed and nothing it didn't.
Then a thought: we can't be the only ones.
If you're where we were before we built it, that's who Blue One Hundred is for.
We look forward to helping your school.

Questions schools ask
Every build is bespoke, so there is no fixed price list. The cost depends on what your school actually needs, which we work out together before anything is built. You pay once and own the software outright. After that, you choose: we manage it for a modest, flat monthly fee per student, or we train your own staff to run it. You get a clear, fixed quote before you commit to anything.
Then you would still have everything. When we build your software, your school owns it outright. It is yours to keep and use for as long as you like. (English, and the teaching of it, does not change much. Software built well today still works in ten years.) You also choose how it is run: we can manage it for you, or we train someone on your staff to manage it. Either way, it is yours, and it does not stop working if we do.
Faster than a full IT project, because we are not building for ten thousand schools, only for yours. We start by understanding how your school works, then build around what we find and what you want. You get a realistic timeline before we begin, and we build in stages, so you see things working early rather than waiting for one big launch.
Yes, and not as a box-ticking exercise. We build tools that raise the English students can actually use, and meeting Decision 2371 follows from doing that well, rather than being bolted on afterwards. We design your reporting around the standard, so you can show progress clearly, to inspectors and to parents.
Your teachers stay in charge. The software drafts feedback in each teacher's own voice and house style, which they set in advance, and nothing reaches a student until the teacher has approved it. It is there to save the hour of writing, not to replace the teacher's judgment.
We work around them, not against them. Part of understanding your school is seeing what already works and what does not. We build to sit alongside what you want to keep, and we replace only what is holding your teachers back. You decide what stays.
Yes. Your software runs on standard, well-supported technology, and your data belongs to your school, not to us. We do not sell it or share it, and you control who can see what. We are happy to walk your team through exactly how it is stored and protected before you commit.
Not at all. Because we build around how your teachers already work, the software fits their current routine instead of forcing a new one. We keep it simple, and we train your staff so they are confident from the first day. If a tool needs a thick manual, then we have built it wrong.
No. We do not touch the teaching. We take the cycle around it, the marking, the chasing, the reporting, so your teachers spend more time teaching, not less. The software does the busywork. The teacher does the teaching.
Because off-the-shelf software was built for the average of ten thousand schools, so it fits none of them exactly, and your teachers end up working around its gaps. Bespoke software fits your school, so there are no gaps to work around. And you own it, instead of renting it forever.
You own it. Outright. Most school software is rented: you pay every month, forever, and own nothing. With us, you pay once and the software is yours. An asset, not a subscription.
Of course. We build in stages. Many schools start with the one thing causing the most pain, see it working, and add more once they trust it. You are never forced to build everything at once.
Yes. We build bilingual by default, because your school, your teachers, and your parents all work in both. Each person uses it in the language they are most comfortable in.
Yes. If you choose to have us manage your software, support is included. If you choose to run it yourselves, we train your staff to do so and stay available if you need us. You are not left on your own at launch.
Yes. We work with independent and international schools, and with English centres. If your organisation teaches English and controls its own decisions, we can build around the way you work.
They can, if your school wants that. We can build a parent dashboard that shows a child's progress honestly and clearly. It is optional, and you control exactly what parents see and what they do not.
That is normal, and expected. Schools change, and software should change with them. We build so that changes are straightforward. How they are handled depends on whether we manage your software or your own team does.
Less than you might fear. The heaviest part is early: a conversation with your teachers about how the week really works. After that, we do the building. We check in at the right moments, but we do not tie up your staff for weeks.
The ones you already have. It works on school computers, teachers' laptops, and phones, so no one needs to buy new hardware. We build for what your staff and your students use now, and will in the future.
We build for the range in a real classroom, not for an average student who does not exist. Work can be set at different levels at once, so a student who is behind and a student who is ahead are both met where they are.
In the end, it's yours.
Whatever we build for your school, you own it. Outright. Not rented, not leased, not held hostage to a monthly fee you can never stop paying. An asset your school keeps, and uses, for as long as you like.
We're two teachers who got tired of software built for everyone but us. So we built our own, and now we build it for schools like yours.
If your teachers are drowning and your students deserve English that lasts, let's talk. No pitch, no pressure. Just a conversation about your school.
