We take care of room allocation at your student residence.

Few things shape a student's year as much as their roommate. We get to know every resident through a survey on habits, schedules and personality, and pair them with the roommate they fit best. You save weeks of manual work and keep the final say on every pair.

  • Double rooms: we prevent problems between roommates.
  • Single rooms: we prevent problems with the neighbours.
Shall we run a trial with your residents?

The problem we solve

Deciding who shares a room with whom takes the team weeks, and even then the decision is made blind: degree, home region and age say nothing about whether two people will get on. We know what does. We measure it across twenty dimensions and allocate an entire building in seconds.

What happens when rooms are allocated by hand

6.7/10

is the average score students give the roommate their residence assigned them.

But the average doesn't tell the whole story: more than 1 in 4 give a score below 5.

54%

of students have had a conflict or an argument with the roommate they were given.

And in half of those cases, what they do to fix it doesn't work.

What happens to the student

  1. They arrive in September not knowing who they'll share a room with
  2. and end up with someone on a different schedule
  3. who keeps them awake on weeknights
  4. and it ends up showing in their grades

And that's only the part you can see. None of the students we interviewed asked the residence management for help: they talked it over with their roommate, let it go or moved on their own. Nobody at reception ever knew there was a problem.

And what happens to the residence

  1. A complaint in October
  2. that forces a room change, and moving a third person
  3. that ends in a place that isn't renewed
  4. and in a review that damages your residence's reputation

Filling a place again costs more than keeping it: marketing, viewings, paperwork. Add the more than 100 hours a year spent making the allocation work, and what looks like an August task is costing you money all year round.

I had to ask for a room change after six months. With my second roommate there were problems too, because she didn't clean.
Age 20 · double room
I'd walk into the room and the smell was unbearable. My roommate had no hygiene at all. The following year I left the residence.
Age 20 · double room
We were very different and had a big fight. I had to move out of the residence.
Age 21 · double room
I had to move my mattress into a friend's room and live with them.
Age 20 · double room
He studied architecture and got up early to make models, sometimes at night too, and I couldn't sleep properly.
Age 20 · double room
I'd come back to the room and there'd be people in there drinking.
Age 21 · double room
I ended up with someone who didn't talk to anyone and never left the room. We never got on, and I spent the whole year without feeling comfortable in my own room.
Age 19 · double room
If I'd had a good experience, I'd still be in a double room and living at the residence.
Age 22 · double room
They don't tell you who you'll be sharing with until you get to the room.
Age 23 · two years in a residence
I was very lucky with my roommate, but I did know people who had problems.
Age 19 · double room

The biggest fear of anyone booking a shared room is not knowing who they'll live with. Being the residence that can answer that is a competitive advantage, and with WeMates you have it before other residences do. Don't get left behind.

How does our product work?

From the signed contract to the assigned room. Click any stage to see what happens behind it and what you get from it.

You upload your list with what each student has booked

You upload your list as a CSV or Excel file with the bookings and their room type, and mark who is returning or already has a room assigned, and who is coming with a roommate of their choice. The room inventory is loaded only once, when the account is set up.

What you get

Nothing to migrate. Your team keeps its tools and its process. WeMates only decides who goes with whom and in which room, based on how well they fit.

The students screen of the dashboard: generated booking codes, room type per student and survey status.

We've been through this too. In many residences the walls are thin and you hear everything, so we aim to give neighbouring rooms, double or single, similar schedules and noise habits.

What we measure, and why

The survey doesn't ask about tastes. Each dimension comes from a named model, and it is there because it predicts a specific source of friction in shared living.

Cleanliness is one of the things people who live together clash over most, and standards vary a lot from one person to the next. That's why we don't ask how people see themselves. We ask about concrete habits.

“How often do you clean your space?” Measures actual behaviour, not self-perception.
“At the end of a long day of classes or studying, what usually happens with your things when you arrive at your room?” Measures a different habit from the first question: a deep clean every so often is one thing, tidying up every day is another.
Two students on the same cleaning-frequency scale, far apart from each other: a possible-conflict warning. Cleaning frequency rarely daily Student 1 Student 2 ! possible conflict
A big gap in this habit between two people who are going to share a room is a sign of possible conflict.

For some people the room is a private sanctuary, for others a social club: everyone needs a different amount of people and noise around them. The problem starts when the two see it differently.

“What is your opinion on having guests in your room?” Decides whether the room is a closed sanctuary or an open door.
“How often do you listen to music, watch TV, or listen to podcasts at home?” Noise carries even when each person is in their own room.
Two ways of seeing the room: a private sanctuary versus a space open to visitors. Sanctuary Open house The same room, two different ideas of what it is for
What matters is whether the two of them see the room in the same way, however sociable each one is.

An early bird and a night owl clash at very specific moments: one wants to sleep while the other still has the light on, or one gets up very early and wakes the other. That broken rest is often behind conflicts in the room and, in the most serious cases, behind a request to move.

“Are you an early bird or a night owl?” If one is a morning person and the other a night person, their sleeping hours don't line up.
“Do you prefer studying/working in silence or with some background noise?” How each one needs to concentrate, which matters even more at exam time.
Two misaligned sleep windows: the stretches where one sleeps and the other is awake are where the friction is. Early bird Night owl 18:00 00:00 06:00 12:00 one sleeps the other sleeps
The two shaded areas are the hours when one is asleep and the other is up and about. That is where rest gets broken.

Day-to-day routines and the use of shared things: smoking, food in the room, weekends away. Small details that, repeated two hundred times, stop being small.

“What is your preference or tolerance regarding smoking?” Here, being similar isn't enough: either they agree or they don't. Someone who can't stand the smell is bothered just as much if their roommate smokes only a little.
A smoking-tolerance scale with a wall in the middle: between smoking and not tolerating smoke there is no middle ground. no middle ground here smokes daily can't stand smoke and goes out on the balcony not even on clothes
The other dimensions allow for some difference. Smoking doesn't: it only works if both agree.

The way each person handles a disagreement matters as much as what the disagreement is about. That's why we take each person's conflict style into account, so that two very different ways of dealing with it don't end up colliding.

“How do you usually react when a disagreement arises with someone (e.g., over noise or cleaning)?” Thomas-Kilmann model: compete, accommodate, avoid or compromise.
“What is your stance on sharing personal belongings?” Territorial or communal: “what's mine is mine” or “what's mine is yours”.
Thomas-Kilmann grid with the five conflict styles: the further apart two styles are, the more likely the friction. assertive cooperative Competes Collaborates Compromises Accommodates Avoids the further apart, the more friction
The further apart two people's styles are, the harder it is to settle a clash between them.

5 open questions to tell us who you are

The only ones with complete freedom to talk about what they love and what they couldn't stand in a roommate, beyond their habits.

  • What would your perfect Sunday at the residence look like?
  • What is the one thing you couldn't stand your roommate doing?
  • What kind of relationship do you expect to have with your roommate?
  • What do you need from your environment during exam season?
  • What hobby or habit should your roommate know about?

Salamanca · 2026-27 academic year

The year that was allocated in an instant

The Colegio Mayor de Oviedo, part of the University of Salamanca, already had who gets in settled: the university awards places by academic grades with a system of its own. What was still done by hand was deciding who shares a room with whom, using the only clues available: same degree, same home province, similar age.

In July 2026 WeMates did that allocation. 278 students, an entire building, a full academic year. The result was 74 double rooms, which means 148 people paired, and 130 single rooms. All 278, with nobody left without a place.

The entire allocation, all 278 of them, was calculated in under 10 seconds.

74double rooms formed
  • Returning residents kept the same room
  • Those who arrived with a roommate of their choice, whether siblings, friends or people from the previous year, stayed together
  • The Colegio Mayor's rule of pairing within the same gender was respected
Sometimes you put two people together and it goes fine, they get on politely, and during the year they don't ask for a room change or have any problems. But maybe, if they had been matched with richer data, you would have found a better person for each of them. And maybe you'd get two friends out of those roommates.

This is the problem WeMates solves.

The academic year is under way

At the Colegio Mayor, room changes cluster in the first fifteen days of each semester. We have asked them for that figure so we can compare it with the previous year's.

We will publish it here as soon as we have it, whatever it shows.

About us

We are Óscar Grau and José Pablo del Moral. We started WeMates in 2024, while we were students at Universitat Ramon Llull, after seeing up close what spending a whole year next to the wrong person does to someone.

What made us look beyond our own experience was a friend. He lived in a double room in a beautiful, well-run residence, the kind that gets shown off proudly on move-in day. And every time we went to see him, the room smelled bad. When he talked about that year he never mentioned the building. He talked about the person sleeping two metres from his bed. The following year he left the residence.

We started asking around and kept finding the same thing. When people have a bad year, it is almost never the residence. It is who they were placed with. And hardly anyone tells reception. We are still at it for the same reason we started: so that the student who arrives in September doesn't have to endure the year, and you don't have to fix it in October.
