Subletting with a business match
Empty square metres cost you money. The right neighbour makes you money.
We fill your unused office and warehouse space with a company you do business with: a customer, a supplier or a partner. Lower costs, new revenue and shorter supply lines, under one roof.
Building owners never pay. Fixed fees, no percentages.
The problem
You pay every day for space nobody uses
41%
average daily occupancy of Dutch offices
3.3M m²
of leased office space in the Netherlands is not being used
100%
of that space is still paid for, every month

The opportunity
An empty room costs rent. The right company in that room is worth far more.
Most subletting stops at covering costs. We go further: we find the neighbour who grows your business.
Your customer next door
When your customer works down the corridor, the next project starts over coffee. Introductions through your neighbour can grow your customer base substantially.
Your supplier in-house
No shipping, no waiting. When the stock is downstairs, lead time drops from days to the same day, and purchasing and logistics costs fall with it.
Your partner under one roof
Combine offers, share clients and win together what neither of you could win alone.
How it works
Three steps to the right neighbour
Tell us about your space
Five minutes. Tell us what you have and which companies you would love to work with. The calculator shows what it is worth straight away.
We find your match
A person, not an algorithm, looks for your customer, supplier or partner, and arranges your landlord's consent with you.
Your new neighbour moves in
You earn rent on space you were not using and gain a business relationship. If your neighbour leaves, we find a new one at no cost.
People first
We introduce people, not square metres
A good neighbour is someone you like to bump into at the coffee machine and want to do business with. That is why every match is reviewed by hand. Founder Frederic Marcillaud personally looks at every introduction before anyone moves in.
And once you are neighbours, it does not stop there: you join a network of companies that share buildings, ideas and customers.

Who it's for
Everyone in the building wins
Building owners
Keep your tenant. Fill your building.
A tenant with too much space no longer needs to leave. You keep your income, your building becomes a business community, and you pay nothing.
For building ownersSpace to spare
Turn idle space into a business asset
Stop paying for space you do not use. We find a neighbour who pays rent and does business with you. Fixed fee, never more than €500 a month.

Frequently asked questions
Can I simply sublet my space?+
You need your landlord's written consent. That is why we involve the building owner from day one, and give you a ready-made consent request.
What does the building owner pay?+
Nothing. The owner keeps the tenant and gets a fuller, livelier building. Owners who bring in tenants can earn as a partner.
What if my neighbour leaves?+
We find a new neighbour at no cost. If there is nobody within 30 days, your fee for that space is paused.
How long does an agreement run?+
At least 12 months, and never longer than your own lease.
