About Us


Our Mission

We fill the empty offices, reduce the carbon footprint of the commercial real estate industry, and help businesses run more profitably and sustainably.

For the benefit of companies

Through our Fiveoffices online marketplace, companies can efficiently scale according to their specific needs, significantly lower their operating costs, and improve their carbon footprint.

Our Platform

We connect landlords, tenants and subtenants for their excess office space. Pairing guests looking for space with hosts offering to rent currently available offices, our platform offers a full search, match and workflow facility to adjust office occupancy with the changing requirements for space size, rent duration, flexibility and new onsite working patterns.

For the benefit of us all

By sharing what is already built, lit, cooled and heated, we together can create much more sustainable business models.
