Amavi Capital
Amavi Capital is a Belgian built-world investment firm that backs property and real-assets technology across Europe. Amavi's water footprint comes through building-efficiency tech: it has backed two water companies, greywater recycler Hydraloop and leak-detection startup Shayp. As of 2026 Amavi runs both a PropTech and real-estate-platform strategy from Ghent and Stockholm.

The take
Amavi Capital is the kind of fund that confuses a water search. It is not a water fund. Frédéric Van den Weghe and Arne Allewaert built Amavi in Ghent in 2020 around one idea: the built world, the buildings and sites we all live and work in, is where technology still has the furthest to travel. Water shows up on that map as a way to make buildings use less of it, never as a thesis of its own.
Amavi's two tracked water companies are, at heart, pieces of building plumbing reimagined. Amavi seeded Shayp, a Belgian startup whose leak-detection software watches a large building's water in real time (the City of Brussels credits it with saving more than 50 million litres a year), and Amavi backed Hydraloop, the Dutch greywater recycler that treats shower and bath water so a home can use it twice. Three water deals across two companies, sitting inside a much larger proptech portfolio.
Amavi has grown well past those early water cheques. It bought Sweden's SF Ventures in 2023 to open a Nordic office, and its newest money goes into Real Estate Operating Platforms, consolidating fragmented real-asset businesses like European carwashes, Iberian campsites and Nordic marinas. Amavi is the cleanest case I track of a fund water founders keep mistaking for one of their own: a proptech and real-assets investor first, where water rides along whenever a technology happens to save a building water.
