Algae

Algae set out to let anyone own a piece of a building: fractional, tokenised real estate from €10. It was pitched in Madeira in June 2021 and grew a community in Lisbon through meetups of fifty people and more.

Its flagship project was a 450 m² former commercial space in central Lisbon, to be turned into a coworking space with a podcast studio. About €280,000 of the €770,000 needed was raised. Then the payment provider went bankrupt, and the project stopped.

In January 2025 the real-estate concept was closed: too early for its market. The lessons were written down in public, and they shape how everything since is built — sell before raising, test before building, and never carry four complex things at once.
