01In practice
Built to power modern circular communities.
A drill borrowed next door, a stroller passed on, a basket of harvest shared. TackBird makes exchange as simple as sending a text — and brings the whole community alive.

06Why now
The time is ripe.
Four shifts converge — each one pushing neighbor-to-neighbor help forward.
Community void
Nextdoor never took root in Finland and Facebook neighborhood groups are fading. There is room for a Finnish alternative.
Circular economy
The EU is steering toward a circular economy and Sitra is talking about durable consumption. Borrowing and sharing have gone mainstream.
Buildings go digital
The 2022 Housing Companies Act enabled remote AGMs. Digital channels are no longer optional.
Hunger for connection
The pandemic left a community deficit in Finland. People are looking for their nearest neighbors again.
