It's 2025 & we act like it
We're a collective that embraces the new.
100% Remote
For us, modern slavery is stealing time away from people to live their best lives. Most work is bonded labour in a modern context taking advantage of people's circumstances.
People First
We build for people. For people like you. We also build along with people. For you. So we're people first – always.
Driven
We're driven by something. For some it's purpose, excellence, pushing the boundaries, doing simple things. Whatever it is, we stay driven.
Build together, from anywhere
We're constantly looking for the next talented team member to join one of our ventures. If you're interested in any of the above, email us at hello [at] fiftyseven [dot] is
Do good. Try things.
We believe businesses can do good, experiment with projects & do interesting things too

We do interesting things everyday. Some are original, some inspired. Some work, some give us important lessons. Some make money, some make progress.
What's important is that we do interesting things, everyday 😊
