Empowering sex workers through intelligent tech.modern thinking.thoughtful design.

Our mission is to build products and services to empower sex workers.

We are a collective of sex workers and technologists.

Assembly Four was founded on the belief that impact is more important than profit. We strongly believe that having the ability to make decisions about our bodies and sexual lives is a fundamental human right. Anyone should be able to make these choices without fear, violence or discrimination. Sex workers are still fighting for this right.

In collaboration with sex workers across the globe, we create products and services that help them thrive, not just survive. We are a small team with a specialised understanding of the complex challenges workers face and are dedicated to providing solutions to amplify their voices.


All in one advertising for Escorts

Stepping away from clunky design and carelessness of traditional ad platforms, Tryst is a refreshing change in both presentation and mission. Designed not only to provide workers with an easy way to manage clients, but also with privacy, safety and security at the top of our priority list. Tryst, like Switter, has been built while avoiding the use of US companies, prioritising the privacy of the workers who reside on our platforms.

Although early days, we are proud to say that we have already implemented features that radically change the way escorts advertise, including wider options around gender and race, dedicated disclosure options for transgender workers, and in-platform messaging.

A sex work-friendly social platform.

Early 2018 saw the passing of US law FOSTA/SESTA which resulted in the mass culling of millions of sex workers worldwide from the internet. This resulted in thousands of people in heightened risk of physical harassment, violence, and even death. We started Switter as the first step to giving Sex Workers their autonomy back.

Switter has amassed over 200,000 users with over 5.5 million status posted in a mere 10 months. The space is open to anyone involved in the sex industry; providers, clients, and allies. It is an open and free community where sex workers have the ability to connect, advertise and screen.

Switter is built on Mastodon, the world's largest free, open-source decentralised microblogging network.

Switter is live!
