Innovation to change the world.

I'm Evan Henshaw-Plath, an activist and technologist passionate about building commons-based social media apps that prioritize equity and sustainability. With experience in developing platforms like Twitter, I've explored innovative digital spaces through projects like Planetary on Scuttlebutt and nos.social on Nostr.

Here, you'll find insights into my work and thoughts on creating digital public spaces that foster genuine community engagement, innovation, and sustainability. Join me in redefining the digital landscape and cultivating the utopian energy of new communities.




About Me

I'm a proven innovator who can take projects from a need through discovery, validation, design, development, and release.

From startups and open source social justice projects through work with the biggest companies, my experience shows me how to build digital products that work and meet the needs of users.

Innovation work is messy and it takes somebody who is comfortable with that while creating a path forward for a team.

I'm looking for meaningful projects which have an impact on the world. Let's build tools that matter, that make people's live better, that are transformative in empowering people to change their communities and the world.


The idea of what to create is the easy part. What I do is figure out what should be created and then make it happen. I take a project from the initial evaluation of the space through users and running code.

"I knew Evan back at the beginning of his career. As a leader in a venture development company working closely with start-ups it was clear even then that I should do my best to keep hold of his coat tails. He clearly had even then unusually sharp insights into the interplay between humans and computers."
Revista Orsai
"A un grandulón un poco friki que recorre los jardines de su universidad, con mil proyectos en la cabeza y todo el futuro por delante."
