At zeitkapsl, we believe your photos should belong only to you. That’s why we’re building a privacy-first photo storage service — something that feels as effortless as Google Photos, but without the trade-off of giving your life away. We’ve spent the past few years designing and building the technical foundation.

The product is live, and people who care about privacy already use it. Now we’re looking for a co-founder who can help us bring this mission to more people — through thoughtful growth, authentic storytelling, and the right partnerships. All position can be internships, bachelor/master thesis, part time contracts or freelancing opportunities.
