About us
Jane & Rosello is a founder-led design studio based in Spain that acts as a trusted design partner for technology, SaaS and developer-tool companies.
In the industry since
2011
Companies we've worked with
60+
Longest client partnership
7+ years
Mireia Jané and Josep Roselló started working as freelancers in 2011. Over time, their clients and projects grew, and their role changed: they went from delivering isolated pieces of work to becoming part of the teams they worked with. In 2014 they founded the studio to offer that same partnership to startups and technical teams that needed more sophisticated websites, better design and faster execution.
That studio is still just the two of us, and that's a deliberate choice. It means you work directly with the founders, with strategic thinking and no middlemen. We work as an extension of your team: available when you need us, fast to iterate and obsessive about detail.
We work with established tech companies, startups, cybersecurity companies and AI companies. Some of our clients:
- DigitalOcean, the NYSE-listed cloud platform for developers and SMBs.
- Traefik Labs, the company behind Traefik Proxy, one of the most widely used open source projects in the Docker and Kubernetes ecosystem. We've worked with them since 2019 and supported them through their biggest growth phase: from around 25,000 GitHub stars to more than 60,000, and from 1.2 billion downloads to more than 3 billion.
- Cyberbit, a leader in cyberattack simulation and security team training for enterprises, governments and managed security service providers.
- Lilt, the AI-powered enterprise translation platform backed by Sequoia Capital and Intel Capital.
- CrowdSec, the European collaborative security platform, hugely popular among sysadmins and the self-hosting community. Our redesign of their website and SaaS product was part of the momentum that led to their €14 million Series A.
- DataCamp, the AI and data learning platform with more than 20 million learners and thousands of business customers worldwide.
