About Sifa ID

Professional identity you actually own

Sifa ID is a professional identity network built on the Atmosphere, the same open network behind Bluesky. Your career history, skills, and endorsements live in your own data server, not in ours. Switch providers, leave Sifa, or build your own client. Your data stays yours.

Why we built this

LinkedIn controls the professional identity of close to a billion people. If they lock your account, your career history disappears. If they change their API, every tool that depends on it breaks. Professional identity is too important to live inside one company's database.

How it works

Sifa reads and writes professional profile data to your data server. We provide the interface: the import tools, the profile pages, the endorsement system. The data is yours, stored where you choose, portable to any compatible app.

Hosted in Europe

Sifa's servers run on Hetzner infrastructure in Germany. Application, database, analytics: all EU-hosted and governed by EU law. Pair that with a European data server like Eurosky and all your data stays in Europe. Read our privacy policy.

The name

Sifa is Swahili for "praise, reputation, and qualification." It's part of Singi Labs (from msingi, "foundation"), alongside Barazo (from baraza, "community council"). The three names match what we're building: community-owned professional infrastructure, from the ground up.

The founder

Sifa is built by Guido X Jansen, a community and conversion specialist based in the Netherlands. Guido has spent two decades connecting technology and community, from the Joomla community in 2005 to the Magento ecosystem and developer relations at companies like Euroflorist and Spryker. Sifa grew out of a simple frustration: why does a platform own your professional reputation when the technology exists to own it yourself?

Open standards

Sifa's professional profile lexicons are open source under the MIT license. The id.sifa.* namespace is a shared standard any developer can build on.

Standing on the shoulders of

Sifa exists because of the open source community. Every layer of our stack, from the operating system to the icons in the interface, is built and maintained by people who share their work freely. We are grateful to them and would not be able to build Sifa without.
