Sifa ID: A professional profile you don't have to fake

Professional identity on the AT Protocol. Powered by your network and real activity, not just your words.

Sifa ID is a professional identity layer built on the AT Protocol, the open network behind Bluesky. Instead of a static page you fill out yourself, your profile fills in from your real activity across apps and communities. Sifa ID is available today for anyone with a Bluesky account. 192 people have already claimed their profile. No Bluesky account yet? It takes two minutes, and that account works across every AT Protocol app.

Your online profile should not be this broken

The feed you are watching is full of engagement bait, humblebrags, and AI-generated content.

You scroll past ghost job listings that were never real. You want to share your actual work with the people who matter: potential clients, employers, collaborators. But the algorithm buries it unless you become a player in this performative post-generating puppet show. You know it is hollow. Everyone knows it is hollow.

Meanwhile, profiles are lists of job titles everyone typed in themselves, a summary you wrote yourself, and likes from people who never even read your work. You are good at what you do, but the platform gives you no way to really show it without the theatrics. It only measures what you do on the platform. Sharing external links is punished.

And then when you post something, it asks you to pay to reach your own followers. The connections you built. Your colleagues, your partners, your community. "Boost your post to make sure the people that matter to you see it." That is not a feature. That is betrayal.

What if your profile showed the whole picture?

What if your profile was already being built, just by showing up and doing your work?

On the AT Protocol, your data lives in a personal data server that you control, not locked inside any single app. Sifa reads from it. Your Bluesky posts are already there, along with your forum contributions, code commits, photos, and event attendance. As more apps join the protocol, your profile fills in on its own.

Be part of the communities you care about and curate what shows up if you want. Sifa takes care of the rest. No re-hashing your life for yet another platform.

Your network makes your profile credible

On LinkedIn, it is just you polishing a page. Sifa works differently. Your profile becomes more complete and more credible because of the people around you and how they respond to what you do.

Colleagues confirm where you work. Identity verification services prove your links are real. People you have met in person vouch for you. These trust signals come from real relationships, not a button click.

And then there is the activity itself. You help someone in a forum. You write a guide that people actually use. You answer questions. The community reacts, and that shows up on your profile: not a summary you wrote about yourself, but actual contributions confirmed by the people who were there.

"I managed communities for 25 years. I know what real contribution looks like, and it has never shown up on a professional profile."
Guido X Jansen, founder

Why now

43+ million people already have an AT Protocol identity, and the developer tooling caught up in early 2026. Nobody has defined how professional networking works on this protocol yet. I published the first open standard for it.

Full profile with career history, education, skills, projects, credentials, publications, volunteering, awards, and languages. LinkedIn data import (runs in your browser, nothing leaves your device).

Where this goes

As the AT Protocol grows, so does your profile. Every new app that joins the network is another source of real activity that shows up on your Sifa page without you doing anything extra. Your professional identity becomes something you build once and take everywhere, not something you rebuild on every new platform.

And it works the other way too. Picture an organization looking for your expertise. Today, they search profiles where people typed a keyword in a skills field. With Sifa, they could find you because you have been answering real questions in real communities for the past two years. Your real work across platforms is aggregated, validated, and becomes findable. That is reputation capital, and it is yours.

Part of Singi Labs

Sifa is one of two products from Singi Labs, built by Guido X Jansen in the Netherlands. Its sibling Barazo is a distributed forum on the AT Protocol. The two feed each other: what you do in Barazo communities shows up on your Sifa profile. Do good work where it matters, and your profile reflects it.
