Our Story
Sustainsys was founded by Anders Abel in 2017 with a clear vision: to build a sustainable business model for open source, and a workplace he would actually want to work at himself. The Sustainsys.Saml2 library, rooted in consulting work from 2012 and now with over 30 million downloads, became the natural foundation.
Today the library is actively maintained thanks to our customers’ support agreements, without anyone sacrificing evenings and weekends.
When the creators of IdentityServer founded Duende Software, we became their partner for support, consulting and training.
How We Work
- A Partner, Not a Permanent Fixture. When the project is done, we hand it over to your team, and we’re always there when you need us again.
- Sustainable Open Source. Customer support agreements keep Sustainsys.Saml2 maintained over time.
- Sustainable Work-life Balance. Fully committed at work, fully present outside of it.
