+## License
+
+Cal.com, Inc. is a commercial open source company, which means some parts of this open source repository require a commercial license. The concept is called "Open Core" where the core technology (99%) is fully open source, licensed under [AGPLv3](https://opensource.org/license/agpl-v3) and the last 1% is covered under a commercial license (["/ee" Enterprise Edition](https://github.com/calcom/cal.com/tree/main/packages/features/ee)) which we believe is entirely relevant for larger organisations that require enterprise features. Enterprise features are built by the core engineering team of Cal.com, Inc. which is hired in full-time. Find their compensation on https://cal.com/open.
+
+> [!NOTE]  
+> Our philosophy is simple, all "Singleplayer APIs" are open-source under AGPLv3. All commercial "Multiplayer APIs" are under a commercial license.

+> [!TIP]
+> We work closely with the community and always invite feedback about what should be open and what is fine to be commercial. This list is not set and stone and we have moved things from commercial to open in the past. Please open a [discussion](https://github.com/calcom/cal.com/discussions) if you feel like something is wrong.
