Philosophy
Open data, commercial product. The raw medical ontology — conditions, symptoms, relationships — is open source. Anyone can inspect, contribute, and build on it. The commercial API, SDKs, differential engine, and enterprise features are the product. This is the same model used by Elastic, HashiCorp, and GitLab. Open source earns trust. The product earns revenue.Why Open Source Matters
- Trust: Developers and clinicians can inspect the data
- Quality: Community contributors catch errors and add coverage
- Credibility: An open knowledge base is more trustworthy than a black box
- Ecosystem: Others building on your standard strengthens your position
