> Atlan is hosting Context Conference, bringing together the leaders and builders at the frontier of giving AI the context it needs to understand their business. It runs online on October 28, 2026, from 11:00 AM to 2:00 PM ET. Atlan co-founder Prukalpa Sankar opens and closes the day. Leaders from AstraZeneca, BNY and Verizon share why they invest in context and what they get from it. Registrants get early access to The AI Context Gap, a new study from MIT Technology Review Insights. Register: https://atlan.com/context-conference/

**Built on open source. Open by default.** Like you, we hate being locked into closed, black-box platforms. That's why Atlan's core platform is built on leading open-source projects and every action is API-driven. API docs: https://apidocs.atlan.com/

 - Phil Warner, Director of Data, Boulevard (stack: Salesforce, Snowflake, AWS S3, dbt)

## What customers build on Atlan's open APIs

**A $6B fintech generates programmatic documentation.** Atlan's OpenAPIs push an automated README template to new Redshift assets in Atlan. The template standardizes documentation for developers with pre-defined sections and encourages asset owners to create documentation on time. **10K+ API calls per week.**

**Delhivery increased documentation by 250%.** Atlan auto-populated column descriptions for 90% of Delhivery's assets and assigned owners by scanning query log history. Automation helped developers document assets at scale and reduced time-to-ownership. **90% of column descriptions automatically deduced by Atlan.** Stack: AWS Glue, Airflow, Jira.

**Groupe La Centrale created a custom wrapper for DynamoDB.** The team created a public script on GitHub to programmatically ingest metadata from DynamoDB: the bot reads table metadata from a DynamoDB template and publishes it to Atlan via OpenAPIs. Stack: AWS Redshift, AWS Glue, Tableau. [GitHub repo](https://github.com/groupelacentrale/atlan-public-integration)

"We liked that Atlan has a fundamentally open philosophy... This gave us the ability to customise the product for our end users - bringing together the best of open-source with a polished, off-the-shelf user experience."
 - Akash Deep Verma, Director, Data Engineering, Delhivery
