Which Platform Delivers ROI Faster: Alation or Atlan?

Atlan becomes an intelligence layer on day one, accelerating time to insight, automating policy enforcement, and lowering operating cost.

Business Outcome
Time to Discovery	Google-like NLP delivers instant, contextual results	Requires stewardship effort and curation
User Adoption	90%+ adoption across all personas in 90 days	Steward- and analyst-first; business adoption slower and requires training
Deployment Speed	Automated ingestion, immediate value	Months of professional services for configuration, and manual approaches
Lineage Precision	Automated column-level lineage with real-time updates	Table-level, deeper lineage requires manual set up
Business Engagement	Intuitive interface for every role	Steward-first workflows; adoption beyond technical users limited
Metadata Context	Embedded in Slack, Chrome, BI tools	Metadata siloed in tool, required constant context switching
Governance Scale	Automated policy enforcement with AI enrichment	Manual stewardship bottlenecks
Platform Flexibility	Open API-first enables unlimited customization	Closed architecture limits growth
Total Investment	60-70% lower TCO through automation	Tool + 3X services + 6X people costs
Cloud Readiness	Built cloud-first, AI-native from the ground up	Legacy with cloud limitations

Voices from the Front Lines

Real teams, real results

"Atlan just seemed to have more potential with extensibility, and the APIs. We wanted to build more than a data catalog and replace Amundsen, or even Alation. We wanted to build a metadata hub. The vision of Atlan totally makes sense. We're a fan!" — Mark Kidwell, Chief Data Architect, Autodesk
Autodesk chose Atlan over Alation for its superior extensibility and vision beyond traditional cataloging, enabling them to build a comprehensive metadata hub rather than just another catalog.
"We were up & running within a few weeks. The engineering effort was very low. That was a surprise because we spent a month setting up one connector with our previous data catalog. With Atlan, we had all our major sources onboarded within a few weeks." — Natalie Hallak, Director of Global Data Management, HelloFresh
HelloFresh experienced 10X faster deployment with Atlan compared to their previous catalog, with minimal engineering effort required.
"It's not just the technology, but the organization behind it. We really wanted a partner who would come in and help us really understand the power and benefit of this tool. We found that." — Michael Weiss, Product Manager, NASDAQ
NASDAQ chose Atlan for its partnership approach and comprehensive support, distinguishing it from vendor-focused alternatives.
"Our priority was to find a tool that business wants to use, not have Informatica like scenario. Alation wasn't like the easiest to use, it was super expensive, their user profile was confusing. Atlan's simple UI makes it easy for someone senior like me to traverse. Atlan was bang on the buck - what you got us for the package was amazing." — Data Leadership, Elastic
Elastic emphasized Atlan's superior user experience and value proposition over Alation's complex and expensive approach.
"Transparency was a key deciding factor. When we were deciding, Atlan was clearly transparent of what you could do and you couldn't do. And Alation gave us a lot of promises that we believed, but they didn't follow through." — Data Leadership, Algolia
Algolia switched from Alation to Atlan within 6 months due to Alation's inability to deliver on promises and lack of transparency.
