About
Atlan is a data catalog and workspace company founded in 2019 in Singapore that has raised over $200M at a $1.7B valuation to build the collaboration layer for data teams. The platform provides a unified workspace where data engineers, analysts, and data scientists can discover data assets, view lineage, add documentation, set ownership, and enforce governance policies across their entire data stack. Atlan integrates with over 50 data tools including Snowflake, dbt, Tableau, Airflow, and Looker, automatically pulling metadata to keep the catalog accurate without manual curation. The company differentiates from legacy data catalog tools through its Slack-like collaboration features, embedded AI for automated documentation generation, and developer-friendly APIs that enable programmatic governance. Atlan serves data-driven organizations from growth-stage tech companies to Fortune 500 enterprises that have invested heavily in the modern data stack and need a governance layer to extract full value from those investments. The company has built strong market positioning in the data catalog segment and competes with Alation and Collibra in the enterprise governance market.

About
Prometheus is an open-source systems monitoring and alerting toolkit — originally developed at SoundCloud in 2012 and donated to the Cloud Native Computing Foundation (CNCF) in 2016, where it became the second CNCF project to graduate (after Kubernetes). Prometheus collects time-series metrics from applications and infrastructure through a pull-based model (scraping HTTP endpoints), stores them in a local time-series database, and provides PromQL (Prometheus Query Language) for flexible metric analysis and alert definition. The Prometheus ecosystem is maintained by the open-source community with major contributions from Grafana Labs, Red Hat, and cloud providers.
