Row Zero (now part of Databricks) is by far the best spreadsheet on the market - it's not even close.

Row Zero's fully Excel compatible, including keyboard shortcuts, long-tail pivot table configurability, 500+ built-in formulas like LAMBDA and LET, and real-time collab. But it scales 1000x beyond Excel (2 billion row limit vs 1 million for Excel), has built in connectors to everything (Databricks, Postgres, S3, Snowflake, etc), native Python support, deep AI integration with Databricks Genie, and all the security and data governance features to make big banks and healthcare providers comfortable. It's built by the team who brought Rust into AWS and rewrote S3's file system circa 2018.

We're used by individuals and small businesses all the way up to huge deployments in the Fortune 100.
