Onehouse, a managed data lakehouse service, raised $8 million in seed funding co-led by Greylock and Addition.

Onehouse provides a cloud-native managed lakehouse service that makes data lakes easier, faster and cheaper. Onehouse blends the ease of use of a warehouse with the scale of a data lake into a fully managed product. Engineers can build data lakes in minutes, process data in seconds and own data in open source formats, not locked away to individual vendors.
