July and August were again quite active months, with 13 notable fundraising events. The list includes the 1.6 billion raise by Databricks and large rounds for Dataiku ($400M), Datarobot ($300M) and Grafana Labs ($220M).

It's interesting to see that the 2 major open source data visualization companies raised funds during the period: Preset (creators of Apache Superset, $39.5M) and Metabase ($30M).

It's also worth mentioning the launch of Voltron Data by Wes McKinney and Josh Patterson to further develop the Apache Arrow ecosystem and the $200M Couchbase IPO.
