SHARE Self-service data analytics startup Dremio Corp. said today it has closed on a $135 million late-stage round of funding that values it at more than $1 billion. Sapphire Ventures led the Series D round, which brings Dremio’s total funding raised to $250 million. Existing investors Insight Partners, Lightspeed Venture Partners, Norwest Venture Partners, Redpoint Ventures and Cisco Investments also participated in the round. Dremio’ software is based on the open-source Apache Arrow software framework for developing data analytics applications that process columnar data. It’s used by companies to connect with or replace cloud data warehouses and is compatible with a variety of popular business intelligence front ends. The software enables users to access information stored in data lakes directly without having to load extracts into intermediary data stores, a task that’s considered a major chore by data scientists.
