Jethro
Jethro (JethroData) is an enterprise software company that makes interactive business intelligence run fast on big data. Its index-based SQL engine sits between BI tools like Tableau, Qlik and MicroStrategy and data stored in Hadoop or Amazon S3, using full indexing, auto-cubes and result caching to return queries in seconds across tens of billions of rows and thousands of concurrent users - at Hadoop-scale cost and without manual data engineering.
Firebolt
Firebolt is a cloud data warehouse company building a low-latency, high-concurrency analytical database for engineers building data-intensive and AI applications. Founded in 2019 by former Sisense leaders, it decouples storage and compute to deliver sub-second SQL queries over terabyte- and petabyte-scale datasets, positioning itself on price-performance against Snowflake, Amazon Redshift, Google BigQuery and ClickHouse. Firebolt has raised roughly $269 million and reached a $1.4 billion valuation as a unicorn.
Rill Data
Rill Data builds the fastest business intelligence tool for humans and AI agents. Founded in 2020 by Metamarkets veteran Michael Driscoll, Rill takes a BI-as-code approach: dashboards, metrics, and business logic are defined in SQL and YAML, versioned in Git, and powered by embedded OLAP engines (DuckDB in Rill Developer, ClickHouse and Apache Druid in Rill Cloud). The result is sub-second, operational dashboards that teams actually use - processing more than 100 billion daily events for customers in programmatic advertising, media, and fintech.
ParadeDB
ParadeDB is an open-source PostgreSQL extension that brings Elasticsearch-quality full-text search and analytics directly into Postgres, removing the need to copy data into a separate search engine. Built in Rust on the Tantivy library, its pg_search extension delivers BM25-ranked search, faceting, and columnar analytics while preserving Postgres ACID guarantees and avoiding the brittle ETL pipelines that connect Postgres to Elasticsearch. Founded in 2023 by Philippe Noel and Ming Ying and backed by Y Combinator and Craft Ventures, ParadeDB raised a $12M Series A in 2025 and counts Alibaba, Modern Treasury, and Bilt Rewards among its users.
ClickHouse
ClickHouse is the open-source columnar database engineered for real-time analytics on petabyte-scale data. Born inside Yandex in 2009 and spun out as ClickHouse, Inc. in 2021, it now powers analytics for Anthropic, Tesla, Sony, Meta, Lyft, and roughly 3,000 other paying customers as a managed cloud service.
Kyligence
Kyligence is the company behind Apache Kylin, the open-source OLAP engine for big data. Founded in 2016 by the project's original creators, it now sells an AI-powered metrics platform and a copilot that lets non-technical employees chat with their business numbers instead of writing SQL.
