Firebolt
Firebolt is a cloud data warehouse company building a low-latency, high-concurrency analytical database for engineers building data-intensive and AI applications.

Firebolt has raised roughly $269 million and reached a $1.4 billion valuation as a unicorn.
Last9
Last9 is a unified observability company that helps engineering and DevOps teams monitor high-cardinality metrics, logs, and traces without the ballooning costs of legacy tools. Built around a Prometheus- and OpenTelemetry-compatible telemetry warehouse called Levitate and a pre-ingestion Control Plane that filters, reshapes, and routes data, Last9 has been used to observe some of the largest live-streaming events in the world - including peaks of roughly 59-61 million concurrent viewers. Founded in 2020 and backed by Sequoia/Peak XV's Surge, Better Capital and others, it targets cost-efficient, full-fidelity observability at enterprise scale.
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.
