Cockroach Labs builds CockroachDB, a distributed SQL database engineered to survive failures the way its namesake insect does. Founded in 2015 by three ex-Google engineers, the company combines the horizontal scalability of NoSQL with the strong consistency and PostgreSQL compatibility of a traditional relational database. CockroachDB powers mission-critical workloads at banks, retailers, gaming platforms, and AI companies that need to stay online through outages, scale across regions, and keep data inside specific jurisdictions for compliance.
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.
Eliot Horowitz is the founder and CEO of Viam, a New York robotics-and-automation software platform that lets developers build, deploy, and manage machines in the physical world. He wrote the original core code of MongoDB, which he co-founded in 2007 and steered as CTO for 13 years through a 2017 IPO and a market cap that climbed into the tens of billions. After tinkering with a cat feeder, a chess-playing robot, and a smarter sprinkler during the pandemic, he concluded that robotics hardware had outrun its software, and built Viam to close that gap.
Philippe Noël is the co-founder and CEO of ParadeDB, an open-source Postgres extension that brings Elasticsearch-grade full-text search and analytics directly into the database, eliminating the brittle ETL pipelines companies build to sync Postgres with a separate search engine.

In 2025 ParadeDB raised a $12M Series A led by Craft Ventures, with customers including Alibaba, Modern Treasury, and Bilt Rewards.
Spencer Kimball is the co-founder and CEO of Cockroach Labs, the company behind CockroachDB, a distributed SQL database built to survive almost anything you throw at it. Long before databases, he co-wrote GIMP as a Berkeley class project in 1995, spent roughly a decade as an engineer at Google working on its file-system guts, and built a photo startup that Square acquired. He named his database after the one creature famous for being nearly impossible to kill - which turned out to be the perfect pitch.
Will Manning is the co-founder and CEO of Spiral, a New York data company building infrastructure for the moment machines became the main consumers of data. He spent nearly a decade at Palantir co-creating and scaling Foundry, then set out to fix a bottleneck nobody else seemed bothered by: GPUs that can swallow terabits per second, fed through legacy file formats that make CPUs decompress everything first. His answer is Vortex, an open columnar format he donated to the Linux Foundation, and Spiral, the exabyte-scale system built on top of it. Spiral launched from stealth in September 2025 with $22M from Amplify Partners and General Catalyst.
