About Mother Duck
Don’t let the quirky name fool you:
At Mother Duck, we’re on a mission to make data warehousing fun, frictionless, and ducking awesome for developers and data practitioners building blazing fast internal and customer-facing analytics experiences. "We're building a cloud-hosted version of DuckDB, working hand-in-hand with the creators of the fastest-growing and fastest-improving query engine on the planet. Unlike other databases, Mother Duck was architected to unify local development with cloud operations to bridge the gap between software and data engineering workflows.

Our team is a mix of thoughtful, passionate, and empathetic data industry veterans. We’re shaking up assumptions on how data should be done! We empower and delight data practitioners using a novel cloud architecture. We believe in the power of single node databases, built on top of DuckDB, an open source foundation with a vibrant community. Our engineering team comes from a wide mix of backgrounds, running the gamut from data experts to generalists, from big tech to start ups, and SaaS companies to government and finance.

But no matter where we’ve come from, we’re passionate, collaborative and customer-focused. We work together as a team from across our engineering hubs in Seattle, San Francisco, New York, and Amsterdam.
