Lightdash began as a scrappy internal tool that a customer asked to use. Hamzah Chaudhary turned that accidental signal into a broader argument: data teams should build with the discipline, freedom and leverage of software teams.
Lightdash is an open-source business intelligence platform built natively on dbt. It turns a data team's dbt models into a governed semantic layer, letting analysts define metrics as code and letting everyone else explore data - and, increasingly, ask AI agents questions - without writing SQL. Founded in 2020 (originally as Hubble in Y Combinator's S20 batch), it positions itself as an open, developer-first alternative to Looker and is backed by Accel, Shopify Ventures, Operator Partners and Y Combinator.
