We’re the team behind WebContainers, the groundbreaking technology that made it possible to run Node.js right in your browser. No installs, no setup, just instant dev environments. That innovation kickstarted our journey in 2019 and powers the blazing-fast online IDE used by over a million developers every month. We took everything we learned from building WebContainers and used it to create Bolt.new, the fastest way to go from idea to production without writing traditional code. Think of it as the Canva or Figma for full-stack applications: a next-gen, AI-powered builder that lets you create, edit, and deploy web and mobile apps instantly, right in your browser.

We build an open source data platform on Kubernetes. The product (Stackable Data Platform - SDP) bundles 12+ open source data tools (Trino, Apache Kafka, Apache Airflow, Apache Superset, etc.) and makes them work together. Right now everything is Infrastructure-as-Code only. We need someone to build a UI layer on top.
