Curio (curio.io), operated by Curio Labs, was a London-based audio-journalism subscription app founded in 2016 by Govind Balakrishnan and Srikant Chakravarti. It turned articles from premium publishers into professionally narrated audio and later added AI-generated personalized episodes. Backed by 500 Global (formerly 500 Startups), EarlyBird, Draper Esprit, Cherry Ventures and Horizons Ventures, it raised over $15M before the founders wound the company down after eight years, citing AI and big-tech competition; they have since moved on to a new venture (Gibran). Enrichment probe finds no public API, developer portal, documentation, SDKs, or OpenAPI surface — curio.io now serves a closure/landing page only.
