Curio.io Raises £2.5M to Turn Quality Journalism Into Audio for the Attention Economy

Curio.io, a London-based media technology company, has raised £2.5 million from Khosla Ventures and business angels to develop and grow its subscription audio platform for quality journalism. The company curates articles from a hand-selected portfolio of respected publications — including The Guardian, The Economist, Wired, and others — and converts them into high-quality audio and video productions, delivered through an app that subscribers can use during commutes, exercise, cooking, or any other context in which reading is not practical.

The proposition addresses a structural tension in modern media consumption. The publications that produce the most carefully researched and argued long-form journalism are also the most demanding to consume: they reward sustained attention, careful reading, and the kind of mental engagement that is difficult to sustain during the fragmented, multitasking reality of most people's days. Podcasts and audio-first media have demonstrated that people are willing to devote significant time to audio content during exactly these interstitial moments — but most podcast content is purpose-built for audio, and the existing body of quality written journalism is not. Curio.io sits at the intersection of these two realities: taking the output of the world's best long-form journalism and making it accessible in the format and context in which people actually have time to consume it.

The curation layer is central to the product's value. Rather than aggregating all available audio or simply text-to-speech converting anything on the internet, Curio's team selects articles based on editorial quality, enduring relevance, and the depth of the journalism they represent. The production quality of the audio — using professional narrators rather than synthetic voices — distinguishes the experience from automated read-aloud tools and positions it as a premium product for people who value quality journalism and are prepared to pay for a better way to consume it.

Khosla Ventures, the Silicon Valley-based firm known for backing ambitious technology companies, is a notable transatlantic investor for a UK media startup. The funding will be used to expand the content catalogue, develop the recommendation and personalisation features that help subscribers navigate a growing library, and grow the subscriber base.
