Co-Star is a mobile app that delivers highly personalized daily horoscopes by building a full natal chart from a user’s exact birth data and combining NASA planetary positions with insights from human astrologers, processed through a proprietary AI engine. It updates daily with readings, offers personality analysis, and lets users connect with friends to compare compatibility, making astrology a social experience. In 2023 it launched The Void, an in-app feature that provides AI-generated answers to user questions based on their chart. The app uses a freemium model, offering premium chart readings and extended Q&A options, aimed at reducing loneliness by fostering daily reflection and connection through digital wellness and social networking around astrology.

↓ -2%Midjourney acquired the astrology app Co-Star. Midjourney, an AI lab best known for its LLM-powered image and video generators, has acquired the social astrology app Co-Star, according to Bloomberg. The deal terms were not disclosed. Co-Star, which reportedly has about 4.3 million monthly active users, is mostly used to help people determine their astrological birth charts, which they can then share with other friends on the app. Co-Star uses both AI and humans to write horoscopes, compatibility assessments, and other advice based on a user's astrological information. Midjourney seems to be casting a wide net when it comes its product lineup. The company seems almost synonymous with the Discord server where users can generate text and images - there is no stand-alone Midjourney app - yet the AI lab is also trying to build a medical arm and spa. Why not throw an astrology app in the mix? Co-Star's team of two dozen employees has joined Midjourney as part of the acquisition. Given the team's experience in building consumer apps, Midjourney could perhaps finally get its own stand-alone app. October 13 - 15 San Francisco Scale faster. Grow your portfolio.

Midjourney has acquired astrology app Co-Star and is developing its first standalone image-generation application. The artificial intelligence startup's moves represent its latest push into new business areas following an announcement last month about ambitious expansion plans. The acquisition of the popular astrology app marks a significant diversification for Midjourney, which has primarily focused on AI-powered image generation. Details about the acquisition terms were not disclosed. The company is simultaneously working on its own image-generation app, expanding beyond its current offerings. These strategic developments signal Midjourney's broader ambitions to establish presence across multiple consumer-facing product categories.
