Midjourney, the AI image-generation company, has acquired Co-Star, a popular personalized astrology app. Bloomberg first reported the deal on July 24, 2026, and Midjourney confirmed it the same day with an announcement on its own site (The Verge).

The deal reportedly closed in spring 2026, months before the public announcement. Financial terms were not disclosed (The Verge).

Co-Star is a free app that delivers daily horoscopes and lets users check astrological compatibility with friends. It combines human editorial judgment, data from NASA, and AI to produce personalized daily advice (The Verge). Its approach to blending curated content with data-driven personalization has earned it a substantial consumer following since its launch.

Co-Star founder Banu Guler will remain in charge of the app after the acquisition, Midjourney founder David Holz said. Guler will also take on the role of Midjourney's chief design officer, according to Bloomberg. She and her team will help Midjourney build the company's first native apps, including one dedicated to image generation (The Verge).

That last detail carries the most strategic weight. Midjourney currently delivers its AI image models through the web and through Discord, the chat platform that served as its primary interface during its early growth. The company has no native mobile apps of its own. Bringing in Guler's team, which shipped and iterated a polished consumer mobile product at Co-Star, gives Midjourney an experienced app-design operation that it did not previously have in-house.

Midjourney characterized the acquisition as centered "around Product and Design" (Midjourney). That framing lines up with Guler's dual mandate: running Co-Star as a going concern while simultaneously taking on the chief design officer role across Midjourney's broader efforts.

The structural context matters here. Midjourney is a 60-person research lab, distributed, self-funded, and community-funded. It is also working on hardware and medical projects, according to the company's own site. Those are unusual adjacencies for an image-generation company, and they suggest Midjourney is building toward something broader than a Discord-based text-to-image tool. The Co-Star acquisition fits that pattern: acquiring a consumer-facing mobile product team rather than licensing technology or hiring individual designers.

What stands out is the mismatch between the two products on the surface. Midjourney builds generative image models. Co-Star builds astrology content. The connective tissue is not the subject matter but the interface challenge. Both companies have to translate complex underlying systems into experiences that casual users can engage with daily. For Midjourney, that has meant Discord bots and a web console. For Co-Star, it has meant a mobile app that turns planetary position data into snackable, shareable content. Guler's expertise is in the latter, and that is what Midjourney needs if it intends to move beyond its current distribution channels.

The decision to keep Co-Star operating independently, with its founder still at the helm, also tells something about how Midjourney is approaching the deal. This is not an acqui-hire, a common tech-industry pattern where a company is bought primarily for its talent and the product itself is shut down. Co-Star continues. Guler adds responsibilities. Whether that dual-role structure works in practice is an open question, but it signals that Midjourney values Co-Star as both a team and an active product.

The broader context here is about engagement. Midjourney's move into native app development arrives as the generative AI tooling landscape shifts from novelty toward retention. Early adoption of image generators was driven by curiosity and experimentation. Sustained engagement requires something closer to a daily habit, and native mobile apps are the standard delivery mechanism for that. Co-Star's core product loop, a daily check-in that gives users something brief and personal, is a well-proven retention pattern. Importing the team that built it into an image-generation company suggests Midjourney is thinking beyond model quality and toward product experience as the next competitive axis.

For a company that has grown without venture funding and now spans image generation, hardware, and medical projects, adding a consumer mobile design lead is a concrete step toward broadening its reach. The Co-Star acquisition is small in scope, a single deal with undisclosed terms. But it brings Midjourney something it could not build from within on a short timeline: a team that has shipped and scaled a consumer mobile app.
