Midjourney Acquires Co-Star, the Astrology App With 4.3M Monthly Users

Midjourney has acquired Co-Star, a social astrology app reporting 4.3 million monthly active users. According to Bloomberg, reported by TechCrunch AI, Midjourney completed the acquisition with undisclosed terms. The deal brings Co-Star’s 24-person team into Midjourney and marks a significant expansion of the AI lab beyond its Discord-based image and video generation platform.

Co-Star’s User Base and Capabilities

Co-Star operates as a social platform where users generate and share astrological birth charts with friends. The app combines generative AI and human expertise to produce horoscopes, relationship compatibility assessments, and personalized astrological guidance tailored to each user’s chart data. According to TechCrunch AI, Co-Star reportedly maintains approximately 4.3 million monthly active users, positioning it as a meaningful asset in the consumer-facing AI market.

The acquisition folds Co-Star’s 24-person team directly into Midjourney, potentially strengthening the company’s consumer product capabilities. Midjourney’s core offering—text-to-image and text-to-video generation—operates exclusively through Discord servers without a native standalone application. Co-Star’s engineering and product experience building consumer-grade mobile experiences could address this constraint.

Midjourney’s Portfolio Expansion Strategy

This acquisition is not Midjourney’s first move beyond image generation. According to TechCrunch AI, the AI lab is reportedly developing medical and spa product lines alongside its generative media platform. The Co-Star purchase extends this pattern of diversification into vertical-specific AI applications, though the strategic rationale connecting astrology, wellness, and medical services to Midjourney’s core competency remains unclear.

The undisclosed deal terms prevent assessment of how Midjourney valued the astrology app relative to its user base and revenue profile, making it difficult to gauge the financial commitment behind this expansion effort.

Why This Matters

This acquisition matters to three audiences making distinct decisions. For Midjourney stakeholders, the deal tests whether the AI lab can execute in consumer-facing verticals beyond image generation—a critical question for investors assessing the company’s ambitions and ability to diversify revenue. For Co-Star’s user base, product continuity and feature roadmap under Midjourney ownership are the immediate concern; astrology apps live or die on user trust and consistent content quality. For founders building standalone AI-powered consumer apps, this signals that Midjourney sees acquisition of established user communities as faster than building from zero, potentially increasing acquisition multiples for apps with demonstrated monthly active user bases in the millions.
