Midjourney buys Co-Star to widen consumer AI beyond art

Midjourney acquired Co-Star, adding a social astrology app to an AI business built around image and video tools. The price was not reported.

The acquisition gives Midjourney a consumer brand with a reported 4.3 million monthly active users and a product built for daily, personalized interaction. It also brings in a team experienced in mobile social software, an area where Midjourney has had a thinner public footprint.

Co-Star brings 4.3 million users

Co-Star lets users generate astrological birth charts and share them with friends inside the app, according to the report. Its service combines artificial intelligence with human-written material to produce horoscopes, compatibility readings and other guidance tied to a user’s astrological profile.

That model is different from Midjourney’s core identity. The AI lab is best known for creative generation tools that users access through a Discord-based workflow rather than a dedicated consumer app, according to the source article.

Roughly 24 Co-Star employees moved to Midjourney as part of the transaction, the report said. For Midjourney, the personnel may be as important as the app itself because Co-Star’s staff has already built a product that keeps consumers returning for personalized updates.

Discord roots meet mobile habits

Midjourney’s business has been closely associated with text-to-image and video generation, powered by large language model and generative AI systems. The Co-Star purchase suggests the company is testing how far its technology and brand can travel beyond creative production.

The source article said Midjourney has also explored a medical arm and a spa, pointing to a broad approach to product development. Co-Star now adds a consumer lifestyle property to that list, placing the company in a category built on identity, community and daily engagement.

The strategic logic is not only astrology. A social app gives Midjourney a new distribution channel, a different user base and a live test of AI-assisted personalization outside image generation.

Consumer AI gains another test

The deal lands as AI companies search for products that can become habits, not just tools used when a user has a specific task. Co-Star already operates around recurring prompts: daily readings, compatibility checks and profile-based updates.

For the wider consumer AI sector, the purchase shows how labs may buy established communities instead of building every interface from scratch. The mechanism is straightforward: existing users reduce launch friction, while product teams bring lessons about retention, notifications and social sharing.

The main risk is brand fit. Midjourney’s core audience knows it as a creative AI system, while Co-Star’s users come for astrology and social discovery. If the two identities are forced together too quickly, Midjourney risks confusing both groups.

Midjourney weighs Co-Star integration

If Midjourney keeps Co-Star largely separate, the acquisition can function as a consumer app laboratory. At the global level, that would add one more example of AI capital moving from model development into everyday digital services; for Midjourney, it would preserve Co-Star’s user habits; for the sector, it would favor acquisition-led distribution strategies.

If Midjourney uses Co-Star’s team to build a broader mobile app, the effect would be different. Global AI competition would shift further toward consumer interfaces; Midjourney would gain a path beyond Discord; image and video rivals would face more pressure to own the full user relationship.

If the integration fails to hold Co-Star’s community, the purchase becomes a warning about category drift. The macro effect would be narrower appetite for lifestyle AI deals; Midjourney would absorb talent but lose consumer momentum; the industry would treat social personalization as harder to transplant than technical capability.

The open questions are concrete: whether Co-Star keeps its brand, whether Midjourney launches a standalone app, and how much of Co-Star’s horoscope engine changes under new ownership. The answers will show whether this is a small lifestyle acquisition or the start of a wider consumer AI push.
