Midjourney just made its first-ever acquisition. The bootstrapped AI image company — profitable since month six, $500M in annual revenue, and still beholden to no outside investors — bought Co-Star, the viral social astrology app with 4.3 million monthly users. The deal closed in spring 2026 and went public on July 24. Co-Star founder Banu Guler joins Midjourney as Chief Design Officer while retaining full control of the app. On the surface, this is an odd pairing. Underneath, it reveals what Midjourney actually needs right now — and it has nothing to do with horoscopes.
The Real Play: Distribution, Not Astrology
Discord built Midjourney. It also boxed the company in. Today, every major platform bundles AI image generation: Adobe Firefly ships inside Creative Cloud, GPT Image 1.5 lives inside ChatGPT, and Stable Diffusion is free and open-source. Being the best AI image tool is no longer enough as a business moat. You need distribution you own.
Co-Star gives Midjourney exactly that. Four-point-three million monthly actives, a polished mobile app, and — critically — a 24-person team with real experience building, shipping, and monetizing consumer software. Midjourney has roughly 40 employees generating $500M in revenue. That is an insanely lean operation, but it also means the company has almost no consumer product muscle. Co-Star’s team is the missing piece.

Bloomberg’s framing is accurate: “buying an established brand rather than growing one signals the same impatience showing up across the sector, where the fastest route to users and product talent is increasingly to acquire both at once.” OpenAI has done this. Meta’s $2 billion Manus acquisition was read the same way. Midjourney, the company that built itself without touching venture capital, is now playing the same acquisition game — just four years later and with its own cash.
Co-Star Is the Opening Move in a Larger Bet
This is not Midjourney’s first non-image venture. In June 2026, the company launched Midjourney Medical with over $74 million invested in a full-body ultrasonic scanner — a 60-second whole-body scan using sound waves and water, with no radiation. They are also building a Midjourney Spa in San Francisco: a 25,000-square-foot space with the scanners alongside hot tubs, saunas, cold plunges, and a gym, planned for 2027.
The thread connecting image generation, astrology, and whole-body ultrasound scanners is David Holz’s stated philosophy: computers should be tools that reveal our humanity to ourselves. Co-Star’s Banu Guler shares that framing explicitly. “At a time when it feels like many labs are pushing toward replacing humans with computers,” she told Gizmodo, “David and I are taking a different approach.” An astrology image generator — combining Co-Star’s UX with Midjourney’s generation capabilities — is already announced as the first joint product.
The Risk: Co-Star’s Users Did Not Sign Up for This
Co-Star has reach precisely because it does not feel like an AI product. Its notifications are blunt, personal, occasionally unsettling. It uses AI and human writers to produce content that feels more like a friend’s brutal honesty than a chatbot’s output. That is the brand. And Gallup data shows Co-Star’s core demographic — Gen Z — is increasingly hostile toward AI: only 22% express excitement about it (down 14 points), while 31% report active anger (up 9 points).
Merging a humanistic astrology app with an AI image company creates friction. Engadget’s headline — “users will surely be thrilled about” — was sarcastic, and not without reason. Guler’s “revealing our humanity” framing is smart positioning, but it is doing a lot of work. Whether Co-Star’s users accept the acquisition or quietly churn to competitors is a genuine question Midjourney will need to answer with execution, not philosophy.
What to Watch
The immediate product is an astrology-focused image generator — using Co-Star’s birth chart data to generate personalized AI imagery. Whether that lands will tell us a lot about how well Midjourney understands its new audience. Beyond that, Holz has described “an ambitious slate of new consumer products,” and this acquisition gives the company the expertise to actually ship them.
Midjourney has done something rare in AI: it built a profitable, high-revenue business without outside capital or platform dependency — until Discord. This acquisition is the first step toward fixing that last vulnerability. If it works, Midjourney will not need Discord, the App Store, or any other platform’s permission to reach its users. That is worth more than any single product it might ship.
Key Takeaways
- Midjourney acquired Co-Star on July 24 — its first acquisition, a clear pivot toward building its own consumer distribution instead of relying on Discord.
- The strategic logic is talent and audience: Co-Star’s 24-person team brings mobile app expertise Midjourney has never had in-house, alongside 4.3 million monthly actives.
- This is part of a broader consumer push — Midjourney Medical (full-body ultrasound scanner), a planned spa, and now Co-Star signal an unconventional but deliberate consumer product strategy.
- The risk is real: Co-Star’s Gen Z users are increasingly anti-AI, and the acquisition introduces brand friction the company will need to manage carefully.
- Watch the first joint product — an astrology image generator — as the early signal of whether this pairing actually works in practice.
