Acquisition

Midjourney makes its first acquisition, buying astrology app Co-Star

The deal hands the Discord-only AI lab a mobile app with millions of daily users and years of consumer product experience it never built itself.

• Midjourney acquired the social astrology app Co-Star, with the deal reportedly closing in spring 2026 though financial terms were not disclosed.
• Co-Star, used by about 4.3 million monthly active users, combines AI and human writers to produce horoscopes, compatibility reads, and birth-chart-based advice.
• Co-Star founder Banu Guler keeps full control and direction of the app while also becoming Midjourney's chief design officer, leading product, design and frontend teams companywide.
• Co-Star's roughly two dozen employees have joined Midjourney, whose team is now building the company's first standalone apps, including one dedicated to image generation.
• The purchase follows Midjourney's push beyond image generation into ventures like full-body ultrasound scanners for spas, part of eight projects split between hardware and software.
• Buying an app with an established mobile habit and social graph gives a Discord-bound AI lab consumer distribution and product experience it could not build from its models alone.
