AI product startup building
proprietary consumer apps.
Halo Labs is an early-stage AI product startup building and operating its own proprietary consumer products. AstroHalo is our first product, currently in private beta.
A technology startup building original AI-powered applications.
Founded in 2026 in South Korea, Halo Labs is focused on building proprietary consumer software products that combine deep data models, modern mobile UX, and AI personalization. Our mission is to transform complex frameworks into accessible, premium user experiences.
We operate as an independent product studio. We do not provide outsourced development or client services. Every piece of software we ship is 100% owned, designed, built, and operated in-house by our core team.
Engineering-led product design.

AstroHalo
AI-powered astrology platform that delivers professional-grade chart analysis to everyday users through personalization.
Domain Architecture: AstroHalo is the flagship proprietary software of Halo Labs. While Halo Labs (halo-labs.dev) serves as our corporate headquarters and B2B portal, our consumer-facing application and product validation operate entirely on its dedicated domain (astro-halo.com) to provide the best end-user experience.
The Problem
Existing astrology apps rely on generic sun-sign content. Users who want real chart analysis are stuck with expensive consultations or confusing software built for professionals.
