Linus

What Linus does

Linus Labs, Inc., operating as Linus, is an Oakland, California-based SAT preparation company founded in 2024 that delivers an adaptive, AI-powered test prep platform for high school students. The product combines a 4,300+ question expert-written content library with an AI Tutor for 24/7 contextual help, 10+ full-length adaptive practice tests calibrated to the College Board's Digital SAT scoring logic, real-time score predictions, a personalized dashboard tracking strengths and weaknesses, and gamified daily goal-setting. Native mobile applications are available on iOS (4.9 stars) and Android (4.8 stars), with cross-device progress sync, and the platform reports 100,000+ students have used the service.

Linus monetizes through a single subscription product priced at $99 per month or $499 per year, with billing processed via Stripe and a money-back guarantee tied to score improvement outcomes (250+ points for starters below 1200; 1450+ for 1200-1440; 10+ for 1450+). The company operates a product-led growth motion targeting individual student consumers via website, app stores, and word-of-mouth, complemented by an institutional channel for schools, tutoring centers, and nonprofits seeking group pricing. Linus is privately held, employs 1-10 people, is backed by Owl Ventures (which led a $5M round announced April 3, 2025), and uses PostHog for product analytics.

The company has no disclosed revenue figure, no management team bios in the source material, and no patents or published research. Strategic posture is early-stage consumer SaaS in edtech: narrow product focus on SAT, broad feature surface within that focus, capital-backed scaling runway from a single named institutional investor, and an institutional channel in build-out mode as a potential second growth vector.
