What is Fearn?
Fearn positions itself as the startup-first patent firm, with the tagline Big Law patents, startup speeds. It combines former Big Law patent professionals with its own technology so startups can file patents faster and at lower cost than traditional firms.
According to The SaaS News, Fearn hosts proprietary models optimized to resist hallucination and meet specific legal requirements, which lets users turn disclosure materials into filing-ready drafts in minutes. The company frames its mission around the global first-to-file patent system, where speed matters, and it aims to serve both solo researchers and enterprise R&D teams. Customer quotes on its website describe getting a strong first draft over a weekend and being able to afford a full portfolio for what a single patent used to cost.
Fearn was founded in 2025 by Han Kim and Angela Gao and is based in San Francisco. In June 2026 it announced a $5.5M seed round led by Kindred Ventures, with participation from a16z speedrun, Designer Fund, and Essence VC. The company said it would use the capital to expand its purpose-built patent models and product capabilities.
