Stilta

Active

Overview

Stilta is a Swedish applied-AI company developing agentic software for patent and intellectual-property work. Its platform searches and analyzes patents, scientific literature, and archived web sources for workflows including freedom-to-operate, invalidity, infringement, prior-art research, and claim mapping. Outputs are designed to be source-cited and auditable for review by patent attorneys and in-house IP teams.

The company occupies a specialized position in legal and intellectual-property technology rather than general-purpose AI. Its notable feature is the use of multiple task-specific AI agents to conduct research and organize evidence at scale, while leaving legal judgments to professionals. Publicly identified customers include major IP firms and Fortune 500 companies, although a complete customer list is not disclosed.

History

Stilta was founded in 2026 by a team of four engineers with backgrounds at McKinsey and QuantumBlack. The company entered the market through Y Combinator's Winter 2026 cohort and initially focused on patent litigation and related intellectual-property analysis. It later reported a $10.5 million seed round led by Andreessen Horowitz, with participation from Y Combinator and operators from OpenAI, Legora, and Lovable. Stilta IP AB is registered in Stockholm under company number 559568-6196.

Reputation

Stilta is presented by early customers, startup databases, and the company as a specialist platform for auditable AI-assisted patent work. Its perceived strengths are source citation, coverage across patent and technical datasets, and workflows tailored to professional IP users rather than generic document summarization. The company is early-stage, so independent long-term assessments of accuracy, legal reliability, adoption, and cost remain limited. AI-generated analysis still requires attorney review, particularly for high-stakes legal decisions.
