Fernstone
AI-native commercial insurance brokerage for fast-growing small businesses
Overview
Fernstone is an AI-native commercial insurance brokerage serving fast-growing small businesses in construction, security, and logistics. The company focuses on the USD 1,500-15,000 premium segment, a range many traditional brokers and carriers find unprofitable to service directly.
The brokerage places general liability, workers' compensation, and specialty and professional lines across a panel of nine or more carrier partners. Each client is paired with a licensed risk advisor who reviews and binds coverage, while an AI agent handles carrier-facing administrative work such as email follow-up, renewal tracking, and certificate issuance. Fernstone reports serving more than 300 businesses as of 2026.
Fernstone was founded in 2025 and launched publicly in February 2026 through Y Combinator's Fall 2025 batch, following a USD 1.5M pre-seed round in January 2026. Co-founders James Chen and Bryant Le previously worked at Traba, BCG, SentiLink, and Google.
