Fernstone is an AI-powered insurance brokerage for businesses. We are competing with the 40K insurance brokers that sell $500B in commercial premium each year.

Luke led a Growth team, closing some of Traba’s largest customers like JB Hunt and Kimberly Clark. Bryant, James’ classmate from high school, was a Software Engineer at Sentilink and Google.

The Problem:

Every business buys insurance at some point.

But, the process of finding coverage remains frustratingly analog. Insurance brokers call, email, and even fax carriers for quotes. That back and forth is both manual and slow.

One customer told us he waited 6 weeks for his broker to find him construction insurance. In that time, he lost a major deal.

The Solution:

We are building the fastest and most effective insurance brokerage in the world. We combine AI with licensed brokers-in-the-loop to review and bind coverage.

Our AI agent automates the manual back and forth, tracking email threads, and instantly following up.

We find insurance for complex risk faster, and instantly issue documents like COIs.

Our Team:

We experienced this problem while working at Traba (Series A warehouse staffing startup). There, our insurance brokers rarely picked up the phone when we needed coverage for injured workers.

Luke and James met at Traba when they started on the same day. Luke led a growth team, closing some of Traba’s largest customers like JB Hunt. He was previously Head of Growth at Antimetal and co-founder of Contrast (acquired).

James created Traba’s enterprise function and grew it to 25% of company revenue. He was previously BCG, UChicago, and a former debate champion ranked #1 in the US.

Bryant, James’ friend since high school, was a software engineer at Sentilink (Series B) and Google. He previously acquired and operated a raffling company with a friend, and 2x’d profits by building new tech tooling.
