# TerraClear Inc

> TerraClear builds AI-powered machines that take one of farming's oldest, most miserable chores - picking rocks out of fields - and make it fast, precise, and increasingly autonomous. Founded in 2017 by serial entrepreneur and farm-raised Brent Frei, the Issaquah, Washington company pairs drone-based mapping, machine vision, and a robotic rock picker that clears hundreds of rocks an hour. In 2026 it launched TerraScout, a fully autonomous field-scouting robot that scans up to 1,000 acres a day for rocks, weeds, and more, turning images into real-time prescriptions for existing farm crews and equipment.

- **Founded:** 2017
- **Headquarters:** Issaquah, Washington, United States
- **Founders:** Brent Frei (Founder & Chairman (former CEO of Onyx Software, co-founder of Smartsheet))
- **Team size:** ~52 employees
- **Products:** Rock Picker (TC100), Rock Map, TerraScout, Weed Management
- **Notable:** Built the first holistic AI rock-management system combining drone mapping, machine vision, and a precision robotic picker., Raised roughly $53M total, including a $25M Series A led by Madrona Venture Group., Grew toward ~1,000 customers and weekly service across thousands of acres.

## Products & services

- **Rock Picker (TC100)** — A precision robotic implement that mounts to a skid steer, compact track loader, or tractor and removes an average of 400 (up to 600) rocks per hour, lifting rocks up to ~300 pounds with minimal soil compaction.
- **Rock Map** — Drone-captured, high-resolution imagery processed by AI/neural networks to map the exact location and size of problematic rocks in a field, accessible via TerraClear's mobile app.
- **TerraScout** — A fully autonomous field-scouting robot launched in 2026 that collects ultra-high-resolution imagery (4+ billion samples per acre), maps 1,000+ acres per day at up to 15 mph, runs ~6 hours per refuel, and uses onboard edge compute to turn images into real-time mission plans for rocks, weeds, and more.
- **Weed Management** — AI-powered identification and management of weeds using the same machine-vision and mapping technology stack built for rock detection.

## Achievements

- Built the first holistic AI rock-management system combining drone mapping, machine vision, and a precision robotic picker.
- Raised roughly $53M total, including a $25M Series A led by Madrona Venture Group.
- Grew toward ~1,000 customers and weekly service across thousands of acres.
- Launched TerraScout in 2026, described as the first fully autonomous robot for real-time field prescriptions in large-acre row crops.
- Demonstrated up to 8x labor efficiency - one customer cut a 4-day, 6-worker rock job to 1 day with 3 workers.

## Latest updates
