About Fieldmark

A Pinal County crew
built to cover every acre.

Fieldmark started where it still lives, between cotton rows, solar racks, haul roads, and fairways in central Arizona. We fly the DJI Agras T100 and back it with a vetted operator network when the window gets tight.

Why we exist

We watched the spray window close too many times.

Fieldmark exists because Arizona operators, growers, asset managers, mine engineers, and turf managers, keep losing days they can't afford to lose. Wet ground. Tall canopy. Closed holes. A ground rig in the shop. A manned pilot booked three weeks out.

We started with one aircraft, one phone number, and a simple promise: a real plan back in 48 hours, every acre documented, no upsell. As demand grows we scale through a vetted operator network, not by overstating the badges on our wall.

The Founders

Two operators. One standard.

Joshua Brown

Co-Founder · Brand & Growth

San Tan Valley, Arizona

Joshua brings a rare combination of production-agriculture roots and modern brand strategy to Fieldmark. Raised on a multi-generational family farm in Western Kentucky working tobacco, cattle, and row crops, he was running his own tobacco operation before finishing high school. Twelve years of hands-on farm work gave him a working command of the calendars, margins, and equipment realities that growers live by.

He is the founder of Soulheart Ventures, a portfolio of privately held companies spanning leadership, marketing, technology, and e-commerce. At Fieldmark, Joshua leads branding and go-to-market strategy and runs field demos that show growers exactly what the equipment can do. He has been flying drones since 2016 and holds his FAA Part 107 Remote Pilot in Command certification.

Joshua lives in San Tan Valley, Arizona with his wife, Laura, and their three children.

How We Operate

Four rules. Every job.

Document Everything

Every flight ends with a coverage map and an application record. If we can't prove it, we didn't do it.

Operator-First

We were customers before we were a service. We build the experience we'd want from our own vendors.

Local Before Loud

Pinal County is home. We earn AZ before we expand anywhere else.

Honest About Status

Our pilots hold their FAA Part 107. Part 137 commercial applicating and our Arizona Dept. of Agriculture license are in progress, and we say so, every time.

Ready When You Are

Built local. Flown clean. Documented.
