Operations founder seeking technical co-founder for B2B drone marketplace

The Idea
DroneHire is a B2B marketplace connecting commercial drone pilots with enterprise clients who need aerial data for construction, agricultural mapping, real estate, and infrastructure inspection. It streamlines pilot sourcing, airspace compliance, scheduling, and large dataset transfer.

Who It's For
Enterprise clients who need reliable licensed drone operators, and commercial drone pilots who want a better way to find and manage work.

What's Built
High-fidelity wireframes and a mapped-out user journey. No product built yet.

Early Traction
Spoke with dozens of commercial drone pilots and enterprise customers. Pain point is verified — they are actively losing time and money on scheduling and unreliable pilots.

Their Background
Non-technical founder with a background in operations and sales. Has spent the last few months on market validation, ICP mapping, and building out compliance and regulatory frameworks.

What They Need
A technical co-founder to own the full architecture and roadmap — full-stack marketplace development, data architecture for heavy file handling and photogrammetry/LiDAR pipelines, and early-stage velocity. Equity split with standard vesting.
