Software for work that shouldn't still be manual.

Planned workflow — Rainthorn Field is in private development.
Built for the places field work actually happens.
Basements, mechanical rooms, rural properties, and commercial roofs rarely have dependable five-bar cellular service. A field tool that pauses to load a spinner when signal drops is a tool technicians stop using.
Rainthorn Field is being designed offline-first, so technicians can capture photos, record audio, and review jobs even when the network disappears. Work persists locally on the device, and uploads resume reliably in the background the moment connectivity returns.
Built around real operational problems.
We don't build tech demos or bloated software suites. We build durable tools for teams with real work to do.
Software should remove repetitive work instead of creating another place to type.
Automation prepares the work. People approve consequential decisions.
Rainthorn products are designed to complement the systems businesses already rely on.
Offline workflows, recoverable uploads, audit history, and data ownership are product requirements.
Rainthorn Orders
From customer PO to clean sales order.
Rainthorn Orders is being designed to reduce repetitive order entry for distributors and manufacturers while working with the ERP systems they already use.
"We don't want to replace your ERP. Rainthorn Orders is designed to automate the painful, manual transcription that happens before a clean sales order reaches it."
