Founding cohort · By application
ArbKeep is opening to a small founding cohort of working arborists. Run it in the field, tell us where it falls short, and keep every dollar of your book. Free for your first 90 days, then $39 a month — locked as your founder rate. We onboard a few at a time, deliberately.

The second door · Heartwood
Most of the cohort simply runs ArbKeep in their practice. A few also help build it — that's Heartwood, the guild shaping the tool from inside the work. Four lanes, one filter: everyone here arbors.
The moat is the shape of the data. Bartlett and Davey have the labs and the PhDs — but their data is jobs and contracts, not a living per-tree record that follows the property and outlives the customer. A service company can't grow that layer from the inside. ArbKeep is the record itself — append-only, conversation-native, AI-reasonable — the substrate the whole field runs on next.
If that makes you want to open a PR, this is your lane.Chat is the primary surface, not a feature. One bubble grammar — photo, lab panel, diagnosis, invoice — worn two ways by Pro and homeowner from a single render. The craft is making a medical record feel like a text thread.
Designed once, felt differently.A true story (the first health record for trees), a real wedge (the work was never dispatch and invoices), and an industry no one has spoken to like this. The product is the story — and it isn't vaporware.
Tell it like you've held the saw.Field judgment is the spec. The diagnoses, the soil work, the credential ladder — you set the standard the software is built around, while running your own practice and keeping every dollar of it.
You set the bar. We build to it.Apply
