the larger market overlooks.
Xentinel Studios is a small workshop building quiet, considered software for industries that fall outside the usual roadmaps — managed-services firms, member clubs, shooting and archery ranges. We publish one new product per quarter, when the work is ready.

/01Xentinel MSP
An autonomous platform that repairs itself — before the user notices.
Xentinel MSP runs as a quiet operator across a fleet of machines. Detects, diagnoses, applies safe repairs without a human in the loop. The AI layer studies trends and predicts failures a day or two ahead. The dashboard is for the rare moments a human needs to intervene.
- ✓Self-healing rules run 24/7 — disk cleanups, service restarts, security re-enablement
- ✓Predictive alerts 24–48 hours before failure, with remediation pre-written
- ✓Per-client portal — tickets, assets, invoices, service reports
- ✓Live fix terminal — watch the AI diagnose & repair in real time

/02Range Keeper
The administrative backbone of a small club, made quiet.
Members, dues, range and event booking, member SMS — built with the patience of a club secretary who has done this by hand for fifteen years. Replaces four spreadsheets and a group text with one calm interface built for volunteer boards.
- ✓Member roster with online renewals, life memberships, exemptions
- ✓Range & event booking — by lane, by hour, no phone tree
- ✓Dues, accounting and exports the treasurer can actually use
- ✓SMS sent under the club's own brand — not ours

The studio
We build software the way a small press publishes books — with editorial intent, in measured runs.
A workshop of three, operating quietly out of Boston. We pick a vertical the rest of the industry doesn't bother to map, listen carefully, and ship a product that fits the people who use it. Then we tend to it for as long as the audience needs us.
