Each one started with a person and a problem: a spreadsheet nobody could keep up, a tool that didn't exist, a machine nothing could be installed on. Some are open to look at; some sit behind a sign-in or on someone's own computer.
Operations software
Operators dashboard
A wastewater plant's daily dashboard
An activated-sludge plant's lab readings lived in one spreadsheet per day. Now operators enter them once and the dashboard does the rest: SRT, sludge settling and blanket depths as they type, alarms when a basin drifts, tomorrow's wasting rates and pump timers, and every day since 2023 in trends. It runs on one laptop with no install, no admin rights and no network.
Marina operations
A marina, run from one app
A demo on a made-up 164-slip marina in Annapolis, on real tides and weather, written for the people on the docks. The day comes as a list with one big button per job: see off, check in, call the captain, mark the haul-out done. The docks are drawn from above, with each boat in its slip; tap one to act on it. Bookings only offer slips the boat fits, and the owner's numbers read as a few plain sentences. Try it: book a boat in, it resets each night.
Run a marina, a boatyard or a rental fleet? This is a starting point: I'd connect it to your slips, billing and staff.
