What's an UMM, you ask?
An UMM is a digital employee that works 24/7, fully customized to your needs. UMMs can do bookkeeping, expense reporting, prospecting and much much more.
Isn't that just an AI agent?
It's so much more. AI agents can be kinda dumb. Don't get me wrong: they're very intelligent, but they start off not knowing anything, you have to take weeks to teach them the ropes and then they have the tendency to overengineer, overcomplicate, hallucinate and make mistakes that cost you money (not to mention tokens!).
Our engineers work with you to understand how you work and how to get that work off your plate. We customize the harness and build custom tools for your UMM so that its work is deterministic.
UMMs will notify us of feature requests and of any issues so that they can evolve with your work and operate smoothly without you having to play at being IT support.

Improvement sessions
Four 1-hour sessions with an engineer. Your UMM goes live after the first one, and every session after that upgrades it: new tools, and a tighter fit to how you work.

Run
The monthly retainer covers hosting, monitoring, and ongoing support from our engineers.
Your UMM is live after the first week. Endstation shapes it over four sessions: one of our engineers sits down with you for one hour each week, matching it to how you actually run your business. Every session after the first upgrades it, and by the end of the month you have your very own tried-and-true, trained UMM.
Implementation
An introductory deal for our newest service: it ends November 1.
Your custom UMM, developed over four sessions with an engineer, for half the usual price. You pay 25% up front — and if you aren't getting the value you need at week 4, it's free: we refund every dollar.
Use your UMM for...
Text your UMM “Unit 3 paid $1,200 rent” and it’s recorded, under the right property. Text it an expense, and that’s recorded too. Loans are tracked separately, with interest and principal split out.
No spreadsheets, no software to learn. If you can send a text, you can keep your books.
Our guarantee
If you run into an issue that your UMM doesn't understand, we'll train it, fix it, and build the new tools you need. And if you aren't getting the value you need at the end of your four sessions, it's free: we refund everything you've paid.
