How Hafen's SSG cut booking admin from 30 minutes to 30 seconds with Lockii
Building Hafen's SSG
Anyone who has ever taken a car to a shop knows the feeling. Shop fees, labor charges, surcharges, and a fix that does not always hold. Nathan Curtis built Hafen's SSG for the people who would rather do the work themselves, calling it the hobbyist revolt against all of that.
Hafen's is a self-service garage. Instead of paying a mechanic, customers reserve a lift or floor space by the hour and get access to a professional shop with over 1000 tools on hand. They stay out of the elements, work at their own pace, and only pay for the time and space they use.
Why did Nathan start it? His answer is refreshingly honest: to make money. A great rental business does not need a complicated origin story. It needs a real demand, a smart model, and a way to run it without drowning in admin.
Why Nathan chose Lockii
The model was clear, but the tooling was not. An hourly self-service garage is a tricky thing to run. You are handling time-based reservations, payments, and building access, often outside of normal business hours, and most booking software is not built for it.
Nathan searched for a long time and kept hitting the same wall. In his words, he could not find a system that fit his needs until he found Lockii. Everything else was either too generic, too manual, or missing the pieces he needed to run his business while working his full-time job.
Lockii fit the shape of the business. Online booking by the hour, automated payments, and self-serve access meant Nathan could offer a true 24/7 experience without standing at the door for every customer.
What changed after moving to Lockii
The numbers tell the story. Admin time per booking dropped from 30 minutes to 30 seconds. That is not a tweak, it is a completely different way of running the shop.
The whole workflow is now automated. Customers reserve their lift or floor space, pay, and get what they need to access the shop, all without Nathan working the booking by hand. The parts that used to eat half an hour each now take care of themselves.
That leaves Nathan with a very short to-do list. As he puts it, Lockii manages everything, so all he has to do is collect the money.
Lockii is the perfect fit for my hourly rental business. It manages everything for us, so all I have to do is collect the money.

What comes next for Hafen's SSG
Nathan is not thinking small. His long-term goal is to rent self-service mechanics garages in all 50 states, taking the hobbyist revolt nationwide.
With admin down to seconds per booking and the workflow running itself, that kind of expansion becomes realistic. The same automated model that runs one shop can run the next one, and the one after that, without adding hours of manual work each time.
