At Office Nomads we are 100% coworking memberships. This is for a couple key reasons. We want a model that is simple to manage, simple for our members, that deemphasizes the financial transaction and helps us maintain a sense of "home". I have seen many other models that achieve a similar "feel" and come at the challenges in different ways. For us, simplicity is our primary strategy. We could introduce additional revenue streams with events, private offices, or add-on services, but we choose not to. This helps us stay focused as we are less scattered. It also allows us to have weekends which is essential.
And finally, we intentionally don't call it "rental" as that undermines the real value of our membership. I know wording can be a tricky beast filled with nuance, but another benefit of our tight focus is that we can take the time to evaluate how people respond to the various marketing angles people take. And since we rely on one source of income it's very important we get this right... for the market we are looking to bring in.
