Own what makes you different. Rent what doesn't.
Anyone who tells you to cancel every subscription is selling you something. Anyone who tells you to keep them all is selling you something too. The useful question is which ones.
Two kinds of software
Every tool your business pays for falls into one of two groups.
The first group does a job that's the same for every business on earth. Taking a card payment. Hosting a video call. Keeping the books. Delivering an email to an inbox. These are commodities: enormous companies do them extremely well, at prices that keep falling, and nothing about how your business does them makes you different from anyone else. Rent these. Always. Building your own payment processor is how you go out of business.
The second group is the part of your business that is your business. How you sell. How a stranger becomes a member. What the member experience is. How coaching gets booked and delivered. What your team sees when they open the back office in the morning. This is the layer where your judgement, your offers and your way of working live — and it's the layer most businesses rent, from platforms built for the average customer, at prices that rise every year.
Why this is backwards
Renting a commodity is cheap because the vendor sells the identical thing to millions. Renting your custom layer is expensive for exactly the opposite reason: the platform has to be bent into your shape, and you pay for the bending twice — once in the subscription and again in every workaround, every second login, every offer you didn't launch because the checkout couldn't do it.
And you never finish paying. A commodity gets cheaper over time. A rented custom layer gets more expensive, because the vendor knows leaving is painful.
The rule
So: own what makes you different, rent what doesn't. Stripe handles the money. Zoom handles the calls. Your accountant keeps their software. Everything that touches what your members experience and how your business actually operates — that's the part worth building once and owning outright.
Apply the rule to your own stack and you'll find it splits cleanly. Three or four cheap commodities that stay. Three or four expensive platforms that are all, in different ways, renting you the same thing: your own business, shaped to their template.
What "own" has to mean
Owning is only worth anything if it's real. The code in your account, in your name. Standard technology any developer can work on. Documentation. A recorded walkthrough. Data in open formats. A maintenance arrangement you can end any month without losing a thing. If any of those is missing, you've rented something with a longer contract. Here's the version I put in writing.
Want the rule applied to your actual stack, line by line? That's the Stack Audit. $500, credited against the build — and it will tell you which subscriptions to keep.
