Build vs Buy vs Subscribe
Subscribe to prove value and for commodity capabilities; buy/integrate for workflows specific to your business; build only where the capability is a durable competitive advantage. The mistake is building what you should rent, or renting what should be your moat.
The question that decides it
Ask whether the capability sits on your critical path to winning. If owning it buys no advantage, rent it. If it is specific to how you win, own the workflow. Ideology does not enter into it.
A rented workflow can be shut off, repriced, or copied by every competitor on the same subscription. That is fine for a commodity capability and fatal for the process that is supposed to be your advantage. Map each capability to how much competitive edge ownership buys, and let that, not cost alone, drive the decision.
The pragmatic sequence
Most businesses should subscribe first to prove value cheaply, then build the specific workflows that become durable advantage once the value is proven. This limits downside while preserving the upside of ownership.
- Subscribe to prove the use case works, at minimal upfront cost.
- Once proven, decide if the workflow is core to how you win.
- If it is, invest in owning it; if not, keep renting and move on.
Frequently asked questions.
When is building your own AI actually worth it?
Only when the capability is a durable competitive advantage that owning protects, a workflow specific to how you win that you do not want every competitor renting from the same vendor. For everything else, subscribe or integrate.
