For the overwhelming majority of businesses, the answer is buy. Building AI tools in-house only makes sense when the capability is a genuine source of competitive advantage that no vendor sells. For everything else, buying is faster, cheaper and lower-risk.
Buy when (almost always)
- The need is common - customer service, admin, marketing, analysis
- A mature tool already exists for it
- You want value in weeks, not quarters
- You have no in-house AI engineering team
Build only when
- The capability is core to how you win, not a support function
- No off-the-shelf tool fits, even after real searching
- You can fund and maintain it for the long term - build is never "done"
This is the same logic we apply to building versus buying an AI agent: custom is a commitment, not a purchase.
The bottom line
Buy unless the tool is a real competitive edge you cannot buy - then, and only then, build. Making that call well is a core skill in the Generative & Agentic AI for Business Leaders course at London School of Business UK. Enquire today.
