The build-vs-buy decision for enterprise AI is rarely binary. Most enterprises end up with a mix: buying commodity capabilities, building differentiating ones, and assembling pre-built components for everything in between. The art is knowing which approach fits each use case.
When to Buy
Buy when the capability is commodity (OCR, speech-to-text, basic NLP), when speed-to-market matters more than differentiation, and when your team lacks the specialised skills to build and maintain the solution. Buying a pre-built MCP platform with 50+ connectors is almost always cheaper than building connectors from scratch.
When to Build
Build when the capability is a core differentiator (proprietary recommendation algorithms, custom risk models), when the data is too sensitive for third-party processing, or when no commercial solution meets your specific requirements. Building should be a strategic choice, not a default.
When to Assemble
Assemble when you need custom workflows built from standard components. Pre-built AI agents from a marketplace, connected through MCP, customised with your semantic layer and governance rules. This gives you 80% of the speed of buying with 80% of the flexibility of building.
The Total Cost Question
Building looks cheaper in year 1 (no license fees) but costs more in years 2-5 (maintenance, updates, infrastructure, team salaries). Buying looks expensive in year 1 (license fees) but is predictable. Always calculate 3-year TCO — including the cost of the team needed to maintain what you build.
