Comparison
Build vs Buy: AI Agent Stack
Recommendation thesis
Buy for speed when requirements are standard; build when workflow logic and integration depth are strategic differentiators.
Why now
Buy for speed when requirements are standard; build when workflow logic and integration depth are strategic differentiators.
Time-to-value target for first production release.
What breaks without this
Teams expecting zero operational ownership from either option.
Decision framework
Time-to-value target for first production release.
Need for proprietary workflow orchestration and custom tooling.
In-house capacity to operate and evolve agent infrastructure.
Recommended path
Buy for speed when requirements are standard; build when workflow logic and integration depth are strategic differentiators.
Buy paths often ship 2-3x faster for conventional workflows.
Implementation sequence
Need for proprietary workflow orchestration and custom tooling.
Tradeoffs
Organizations without clear workflow requirements.

FAQ
Is hybrid a valid starting point?
Yes. Many teams start with managed tooling and gradually internalize strategic components.
What should drive the final decision?
Operational constraints, integration depth, and long-term ownership economics should carry the most weight.
