For most companies, buying or partnering is the right choice for non-core AI capabilities. Building is reserved for strategic differentiators. The AI tool market has matured. High-quality off-the-shelf solutions exist for most functions.
Build
When to build: AI capability is a core strategic differentiator, you have proprietary data that gives a unique advantage, off-the-shelf solutions don't meet requirements, you have the talent and resources
Cost: High ($150–300K+ annually for data scientists. Expensive ML infrastructure)
Time: Slow (6–18 months for meaningful capabilities)
Control: Full | Risk: High (AI projects have high failure rates)
Buy
When to buy: Capability is not a strategic differentiator, off-the-shelf solutions meet 80%+ of requirements, speed to deployment is important, you lack the talent to build
Cost: Medium ($10K–$500K annually depending on scale)
Time: Fast (weeks to months)
Control: Limited (dependent on vendor roadmap) | Risk: Medium (vendor lock-in, data privacy)
Partner
When to partner: Need customization beyond off-the-shelf but lack internal talent, want to build internal capability over time with external support, AI use case is complex and requires domain expertise
Cost: Medium-high (consulting fees + technology costs)
Time: Medium (3–9 months)
Control: Shared | Risk: Medium (partner dependency)
The Decision Matrix
| Factor | Build | Buy | Partner |
|---|---|---|---|
| Strategic importance | High | Low | Medium |
| Proprietary data advantage | Yes | No | Maybe |
| Internal AI talent | Strong | Weak | Weak |
| Speed requirement | Low | High | Medium |
| Budget | High | Low-Medium | Medium |
| Customization need | High | Low | Medium |

Key Takeaways
- Build for strategic differentiators. Buy for commodity capabilities.
- The AI tool market has matured. High-quality off-the-shelf solutions exist for most functions.
- Partnering bridges the gap between buying and building for complex, customized deployments.
- Proprietary data is the primary reason to build rather than buy.
- Start with buying. Build only when off-the-shelf solutions are insufficient.
