Build vs Buy AI Agents: Strategic Enterprise Choices

Build vs. Buy: The AI Agent Conundrum

"By 2028, agentic AI will power 33% of enterprise software," Gartner projects. That's a staggering number. It suggests a seismic shift in how enterprises will operate. But here's the kicker: do you build these agents or buy them?

Let's cut to the chase. If you're a financial services firm, healthcare company, or consulting firm where AI is merely a tool, buying is generally faster and cheaper. Bastien Hontebeyrie from CMI Strategies mentions that monthly costs of 30-40 euros per consultant can generate massive time savings. That's ROI that any CFO would love.

The Case for Building: Flexibility and Differentiation

Building your own AI agents offers unparalleled flexibility. It's about creating a system that's uniquely yours. If your aim is enterprise-wide workflows or differentiated business value, building might be your best bet. This gives you the freedom to create agents that not only solve problems but do so in a way that underscores your competitive advantage.

Take, for example, a retail company wanting to create a personalized shopping experience. Off-the-shelf solutions might not capture the unique nuances of their customer base. Building an AI system in-house allows them to tailor every interaction, turning customer data into actionable insights.

The Hybrid Approach: Build + Buy

For those sitting on the fence, a hybrid "build + buy" model offers a middle ground. Buy a basic AI platform and build custom integrations and workflows on top. This approach speeds time-to-value while reducing risk. You get the benefits of a proven system and the flexibility to tailor it to your needs.

Consider a logistics company that buys a generalized AI solution but layers on custom algorithms to optimize routes in real-time. They've essentially built a unique capability on a stable foundation.

Measuring ROI: More Than Just Cost Savings

In 2026, companies that see the most significant ROI from AI agents will measure value not in reduced headcount but in new revenue streams and resilience. It's not just about cutting costs or improving efficiency; it's about creating new opportunities.

Take customer service. AI can resolve up to 80% of queries, cutting costs by 30%. But the real magic happens when these agents drive upsells, cross-sells, or even open new business lines.

What's Your Strategic Priority?

The decision to build or buy ultimately hinges on your strategic priorities. If your business model thrives on differentiation and you have the resources to invest, building might be worth the effort. If you're looking for speed and cost-effectiveness, buying could be your best move.

Whichever path you choose, the goal should always be the same: using AI to drive meaningful business outcomes.
