Build it, or buy it?
The honest answer is rarely “whichever is cheaper.” Model the three-year total cost of building versus buying, weigh whether this is core to how you win, and get a recommendation that accounts for both — not a spreadsheet that ignores maintenance and strategy.
What does each path really cost?
Estimates are fine. The point is to make the hidden costs — maintenance, time-to-value, strategic lock-in — visible next to the sticker price.

The catch: —
The wrong build is the most expensive line on your roadmap.
Whether each piece of your stack should be built, bought, or retired — and whether what you own actually fits your data and team — is AI Stack Fit, one of six dimensions in the Readiness Index. See how well your stack fits the way you actually operate.
How to make a defensible build-vs-buy decision for RevOps AI tools
The pitch from every vendor is that their tool will transform your operations in weeks. The pitch from your engineering team is that they can build it better in-house. Both are partially right. This modeler gives you a structured analysis instead of gut feel.
Enter your specific numbers for vendor licensing, implementation costs, engineering hours, and ongoing maintenance. The tool models three-year total cost of ownership for both paths and weighs strategic fit factors: vendor lock-in risk, data portability, customization flexibility, and whether the capability is a competitive differentiator worth owning. The output is a defensible recommendation you can present to leadership.
Who this tool is for
RevOps and engineering leaders evaluating whether to buy a vendor solution or build in-house. Product teams deciding whether a GTM capability should be part of the platform. Anyone presenting a build-vs-buy business case to a CFO who wants numbers, not opinions.
How to interpret your results
The recommendation is not just about which path is cheaper. A build recommendation means the use case depends on proprietary data, the capability is a differentiator, and your engineering team has capacity. A buy recommendation means the vendor has domain expertise you lack, speed to value matters, and the use case is common enough that building would reinvent the wheel.
