FELDMAN ADVISORY · BUILD VS. BUY & TOKEN LEAK CALCULATOR™

Are you building AI—or funding a leak?

Developer hours, bloated context windows, overlapping SaaS tools and fragile prompt chains quietly become a permanent cost structure. Model the next 12 months before you commit another dollar.

The cheapest AI decision today can become the most expensive architecture tomorrow.

Build versus buy is not just a software-price comparison. The real cost includes engineering time, rework, context/token consumption, SaaS duplication, maintenance and the opportunity cost of waiting for the process transformation you actually wanted.

THE FELDMAN TESTIf the current architecture survives for 12 more months, what will you have spent—and what will you actually own?
THE REALITY

Throwing more developer hours at a bad prompt chain doesn't fix the economics. It capitalizes the mistake.

INTERACTIVE AI ECONOMICS MODELER

Model the next 12 months.

01 / DEVELOPER LABOR

How much engineering time is the current approach consuming?

Include vibe-coding, prompt-chain fixes, debugging, integration patching and recurring maintenance.
02 / TOKEN + SAAS LEAK

What is the stack costing every month?

Use current API/model spend plus AI-related SaaS subscriptions and wrappers.
03 / INTENDED TRANSFORMATION

What business process is this architecture supposed to transform?

The technology only matters if it changes an operating outcome.
04 / WHAT WOULD IT COST TO BUILD?

Price the system you actually want.

Model the one-time build plus the recurring infrastructure required to operate it. Token pricing is editable so the calculator stays useful across models and providers.
05 / UNIFIED CONTEXT ALTERNATIVE

What would a cleaner architecture cost?

Model a hypothetical unified context approach: implementation plus ongoing platform/maintenance. These are your assumptions—not vendor pricing.

Stop funding the leak. Underwrite the architecture.

Pressure-test the build-vs-buy decision, context architecture, economics and business outcome before another quarter of engineering and SaaS spend disappears.
