Build vs Buy Analysis

Stop guessing on TCO.

Evaluating whether to build in-house or buy a SaaS product shouldn't be a religious debate. Score maintenance costs, licensing, and engineering effort objectively.

End the "Not Invented Here" syndrome.

Engineers naturally want to build. Finance naturally wants to save. Force both sides to look at the mathematical reality.

Subjective Evaluation

  • × "We could build that in a weekend" (It takes 6 months)
  • × Ignoring the ongoing maintenance cost of internal tools
  • × Ignoring the vendor lock-in risk of SaaS
  • × Decisions based on engineering ego or procurement budgets

Objective Evaluation

  • Total Cost of Ownership (TCO) is calculated exactly
  • Long-term maintenance burden is factored into the score
  • Vendor risk and lock-in are weighted appropriately
  • Unbiased, data-driven conclusions that satisfy both sides

Engineering Reality

Force engineers to explicitly score the ongoing maintenance burden, server costs, and opportunity cost of building internally.

Vendor Risk Analysis

Score SaaS vendors on data portability, lock-in risk, and integration effort to ensure you aren't trading engineering debt for vendor debt.

Executive Alignment

Present leadership with a clear, indisputable matrix showing exactly why buying the software is cheaper over a 3-year horizon.

You're haunted by the "we can build it in a weekend" lie.

You've heard it before. An engineer claims they can replicate a $20k/year SaaS tool over the weekend. You agree. Two years later, that internal tool has consumed hundreds of thousands of dollars in engineering salaries, it's constantly breaking, and the single engineer who understands the code just resigned. The frustration of repeating this cycle—trading clear software costs for hidden, catastrophic maintenance debt—is maddening. You need a way to force everyone to see the true cost.

Axiom Decision Agent

"We need to decide whether to build an internal billing system or buy Stripe Billing. We need to evaluate Year 1 implementation cost vs Year 3 maintenance cost."

Generated: TCO Build vs Buy Matrix

Criteria: Year 3 Maintenance (High Weight), Integration Effort (Medium Weight), Feature Velocity (High Weight).

Unbiased evaluation models, instantly.

When the debate gets religious, you need an impartial framework. You simply tell Axiom what you are trying to build versus what you are trying to buy. The AI generates a comprehensive TCO (Total Cost of Ownership) matrix. It automatically includes the hidden criteria everyone forgets: opportunity cost, long-term maintenance, and security compliance. It forces the debate out of the realm of ego and into the realm of rigorous, inescapable math.

Rational capital allocation.

Imagine sitting in the architecture review meeting. Instead of an argument, you look at the Axiom matrix together. The math clearly shows that building internally will cost 4x more over three years when maintenance is factored in. The debate ends immediately. You sign the vendor contract with confidence, and your engineering team stays focused on your core product, not reinventing the wheel. Total operational clarity.

5 minutes to decision-ready.

Stop building evaluation spreadsheets from scratch. Describe your problem, and Axiom will instantly generate the exact framework you need to align your team.
