For CEOs and CTOs of Series B and Series C SaaS companies
Neutralize the upcoming cost crisis your reports can't see.
Success changed the rules. The architecture didn't.
The product found its market as one system: any part could change at any time, decisions in one room, features in days. That was the right way to find the market. Every feature since tied more of the product together. A change that should touch one part now drags others with it: more hours, more risk. Defusor measures that extra cost, on the product you already ship.
Defusor turns git data into engineering overspend metrics and a cost-cut plan.

You can see the people.You cannot see the extra hours.
You already know what the team costs. Headcount and salaries land every month. The extra hours a change takes, once it drags other parts of the product, do not. They hide in incidents, meetings, and rework, so they never become a number you have to decide about.
Strategy does not change in time as you scale.
Your hire plans measure people. They do not measure the cost of keeping the old shape while the market moves. Components of the product, the boundaries between them, and the teams that own them stay as they were. Inadequate boundaries let a change in one part drag the others. That misalignment is what produces the overspend.
What happens
- Market and customers evolve
- Product structure falls behind
- The product becomes infeasible
The engineering org already feels this.
You already feel this in the org. Velocity goes down while the calendar fills with meetings and reporting. More people are hired to deliver the same outcomes. Tighter management, more reporting, and more hiring are the next steps that make sense. They do not take the extra hours away, because they do not change how the product is put together.
Symptoms
- velocity down
- more meetings
- more reporting
- hire more to ship the same
What often comes next
- micromanagement
- more reporting
- overhiring
Defusor shows where engineering cost goes.
It maps spend to the work: what is expensive, why it got expensive, and what that work should cost instead. Built for the CEO or CTO who needs a clear picture before the next headcount plan or process layer.
Examples from a test company.
Surface the patterns.
The scan surfaces business, product, and tech patterns that point to overspend signals.

GitHubread-only
Your CTO connects GitHub once. Nothing to install.

Patterns
AI agents read how the product changes and price the extra hours each change takes.

Plan
You get the cost picture and a cost-cut plan, as a PDF every quarter.
During the scan, Defusor stores inferred data produced by AI agents.
What used to be an invisible business killer is now measurable.
Measure the overspending. Then change what made it expensive.
