$4.2M Annual "Ghost Tax"

This is the $4.2M 'ghost tax' in action. It's the silent killer of developer velocity, costing you millions in onboarding delays and production incidents.

How We Find the Truth

1

DIAGNOSIS

APX analyzes your API's current state against its documentation.

2

REPORT

It identifies every undocumented behavior, dependency, and drift.

3

PREVENTION

APX provides a living source of truth and can continuously monitor for future changes.

The Chasm Between Documentation and Reality is Widening.

Four market forces are making the problem worse every single day

📈

API Explosion

API complexity is growing 3x year-over-year.

👥

Knowledge Drain

30% of senior engineers—and their tribal knowledge—left their jobs last year.

🤖

AI-Accelerated Chaos

AI is generating 55% more code, but documentation is falling further behind.

⚖️

Regulatory Pressure

New SEC rules require incident disclosure in 4 days. You can't afford surprises.
