Deal breaker
A proven condition that blocks a positive verdict until resolved.
KILL MY IDEA / ADVERSARIAL BY DESIGN
Find the crack before it owns your weekend.
Kill My Idea is not a rejection machine. It searches for the condition that would make the build premature, then turns it into a measurable test, a deadline and a smaller bet.
Kill test
A threshold and time window that can invalidate the core assumption.
Smaller bet
The least expensive version that preserves the learning.
KILL TEST / ILLUSTRATIVE
MARKETTutors will pay to combine booking and deposits.
Test
Offer a concierge setup to 20 independent tutors before writing product code.
Success threshold
Three paid commitments at $15 per month.
Time window
14 days, with a $60 spend cap.
If it fails
Narrow the segment or stop before building a full practice platform.
Smaller bet: run booking and deposits manually for three tutors, then inspect what repeats.
THREE DIFFERENT FAILURE MODES
BUILD
The first version is too large for your actual setup.
Prototype the risky dependency before designing the full workflow.
MARKET
The user pain exists but no concrete commitment appears.
Ask for money, access or behavior before adding more features.
OPERATIONS
The product works only while you perform a hidden service.
Run the manual workflow and measure minutes per customer.
YOUR NEXT MOVE
Do not kill the spark. Kill the expensive assumption.
Start with build reality. The report will show the first condition worth testing.
