Unprofitable customer
A customer whose LLM cost exceeds the revenue they pay you.
On flat pricing these appear naturally as usage rises: the customer keeps paying the same price while their token bill climbs past it. Spotting them early lets you cap usage, move them to a higher plan, or change pricing.
Why it matters
Every unprofitable customer turns growth into a liability — more signups make the problem bigger, not smaller. Finding them early is the difference between a pricing tweak and a crisis.
Example
A $29/mo customer whose usage drives $34 of LLM cost is unprofitable by $5 every month — and on a flat plan, nothing stops that usage from climbing further.
