Why we built this

Getting paid shouldn't require a $600-an-hour retainer.

The problem

Small disputes get ignored.

Most law firms won't touch a $20,000 invoice dispute — the economics don't work. So businesses eat the loss, and debtors know it.

The insight

An honest read changes the math.

We built AI systems that price risk for insurers and legal teams. The same discipline tells you — fast and honestly — whether your case is worth fighting.

The model

Attorneys where it counts.

Technology handles intake and triage. Licensed attorneys at partner law firms read every case and sign every letter. You get big-law quality at a flat fee.

The pedigree

We've done this before.

Kirkland & Ellis litigation, McKinsey IP strategy, RPX transactions, and risk models backstopping $4 trillion in insured assets — the same people, on your matter.

Find out if your case is worth fighting.

Five minutes to fill out. A straight answer in one business day — even if it's "don't spend money on this."
