Loopwright moved from seats to per-loop pricing with a hard cap. Quantum Billing counted every look at a loop as another loop.

“We moved from seats to per-loop pricing with a hard cap. Quantum Billing applies the cap after billing. Customers call this transparent, in the support thread.” Ada Nwosu, COO, Loopwright

Loopwright sells an AI coding agent. It reads your repo, writes a fix, runs the tests, notices the fix broke something and writes it again.

Seats broke when one engineer ran the agent 10,000× as much as the median. Ada's plan was to bill per loop, add a hard spend cap as an entitlement, and add outcome pricing later.

Quantum Billing meters loops, un-loops and observations of loops. Reviewing a diff observes the loop, so checking the agent's work counts as usage.

The spend cap is an entitlement, so it resolves on view. The cap is real, but it is applied after billing.

Outcome pricing charges when a suggestion is accepted, and acceptance is decided after billing. In the public support thread, customers called this transparent.
