It solved one narrow and repeated task that every company has at the end of each quarter: find all invoices and give them to the accountant.

It reads every line item instead of only the total, which matters for travellers with receipts in foreign scripts and currencies.

It sold one promise that a customer can measure: a first reply to every new lead within 10 seconds, to businesses that already pay for many leads through Meta ads.

They placed it inside the help desks that customers already pay for, and priced it below the AI agents that the help-desk vendors sell themselves.

The one published customer, Interline Hardware, says the reorder list now takes about 30 minutes a day instead of three hours.
