What happened

ecoATM uses a Sierra voice AI agent named Echo to answer the most common inbound customer calls, such as pricing devices, locating kiosks, and general questions, before they reach human support agents.

Summary written by usedby from the source page, in English. The figures are those of Sierra and ecoATM, not ours.

Within the first month, Echo was handling more than 30% of inbound calls—now stably in the mid-30% range, more than double what ecoATM expected. That translated into significant savings.

At the end of the day, we kept coming back to incentives. Sierra is incentivized to solve the problem, and payment is tied directly to resolution.
