We wanted to non-linearly scale our sales calling efforts and decided to use Retell. We made over half a million calls in a short span of time with nearly no engineering bandwidth used. Truly remarkable product!

In terms of outcomes, we've achieved a 20% conversion to lead in a user segment we previously found challenging and didn't expect any conversions from, so we weren't reaching out to them before. We're delighted with the results, which have exceeded our initial expectations by five times.
