Pay as you go

You stay in control of spend

Set your limit

Cap how many minutes you run through Zelto each month, so your spend never runs past what you set.

Filter what counts

Analyze only the calls that matter to you, and filter out the ones you'd rather we skip.

Never overpay

The moment a higher plan would cost you less at your volume, we tell you to switch.

Built for voice agents. Catch. Fix. Measure.
