Pricing
Why overpay?
Calls start at 2¢ a minute. You pay what each call costs us, plus a thin margin.
How it works
Cost-plus pricing.
You pay what we pay, plus a 17–25% margin. When our costs go down, so do yours.

Hosting

Our margin
17% of what you pay on lean calls, up to 25% on the most complex.

Example calls at today’s list prices, worked out from measured calls. New agents start on Pro intelligence so their first calls go well. Once real calls show the agent handles them, Zeus can move it to a cheaper setup and tells you what that gives up. Your price depends on your setup.
Our margin
Our thin cut.
We charge a 17% margin on calls that cost us 1¢ a minute or less. It rises gradually to 25% for calls costing us 15¢ a minute or more.
Compare
Calls for as little as 2¢ a minute.
The same calls cost a fraction of a call center, and less than other voice AI platforms.
Why it’s this cheap
We’re bootstrapped and profitable. You reap the rewards.
We aim to be the Costco of voice AI: we succeed through incredible quality at rock-bottom margins. We’re not venture funded, so there’s no investor pushing us to raise prices.
Profitable on thin margins
We can keep margins thin because the business already works.
Vendor price cuts reach you
When a model or voice gets cheaper, your calls do too.
No overpowered stack
Zeus picks the least expensive setup that still gets your calls right.
Cost strategies
Tell Zeus how to spend.
Zeus optimizes every agent for cost using one of three strategies. You can change it any time.
Whatever it takes
2¢, 8¢ or 15¢ a minute for hard calls. Zeus estimates cost from simulated calls, works through it with you, then dials it in on your first real ones.
A hard cap
Set a limit per minute or per call. Zeus finds the best setup under it.
Your unit economics
Optimize for what a call earns you, like conversion value minus call cost.
Voices and phone lines
The rest of the bill.
Pick naturalness, or save.
Platform voices from Inworld cost almost nothing. Premium voices from Cartesia and ElevenLabs add a few cents a minute. Zeus helps you pick.
