Where it breaks
API and dashboard based; agents are configured and deployed by you or your agency, not built for you by Retell's team.
First entry in this reference. There is no previous check to compare it against.
Retell AI is the build-it-yourself version of the voice-agent category. Where PolyAI sells a finished agent built by its own team, Retell gives you the platform — templates, testing, analytics, webhooks — and expects you or an agency to configure the thing that answers the phone.
That difference shows up in the pricing too: there’s a real self-serve rate, published on the site, rather than a demo gate. Voice runs $0.07 to $0.31 a minute depending on the model and features you pick, chat starts at a fraction of a cent per message, and $10 of free credit gets you testing before you commit a card.
Who this actually suits
Y Combinator backing and the per-minute pricing point at the same audience: agencies building voice agents for local businesses, and developers who want to own the configuration rather than hand it to a vendor. Twenty free concurrent calls is enough to run a small deployment without paying for enterprise concurrency, and the webhook and API access means it plugs into a calendar or CRM you already run rather than requiring you to migrate into someone else’s booking system.
Where the enterprise tier changes things
The jump to Enterprise isn’t about features so much as guarantees — a dedicated server, custom data-processing terms, SSO, higher concurrency. If a regulated business needs those assurances, or call volume outgrows shared infrastructure, that’s the point to have the pricing conversation Retell otherwise lets you skip.
