21X

21X, from Structurely, runs AI agents that handle inbound and outbound conversations by voice, SMS, RCS, email and chat. Businesses use it to qualify leads, answer questions, schedule appointments and route calls around the clock.

Agents qualify, answer, transfer, schedule and escalate customers based on intent, context and business rules, and follow up across channels until a conversation reaches an outcome. Teams can use it out of the box, go headless with the API, or mix both.

Billing is a platform fee plus token-based usage, with voice from $0.07 per minute when you bring your own carrier and SMS and AI email from $0.02 each. Onboarding covers platform setup, agents, integrations, telephony and workflows.
