Omnichannel AI agent platform for customer service, built on Sendbird's communications APIs, with persistent long term memory across chat, voice, SMS, email, and social.

Sendbird is an omnichannel AI agent platform for customer service, built on top of the communications infrastructure that already powers in app chat, voice, and video for thousands of the world's largest apps. Founded in 2013 in San Mateo by John Kim, Harry Kim, Brandon Jeon, and Forest Lee, and shaped in Y Combinator, the company pivoted from a social app for parents into a developer chat API and raised about two hundred twenty million dollars, reaching a one billion dollar valuation with its one hundred million dollar Series C in March 2021 led by ICONIQ, alongside SoftBank Vision Fund, Tiger Global, and Y Combinator. Its infrastructure routes billions of messages a month across more than four thousand applications including DoorDash, Match Group, and Noom.

In November 2025 Sendbird launched Delight.ai, a strategic pivot from communications plumbing to AI agents that resolve customer issues rather than just carry messages. The platform deploys personal AI agents across chat, voice, SMS, email, and social, and its central bet is persistent long term memory that carries context across every interaction instead of the reactive one shot behavior of a typical chatbot. AI Concierge and Omnipresent AI meet customers wherever they are, a Voice AI Agent handles spoken conversations, AI Agent Integrations wire agents into existing systems, and Agent Steward, added in May 2026, drives autonomous issue resolution end to end.

Because Sendbird grew up as a developer platform, it brings deep extensibility, with communication APIs and cross platform SDKs for iOS, Android, JavaScript, React Native, and Unity, plus HIPAA compliance for regulated apps. The agent layer is new, so some governance and evaluation tooling is still maturing relative to its mature messaging core. For a product or support team that already thinks in APIs and wants AI agents embedded natively across every channel with real memory, Sendbird is a strong option; a small team wanting a turnkey help desk without engineering involvement may find a packaged support tool simpler.

Integrations

Offers communication APIs and cross platform SDKs for iOS, Android, JavaScript, React Native, and Unity, plus business messaging across SMS, WhatsApp, mobile push, in app, and KakaoTalk. Delight.ai adds AI Agent Integrations that wire agents into existing systems, and the platform is HIPAA compliant for regulated applications.

In practice

Your chatbot forgets everything the moment a conversation ends, so customers repeat themselves constantly. Sendbird's agents keep persistent long term memory across chat, voice, SMS, and email, so every interaction builds on the last.

Support is fragmented across a web widget, an app, SMS, and social, each with its own bot. Sendbird deploys one AI concierge that follows the customer across all of those channels with shared context.

You want AI agents embedded natively in your product, not bolted on. Sendbird's communication APIs and SDKs let engineers wire agents into the app directly, with Agent Steward resolving issues autonomously end to end.

Pricing

Free developer tier; paid chat plans start in the hundreds of dollars a month on usage, with Delight.ai agent products quoted through sales

monthly active users, message volume, and AI resolutions

Public — partialHigh variable costFree tierTrial available

What is public

Chat and messaging plans publish usage based tiers with a free developer tier, but Delight.ai agent pricing is quoted through sales.

Billing mechanics

Usage based billing on monthly active users and messages for the communications platform, plus AI resolution or agent based charges for Delight.ai.

Cost watchouts

AI agent resolutions and premium channels such as voice and SMS carry their own usage costs on top of the base messaging subscription.

Variable cost rationale

Core pricing is metered by monthly active users and message volume, and the agent layer adds AI resolution costs, so spend scales directly with audience size and interaction volume.

Additional watchouts

Monthly active user based billing can climb fast for consumer scale apps, and the agent products are priced separately from the messaging core.

Sales call required

Mixed (some tiers require a call)

Free / trial

Free developer tier and trial; paid plans and agent products above

Key ambiguities

Delight.ai agent pricing is not published, so the cost of the AI layer requires a quote.
