Kustomer is a customer service CRM that throws out the ticket and rebuilds support around the person. Every conversation, order, and interaction lands on a single customer timeline, and its AI agents draw on that full history to answer personally, handling order status, changes, and refunds across email, chat, voice, SMS, WhatsApp, and social. It comes in two flavors that share the same no-code studio: an autonomous agent that resolves customer questions end to end, and a copilot that drafts and summarizes for human reps. Native AI Voice means the phone channel is built in rather than bolted on.
The company's history is a genuine plot twist. Kustomer was founded in 2015 in New York by Brad Birnbaum and Jeremy Suriel, the same duo who had earlier built Assistly, which Salesforce bought and turned into Desk.com. Meta then acquired Kustomer in a deal valued around a billion dollars, and about fifteen months later spun it back out to its original investors at roughly a quarter of that price, a rare corporate un-acquisition in which Meta even kept a minority stake. The deliberately misspelled name has stuck through all of it.
Now independent again, Kustomer raised fresh funding led by Norwest in 2025 and pushed its AI-native platform forward with automation and observability tools that trace exactly how an agent reached its answer. Pricing runs on annual seat tiers with an eight-seat minimum, plus a conversation-based option that unlocks unlimited users, and its autonomous agent is billed per engaged conversation.
Brands like UNTUCKit report meaningful productivity gains from putting the whole customer, not just the ticket, in front of every agent. If you believe support should feel like an ongoing relationship rather than a stream of disconnected, context-free cases, Kustomer's CRM-first approach is built from the ground up for exactly that.

Zendesk AI agents resolve customer requests autonomously across email, chat, messaging, and voice, and they have the advantage of sitting on one of the most widely used support platforms on earth. Because they are built into Zendesk's help desk, the agents draw on your knowledge base and years of past tickets to answer questions instantly, then hand off to a human with full context when a conversation needs one. Zendesk also threads AI through the agent workspace itself with a copilot that suggests replies, detects intent, and summarizes long tickets.
The lineup comes in two flavors. The Essential tier bundles friendly generative answers into the Suite, while the Advanced tier, built on Zendesk's acquisition of Ultimate, goes fully autonomous, working off-script and calling your APIs to actually get things done. In keeping with where the industry is heading, the Advanced agents are billed per resolution, so you pay for issues solved rather than seats filled.
There is a fun irony in Zendesk's origins. The company was founded in 2007 by three friends in a Copenhagen loft who wanted support software that felt human instead of clunky, and its deliberately approachable branding helped it grow into an industry giant, go public, and later get taken private in a deal worth roughly ten billion dollars. More recently it has been on an AI shopping spree, absorbing companies to bolt voice, quality assurance, and deeper automation onto the platform.
Real customers put it to work in colorful ways: cosmetics brand Lush named its Zendesk agent Marvin and uses it to resolve a large share of first contacts. For the enormous number of teams already running support on Zendesk, switching on its native AI agents is often the shortest path of least resistance to real automation, with no new vendor to onboard and no data to migrate.
