Six Live Chat Tools and the Bubble That Runs Your Website

You have talked to all six of these companies without ever knowing their names. The little box that slides up from the bottom-right of a website, asks if it can help, and blinks with three animated dots while someone types - that box is a product. Somebody builds it, prices it, and sells it. And it turns out there is not one way to build it. There are at least six, and each one is a different bet about how a business should talk to a stranger.

HelpCrunch, WATI, Pure Chat, LivePerson, Rocket.Chat and Provide Support all live inside that same corner of the screen. From the visitor's side they look nearly identical. From the inside they could not be more different - in age, in customer, in business model, and in what they think the bubble is actually for. Line them up and you get a surprisingly clear map of how customer support quietly became a software category worth billions.

01 — THE ELDERLivePerson invented the thing everyone copied

Start with the oldest. LivePerson was founded in New York in 1995 by Robert LoCascio - first as Sybarite Interactive, building a community platform called TOWN, before pivoting to the idea that would define it. In 1999 the company filed the first patent on live chat and took itself public a year later. LoCascio is still there, one of the longest-standing founding CEOs in tech.

Today LivePerson does not chase the corner store. It sells a conversational AI platform called the Conversational Cloud to enterprises - HSBC, Orange, GM Financial, The Home Depot - and counts more than 18,000 customers. The bubble it started with has grown into automated virtual assistants that route millions of conversations. It is the reference point every other name on this list is implicitly measured against.

02 — THE CHANNEL BETWATI moved the bubble onto WhatsApp

Bianca Ho and Ken Yeung started together in 2016 building Clare.AI, an enterprise AI assistant for large Asian companies. Then they made the opposite bet. In 2020 they launched WATI - short for "WhatsApp Team Inbox" - a low-code, self-serve tool that lets small businesses run support and marketing through the WhatsApp Business API.

The insight is simple and it travels well: in much of the world, customers already live inside WhatsApp, so support should meet them there rather than drag them to a website widget. That focus paid off. WATI reached roughly $9.6M in revenue and, in 2022, raised $23M led by Tiger Global. Where LivePerson owns the enterprise web, WATI owns a channel.

03 — THE OPEN ONERocket.Chat gave away the code

Rocket.Chat exists because of an accident. In 2015, four developers in Porto Alegre, Brazil - Gabriel Engel, Rodrigo Nascimento, Marcelo Schmidt and Diego Sampaio - were building a CRM and tried to bolt a live chat widget onto it. Looking at the code, they realized the widget could be something much bigger. They rebuilt it in JavaScript and Node.js, put a prototype on GitHub, and watched it go viral on Hacker News and Product Hunt.

The result is one of the largest open-source communication platforms around: self-hostable, so organizations that care about data privacy or compliance can keep every message on their own servers. That model attracted real money - a $19M Series A in 2021 and a $10M bridge round in 2024 that helped triple the team and grow users five-fold. Its pitch is ownership. The bubble, but on your infrastructure.

04 — THE BUNDLEHelpCrunch sells "stop paying for five tools"

HelpCrunch takes a different angle entirely. Instead of one great feature, it sells a package: live chat, chatbot, a knowledge base, popups, and automated email marketing, all in a single shared inbox. The pitch is arithmetic. Rather than paying separately for chat software, an email platform, and a help desk, a small business gets them bundled, starting around $12 per team member per month.

It is the classic SMB move - reduce the number of tabs a small team has to keep open. For a startup that cannot afford a dedicated support stack, one subscription that does live chat, self-service and lead capture is an easy yes.

05 & 06 — THE QUIET ONESPure Chat and Provide Support keep it simple

Not every company on this list wants to become a platform. Pure Chat was founded by Hamid Shojaee in 2012 with a modest premise: help entrepreneurs and small teams have better conversations with leads. It raised $1.5M in seed funding, powered more than 39 million chats, and in October 2020 was acquired by Ruby to slot into a broader customer-connection offering.

Provide Support may be the quietest of all. Its live chat system launched in August 2003 and has run continuously since, serving thousands of clients in more than 100 countries. No megaround, no pivot to a buzzword - just a reliable widget that keeps working. In a market that reinvents itself around every new trend, longevity is its own kind of feature.

THE THROUGH-LINEA short history of a small box

The bubble is older than the web. Its earliest ancestor ran on the PLATO computer system at the University of Illinois, decades before anyone thought to put a "chat now" button on a storefront. Live chat entered business in earnest around 2002-2003, right as LivePerson's patent was fresh and Provide Support was switching on its service. Everything since has been a variation on the same question.

What separates them is not the widget. It is everything behind it. LivePerson bets on enterprise scale and AI. WATI bets on a channel. Rocket.Chat bets on ownership. HelpCrunch bets on the bundle. Pure Chat and Provide Support bet on staying small and dependable. Every one of them is now adding chatbots and AI assistants that answer the easy questions and hand off the hard ones to a human. The bubble that started as "is there a person there?" is turning into "is there a person there when I need one?"

Which one is right depends entirely on who you are. A solo founder does not need a Conversational Cloud; a global bank cannot run on a $12 widget. That is the quiet lesson of the whole category: the smallest interface on the internet is not one product. It is a market disguised as a button.
