The Conversational AI Ecosystem

The companies, products, and technologies shaping the future of conversational agents.

Conversational AI Ecosystem — Updated April 2021

Conversational AI is a fast-growing industry with a number of start-ups and established companies offering a wide variety of products and services for an even wider variety of customers.

We compiled, reviewed, and curated nearly 200 companies and technologies, created one big list and categorized them in several ways to try to help understand what’s taking place in the space:

Builders vs. End-Users

As we started reviewing the various companies and their offerings it became clear there were broadly two classes of offerings: those companies that offer technologies for builders: Developer Platforms vs. companies that offer products and services for enterprise end-users: Enterprise Platforms.

Developer Platforms

Within the builder category, there are several types of companies most of which tend to be closer to the machine learning software itself and designed for software developers or product analysts. Within the builder category, these are the high-level categories of offerings:

Enterprise Platforms

For companies that are looking to leverage conversational AI as a service or to directly solve a business problem, there are different classes of companies:


As mentioned in the previous blog, we found interesting domain-specific bots in the following areas: finance & insurance, health & medical, HR & recruiting, restaurants, and contact centers & customer service. Because of the volume of activity and interest in the area, we’ve also included sales and marketing/lead generation as another domain-specific area. Some sectors, like education, make use of bots substantially but primarily leverage customer service and general-purpose bot platforms, rather than industry-specific bots.

Follow the Money

As you may have read from the first article in the series, this is a big space with huge market potential.

Players in this space include the big F-MAGA companies — Facebook, Microsoft, Apple, Google, and Amazon — that invest heavily in natural language processing, speech, and conversational AI R&D for a wide variety of technologies and tools across the spectrum of ASR, NLP, bot builder services, intelligent virtual assistants and more. We’ve referred to this category as Big Tech — and they have virtually all developer and enterprise offerings.

And while investment funding is not the best indicator of the success of a company, it is one quick way to get a sense of how investors see the possibilities and expected value in the future of the space. The list of companies compiled includes a number of private companies who, according to Crunchbase, have over $5 billion in aggregate private investment and VC funding (as of the publication date of this article).

Here’s a visualization that shows how the companies break down in terms of funding and focus area:

The List

We’ve also included a link to a google sheet containing the list of companies, URL, funding (if available and found on Crunchbase), category, industry, and some news articles about the companies. We’ve done our best to collect, curate, and categorize the companies and technologies but if you have any feedback or corrections you’d like to suggest, please let us know.

* Update Apr 9, 2021: We updated the google sheet with several companies that were shared with us. We also updated the ecosystem image at the top of the post. I don’t expect we’ll do another update of the image itself anytime soon — but we’ll do our best to keep the google sheet updated.

This article is part of a series on conversational AI and includes contributions from Leonardo Cordoba. Please check out the start of the series here.

The next article will describe how to build your own Chatbot or VoiceBot.
