The list of the world's 20 most profitable AI Agent companies is out, with the top one raking in up to $500 million. Two trends are worth paying attention to.

Recently, data institution CB Insights released a highly - regarded list: "The top 20 AI Agent startups with the highest global revenues."

This list is different from traditional rankings that rely on financing amounts or valuations. Instead, it ranks companies directly by their real revenues. It can be said that it is the most direct window to observe the commercial implementation capabilities of the AI Agent track.

There are also many well - known names among the listed companies: from Cursor, a programming assistant for developers, to Harvey, which serves the legal teams of Fortune 500 companies; from Clay, which automates sales lead generation, to Fyxer, a personal AI assistant embedded in email. These companies not only represent the most cutting - edge exploration directions of AI Agent commercialization but also have clear monetization paths in their respective vertical scenarios.

Through this list, we can see two clear trends:

First, AI Agents are evolving from tools to "digital employees". They are no longer just assistants that answer questions but intelligent individuals capable of independently completing tasks and even being responsible for the results. They are starting to truly take over core business processes such as sales, legal affairs, customer service, and coding.

Second, revenue is becoming a new threshold for measuring the competitiveness of AI startups. After the era of "storytelling", the companies that can enter the revenue - generating stage faster will have more say.

Next, let's take a look at which 20 AI Agent companies have rushed to the forefront of global revenues with their real commercial implementation capabilities.

01 Cursor, AI Programming Agent (ARR: $500 million)

Cursor develops an AI - based "vibe coding" programming editor, which is an IDE integrated with an AI assistant. It can perform functions such as auto - completion, multi - line intelligent refactoring, code completion, and code library query. It can also detect logical and security vulnerabilities introduced by AI or humans in real - time through Bugbot.

Currently, there are more than 360,000 paying users, and hundreds of millions of lines of code are generated daily. Its customers include Stripe, OpenAI, Spotify, Midjourney, etc.

In May 2025, Anysphere just completed a $900 million financing round, and its valuation soared more than three times compared to the beginning of the year to approximately $9 billion. As of now, Anysphere's ARR has reached $500 million, and each employee generates $3.205 million in revenue.

02 Glean, Enterprise Search Agent (ARR: $100 million)

Headquartered in Palo Alto, California, Glean positions itself as a "Work AI platform". Its core business is enterprise - level work search + AI agent functions.

04 Replit, AI Programming Agent for Developing Apps with Natural Language (ARR: $100 million)

Replit is an Agent that can develop apps and websites based on natural language. It can not only write code but also handle all matters from setting up the environment to deploying applications.

Replit was born out of a core pain point: the high entry threshold for programming. The traditional software development process is cumbersome and complex. Developers need to configure an integrated development environment (IDE), install the runtime environments of various programming languages, manage dependency packages, and understand how to deploy programs to the server. This series of preparatory work often discourages many people interested in programming.

The founders of Replit acutely captured this pain point and put forward a grand vision: to make software development interesting and accessible. To achieve this goal, Replit is committed to building a one - stop development platform that integrates all the tools required for programming in a browser - based environment. This means that users don't need to make any local installations or configurations. They can start coding immediately by opening a browser, selecting the required programming language or template.

This "zero - configuration" development experience has greatly lowered the programming threshold, making Replit one of the most user - friendly integrated development environments on the Internet.

According to previous news, Replit is in talks with investors for a new round of financing, and its valuation is expected to nearly triple to $3 billion. Currently, the company's ARR is $100 million, and each employee generates $637,000 in revenue. It is worth mentioning that Replit only took 6 months to increase its ARR from $10 million to $100 million.

05 Lovable, The Fastest - Growing Agent in History (ARR: $100 million)

Lovable is an AI startup headquartered in Stockholm, Sweden. It is committed to enabling users to build complete web applications without coding through natural language prompts. Users only need to describe their ideas, and Lovable can generate applications with a front - end interface, back - end logic, and database support in a few seconds. (For details, see: "The Fastest - Growing AI Company in Europe! Lovable Achieved $120 million in Revenue from Scratch in Just 3 Months")

As one of the fastest - growing companies in the AI field in terms of commercialization, Lovable took only 8 months to reach an ARR of $100 million. The per - capita revenue is as high as $2.222 million, and its latest valuation is $1.8 billion.

06 Crescendo, AI Customer Service Agent (ARR: $91 million)

When encountering complex disputes, real - life experts can quickly intervene with the help of the conversation context sorted out by AI. They can even retrieve the user's return and exchange records and shopping history from three months ago to achieve precise services.

In terms of business models, Crescendo has also abandoned the traditional customer service billing model based on the number of people or hours and adopted a result - oriented pricing model. With its innovative model and payment method, Crescendo has achieved an ARR of $91 million, and its latest valuation is $500 million.

07 Harvey, AI Legal Agent (ARR: $75 million)

StackBlitz keenly observed that few developers build web applications within the browser. To address this issue, they launched WebContainers technology, enabling web - based application building.

This means that StackBlitz has opened up another channel for application development. From now on, software development is no longer the exclusive domain of traditional developers. Anyone can create their own software without learning programming and code.

In January 2025, the AI programming company StackBlitz completed a new round of financing, with the financing amount exceeding $100 million. At the same time, the company announced that the number of registered users had exceeded 2 million.

Hebbia is committed to building AI software for the finance and legal industries, providing high - level knowledge work organization services for companies through data and information organization.

In professional service fields such as financial services, law, and consulting, the ability to effectively find information is particularly important. Many investigation processes require manual analysis of a large number of dense documents.

At the beginning of 2025, Hebbia recently completed a $130 million Series B financing, led by Andreessen Horowitz, with participation from Index Ventures, Google Ventures, and Peter Thiel.
