Mercor and Anthropic: AI Startups' Revenues Soar

A Rapid Surge in Revenue for AI Startups

In today's technological landscape, startups specializing in artificial intelligence (AI) are experiencing revenue growth that exceeds expectations. These companies, whether new or already established, are seeing their revenues not only increase but do so at an increasingly rapid pace, reaching financial milestones in record time.

Varied Definitions of ARR

The startups mentioned here all exhibit exponential revenue growth, but it is crucial to understand that the term "ARR" (Annual Recurring Revenue) can have different meanings depending on the companies. Some use this term to refer to annualized recurring revenue, while others speak of contracted revenue that has not yet been billed. There are also those that calculate annual revenue projections based on the most recent month's revenue, or refer to "committed ARR," which means signed contracts that have not yet been activated. For example, Gusto reports its actual revenue over the past 12 months.

Mercor: Impressive Growth

Mercor, a young company less than three years old, recently announced that it reached a gross annualized revenue of $2 billion in June, just four months after surpassing the billion-dollar mark. This company, which specializes in recruiting experts to train and refine AI models, also reported reaching a rate of $500 million in September.

Anthropic: Captivating Numbers

Anthropic, a manufacturer of AI models, has also experienced spectacular growth. At the end of May, the company announced it had reached $47 billion in annualized revenue, a milestone achieved in less than two months after surpassing $30 billion. The company also stated it expects to reach an annualized revenue of $9 billion by the end of 2025, up from $4 billion in July 2025.

Sierra: A Quick Leap

Sierra, which develops AI agents for customer service, reached its first $100 million in ARR in seven quarters. However, it took only two additional quarters to add another $100 million to that figure, according to co-founder and CEO Bret Taylor.

Glean: Notable Acceleration

Glean, an AI startup for enterprises, crossed the $300 million mark in ARR in May. While it took nine months to double its ARR from $100 million to $200 million, it managed to go from $200 million to $300 million in just six months.

Gusto: Continuous Growth

Gusto, an HR tech company founded 14 years ago, has seen its revenue accelerate over the past five quarters. The company, valued at $9.3 billion at the beginning of 2022, surpassed $1 billion in revenue over the past 12 months, demonstrating that the integration of AI is also benefiting older companies.

Clio: The Impact of AI on the Legal Sector

Clio, a provider of management software for law firms, has seen its revenue soar after integrating AI into its services in 2023. The company surpassed $200 million in ARR by mid-2024, doubled that figure by the end of last year, and recently announced it has reached $500 million in ARR.
