Hey hackers! AI became a thing just 3-4 years ago, and by now we see startups pilled with cash from bigtech giants making 100mln ARR in less than a year with new cool models and application. In this article I tried to summarize data from open source to make a list of the biggest AI companies as by now (December 2025). What’s the methodology behind this? What’s the methodology behind this? This ranking includes only AI-first companies—organizations whose core business model is developing and monetizing their own foundation models (LLMs, multimodal models, code models, image/video generators, or autonomous AI systems). core business model To be included, a company must: To be included, a company must: Sell direct access to its models through subscriptions or API usage
Generate the majority of its revenue from those models
Have a publicly reported or credibly estimated annual recurring revenue (ARR) above $100M as of the second half of 2025 Sell direct access to its models through subscriptions or API usage Generate the majority of its revenue from those models from those models Have a publicly reported or credibly estimated annual recurring revenue (ARR) above $100M as of the second half of 2025 annual recurring revenue (ARR) above $100M I intentionally excluded: I intentionally excluded: Big Tech companies like Google, Meta, Microsoft, Amazon, and Apple, because AI is not their primary revenue driver, even though they produce world-class models.
I also excluded infrastructure providers, consulting firms, and startups that rely solely on open-source models without monetizing their own. ARR data comes from verified reports, executive interviews, investor briefings, and reputable financial journalism—including Reuters, The Information, TechCrunch, and VC research platforms.
