The annual Digital 100 ranking for 2025, released today by the leading digital market intelligence experts at Similarweb (NYSE: SMWB), celebrates the companies that demonstrated the most significant digital growth in the US, UK, France, Germany, Japan, Australia, India, and Brazil.
“Every year, the Digital 100 allows us to celebrate companies achieving tremendous growth within highly competitive sectors of the digital economy,” said Or Offer, CEO and founder of Similarweb. “The Digital 100 report is a powerful tool to help organizations understand and elevate their performance in the digital world.”
The awards are organized around industry categories plus a Big Winners category that identifies the major players producing continued growth. The report identifies the fastest-growing websites and the cross-platform Digital Winners exhibiting web and app growth. For the first time, the US and UK editions of the Digital 100 provide an equal depth of coverage for the 100 fastest-growing mobile apps and websites. The reports for France, Germany, Japan, Australia, India, and Brazil name a shorter list of app winners.
While the winners varied by country, one recurring player was ChatGPT, OpenAI’s generative AI chatbot, which was #1 in the Big Winners category for France, #3 in Australia, #4 in the UK, and #9 in the US. Substack was also identified as a cross-platform Digital Winner in the US (among the Big Winners) and the UK (among News & Media websites and apps). Particularly in the US and UK, the Big Winners category was dominated by News & Media websites, often with a distinct partisan tilt. Look for more detail in the individual country reports listed below.
“In many cases, the #1 website and #1 app in a category belong to different companies, reflecting the distinct strategic roles each platform can play,” said Marta Su?kiewicz, VP Global Research Solutions at Similarweb. “For digital products and services, apps and websites often serve complementary purposes across customer acquisition, engagement, monetization, and retention. Ali Express managed to excel at both web and app growth in the UK, Germany, and Australia, earning our cross-platform Digital Winner award in those countries.“
The categories vary by country, but for the US and UK include Apparel & Accessories, Beauty & Wellness, Consumer Electronics, Food & Drinks, Gaming, Home & Garden, News & Media, Personal Finance, Travel & Tourism.
