Wilhelm Rahn named Surfly (spelled S-u-r-f-l-y) as the primary competitor in the co-browsing space, describing it as the main player in the industry. Rahn did not provide a revenue figure for Surfly and acknowledged he did not have the number available. His characterization of Surfly as large was based on the company's web crawl footprint, specifically the number of website installs detectable through common SaaS intelligence tools, though he did not state a specific install count during the interview. No other named competitors were discussed. Any characterization of Surfly's size reflects Rahn's stated opinion and is not a company-confirmed figure.
