Sunder did not name direct agency competitors during the interview. He referenced several software tools as alternatives to one another, including ClearScope and Razer as alternatives to Surfer SEO, and Byword and Withdream as programmatic SEO infrastructure tools. These are tool comparisons, not agency competitor disclosures.
Sunder did reference SEMrush in the context of TripleDart's own programmatic SEO results, noting that TripleDart's location-targeted pages rank number one or number two for B2B SaaS SEO agency queries in multiple U.S. states, appearing above or alongside SEMrush in search results. This is a search-ranking observation by Sunder, not a confirmed figure from SEMrush.
