01
RegisTeam Verified
Founded in Kyiv in 2015, RegisTeam is a growth marketing agency that works with clients in the United States, Europe and Australia. Its work is built around two disciplines that carry most of its projects: search engine optimization and pay-per-click advertising, with CRM consulting and analytics supporting both. On the SEO side, the team handles technical audits, content and link building, and a newer line of work on visibility in AI search — making sure brands are cited in answers from ChatGPT, Google AI Overviews and similar tools. On the paid side, it plans and manages Google Ads accounts, from launch and tracking setup to ongoing optimization. CRM and automation projects connect marketing data to sales, so lead quality can be measured rather than guessed. According to its Clutch profile, RegisTeam has delivered more than 1,300 projects in over 25 countries and holds a 5.0 rating across 69 client reviews.
