Leo Umanskiy

Leo Umanskiy is the founder of CLOSR Limited, a B2B agency growth consultancy. He reports scaling three digital agencies beyond $50,000 a month and advising more than 150 agency owners — credibility built by scaling his own agency to roughly $600,000 a year at 19, then restructuring it after growth started costing him his freedom.

Leo studied Psychology at Oxford Brookes University (2022–2025), a background that shapes how he approaches marketing, copywriting, consumer behavior, sales conversations, and objection handling. His first business was online fitness coaching — about six to seven months of work for roughly $40. A close friend introduced him to GoHighLevel, and after three to four months learning the platform, he launched a B2B marketing agency.

By his account, roughly a year and a half of intensive work scaled that agency to approximately $600,000 in annual revenue at age 19, without outside funding. But the business became demanding in ways that ate into his social life, family time, mental health, and personal time — the freedom the agency was supposed to buy him was the thing it quietly took away.

He rebuilt around that lesson. CLOSR Limited operates a structured done-with-you/done-for-you consulting model — which Leo says runs at roughly 93% profit margins — built on the Meta ads, LinkedIn, Instagram, outreach, sales, fulfillment, and retention systems he developed scaling and then restructuring his own agency. Reported professional experience includes work with Current Consulting Group and Noble Fitness, and fractional strategy roles for AI-Clinics and Medspa CEO.

Leo's Gateway Growth conversation covers objection handling as accountability rather than pressure — holding a prospect to the goals they already said they wanted, without becoming pushy or manipulative.
