Ann Tarasewicz CEO

Ann Tarasewicz is the founder and CEO of Axis, a multi-product AdTech company building award-winning programmatic infrastructure for suppliers and advertisers. With over nine years in digital marketing and AdTech, Ann has grown Axis from a focused programmatic setup into a full ecosystem operating globally.

Under Ann's leadership, Axis has reached its major technical milestones, including the recent launch of its proprietary Prebid Wrapper (Pubcircle), an in-house SSP for direct trading, and the early development of its own DSP in 2025. These innovations strengthened Axis's control over supply, demand, and data flows, and translated directly into business results. Ann's technical background explains her effectiveness as a leader. She entered AdTech early in her career in Ukraine, working on SDK development and OpenRTB integrations. Rather than following a traditional commercial path, Ann focused on product architecture, a choice that shaped her product-first leadership style. Before founding Axis, she built and scaled advertising products that delivered double-digit growth in CTR, conversions, and company revenue. At Axis, Ann leads a highly technical, globally distributed organization where engineering quality, product architecture, and infrastructure are central to everything the company does. She has helped Axis accelerate its development cycles dramatically, and naturally challenges the notion that leadership and deep technical expertise are separate paths. Beyond the organization, Ann is a recognized industry expert. Her insights on programmatic efficiency, fraud prevention, and the future of AdTech were featured in MarketingProfs, AdMonsters, MarTech, and other leading industry publications, where she advocates for more transparent, sustainable programmatic models.
