Konstantinos Antzakas

·     I apply the discipline of competitive sports to Revenue & GTM Operations, merging top-tier performance habits with precise business execution.

·     As a partner to Revenue leaders and a comprehensive GTM domain expert, I supported ARR growth from $250M to $500M by driving sales efficiency, segmenting for value, and implementing predictive forecasting models.

·     With roots in Business Intelligence and Data Engineering, I build actionable frameworks to support data-driven decision-making, whether it’s designing sales velocity dashboards in Tableau or embedding customer health scores in Gainsight.

·     A certified OKR coach, I help teams drive cross-functional alignment and prioritize effectively, establish sustainable rhythms, to improve operational efficiency, and streamline GTM systems, delivering measurable gains in sales productivity and deal quality.

·     From campaign redesigns with Marketing, which increased win rates +50%, to onboarding improvements in Customer Success to achieve an +80% renewal rate, I deliver results that move the revenue needle.

·     I approach my work like a business owner, driving results with urgency, ownership, and high standards.
