Active projects cluster around experiment design, model deployment, and algorithm refinement for campaign performance, while pain points (client churn, bidding strategy optimization, campaign launch delays) reveal friction between product velocity and operational execution. Sales-led hiring (6 of 14 open roles) combined with data and support functions reflects a revenue-focused org navigating both product-market fit challenges and scaling customer success.
