Arnaud Wiart — Customer Success Manager

With 7 years of sales and customer success experience in the IT sector (Observability, Cybersecurity, Data, and Telecoms), I have developed solid expertise in driving customer-centric value strategies and managing complex sales cycles. My international career across London, Paris, and Barcelona has enabled me to thrive in multicultural environments and advise executive stakeholders on critical technological challenges. What I bring to organizations: > Strategic Project Steering: Managing a $4M+ ARR portfolio (Dynatrace) and leading 24+ post-sales implementation projects within 6 months (OneTrust). I bridge the gap between technical operations and C-Level expectations across diverse industries (Luxury, Banking, Retail, Manufacturing). > Retention & Churn Mitigation: Proactive risk identification and execution of targeted action plans. Result: Achieved a record 99.85% renewal rate over 3+ years at Dynatrace. > Data-Driven Expertise: Leveraging my Data Analyst background, I translate complex technical data into strategic business insights focused on product value and ROI. > Sales ADN & Results-Oriented Culture: As a former Account Executive and SDR, I master the full sales cycle and growth levers (Upsell/Cross-sell) within innovative SaaS ecosystems. Based in Barcelona for 3 years, I am dedicated to driving high-impact post-sales strategies and fueling the growth of innovative SaaS players by combining analytical rigor with a strategic business vision.
