• Conduct regular one-on-one meetings, provide continuous feedback, and manage the team's professional development.

Client Onboarding & Strategy:

• Act as the primary representative of the integration team during the client onboarding phase. The onboarding process involves preparing the client after the sales phase and monitoring them for a 30-day trial period before handing them over to the CSM team.

• Develop and define strategic ad placement plans (plan de tag) for new clients to maximize their performance.
• Prepare and present data-driven analyses and performance reports to key clients, defending strategic recommendations.
