Lo mejor de Sizle.io es saber quién ha visto una presentación, en qué diapositivas se ha fijado y durante cuánto tiempo.
El equipo de ventas estaba asombrado de poder "ver" qué diapositivas estaban revisando los clientes en tiempo real.
Sizle.io superó nuestras expectativas cuando vimos cómo un cliente se implicaba con nuestra propuesta.
Entender cuándo, dónde y cuánto participan los destinatarios de nuestros mazos nos ayuda enormemente en el seguimiento".
