El coste de nuestro equipo de atención al cliente estaba aumentando entre un 300 y un 400 por ciento al año. Al introducir Retell y crear a Lucas, pudimos reducir esa carga en más de un 50 por ciento, mejorar drásticamente nuestros márgenes de SaaS y seguir dando soporte a nuestros clientes durante situaciones de alto crecimiento y urgencia.
