The Merlin/Leonard Essentials training proved to be indispensable to our on-boarding on the solution. Sylvain knew how to popularize and dedicate Marketo, which is very powerful but extremely complex, especially when it comes to setting up the tool. Sylvain allows us to save a precious time at each of his interventions and reassures us about our initiatives, before their implementation. Sylvain’s dual marketing/technical skills are a real plus and we consider him more of a partner than an integrator. I can only recommend Merlin/Leonard if you are embarking on the Marketo adventure.
