"Olivier Silvestre is one of the best practitioner/consultants in the entire web analytics industry and has been a thought leader for almost as long as we've been measuring sites.  Olivier's soft-spoken style is balanced with his deep understanding of the relationship between business and measurement, and few of his clients have ever expressed anything but a great respect for his ability to positively impact their bottom line.  In the six years we have known each other it is safe to say that he has taught me as much or more than I have taught him.”
