For me, working with Whistle freed a lot of time from my hands. Now I can focus on what requires me—meeting the customer and converting opportunities—not driving them. The customer service is very, very good, and the people at Whistle are true professionals. They bring a lot of domain knowledge to the table, and the conversations are always productive and focused on optimizing performance. We’re very happy with the collaboration so far
