Our experience working with Will was outstanding. From the very beginning, Will took time to understand our needs, map out a new process, and deliver a custom configuration. Will is personable, patient, and technically very capable. He navigated some niche asks with ease and was proactive about suggestions. We now have a CRM that truly fits our business with clean data, meaningful workflows, and a flexible architecture that scales. Thanks Will!

The more we worked with Will, the more we learned what Attio could do. And the more our project grew arms and legs. Will took it all in his stride and delivered us an amazing structure to build on for the future.

Working with Will on our Attio CRM setup was such a great experience. He really took the time to understand how our team works and what we needed from the system - not just the technical setup, but how it would actually make our day-to-day easier. Thanks to his help, we now have a CRM that actually fits us and we feel confident using it. I’d happily recommend Will and Sideways to anyone looking to implement Attio or get more out of their CRM.

As a smaller company, no one had the bandwidth to give this project as much attention as it deserved, particularly considering how much we were trying to customize and the short timespan we had in mind. Will really excelled at taking as much or as little direction as we could give him and turning it into something that exceeded our expectations. In a very short period, we're using Attio in ways I would never have expected to make our sales motion significantly more effective.
