Organized, efficient, and accommodating of our ambitious customization schedule

Jane Camp, Meridian
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.
Exactly what we needed

Will is great. When we were cutting over from Hubspot to Attio, we just wanted someone to make sure we weren't missing anything. Will took our base objects and made our data actionable and meaningful; along with helping button up our reporting and automation. Now we're integrated and working from a clean data-set for all CRM functionality.
Samless, efficient & gets the job done.

Adrian Brown, Ballpark
Working in sales and being a bit of a tech-phobe made the thought of migrating to a new CRM very daunting. Will removed every piece of anxiety we may have had and integrated two key tools incredibly quickly, resulting in no impact to our day-to-day, and ensuring our valuable time was respected. Clear expert in this space where no ask was too much. Personable and very easy to work with, going above and beyond to support any niche request we'd throw at him. Would trust Will again.

We worked with Will to reinvigorate business development for our creative agency, with a particular focus on targeted sales messaging and pipeline management. Will helped us to find the value in our existing contact data and set up Attio to enable improved sales performance. He was a pleasure to work with and comes highly recommended from us!

Being new to the platform I needed assistance with migrating data to Attio while maintaining communication between 2 platforms. Will was instrumental in creating a plan based on what we needed. With this plan we worked together on various pieces and he also created workflows and, using other programs created the 2 way communication we needed. He showed me how to do this and I may duplicate and not need to create from scratch. We were able to set up Attio using all its capabilities.

Sideways helped us bring in Attio to deal with a significant increase in new enquiries. Will helped to replicate our setup from Zoho, migrate existing data, design new workflows and create integrations that pull data from various sources. We're now in a far better position to scale the business.
