Are there enough positive adjectives to describe how Will has helped us? He's a responsive, knowledgeable, cost-effective expert with Attio and how it can be built, integrated, and made bespoke to our needs. 100% recommended.

We worked with Will from Sideways CRM to help us get up and running with our Attio CRM. We sort of knew what I wanted, but quickly found a needed some expert help. So we contacted Sideways. Will helped us integrate Xero so quotes and invoices were visible to the correct companies in Attio. Will ironed out a lot. We communicated via slack, he had a client portal for visibility, and we had regular calls. Would strongly recommend!
Great experience - Highly reccommend

Over the past ~year, Will has helped our organization professionalize our sales process, enabling us to run advanced reporting, conduct detailed pipeline mgmt reviews, and key in on priority opportunities. We're a scaling (rapidly) startup, & never would have had the ability to take these efforts on ourselves at even a basic level, to say nothing of the advanced capabilities he's helped us unlock. Great experience start to finish and I look forward to continuing to work together in the future!

Will set up Attio for Sable Bio and delivered exactly what I needed at this stage: a clean, reliable pipeline tracker with sensible structure behind it. He quickly understood how we sell and implemented clear Deal / Account logic, light MEDDPICC discipline, currency handling and weighted forecasting. Pragmatic, easy to work with, and strong on foundations without over-engineering.

Will / Sideways team took an incredible amount of time to understand the unique aspects of our business, what we needed, how to integrate with outside platforms, and built us systems that were highly customized to us, not just a generic template.
