About Sideways CRM

Get Attio built around how your business makes money, not around a tech stack.

I'm Will Sawney. If you want Attio set up to fit how you actually want to operate - let's talk. Together we can create your ideal commercial setup.

I work with founders and leadership teams who are done with systems that slow them down. My job is simple: understand how you operate, build something that fits, and get out of the way so you can focus on what you're actually good at.

No juniors. No process for the sake of process. No buzzwords. Just a well-built setup your team will actually use - and a commercial operation that runs the way it should.

35+ implementations across VCs, M&A advisors, brokers, consulting firms, B2B SaaS and high-growth service businesses.

✨ How it works

1. Understand - I meet your team, get under the skin of the business, and map exactly what you need.

2. Design - I build a clear plan before work begins.

3. Build - I implement everything, integrated and ready to use.

🗲 My Studio Setups library shows real examples of how I solve specific commercial challenges - from deal flow automation to LP reporting to multi-partner pipeline management.

Ben Brierley, Co-gency Corporate Finance
Working with Will was a great experience from start to finish. He helped us build an AI CRM system in Attio that integrates with our other systems exactly as we wanted. No question was ever too much trouble, and he was always willing to explain things and find solutions. He’s trustworthy, highly knowledgeable, and genuinely focused on helping his clients succeed. I know I can count on him for any future updates or improvements.

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!

Vikram Rao, Sable Bio
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.
