Hear from the people whose products we helped level up

"Paulina and team helped us with a redesign of our website and we're really happy with the results. To be honest, we had very few revisions throughout the whole project simply because they nailed the vision from the get-go. The designer, Paula, has a great eye for layout and typography and really brought our ideas to life. Would not hesitate to recommend them or use them again in the future. Thank you!"

James Lin

President at Alpha Bidet

"Working with The Rectangles has been a really solid partnership for us at Aviator Gear. Their team has a great handle on conversion strategy and UX design, and they’ve helped us bring a fresh, more effective approach to our email creative.

What stands out most is how easy they are to collaborate with. They’ve also been incredibly flexible, which means a lot for us as a small, entrepreneurial company that sometimes has to switch gears or change direction quickly.

The Rectangles have become a trusted extension of our team, and I appreciate the balance they bring between innovation and results."

Cory Bower

President at Aviator Gear

"Everything went smoothly and efficiently, with no delays. The new designs made me revisit and improve key areas of communication for the The Organic Protein Co. 

The changes were subtle and didn’t mess with the brand, but made a real difference. A ‘no drama’ process with great results."

Daniel Whitehead

Founder of The Organic Protein Company

"We worked with The Rectangles on a full redesign for our ecommerce website. In the end, the project increased our conversion rate by about 80%. They are great people to work with, and very talented. If you’re looking for an agency to help with design or CRO,
I definitely recommend checking them out."

Zac Plansky

Founder of AT3 Tactical

"Working with The Rectangles has been one of the best decisions we’ve made for our website and brand. Their team has completely transformed the user experience on our site. Everything now feels so much more cohesive, intentional, and aligned with our story.

They helped us not only improve design and flow, but also built a custom dashboard where we can easily track analytics from all our channels in one place. It is a very helpful guide when we make decisions about what's working and what's not.

Beyond their technical skill, the team is just great to work with: creative, thoughtful, and genuinely invested in our success. They always bring fresh design ideas and perspectives that push our brand forward. We couldn’t recommend them more highly!"

Emily Ayers

Marketing Director at CapsToYou

"We think of The Rectangles as part of the KnowledgeOwl team. It’s amazing to have a whole team of people who care as much about your customers and product as you do.

The best part of The Rectangles approach to UX is the research, thought, and love that goes into their UX designs. They dive deeper into our data than we do!

Their subscriptions plans are a no-brainer. For a fraction of the cost of a single freelancer or part-time employee, you get a team of experts on hand to help with your business goals."

Marybeth Alexander

CEO of KnowledgeOwl

"We’ve really enjoyed working with The Rectangles. Their team is skilled, professional and the communication is great. I like that they take time to learn about users, company, product before starting to design anything. Also, I like that they have psychology background. This sets The Rectangles apart from other UX design agencies."

Mike Iwasiow

CEO of Bookedin
