Our team has helped many great teams improve their digital products


What our awesome clients say about us

”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 really like the way they set up the communication in Basecamp. This works 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

”The Rectangles are really The Incredibles. When I was setting up my business, I really was unaware to the importance of the transparent user experience (aka conversational UI). The Rectangles stepped in at the right time and the whole process was seamless. The end result was a very sophisticated and gives our users that experience we envisioned. I highly recommend these guys.”

— Dana Latouff, founder of Tickitto AI

”The Rectangles are analytics superheroes. They gave us a new point of view on how to organize our data. It became a no-brainer to have them execute on their plan as they were far and away the most thorough in their upfront audit as well as the most pleasant and helpful of all the partners we looked at. In a matter of days they cleaned up our analytics setup, one that had been untended for years, and set us on the path to amazing insights. It's why we are so happy to refer and advocate them for their work, and why we are always finding new ways to partner with them.”

— Suneet Bhatt, GM of Crazy Egg

Value from day 1

We all love our businesses — ours revolves around delivering value to yours

We understand goals in business. Our team embodies engagement, autonomy and trust. We care about our clients — a lot. From the first day, we aim at crushing their current goals and determining new ones. And we crush those as well. Short-term or long-term — it doesn’t matter. Neither does the headcount and industry. The first tangible results are just a matter of weeks.

Because we know what counts, we can be counted on. 100%.
