"I’ve been very impressed with Gus and his team.
We work in a fast-paced, iterative environment where precision to detail and speed-to-market is key.
Gus and his team at Atom 6 Design worked on the UX of our B2B software and have continued to knock it out of the park. He is a great designer with an excellent eye for detail. When the guy sleeps, is an unknown; the timezone was a great advantage, as it allows us to work at our office hours with no problem at all.I am sure you'll be happy with his get-it-done attitude, optimistic view of the world, and friendly interactions.
There is no doubt we’ll be working with them again."

“Gus and his team created a visual for our chatbot Betty, which was a really difficult task. We didn’t want a classic robot design and it had to unite our CI with connotations of AI and technology.
