4xxi Reviews
Anton Petrov
"They can look at a startup from different angles and provide insight on how to improve."
The platform has gotten good feedback for its quality. 4xxi are strict with sticking to timelines, but what’s most remarkable about them is their 24/7 availability, smooth communication, and their willingness to provide new ideas on how to do things.
Steven Emanuel
“Working with 4xxi has been one of the best commercial experiences of my business life.”
Not only did 4xxi create the exact tool that was requested, but they charged a much smaller price than U.S.-based companies. Although they are overseas, the time difference isn’t a problem, and their communication is clear.
