Overall, I am very satisfied with the work done by Grossum As one of the measuring points for me was the fact that I have received many compliments on the end product Thanks, Grossum! We're very happy that we chose Grossum to develop our app, Authenpic We've had a good experience with them since day one They understood our plans and concept very quickly, and we had an open dialog with them throughout the whole process They delivered within the set timeframe, and they offered guidance and help through the process of launching our app We will definitely work with them again when we want to expand the features of our app

Founder and Managing director I had a pleasure working with Mariia and Anastasiya They were very responsive, always there when needed I wish Grossum had developers who understood the technologies we are using to develop our products We would worked together longer

Thank you for your work and creativity We really liked the results of our cooperation and we are happy with the product we got in the end

Great work Anastasiya! Great support Mariia! The cooperation has been successful and we're happy with the result Our only complaint - we have never heard Mariia sing! Working with Grossum definitively exceeded my expectations! We are comfortable now to try more complex apps Very responsive, smart, and get things pretty fast The only complaint I have could be more interaction with QA guys There were bugs in the app we found that could have been easily caught if I could setup tests premises with the QA guys! The competence of the developers in Grossum is excellent I am very satisfied with their responsiveness and meeting deadlines I would recommend Grossum to any person that has a specific web-based project that requires specific attention due to unresolved difficulties Congratulations for your work and efficiency

The provider is good and a pleasure to work with I would work with them in the future given the fact that they have good work ethics and professionalism We are very happy about our choice Fast and straightforward Great Symfony developers Dedicated people

CEO, Prof of Dermatology I have enjoyed working with Grossum during the development of our project called Biudee (iOS and Android native apps designed for keeping one's skin beautiful and healthy) One of the things I have found especially helpful was easy and close daily communication that we had with both the PM as well as the developers
