They are true experts in mobile app development!The most important thing to us when working with any company is that they take responsibility for the work they do and show a high level of expertise in their field.

We cooperate with Ptolemay for the last couple of years in terms of outstaffing demands. As we have already worked on more than 6 big projects, they have proven themselves as a reliable partner that provide high quality developers. Despite the difficulty of the position we need, they are always ready to involve their team to help us cover the demand. Even though any cooperation tend to have its own issues and misunderstanding, the Ptolemays’ team has always been open for resolving problems and finding compromise

Web Design Review from Venkatesh Prabhu Janardhanan
Choosing Tentackles was driven by their stellar reputation and expert design team, who refined our vision and provided exceptional service from the start. We needed someone to create three websites for Consulting, Textiles, and Agronomy. And Tentackles did it by conducting thorough research and ensuring seamless design and implementation. Their collaborative team (esp Mr Kishan's expert-perspectives and suggestions around design) met our strategic goals, and the upgraded UX/UI design had a positive impact. Their flexible, knowledgeable, and creative approach exceeded expectations, though expanding their services could further benefit clients.
