Our Happy Clients

  • James Tjan James Tjan Product Manager at Polaroid case study For us working with EL Passion means to have a committed partner who is constantly proving to deliver a great mobile experience for the global market. We have a very open and honest working relationship, with trust, respect, commitment and fun being the core ingredients. We try to operate as one team and not as vendor/client. To me their focus on motivated and passionate people adds the human element too often missing in the tech industry.
