What Our Clients Say

  • “All members of the team agree that 3Si2 has been a good vendor to do business with and we would do business with you again. I personally think you're one of the best vendors I've worked with in my 27 years in the software engineering industry. I appreciate the high level of integrity you do business with. I encourage you to use me as a reference any time you like.”

    Joyce Thomas ICANN / Technical Project Manager
  • “I want to recommend 3Si2 on the excellent job they did on our player evaluation system. After meticulously interviewing many developers to help us with our project, we decided upon 3Si2 due to their professionalism, technical savvy, and fair pricing. We couldn't be happier with the decision. Since day one, their response time to our requests/needs was excellent and they did a great job of trying to ensure our complete satisfaction. It has truly been a pleasure working with these guys and we will continue to look to them for any future software development needs. We will also be using them for maintenance and support. I'd highly recommend 3Si2 to anyone and I look forward to our continued relationship with them.”

  • “3Si2 has taken our dream to reality. Developing our own software had turned into a nightmare until we connected with the team at 3Si2; with their skills, direction, support, and a responsiveness we had never known existed in this field, we achieved levels of success in time frames we had not believed were attainable. We sincerely recommend their services, they will not disappoint you!”
