Karthik and Dart Innovations has done an excellent job working on our projects for the past 12 months. They are extremely responsive and do excellent work! If they don’t know how to do something, they will research it extensively and do their best to accommodate you! Also, they work very late at night so they can communicate with their customers in the US. This is extremely helpful since you can chat with them live and not have to wait hours or days for a response. Thank you guys for all you’ve done for us!
