I am an Engineer by profession. I have visited several companies in Gujarat to make IoT products with End-to-End development. Most of the companies provide, but they lack in software as a Service, which is quite hectic to outsource to a different company for SAAS. Once, I got a referral from one of my friends and met the owner of LA hagora. They literally meant to provide all the End-to-End development from PAAS to SAAS that too in the best budget. One of the best company if you are looking for an IoT solution.
