From Plivo Open Source to Plivo Cloud

We always believed that everyone should have access to building high quality voice and SMS apps at an affordable cost.

Plivo's story goes back to 2011, when the founders, Mike and Venky, accidentally exchanged messages on Github. At the time, they were both independently seeking a robust communications platform to develop and integrate Voice and SMS capabilities into their web apps.

They couldn't find any platforms that allowed the flexibility to write applications using HTTP APIs without having to pay high carrier markup fees, so they decided to roll out their own solution: Plivo Open Source, which soon turned into a full-featured cloud platform called Plivo Cloud.
