03 · Twilio Studio
Nocode in communications
Twilio Studio was an early bet that workflow builders could replace developer effort for a large class of communication apps. A drag and drop tool for configuring actions on phone numbers and other communication resources.
Studio: visual workflows that fit surprisingly well with developers
Twilio were one of the first to introduce no-code into CPaaS. While Twilio maintains the use of the word Studio for this service, most other vendors went for Flow. They were immediately followed by other vendors.
04 · Beyond communications
Twilio adjacencies
Besides the main building blocks of CPaaS, Twilio has shifted towards adjacencies to increase its revenue. Mostly through high profile acquisitions. The pattern matters because every CPaaS vendor eventually faces this question: stay focused, or absorb adjacent workflows?
