I was on the forum in October, representing Tropo, with Danielle at ITExpo West in LA moderated by Thomas Howe (http://thethomashowecompany.com/). Danielle did make the statement that Twilio could not, and would not, catch up with Tropo on features. Instead, Twilio would focus on simplicity for the broad web developer community. I respect Danielle and Twilio for making this statement at the time. As it is clear today that Twilio has a wide gap with Tropo on features. Twilio's focus on their core strength, simplicity, was smart. 37Signals has pioneered the idea of less is more with great success (albeit with an eye to staying private without VC funding). The issue is, I think Twilio has come to the realization that to compete in this space they need more depth of capability. Further, the ITExpo statement was made before Twilio received their latest round of funding. They may very well have changed strategy and now regret having made this statement. It is much easier to close the gap on simplicity than it is a wide feature gap. We are working regularly to make Tropo simpler, while maintaining its deep feature set. We are built on a platform, PRISM, that allows us to focus on the platform features rather than internals allowing us to innovate rapidly. A Twilio individual confirmed at CloudCamp QCon in San Francisco that they are working to replace Asterisk (http://asterisk.org) as their key telephony engine. Further evidence of this is that Twilio, for the first time, is working hard to hire telephony experts. Whereas previously they were proud that they did not have telephony experts in-house and would actually plug this as a benefit. It will continue to be hard for Twilio to catch-up to Tropo, given that they are having to spend time replacing the core fabric that they built their platform on. I suspect that they are most likely targeting Freeswitch (http://freeswitch.org) since Asterisk SCF (http://www.asterisk.org/asterisk/scf) is still a nascent project. I wish them luck with that, as replacing your core telephony engine is no trivial task. |
