I'm Voxeo's CEO.

First - Danielle I have the utmost respect for you and the marketing momentum you've been able to build around Twilio. However, saying the "quote is completely fabricated" is itself is fabricated ;) It's not a quote - it's a reference to something you said at ITExpo west this year. Diggz wasn't there, but he (and I) were told by multiple people that you said it.

Voxeo is an extremely open and honest company. I mean extremely. I seriously doubt any single Voxeon would make this up, never-mind multiple Voxeons. It's personally important to me to resolve this because I feel the honor and honesty of Voxeo is being challenged when you say it's "completely fabricated". Are you claiming you said nothing at all like that?

Second, wether you now acknowledge saying it or not… to be frank, in my (and many other web-powered telephony industry vets) opinion it happens to be pretty darn true. Twilio has done a great job focusing on simplicity. Twilio is many great things - but Twilio is not innovative. I'm not trying to be a competitor or a jerk when I say that… I honestly have not seen a single technology innovation delivered by Twlio. If you disagree, please suggest a few and so I and others who have been doing this for ten years can openly and fairly respond.

I'll give you some examples of what I mean - compared to Voxeo. But I want to make it clear that this is not all about Voxeo. You could also make comparisons to TelMe, Bevocal, Telera, Motorola and several others who were around ten years ago. Voxeo is far from being the only company that invented and innovated the web telephony industry ten years ago:

1. Voxeo created and patented most of the technology and concepts Twilio uses today . in 2000, as shown here:

2. Like Voxeo, Twilio makes it easy for any web developer to create telephony applications, with a focus on lower cost and ease of use. Voxeo has done that for ten years, as shown from the archived Voxeo developer web site on August 19, 2000:

Sound like a familiar message?

3. Their are slides in Twilio's 2008-2009 investor presentation which are nearly an exact duplicate of Voxeo's 1999-2000 investor presentation. To be clear, I don't know if Twilio's founders saw our presentation but the business plan concepts are so similar that slides were nearly exactly duplicated. Down to the words and diagrams used.

4. Twilio leveraged "super angels" to help build marketing momentum. Although the term didn't exist back then, Voxeo's angel investors in 2000 included Eric Schmidt (now CEO of Google), Dale Fuller (then CEO of Borland), and David Orfao (then CEO of Allaire) ... they helped us build significant marketing momentum.

5. This is the first Voxeo example app in our docs, circa 2000:

<callxml>
<text>Hello World</text>
</callxml>

This is the first Twilio example in your docs, ten years later:

<Response>
<Say>Hello Monkey</say>
</Response>

All marketing BS and propaganda aside: Voxeo and Tropo.com are just way ahead of Twilio when it comes to innovation and features. Everything Twilio has today Voxeo had ten years ago. And Voxeo/Tropo have many features Twilio doesn't: voice recognition, open SIP access, Skype integration, universal API for voice / SMS / IM / Twitter / etc, open source web client access (phono.com), direct Ruby/PHP/Phython/Groovy script language support (no need to force everything into XML and back to get things done)… there is no way Twilio could keep up match Voxeo / Tropo innovation and features, because Twilio is ten years behind from the get-go. And Voxeo is investing more in new innovation and features today than ever.

I and the rest of Voxeo have always tipped our hats to Twilio when it comes to your marketing, modern web developer outreach, refocusing on simplicity, pricing models, etc. Seriously, hats off.

However, the singular thing that bugs me (and other industry vets) about Twilio is how Twilio pretends they invented all these features and is a really innovative company. I thought your comments and "tip of the hat" to Voxeo and Tropo on innovative features at ITExpo west was the first time Twilio has publicly been a bit honest about this. I'm honestly disappointed to see you may be returning to Twilio the party line. I hope that's not the case.
