OrderMapper, a Seattle startup which helps pizza shops process orders from customers' mobile devices, has been selected by Dave McClure's 500 Startups as one of the first recipients of the Twilio Fund investment. As part of the deal, 500 Startups has agreed to invest $10,000 in OrderMapper for a one percent stake. The money is provided to those startups which are building on top of the Twilio voice communications platform, a San Francisco startup created by former Amazon.com employee Jeff Lawson.

“This is fantastic validation for us – our vision is to become the de facto mobile ordering platform and investment from Twilio and Dave McClure is a major vote of confidence in our business," said OrderMapper founder Jim Bricker, a former systems analyst at Microsoft and Avanade.

Obviously, $10,000 is not much capital. But Bricker is hopeful that it leads to a future round of funding. Having a well known angel investor like McClure backing OrderMapper could assist in bringing in more capital.

As we've written in the past, OrderMapper allows iPhone, iPad, Windows Phone 7 and Android phone users to submit their pizza order to the local pizza shop and then have it delivered directly to the customer's doorstep.

Bricker tells TechFlash that the business is doing very well, with the company's best pizza shop already processing more than 1,000 orders. He also said the company just released a new app for the Seattle pizza chain Zeek's.

In a fun twist, the company has begun Tweeting every order that comes in via the mobile app so you can see that Bryan from LA just ordered from Kiss Pizza and Kim from Pittsburgh recently ordered from Papa John's.

Other startups selected for the inaugural Twilio Fund are Voicendo and Textaurant. 500 Startups also announced its advisory board for the Twilio Fund, which includes TeachStreet founder Dave Schappell and Programmable Web creator John Musser.
