As a startup company, we initially secured 1m in VC financing after approximately

4 months and later established several lucrative relationships with major industry

partners eventually leading to a second round of over 12m in capital financing from

a combination of those partners and other VC firms last fall. A major reason for our

ability to raise this level of capital in such a short period of time from relative

unkowns was our ability to implement and demonstrate our vision in a very short

period of time. Within 8 months of inception, we moved into our first office space

with the goal of using our own product as our only business phone system. We

achieved this goal and have relied soley on our own product to provide complete

phone service to all of our employees, most likely one of the first full scale

business based VOIP systems in full time active daily use. Company is currently at

45+ employees.
