Now what

8x8 is becoming a global voice over internet protocol (VoIP) service provider with recently opened data centers in Amsterdam, Singapore, and Brazil. The company's unique blend of digital voice and video communications products is gaining traction around the world, creating a new runway for international growth. Overseas sales still only account for 12% of total sales, up from 10% in the year-ago period.

Average sales per corporate customer are also on the upswing, increasing 14% year over year in the second quarter. 8X8 is not necessarily an investment for every portfolio given its near-breakeven bottom line and sky-high valuation ratios, but there's still plenty to love about this next-generation communications platform.
