In an era where VoIP companies like 8x8 and Vonage are in the public markets, as is MagicJack, you don't normally see that many others throw their hat into the public market that often in the USA. But that's not stopping RingCentral from seeking an IPO of $100,000,0000 dollars, as their S-1 hit the SEC this week.
If they think they're worth this much, I have to think that Twilio is likely going to IPO for a much higher amount. The reason? Marketing expense for one, and infrastructure number two. Twilio can scale much leaner, and since they work with developers they don't have layers of marketing expense that RingCentral does. While I have not read the S-1, it certainly means that the bankers are thinking with the success of late that 8x8 is having that there is money in the market for RingCentral to take.
Time will tell.
