Om Malik has a post this morning on a Financial Times report that Vonage's two lead underwriters - UBS and Deutsche Bank - have been secretly telling the company a better option may be a “parallel process” - which means they would pursue an IPO and the sale of Vonage at the same time. Doesn't exactly give you confidence in the IPO, does it? Given the speculation about the IPO, it was puzzling to hear Charles Lax, managing director with GrandBanks Capital, talk about Vonage having a $10-billion valuation based on what eBay paid for Skype. The crazy part is that no one challenged him during two VOIP/VC sessions on Fall VON. How Lax does the math is a mystery given the talk is Vonage will have a valuation of $1-billion to $1.5-billion. A $10-billion is near-impossible unless Vonage sells a 6% stake for $600-million. Maybe Lax was trying to spice up his sessions but he either knows something or he should know better. I continue to get the feeling Vonage has lost its buzz and that the timeframe for it to do an IPO is shrinking as the U.S. cablecos become aggressive about telephony and make bigger strides in terms of attracting customers.
