visto.jpgThe mobile email company, Visto, has become one of the most controversial companies in Silicon Valley.

The Redwood City company has reportedly raised another $35 million in venture backing led by new investor Altitude Capital Partners, adding to the whopping $350 million the company has already raised. It is in the red, after ten years, and hasn’t announced a major customer in several months. Its penchant to file lawsuits is also worrying, and we’ve said before that is a reason why bias has crept into our reporting about this company.

Valley gossip site, Valleywag, says the company is on the rocks, but has no facts to back it up. PE Hub’s Dan Primack says the $35 million in cash, raised in December, would seem to contradict that, however there is no one on the record explaining the terms of that cash — and it is somewhat odd it wasn’t announced. Moreover, the company has a large cash burn rate, as Dan points out, caused by service contracts it pledged to.

Now we’re hearing its investors are spreading word that a 2007 acquisition is better than 50-50 odds. Yet we’re skeptical too, given that the company had said it planned to go public last year — and nothing happened (indeed, read that previous link for notes about the company’s questionable marketing). Indeed, with its huge cash burn, it may have to be sold.

Has this company hit the wall? We’ve contacted the company, and will report back if we hear anything.
