Three CEO Moves: Viximo, CloudSwitch, Paragon Lake

I don't usually track executive comings and goings here, but three interesting ones have happened recently (not all officially announced yet):

1. Rob Frasca has been replaced as CEO at virtual goods company Viximo by Dayna Grayson from North Bridge, who will serve as acting CEO. North Bridge is one of the company's investors.

2. Long-time SolidWorks CEO John McEleney is taking over as CEO at stealthy start-up CloudSwitch from founder Ellen Rubin, who is staying on in a key executive role.

3. At custom jewelry site Paragon Lake, they're bringing in former BrassRing CEO Deb Besemer as CEO, and moving founder Matt Lauzon over to COO.

Here's a recent post from Lauzon on "Hiring the Right CEO."
