Jonathan Alexander, who came to Liquidware Labs through the vmSight acquisition is no longer with the company. Despite being removed from the Liquidware Labs website over the last few weeks, Jonathan's LinkedIn profile shows that he worked at Liquidware Labs until May 2010. It's unclear why Liquidware Labs would list Jonathan on the management team for the second half of last year and it's even less clear who is heading up the engineering organization at the company since no one is listed in a similar role. Hopefully Jonathan's departure had nothing to do with the agent-based nature of Stratusphere.
Update (January 14, 2011)
It looks like Pat Clark is no longer the Chief Revenue Officer at Liquidware Labs either, although Pat's LinkedIn profile still lists him with the company. The new responsibility has been taken by J.Tyler "T. Rex" Rohrer who is definitely hungry for more revenue.
