The week in tech startups, August 19th 2011…

By Brian Kovalesky, StartUp Beat Editor

It was a week that saw harrowing ups-and-downs in global markets, and talk of economic doom-and-gloom. But it was generally business-as-usual for technology startups. The theme of the week was acquisitions, led by Google’s Motorola buy…and then HP’s massive $10 billion acquisition of software firm Autonomy. But some smaller names got into the act as well, proving that (at least some) nimble tech startups may have a brighter outlook on the economy than Wall St. and the punditry.

Perhaps the most notable buy was Chegg’s acquisition of homework help site Student of Fortune (which gets this month’s “Best Name” award). But startups Evernote and HubSpot also opened up their wallets to bolster their product lines. Finally, daily deals startups continued to make news in their quest to compete with Groupon with deals site BuyWithMe’s acquisition of Scoop St. (what’s with the names of these daily deals sites?). In funding news this week, highlights included Chinese luxury brands shopping site Xiu.com’s $100 million round, and cloud-based video licensing platform Thought Equity Motion’s $25 million..it’s a tough sector to play in, but having an additional $25 million helps.
