It’s been a big week for many alumni startups who’ve presented at Under the Radar. With two acquisitions and some serious funding rounds announced, 2010 already looks up for tech startups hoping to raise dollars and woo buyers as the economy attempts to sturdy itself this year.

Today, two UTR alumni have joined forces, with Jive Software (who presented in 2007 while they were still fresh on the scene) acquiring fellow UTR presenter Filtrbox.

From ReadWriteWeb:

Jive sought a social media monitoring company to bring into its Social Business Software (SBS) platform. The goal is to extend the social footprint of the Jive platform. Jive sees the market becoming far more oriented around conversations on social networks such as Twitter and Facebook. These conversations affect everything from product development to sales strategies. Monitoring is critical to following and capitalizing on the conversation flow.

Congratulations to both groups for joining forces!
