Today’s fundings show the continued trend to social and mobile experiences — with one entrepreneur bragging he took money he didn’t need:

ClickFox gets $18M to keep tabs on customers: Atlanta-based ClickFox monitors touch points with customers of Fortune 500 companies online, on the phone and in stores, then uses the data to improve the customer experience. Morgan Stanley Alternative Investment Partners led the funding round, which will be used in part to expand the product’s social-media capabilities.

Marketo brings in $25M for sophisticated marketing: Twitter and Zynga backer Institutional Venture Partners led the round for the developer of lead management software with more than 750 customers, including AdMob, Drop.io and EMI Music Publishing. The round is Marketo’s second this year, though CEO Phil Fernandez said he and the startup “haven’t spent a penny” of the $10M raised in April. “We have a war chest of more than $37 million now,” Fernandez wrote on his blog.

OnAir3G grabs $2M to develop social service for smartphones: The Moscow-based startup raised a first round from Russian VC Runa Capital, peHUB reports. The investment is also the first for the Runa fund, which launched in August. OnAir3G’s founder’s previous company was sold to Russian search engine Yandex in 2007. The company plans to launch its mobile application in mid-2011.

SuperSonic Imagine raises $25M more for medical imaging: The French company has now raised a total of $45M in a third round of funding to bring its ultrasound technology worldwide. The technology provides doctors with color-coded maps of tissue, offering more information about lesions than that available with traditional ultrasounds.
