One of several startups that asks users to do poll-style votes in order to predict the future, Predictify is most notable for its partnership with the New York Times blog Freakonomics.

These sites are popping up everywhere. Most recently, we covered Xpree, which lets companies tap into the collective wisdom of their employees, and the Industry Standard, a former magazine that now asks readers to predict events like whether Yahoo will accept Microsoft’s acquisition offer.

Predictify doesn’t focus on any particular category, instead allowing any sort of question to be asked. It rewards accurate predictors with cash.

The $4.3 million funding was provided by Sierra Ventures and Sherpalo Ventures, according to Mashable, which first reported the investment. It was the Redwood City, Calif. company’s first full round.

Water cleaning, purification and desalination is becoming ever more important in the cleantech world. AqWise, like others, is touting a cheaper solution for treating water.

The Israel-based company has a biological film that it uses to filter waste water. Its Attached Growth Airlift Reactor systems can be deployed in existing treatment plants, which should help the company grow more rapidly.

The $3.6 million funding was provided by AHMSA Steel Israel Ltd, Elron Electronic Industries and Israel Cleantech Ventures.

Viva Vision, a Los Angeles, Calif. company that makes content and applications for mobile media, says it saw strong growth last year.

The firm reports revenue growth of 350 percent and subscriber growth of 130 percent, and a positive income based on EBITDA. It also grew from 15 to 23 carriers.

Medical Capital Corporation provided the $2 million funding for Viva Vision.

Tapioca Mobile is a San Diego, Calif. startup that offers to monetize multi-media messages consisting of video and images, or just plain old text SMS.

The company works with both publishers and advertisers to deliver content seeded with ads. Its executives come from Qualcomm, Nokia and OpenWave.

The $5 million funding was provided by Venrock, according to Mashable. Venrock also gave Tapioca its seed round in September of last year.

Demand Media, one of the most heavily funded companies on the internet, has boosted its lifetime total to $355 million with a new $35 million investment reported by peHUB.

While the amount would be shockingly large for almost any other company, it’s a relatively small funding for Demand; for perspective, the new investment is about half what the company payed for the social media tool provider Pluck in a deal reported earlier this month.

Demand is better known for buying large numbers of generic web sites based on the value of their names, then plastering them with advertisements. The acquisition of Pluck makes Demand look as if it might finally be moving to build out its portfolio of domains with content, perhaps partially user-generated.

The source of the newest funding was not disclosed. Demand is based in Los Angeles, Calif.

4DK Technologies, a Herndon, VA company with a “SuperConnectivity platform” that it claims can make applications on mobile phones work with each other, has raised part of a first round of funding according to TechJournal South.

The company has two different applications, called respectively SCamp and SCout. Together they draw on information provided both through applications and by the wireless provider, like GPS data, user preferences and calendars, to provide more working information to apps for decision-making.

The company’s own explanation is pretty vague, but according to one example on their website, SCamp could determine from the user’s location that he was driving and help make the decision to automatically read a received text message out loud.

The $1 million funding was provided by undisclosed investors, and is part of a total of $3 million the company is seeking, according to TechJournal.

There’s not much public on Israeli startup Cotendo, a content delivery network that Sequoia Capital recently invested in, according to Tech Confidential. The Sequoia page on the company simply states that the company offers “better performance and low operational costs.”

Despite the mystery, it seems a pretty sure bet that Cotendo is, like most newer CDN startups, aiming for better video delivery. The company’s founding team, most of whom came from an anti-virus firm called Commtouch, are also members of a Meetup group “dedicated to exploring the IP Video revolution.”

No amount was disclosed for the funding in Cotendo, although it was almost certainly the company’s first, as it appears to have been founded just a few months ago.

NanoInk, a developer of tools used to write with nanoscale “ink” for medical and security purposes, has raised a round of $12 million, according to VentureWire (subscription required).

The company appears to have raised a large amount to date. The Medill School of Journalism reported that it has taken $50 million, although that may or may not have included the current round.

NanoInk is based in the Chicago area, with an office in Campbell, Calif. It was founded in 2001.

Genesis Partners, an Israeli venture firm with ties to Silicon Valley, is raising $150 million for its fourth fund, according to Globes.

Most Genesis investments are in semiconductors and wireless technology. However, the company also funds some software firms, and was an investor in Kidaro, which was just sold to Microsoft.
