In August, VentureBeat reported Ron Conway’s investment strategy in the real-time web.

After success like Google, future success like Facebook, the famous angel investor is now focusing only on real-time (and is an early investor in Twitter !)

Here is a list of companies that we’ll cover in this site, but you can start having a look:

A whole range of companies have sprung up to offer ways to tweet videos and pictures real time by using Twitter’s applications programming interface, or API, which is the glue between the platform and applications. Conway’s team has made more investments in this area than anyone else.  Investments that have a strong real-time component include Twitter, Rupture (which was acquired by Electronic Arts), HeadMix, Docverse, Kyte.tv, Scoopler, Topsy, Bit.ly, CoTweet, Fliggo, Factery, TweetDeck, and Twitvid.

He also has a bunch of other investments in Web companies where real-time technology could affect the business model, including crowd-sourcing comapnies like Digg, Hunch, ExperienceProject, Instructables, Pixazza, PBWiki, UserVoice, Wikia, iMob, Aardvark, Fotonaut, xobni and Seesmic.

Since we’re talking about a “portfolio strategy,” it’s worth pointing out the real-time companies Conway hasn’t invested in. The include Chartbeat, FriendFeed, justin.tv, uStream, Gnip, TwitPic, Yammer, OneRiot, Collecta, CrowdEye, TweteMeme, Almost.at, Twazzup and Foursquare.

Conway said that big companies Google, Facebook Microsoft, AOL and Yahoo will go after real-time aggressively. “You can’t ignore this space. I’m sure every one of these companies has a task force deployed,” he said.

He said the real-time oriented companies in his portfolio that have gained the most traction so far are Twitter, Aardvark, StumbleUpon and Caterina Fake’s new company, Hunch.

When asked why the traffic of some of his new companies, such as Topsy and Scoopler, are down considerably after their launches, Conway said part of the reason may have to do with the “hoopla around their launches.” Presumably, these companies get easy press when they launch, but struggle when the spotlight goes away especially if they are taking a destination-site approach.
