Aurora Feint started out as a puzzle game developer for the iPhone platform but has since evolved into the maker of a comprehensive social gaming platform dubbed OpenFeint that continues to attract independent iPhone game developers to join its rapidly growing community . Today, the startup is launching the private beta of OpenFeint X, which offers indie developers the ability to create Zynga-like free-to-play games including microtransactions and virtual goods. With the success of Zynga and PlayFish on Facebook, Aurora Feint wants to help create more of these types of free-to-play games on the iPhone. Launched with Japanese investment partner and mobile gaming company DeNa Group, OpenFeint X will be rolled out to the general public in phases over the next few months. With the international investment in the project, we can assume that OpenFeint X is designed to develop games that appeal to global markets as well. Using the new platform, developers can create games with a chat wall where players can interact with each other, a newsfeed showing recent in-game activity, and game nudges. And OpenFeint X’s premium services allows developers to use a cloud-based infrastructure to build and run a full virtual goods store, access detailed analytics, and include game-specific currency wallet. The existing OpenFeint platform is quite popular amongst developers and already powers social gaming services for 12 million users and is growing at a monthly pace of 25 percent. The strategy of trying to develop Facebook-like free-to-play games through Open Feint isn’t surprising. Peter Relan, executive chairman of Aurora Feint, also happens to be the executive chairman of CrowdStar, a social game developer on Facebook, which makes develops Happy Aquarium, Happy Island and Happy Pets.

Kiva is p2p-lending site that facilitates loans between lenders in wealthy countries and entrepreneurs in developing countries. Now a new startup aims to bring a simialr model to startups in the developed world but with an investment focus. The idea here is to fix the current inefficiencies of private seed funding for web and mobile companies, especially in markets outside of the hothouse that is Silicon Valley (i.e. Europe and Asia). Grow VC is a new community funding model for technology startups. Here’s how it works: Grow VC will pool 75 per cent of membership fees into a community fund that gets invested back into ‘promising startups’ which are members of the platform. The fund is managed by Grow VC but all the investment decisions are left to members who determine how to invest their portion of the fund into other startup companies that they feel have the most potential. The most successful decision makers get financially rewarded when the community fund begins earning a return on investment. So, if you promote the best companies you make moola. Joining Grow VC, and the basic features such as building a person profile, are free. Premium features come with subscriptions ranging from $20 to $140 per month, depending on how much money the startup company is seeking or how much the investor is looking to invest. For unlimited service investments, the monthly subscription fee is $90 per month. The fund is aimed at startups that need $10,000 to $1 million USD.

Yammer , the San Francisco startup that offers a solid enterprise-grade microsharing and realtime communications service, is expanding its executive team after successfully closing a Series B funding round to the tune of $10 million earlier this month. The company made one internal promotion, appointing co-founder and VP of Technology Adam Pisoni to CTO. In addition, Yammer recruited David Satterwhite to lead its sales efforts, while Steve Apfelberg was brought in as VP of Marketing. Before working at Yammer, Adam Pisoni served in senior engineering roles at Geni and Shopzilla and co-founded and was CTO at Cnation. The company says Pisoni played an instrumental role in building Yammer’s communication platform from the ground up, adding that is now in use by over 60,000 companies and organizations (including TechCrunch). David Satterwhite, who recently joined as executive vice president of sales, began his career in sales at Oracle and then held multiple roles at Clarify. Satterwhite went on to lead worldwide sales at NightFire Software, @Road, and newScale, before making the jump to Yammer earlier this year. Finally, Steve Apfelberg served as the senior vice president of marketing and business development at Callidus Software before joining Yammer as VP of Marketing in October 2009. Prior to Callidus, he held senior roles at Siebel, Remedy, and Oracle. He’ll be working with Jon Grall , who recently joined Yammer as Senior Manager of Product Marketing after a brief stint as Product Lead at Dropbox. Yammer has seen solid growth since winning the 2008 edition of our TechCrunch50 Conference, and with close to $15 million in venture capital and a slew seasoned SaaS executives at the helm, the startup is well-positioned to sign up more customers and grow to profitability in the next year or two. We’ll be monitoring them closely along the way, and not just when they go down . CrunchBase Information Yammer Information provided by CrunchBase

Ah, the college library photo. Look through any school’s brochure, and there’s a good chance you’ll see photos of an ethnically diverse group of students pouring over the same math problem together, all of of them inexplicably grinning ear to ear. It’s a nice thought, but unfortunately it doesn’t happen all that often — instead, many students wind up studying alone, and when they can’t figure something out, they’re out of luck. Now, entrepreneur Pooja Nath is looking to turn this kind of group learning into a reality for more students (at least online) with her startup Piazzza . Piazzza is still in a private beta and has quite a ways to go before public launch, but we got a sneak peek at its current progress. The site is designed to help classmates share their questions and answers in a format that’s a bit like a mixture between a wiki and a forum. Each class gets its own hub for Q&A, and students can bookmark any questions if they’re also eager to find out the answer. Multiple students can contribute to each answer in a wiki style but there’s a version history that shows what each student wrote. Students are free to independently create Piazzza hubs for their classes, but I suspect the site will get more traction if it gets professors to sign up. When a professor joins Piazzza, their answers are separated from the students’ to make them easier to find. And professors can also look to see which questions have been bookmarked by the most students to gauge which topics they should explain better in class. So far Piazzza has opened to around 600 students across 9 classes, and plans to open to around 50 classes in a few months. Initial response from professors has been quite positive . And I liked what I saw from the service, though I think it needs to build out some technology that would make it harder to reproduce. I also think that Piazzza will really need to get a large number of professors using the service, which will be difficult. Nath says that Piazzza was inspired by her own personal experience. As a student studying computer science at India’s prestigious IIT Kanpur, she found herself to be one of only three female students in a class of fifty. She says she was a bit shy and never really got to know many of her classmates, so when it came time to study, she didn’t get to bounce ideas off her peers. After working at Oracle, Kosmix, and Facebook, she’s now a Stanford MBA student. CrunchBase Information Piazzza Information provided by CrunchBase

Last fall, TechCrunch50 startup ClientShow presented its innovative application to help creative, advertising and marketing professionals show, pitch, share and sell their work to clients more effectively through real-time collaboration and communication. Similar to a WebEx for creative professionals, ClientShow allows users to essentially create a “virtual agency” to collaborate and share ideas with clients. This week, the startup is debuting its platform in private beta. We have 1000 invites for Techcrunch readers here. The application, which is built on Adobe Air, includes a dashboard which lets the agency view client lists, projects and pitch sessions at a single glance. The dashboard acts as an organizational launching pad, where you can see attached notes and images about upcoming pitches and a schedule of sessions. The second feature is a “work” section which actually lets you set up and prepare for the sessions. You can drag and drop your files into the application, where you can view the projects. To engage in a virtual “pitch,”clients are given a link that lets them view the session in their browser. While the users who are pitching the idea are using an Adobe Air application, the client will see the actual pitch within their browser. Here’s where ClientShow brings in the collaboration angle: as you are pitching an idea, decision makers on a client team can approve (or dismiss) different ideas and files and give feedback automatically by adding notes and comments to the pitch that are updated in realtime. After a pitch has ended, users will want to look back on clients’ comments and feedback, which is where the fourth part of ClientShow’s software comes in. The “vault” captures and stores all interactive feedback from sessions. You can also see session reports”in the vault that shows you every file that was documented in the presentation in the order they were presented. The entire application is free, but ClientShow will be monetizing by offering a paid version that includes additional premium features. The startup has raised $750,000 in funding so far from undisclosed angel investors and will be launching the application to the public in the next two months. Of course, my one complaint about the application is that it is built off of Adobe Air which is buggy and has other problematic issues. However, the realtime collaboration functionality of the application is compelling. The ability to create threaded discussions around a pitch and collaborate easily is sure to be useful to the creative industries.
