Over 100 startups applied to present their companies at the TechCrunch-sponsored Connected Innovators program at the Supernova conference last week. Twelve were selected and had a chance to launch their new products to an audience of hundreds.

I drafted some real-time notes of the products demo’d and launched at event at CrunchNotes, and my more complete notes are below.

Attensa	Ether	lifeio
Netvibes	PostApp	PROTOMOBL
Sharpcast	SoonR	StumbleUpon
Vpod.tv	Webaroo	ZiXXo

Sharpcast

Palo Alto-based Sharpcast (TechCrunch posts here) has developed a platform to sync application data across your computers and mobile devices. Their first showcase application is Sharpcast Photos, which not only pushes photos from one device/computer to others, it also keeps them synced. Make a change on one and it pushes the changes to the other copies as well. There are lots of new applicaitions coming as well (documents, calendar, contacts). The company, which has raised $16.5 million in capital, will be application-agnostic so you don’t have to switch to using new software. Windows only today, Mac coming soon.

Webaroo

Webaroo, headquartered in Santa Clara is a new service that launched in April that allows PC users (no Mac support yet) users to access cached web content when they are offline. Webaroo offers pre-selected content, called “web packs”, and users can also cache whatever websites they would like to have access to. For more, see the TechCrunch Webaroo review here.

PostApp

PostApp is a new company that allows users to pull web services directly into their blog or other website without having the technical skills to use the API supplied by the service provider. With the explosion of widgets, PostApp may be the right application at the right time. They also secured $1.5 million in funding from Hummer Winblad. See the full profile here.

Vpod.tv

Vpod.tv was one of my favorite companies presenting at a conference in Spain last month. It is a video sharing site, similar to YouTube, but that focuses on transcoding to most video devices (ipod, PSP, etc.) and allowing users to download video to those devices. They also have an innovative approach to monetization. See the full TechCrunch post here, which also discusses their $5.1 million funding.

Ether

Ether officially launched at Supernova. They’ve created an “ebay for services” that allows people who wish to sell their time on the phone to do so. Place an Ether logo on your site – when someone clicks on it they can set up a time to speak with you according to the terms you’ve set (price, time of call, etc.). When your phone rings, there is a person on the other end who has already given their credit card information and is looking for your advice. Ether went into beta in March, and we covered the official launch here.

Lifeio

Bruce Spector from attap gave the Supernova audience a very early look at Lifeio, “the new life organizer”. Lifeio will combine instant messaging, email, calendaring, contacts, to-do lists, etc in a multipage Ajax site (from what I saw it looks like Lifeio is competing with Goowy, Netvibes, Pageflakes, etc.). Lifeio is also opensourcing the platform framework, called jitsu. Look for more details as the September launch date approaches, and sign up for the beta on the Lifeio homepage.

Other attap companies include Riffs, Buzzvote and personal DNA.

GearON

GearON, a mobile service launching this month from ProtoMobl, centers on your phone’s contact list and creates a social network around it to share photos, music, events and venue information. See the flash demo of GearON here to get a better idea of what it’s all about. Their launch will be covered on MobileCrunch as well as here at TechCrunch.

Soonr

Soonr is a new mobile platform that we’ve previously covered at TechCrunch. One of the most useful applications they’ve launched so far is the ability to use Skype on a normal cell phone (all you pay for are the Skype-out charges from Skype to your own cell, and you can then use Skype to call anyone on your Skype list). The Mac version of Soonr was announced at Supernova.

Zixxo

There are a few ways to look at Zixxo. For users they will deliver highly targeted local and national coupons to you based on whatever personal and demographic information you choose to share with them. For businesses, they are a very cost-effective way of reaching consumers who actually want to receive these coupons. For third parties there is a revenue share opportunity for bringing users and/or businesses to the network. Zixxo is still very young, but the core idea is strong. Look for a potential quick acquisition of this company if they start to get traction.

Attensa

Craig Barnes, the CEO of Attensa, talked about how his suite of RSS reader applications (mobile, outlook, online) analyze user behaviors to recommend specific content and help people deal with information overload. They’ve also just released a new version of Attensa for outlook. TechCrunch posts on Attensa are here.

Netvibes

Founder and Co-CEO Tariq Krim gave the audience an overview of London and Paris-based Netvibes, the Ajax home page that has seen tremendous growth and now has millions of passionate users. Netvibes now has an active community of independent developers creating modules for the site. Netvibes is on a roll. TechCrunch posts are here.

StumbleUpon

StumbleUpon is a social browsing application. Users download a browser toolbar and can find popular sites in different categories, vote on sites, etc. Stumbleupon has nearly 1 million registered users in 139 countries, who “stumble” 2.2 million sites er day. Advertisers can get their ads in front of a targeted audience for 5 cents an impression. I use this service.

Stealth start-up PostApp announced at Thursday’s SuperNova Connected Innovators session the launch tomorrow of WidgetBox, its new beta marketplace for managed web based widgets, and $1.5 million in funding from Hummer Winblad.

If you like widgets, there’s about to be a whole lot more of them available for use in your blog or profile page. If you’d like to develop widgets and have some one else deal with the details, this could be for you. If you’re unfamiliar with widgets, see the “community powered search” box on the right side of TechCrunch – that’s a widget. Videos, slide shows, music players and news tickers that can be dropped into web pages are common types of widgets.

PostApp is headed and B2B veterans Ed Anuff, Giles Goodwin and Dean Moses. The company debuted its first offering, an eBay widget, in partnership with Typepad at the end of March.

PostApp will manage the process of turning web services into widgets that bloggers, social network users and others can insert into their pages. Outside developers will create web services, submit them to PostApp for transforming into widgets and content publishers like bloggers, auction sellers and social network users will select the widgets they want from the WidgetBox marketplace. The service will also manage the money for widgets that involve financial transactions like affiliate links or subscription, though developers will have first say in determining the business rules of their projects. PostApp will act as a master affiliate or subscription center, as appropriate.

As the number of photo, video, eCommerce and calendar widgets available online proliferates I can’t help but think that a central place for lots of widgets sounds like a good idea. I also hope that this will make it easier for developers to create other kinds of widgets, as the choices out there can feel pretty stale.

One of the first highlighted widgets will use the Yahoo images API to insert contextually relevant images into any website. RSS will be the basis of many, but not all of the widgets. If you love RSS as much as I do, you can probably imagine almost any information being delivered by feed and thus displayed in a widget. If an interesting variety of feeds are widgetized and then mixed with intermittent contextual advertising – then everybody wins. I’ll eagerly await the widgets of the future.
