Bu.mp – Mobile Sync

Bump: Mobile SyncBu.mp is a new mobile app that uses web technologies and location services in order to facilitate a revolutionary new way of sharing contact details, common contacts and photos between two nearby mobile devices that “bump” into each other.

The mobile app can be installed on iPhone and Android phones. It uses the phone’s sensors to literally “feel” the bump, and it sends that info via the web to the Bu.mp servers. A matching algorithm listens to bumps from phones around the world and pairs up the phones that felt the same bump. In order to limit accidental bump matches, the app requires location services to be activated on both phones, to limit the matching possibilities.

The app website only has 4 letters, separated by a dot in the middle, bu.mp, which certainly helps in making it easy to remember for everyone. According to the Compete stats, the site had 5’000 monthly unique visitors on average in the last few months.

The company, Bump Technologies, was funded in 2008 by Jake Mint, David Lieb and Andy Huibers. It is based in Mountain View, California and funded by Y Combinator, Sequoia Capital, Andreessen Horowitz and other angel investors.

Flickr – Host Your Images Online

FlickrFlickr is an image-hosting site that allows its users to upload and share with their friends and the world at large their favorite photo albums.

Flickr offers two types of accounts, Free and Pro. The free accounts don’t allow the option of downloading the image files, and only the most 200 recent photos are indexed in the account’s homepage. Free accounts are also subject to deletion after a period of 90 days of inactivity. Once upgraded to the Pro plan, users gain the ability to download the files for previously uploaded images, and they are no longer subject to the inactivity deletion rules.

Flickr was initially launched in February 2004 by Stewart Butterfield with his then-wife Caterina Fake. The site was acquired by Yahoo! in March 2005 (the reported acquisition cost was $35 million). On 16 June 2007, Yahoo! Photos issued a press release stating that its service would end on September 2007, in order to focus the company’s efforts on Flickr.

In 2008, Stewart and Caterina resigned their Yahoo jobs. At the end of November 2010, Yahoo was on the verge of a major layoff affecting 10%-20% of its workforce and Flickr was specifically named as a target for these layoffs. In August 2011 Flickr reported that it continues to see strong adoption for the service; it stated that the site hosts more than 6 billion images and that this number continues to grow steadily.
