Dropbox is a file hosting service operated by Dropbox, Inc. that offers cloud storage, file synchronization, and client software.

Dropbox, Inc. was founded in 2007 by MIT graduates Drew Houston and Arash Ferdowsi, as a Y Combinator startup company.[10]

Dropbox's basic service follows the freemium business model.[11] In 2011 Dropbox announced a new service, "Dropbox for Teams",[12] marketed to businesses and other groups.

Dropbox provides client software for Microsoft Windows, Mac OS X, Linux, Android, iOS, and BlackBerry OS, and web browsers.

History

According to Dropbox, founder Drew Houston conceived the idea after repeatedly forgetting his USB flash drive while he was a student at MIT. He says that existing services at the time "suffered problems with Internet latency, large files, bugs, or just made me think too much." He began making something for himself, but then realized that it could benefit others with the same problem.[13] Houston founded Dropbox, Inc. in 2007, and shortly thereafter secured seed funding from Y Combinator.[10] Dropbox officially launched at 2008's TechCrunch50, an annual technology conference.[14]

Due to trademark disputes between Evenflow (Dropbox's parent company) and Proxy, Inc., Dropbox's official domain name was "getdropbox.com" until October 2009, when they acquired their current domain, "dropbox.com".[14]

OPSWAT reported in their December 2010 Market Share report that Dropbox held 10.41% of the worldwide Backup Client market, based on number of installations.[15]

In May 2011, Dropbox struck deals with Japanese mobile service providers Softbank and Sony Ericsson. As per the terms of the deal Dropbox will come preloaded on their mobile phones.[16]

In May 2010 Dropbox users in China were unable to access Dropbox. Later, Dropbox confirmed they had been blocked by the Chinese Government. Due to the fact that the censorship usually focuses on popular services only, many considered this evidence of Dropbox's rapidly rising popularity and international user base. Up to Nov 2011, the website is still blocked in China, but locally installed applications are usable with some ISPs.[17][18][19][20][21]

As of October 2011, Dropbox had more than 50 million users.[22]

In April 2012, Dropbox announced a new feature allowing users to automatically upload photos or videos from camera, tablet, SD card or smartphone. Users will be given up to 3 GB extra space for their photos and videos collection. It is viewed as a move against Google's recently launched Google Drive and Microsoft's SkyDrive. [23]

Financials

Dropbox has received a total venture capital funding of $257.2 million from several investors, including Y Combinator, Sequoia Capital and Accel Partners.[24]

According to speculation, Dropbox's valuation is more than $1 billion.[25] TechCrunch, VentureBeat, Business Insider and Financial Post have also speculated that Dropbox's valuation could be as high as $5 to $10 billion.[26]

Dropbox's annual revenue is expected to reach $240 million in 2011.[22]

Dropbox is based in San Francisco, and is funded by Sequoia Capital, Accel Partners, and Amidzad.[10] Starting in mid-2009, they began releasing new features gradually to help measure customer interest, a Lean Startup technique.[27]

On April 3, 2012, Dropbox announced Bono and The Edge, two members of the Irish rock band U2 were individual investors in the company.[28]

Business model

Dropbox operates on the Freemium financial model.[29]

Dropbox offers paid accounts of 50 GB, 100 GB, and a team account of 1 TB or more.

The free account and the paid account are identical in all aspects except for the amount of storage space offered. According to CEO Drew Houston, Dropbox provides free accounts because: "Most of our growth is word of mouth/viral, so free users are still valuable: we grow faster, and they refer people who might pay ... Picking the right duration is tricky, and people add files to their Dropboxes at different rates. Many pay eventually after using the free service for a long time."[30]

In October 2011, Forbes published that Dropbox had 50 million users, of which 96% were using a free account.[22]

In 2009 Dropbox implemented a referral program[31] giving users extra space for referring new users. As of April 2012 both the referrer and the new user get additional storage space (500 MB for free accounts, 1 GB for Pro accounts). A referrer can refer several new users, getting extra space for each one.

According to Drew Houston at the Startup Lessons Learnt Conference on April 23, 2010, the referral program was inspired by the Paypal Sign up Bonus program. The referral program was successful and increased signups by 60%.[32] Referrals accounted for roughly 35%[33] of their daily signups (as of April 2010). In the 30 days before the conference presentation, Dropbox estimated that their users had sent 2.8 million[34] direct referral invites to their friends.

For a short time Dropbox operated an affiliate program whereby third parties which referred customers to Dropbox were paid commission, but this was discontinued in 2009 as an unwise use of resources[35].

Technology

Both the Dropbox server and desktop client software are primarily written in Python.[36] The desktop client uses GUI toolkits such as wxWidgets and Cocoa. Other notable Python libraries include Twisted, ctypes, and pywin32. Dropbox ships and depends on the librsync binary-delta library (which is written in C).

The Dropbox client enables users to drop any file into a designated folder that is then synced with Dropbox's Internet service and to any other of the user's computers and devices with the Dropbox client.[37] Users may also upload files manually through a web browser.[38]

While Dropbox functions as a storage service, its focus is on synchronization and sharing. It supports revision history, so files deleted from the Dropbox folder may be recovered from any of the synced computers.[39][40] Dropbox supports multi-user version control, enabling several users to edit and re-post files without overwriting versions.[41] The version history is by default kept for 30 days, with an unlimited version called "Pack-Rat" available for purchase.[42]

The version history is paired with the use of delta encoding technology. When a file in a user's Dropbox folder is changed, Dropbox only uploads the pieces of the file that are changed when synchronising, when possible.[43] The desktop client has no restriction on individual file size; files uploaded via the web site are limited to not more than 300 MB per file.[44] To prevent free users from creating multiple linked free accounts, Dropbox includes the content of shared folders when totaling the amount of space used on the account.[45]

Dropbox uses Amazon's S3 storage system to store the files;[46] though Houston has stated that Dropbox may switch to a different storage provider at some point in the future.[47] It also uses SSL transfers for synchronization and stores the data via AES-256 encryption.[48]

Power users have devised a number of innovative uses for and mash-ups of the technology that expand Dropbox's functionality. These include: sending files to a Dropbox via Gmail; using Dropbox to sync IM chat logs; BitTorrent management; password management; remote application launching and system monitoring; and as a free Web hosting service.[49][50][51][52][53][54]

Functionality

Add-ons

There are official and unofficial Dropbox addons, mostly created by the Dropbox community. These addons are both in the form of web services such as SendToDropbox[55] (which allows users to email files to their Dropboxes), Backup Box (which facilitates online backup of FTP, Git, MySQL, and other services to Dropbox accounts),[56] and desktop applications such as MacDropAny[57] (which allows users to sync any folder on their computer with Dropbox). There is also a web services and browser extensions called cloudHQ for Dropbox[58] which allows Dropbox users to synchronize Google Docs with files in Dropbox storage and also to edit Dropbox documents in the browser.

There are a number of client applications for operating systems that Dropbox does not officially support, such as Maemo, Symbian, Windows Phone and webOS.

An open source tool called Dropship provides unauthenticated access to Dropbox-hosted files by using the Dropbox API to access files by their hash. Dropbox attempted to suppress this project by requesting its suspension where it was being hosted, and by issuing a fake DMCA takedown notice, later said by Dropbox to be "a mistake".[59]

Dropbox user demographics

A plurality (32.7%) of Dropbox users are from the United States, with 6.7% and 6.5% from the United Kingdom and Germany, respectively. 66.1% of Dropbox users use Windows only, 20.9% use Mac OS only, 2.0% use Linux only, and the remainder use some combination of the three.[60]

Reception

Dropbox has been praised by many publications—including The Economist, The New York Times, PC Magazine, and The Washington Post—for its simple design and ease of use.[61][62][63][64] It has also received several awards, including the Crunchie Award in 2009 for Best Internet Application, and Macworld's 2009 Editor's Choice Award. It was nominated for a 2010 Webby Award, and for the 2010 Mac Design Awards by Ars Technica.[65][66][67][68]

Dropbox has been named as the world's fifth most valuable web startup after Facebook, Twitter, Zynga and Groupon,[69][70][71] has been touted as Y Combinator's most successful investment to date,[72] and is among the top 10 iPhone most popular apps of all time, according to TechCrunch.[73] Other accolades include being voted among the top 10 Android apps of all time, according to ZDNet,[74] being recognized as one of the top 50 emerging companies by TIEcon,[75] and called one of the 20 best startups of Silicon Valley.[76] Drew Houston was called the best young tech entrepreneur by Business Week,[77] and he and co-founder Arash Ferdowsi were named among the top 30 under 30 enterpreneurs by inc.com.[78]

In January 2012, the company was honored as start up of the year by Tech Crunch.[79]

Dropbox has been criticized by independent security researcher Derek Newton, who has argued that Dropbox's authentication architecture is inherently insecure,[80] and by software expert Miguel de Icaza who claims that Dropbox's terms of service contradicts its privacy policy and that the company's famous claim "Dropbox employees aren’t able to access user files" is a lie.[81]

In May 2011, a complaint was filed with the US FTC alleging Dropbox misled users about the privacy and security of their files. At the heart of the complaint was the policy of "deduplication", where the system checks if a file has been uploaded before by any other user, and links to the existing copy if so; and the policy of using a single AES-256 key for every file on the system so Dropbox can (and does, for deduplication) look at encrypted files stored on the system, with the consequence that any intruder who gets the key (as well as Dropbox employees) could decrypt any file if they had access to Dropbox's backend storage infrastructure.[82]

On June 20, 2011, all Dropbox accounts could be accessed without password for 4 hours as reported by TechCrunch. The error was caused by a code update made at 1:54 pm Pacific Time. The error was detected at 5:41 pm and immediately fixed. Fewer than 1 percent of Dropbox's users were logged in at that time. All logged in sessions were ended since then. All users with compromised accounts were notified by email.[83][84] Dropbox could potentially face a class action lawsuit over this incident. The lawsuit is being initiated by Cristina Wong of Los Angeles and claims violation of the California Unfair Competition Law. The suit has been filed as Wong et al. v. Dropbox Inc., No. 11-CV-3092-LB, (N.D. Cal. June 22, 2011). The suit is scheduled to be heard by U.S. Magistrate Judge Laurel Beeler.[85]

Headquarters

Dropbox had premises at 760 Market Street, and moved to larger premises in July 2011.

From that date Dropbox's corporate headquarters are at Suite 400[86] on the fourth floor of the China Basin Landing building in San Francisco.[87] The company occupies the fourth floor of the 1991 section of the facility, with 85,600 square feet (7,950 m2) of space, and an option to take more space.[88]
