Topcoder (formerly TopCoder) is a crowdsourcing company with an open global community of designers, developers, data scientists, and competitive programmers. Topcoder pays community members for their work on the projects and sells community services to corporate, mid-size, and small-business clients. [1] [2] [3] Topcoder also organizes the annual Topcoder Open tournament and a series of smaller regional events.



Topcoder was founded in 2001 by Jack Hughes, Chairman and Founder of the Tallan company. [1] [2] The name was formerly spelt as "TopCoder" until 2013. Topcoder ran regular competitive programming challenges, known as Single Round Matches or "SRMs," where each SRM was a timed 1.5-hour algorithm competition and contestants would compete against each other to solve the same set of problems. The contestants were students from different secondary schools or universities. Cash prizes ranging from $5,000 to $10,000 per match were secured from corporate sponsors and awarded to tournament winners to generate interest from the student community. [1]

As the community of designers, developers, data scientists, and competitive programmers involved in Topcoder grew, the company started to offer software development services to 3rd party clients, contracting individual community members to work on specific tasks. Most of the revenue, though, still came from consulting services provided to clients by Topcoder employees. [1] [4] From 2006 onwards, Topcoder held design competitions, thus offering design services to their clients. [1] In 2006 Topcoder also started to organize Marathon Matches (MM) – one week long algorithmic contests. [5] [note 1]

In an attempt to optimize expenses, Topcoder introduced new competition tracks in 2007-2008 and delegated more work from its employees to the community. By 2009, the size of Topcoder's staff had been reduced to 16 project managers servicing 35 clients, while the community did most of the actual work via crowdsourcing. Topcoder representatives claim that at this point their community had about 170k registered members, and the company's annual revenue was approximately $19 million. [1] [6]

In 2013, Topcoder was acquired by Appirio, and the Topcoder community (of around 500 thousand at the time), was merged, under the Topcoder brand, with the 75k member crowdsourcing community Cloudspokes, created and managed by Appirio. [7] [8] [9]

In 2016, Topcoder, along with Appirio, was acquired by Wipro as a part of a $500 million deal and continued to operate as a separate company under its brand. [10] [11] [12] [13] [14]

Since the end of 2017, Topcoder has continued to offer its enterprise clients the Hybrid Crowd platform, as a way to protect intellectual property in crowdsourcing projects. In addition to the public Topcoder community, the Hybrid Crowd platform allows for the creation of certified and private crowdsourcing communities. Its certified communities include members of public Topcoder communities who are vetted for a customer's specific requirements, such as signing an additional NDA, completing a background check, or meeting any other particular certifications. The private communities may include an enterprise's employees and contractors. As the first user of Hybrid Crowd, Wipro integrated its internal (employee-only) crowdsourcing platform TopGear with Topcoder. [15] [16] [17] [18]

Topcoder community is the primary source of the workforce behind all Topcoder projects. It is open and global: anybody, with a few legal restrictions dictated by US laws, and listed in Community Terms, can join and compete, without any financial commitment to Topcoder. Also, participation in challenges organized in the interests of commercial clients generally requires the community member to sign a non-disclosure agreement. Intellectual property for the winning submissions to commercial challenges is passed to the client, in exchange for monetary prizes paid to the winners. [24] [25]

While the majority of community members participate in Topcoder challenges as regular competitors, those who become recognized for their performance, and involvement in community life (via communication in Topcoder forums, attending Topcoder events, etc.), are offered additional roles in the community, which include: copilots (technical coordinators of challenges), problem writers, reviewers, etc. [24] Since the end of 2014 till the end of 2017, a Community Advisory Board (CAB) was selected from active community members for a one-year term to help improve communications between Topcoder company and its community. [26] [27] [28] [29] In 2018 the CAB was replaced by the Topcoder MVP (Most Valuable Player) program. [30] [31]

There are four primary segments of each Topcoder community, open to every member: Design, Development, Data Science, and Competitive Programming. [24] Also, since the end of 2017, Topcoder, as a part of their Hybrid Crowd offering, creates sub-communities dedicated to specific clients/projects. The sub-communities may require members to meet additional eligibility criteria before joining. [32]


Topcoder design community is focused on: [33]

Two particular types of Topcoder design challenges are LUX (Live User Experience, 24 – 48 hours long) and RUX (Rapid User Experience, three days long). In both cases, more substantial prizes compared to regular design challenges with the similar goals, are offered in exchange for the shorter timeline. Short timelines allow Topcoder managers to demonstrate to customers how crowdsourcing works on real cases, during live, and few-days meetings with the clients. [33]


Software development segment of Topcoder community is focused on: [34]

Data science

There are several types of data science challenges at Topcoder; typically, they are longer than software development challenges and focused on data science and algorithms, rather than on end-user software products: [36]

Competitive programming

The Competitive Programming track of Topcoder community rotates around Single Round Matches (SRMs) – timed 1.5-hour competitions in which all participants compete online trying to solve the same set of problems as fast as possible. These were the first type of challenges at Topcoder. [1] [39]

Specialized sub-communities

The following table includes the list of Topcoder sub-communities dedicated to specific technologies and/or clients (within their Hybrid Crowd offering). See TopCoder § Notable Clients and Projects section for further information on these sub-communities.

Topcoder Open

Topcoder Open (TCO) is an annual design, software development, data science and competitive programming championship, organized by Topcoder, and hosted in different venues around the US. Each year, the most successful participants of each competition track included into TCO are selected and invited for a free one-week trip to on-site finals, where they compete for prizes, and also socialize with each other, helping to build community spirit among the most active members. In the first two years, 2001 and 2002, the tournament was titled TopCoder Invitational.

In addition to the main championship, from 2001 to 2007 Topcoder organized an annual TopCoder Collegiate Challenge tournament, for college students only. Also from 2007 to 2010, a TopCoder High School competition was held.

Since 2015, Topcoder Regional events have been held through the year in different countries.

Crowdsourcing Obtaining services, ideas, or content from a group of people, rather than from employees or suppliers

Crowdsourcing is a sourcing model in which individuals or organizations obtain goods and services, including ideas, voting, micro-tasks and finances, from a large, relatively open and often rapidly evolving group of participants. Currently, crowdsourcing typically involves using the internet to attract and divide work between participants to achieve a cumulative result. The word crowdsourcing itself is a portmanteau of crowd and outsourcing, and was coined in 2006. Crowdsourcing is not necessarily an "online" activity and existed before Internet access became a household commodity.

Automated Artificial Intelligence (AutoAI) is a variation of the automated machine learning, or AutoML, technology, which extends the automation of model building towards automation of the full life cycle of a machine learning model. It applies intelligent automation to the task of building predictive machine learning models by preparing data for training, identifying the best type of model for the given data, then choosing the features, or columns of data, that best support the problem the model is solving. Finally, automation tests a variety of tuning options to reach the best result as it generates, then ranks, model-candidate pipelines. The best performing pipelines can be put into production to process new data, and deliver predictions based on the model training. Automated artificial intelligence can also be applied to making sure the model does not have inherent bias and automating the tasks for continuous improvement of the model.
