TopCoder

Topcoder was founded in 2001 by Jack Hughes, chairman and Founder of the Tallan company. 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.

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. From 2006 onwards, Topcoder held design competitions, thus offering design services to their clients. In 2006 Topcoder also started to organize Marathon Matches (MM) – one week long algorithmic contests.

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.

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.

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.

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.
