10 Examples of IT Outsourcing: Outstanding Software Built by Remote Teams

Without further delay, these companies have embraced the distributed development model, which helped them unlock new levels of productivity, creativity, and collaboration:




Now one of the leading platforms for software development and version control, GitHub made a strategic decision to outsource the development of its MVP. The CEO and co-founder of GitHub recognized the importance of finding a backend developer with extensive knowledge and expertise in Gits, a crucial aspect of their platform. They came across Scott Chacon, who possessed a rare understanding of Gits at that time. In response to the founders’ request, Chacon joined the GitHub team as a consultant on an outsourced basis.

Chacon’s involvement proved to be pivotal as he took on the responsibility of developing the backend of GitHub’s website. His understanding of Gits and his technical skills allowed him to build the robust foundation that became integral to the platform’s functionality.




To conserve raised funds, Slack chose to outsource design and app development services right from the beginning. They hired a Canadian design team to assist in the development of their product, starting from the beta version, and this external team played a crucial role in refining and enhancing the user experience of Slack’s website and mobile app. They also took charge of redesigning the company’s logo and creating the visual elements that users interact with while using the messaging service.

Within just two weeks after its launch, Slack managed to acquire an impressive user base of 15,000 users. This early success propelled the company’s growth trajectory, leading to its eventual status as a startup unicorn in 2014 and attracting considerable investor attention.




Initially, Opera received financial support from its parent company, Telenor. However, when Opera transitioned into a separate entity, its available resources became more constrained. In order to efficiently manage its development process while considering the skills and capacity of developers, Opera went for remote software development services.

This outsourcing case study example can teach companies how to optimize limited resources. Opera could tap into a global talent pool, selecting developers with the required expertise and experience to contribute to its platform. And they only committed to in-house operations after determining the critical areas that required internal expertise.




In its early days, back in 2012, WhatsApp was a small organization with limited resources, comprising just 30 full-time employees and five part-timers. With only $250,000 raised in seed funding, the company couldn’t keep the costs reasonable while competing against established players in the market, particularly SMS technology.

To tackle this obstacle, WhatsApp opted to outsource the majority of its essential development work to an external partner. They understood the importance of finding web development experts who offered a combination of high quality and cost-effectiveness.

Therefore, they turned to Eastern Europe, a renowned outsourcing hub known for its talented IT professionals, to meet their requirements. Just two years after its outsourcing decision, the company achieved an important milestone when it was acquired by Facebook for a staggering $19 billion.




Skype, founded in 2003 by two entrepreneurs from Sweden and Denmark, outsourced its development work to three professional developers from Estonia. Working together, the founders and the Estonian developers successfully created the widely recognized and beloved communication platform known today.

One of the Estonian developers played a crucial role in introducing the concept of cost-effective voice calls through a P2P protocol. Additionally, Skype’s innovative features, such as video chat, instant messaging, and file transmission, have made it an indispensable tool for individuals and businesses alike.

The success of Skype was evident just two years after its inception when it was acquired by eBay for $2.5 billion in 2005. This marked a significant milestone for the company. Subsequently, in 2011, Microsoft acquired Skype for an even more substantial amount, reaching $8.5 billion.


Innovative Marketing Automation Platform


When the first contacts were made, the Client required additional engineering resources to accelerate the development and release of new software features. The company was searching across the market to find contractors that would ensure the following:

  • Expert knowledge in building and managing full-stack dedicated development teams;
  • Developers on staff available to join the project and start delivering results asap;
  • Efficient recruitment efforts to adjust development team composition as required.

As of November 2022, the cooperation is still underway. The Customer is fully satisfied with the quality of provided works and plans on outsourcing more subprojects to GP Solutions.



During the 1990s, Jack Ma, the founder of Alibaba, faced major challenges due to limited resources and the complexities of operating in China’s restricted internet environment. The scarcity of Chinese specialists in e-commerce development added another layer of complication. With a modest initial investment of $20,000, Jack Ma recognized the need to look abroad for the website development of his startup.

Alibaba began seeking partners and outsourced various projects to overseas professionals, particularly in the United States. This move paid off in remarkable ways. Alibaba’s growth trajectory soared to unprecedented heights, culminating in a historic achievement in 2014 — the company secured its place in the annals of business history by executing the largest IPO ever witnessed.




Google is known for its vast in-house workforce of over 178,000 employees, but it still finds itself facing monumental workloads that require additional support. Therefore, the company leverages the power of outsourcing by tapping into the global talent pool and partnering with contractors. One prominent example is Google’s Ads project, a cornerstone of the company’s revenue generation in 2017. To ensure the seamless functioning of this robust service, Google has enlisted the expertise of more than 1,000 outsourced representatives hailing from over 60 countries.

In fact, the reliance on outsourcing has grown to such an extent that, as reported by Bloomberg, the number of Google’s contractors exceeded its direct employees for the first time in 2018. The significance becomes even more evident when we consider the magnitude of Google Ads, a tool that captures the attention of marketers worldwide by reaching over 90% of internet users.

Leading European Ferry Line Operator


The project was initiated by a leading cruise operator which manages a large fleet of cruise ferry ships traveling from Estonia to Finland, Estonia to Sweden, Latvia to Sweden and Finland to Sweden. It is one of the largest passenger and cargo shipping companies in the Baltic region.

The company requested GP Solutions to develop and support their own web portal for online booking of cruises. The requirement was to implement a fast and reliable booking engine that would include a bonus program and the option to choose a different route when users do their return trip.
