The term “crowdsourcing” was originally coined by “Wired Magazine” writer Jeff Howe in 2006 and is a combination of the words “outsourcing” and “crowd”. Outsourcing traditionally describes transferring work processes from your own company to an external service provider in order to use the economies of scale involved and minimize costs. A crowd generally describes a large number of individuals who form a community.

The principle therefore describes a process in which companies outsource parts of their work processes and fall back on a community of thousands of people (the crowd) instead of individual service providers. Companies, so to speak, work with the “intelligence of the masses”. Individual persons who participate in the crowd are called crowd workers or clickworkers often registered on crowdsourcing platforms.

Crowdsourcing works with or without payment. The best-known example of a project in which crowd workers are not paid is the online encyclopedia Wikipedia.
It is a crowdsourcing platform everyone can work with and everyone can complement or change. But crowdsourcing is not only divided in regard to finances but also in regard to its different types and application areas.

Crowdsourcing – Development

Although Web 2.0 was conducive to set the “knowledge of the crowd” into motion, it was used much earlier. For example in 1879, when James Murray, the philologist and editor of the Oxford English Dictionary, asked his English-speaking readers to provide references for unusual as well as standard words. This resulted from the desire to create a dictionary of the English language that documented the origins of the words. However, the founders of the Oxford English Dictionary soon realized that the task could not be mastered by single persons and that they would have to recourse to the help of the crowd. The response was overwhelming and resulted in the most extensive and significant English dictionary.

Today the Internet offers new, improved forms of cooperation with the crowd. The obvious benefit is the speed with which the crowd of users can be activated in the Web. Platforms such as Wikipedia pool the knowledge of all participating users; on WikiLeaks anonymous whistleblowers disclosed secret documents pertaining to public matters, and fans can support their favorite projects on the funding platform, Kickstarter.

Crowdsourcing Platforms – Main Types

Types of Crowdsourcing Platforms


Crowdtesting is inviting and receiving feedback from a subset of your target audience to identify issues or problems with a product (often apps and websites). This gives you more visibility into how the product is being used and what challenges the audience may be having when interacting with your product (including technical bugs or usability issues with apps and websites).

The term crowdfunding is used when the crowd finances projects or the development of new products. The crowd can sponsor projects via special platforms; in this case, special emphasis is placed on the non-material aspect. However, crowdfunding is also used as a means of preliminary financing in the United States. A provision is disbursed to the sponsors if the project is successful at the end.

In engagement and charity the term reveals that the crowd is expected to donate something. However, in this case the focus is on non-profit projects. Money donations are accepted but the organizations are just as happy to receive donations in kind such as food or clothing, as well as the involvement of voluntary helpers for various projects and events.

Collaborative Knowledge

The term collective knowledge describes the collection as well as filtering and organization of knowledge. In so-called group or collective intelligence many users put their knowledge at the disposal of the crowd. Wikipedia is an excellent example of this phenomenon. Likewise, the assessments or decisions of a large pool of different people can deliver equally good results as those of an expert in his field. So-called prognosis platforms make use of this principle.

Open Innovation

Open Innovation is a form of collaboration that aims to bring together diverse stakeholders and build new solutions for problems by expanding the traditional boundaries between business sectors. The most common type of open innovation is between firms and organizations that offer complementary capabilities.

Open innovation in crowdsourcing is the process of engaging diverse, external people in order to generate new ideas and solutions. Open innovation relies on a team or community approach so that different perspectives and knowledge can be shared.
Companies sometimes outsource their innovation process and strive, with the help of the crowd, to create new product ideas, produce, optimize and market products. This process can also be used to develop problem-solving solutions. High customer satisfaction is guaranteed thanks to the wide range of persons participating.

Creative Crowdsourcing Platforms

Creative and design crowdsourcing involves soliciting feedback from a large group of people to develop ideas, products or services. Creative crowdsourcing can include anything such as websites, apps, or even video games.
In addition, the creative crowd is also used to create graphic designs such as logos, brochures, advertising material, etc. Companies and private individuals offer creative tasks on numerous platforms; these jobs are more complex and better paid because they demand expert knowledge. As already mentioned before, these can include the creation of websites, banners or logos.


Microtasking is a type of crowdsourcing where individual tasks are assigned to small groups. Microtaskers can either be individuals or an organization that divides the work amongst its members. Microtasking is often used for tasks that require small individual steps, like writing a blog post or doing research.

Crowdsourcing Microtasking

When it comes to microjobbing or microtasking very small tasks, so-called microtasks, are offered to a large group of Internet users. In most of the cases these microtasks result out of a major project that has been divided into many similar subtasks.

The crowd is always a good choice whenever companies have to handle a larger number of tasks in a relatively short period of time. The use of the crowd makes a large number of workers available on demand without creating any overhead costs. Therefore, when demand is irregular, a company can make use of the manpower of thousands of workers on a flexible basis.

It goes without saying that the crowd is best used for tasks that are easily divided into individual microtasks and then reassembled to a convincing overall result after completion. In addition, the task that is being outsourced must not require any profound knowledge of your own product or company. This is essential to ensure that a sufficient number of qualified workers are available to implement the project in a short period of time and provide satisfactory results.

There is an empty canvas. You may place a tile upon it, but you must wait to place another. Individually you can create something. Together you can create something more.– Reddit Place

Reddit Place 2022

Creative Crowd – An unusal, recent Example

To illustrate the system a bit, we can look at Reddit’s recent crowd experiment.

Originally intended as an April Fool’s joke in 2017, the “Place” project was repeated in 2022. In the beginning there was an empty canvas of four million (2000 × 2000) pixel squares. For 4 days, every Reddit user was able to color a pixel of their choice on a small cooldown of a few minutes.

Several subreddits coordinated to claim and decorate certain sections of the canvas for themselves. It was only through this collaborative effort of over 6 million participating users that this breathtaking result could be achieved in the end. The development of the canvas can also be viewed as a time-lapse video.

Real-World Examples of Crowdsourcing

Through the practice of “crowdsourcing,” a group of people can contribute their expertise, opinions, or resources to a task or project. Crowdsourcing can be used to solve a wide variety of tasks, from developing a new product to conducting market research. Crowdsourcing can be used to gather data, create new ideas, or solve a problem.

Below are a few real-world examples of crowdsourcing.

  1. Waze
    Traffic apps are designed to help drivers avoid accidents by providing them with up-to-date information about traffic conditions in their area. Traffic apps rely on the contributions of thousands of “citizen scientists” who use their smartphones to report road incidents and traffic congestion. This data helps traffic engineers develop better algorithms and make more informed decisions about how best to manage traffic flow. Waze is one of the most popular crowd-powered startups. Users of the app can report traffic congestion, and the app will also suggest the best route to travel. Waze gathers information from users by asking them to report road closures and tracking driving speed to identify traffic jams.

  2. Wikipedia
    One of the earliest applications of online crowdsourcing is Wikipedia. In 2001, Wikipedia launched a free, web-based, multilingual, and collaborative encyclopedia based on a non-profit business model. Wikipedia is currently the most widely used encyclopedia on the internet. With 17 million pages authored collectively by the community, it aims to be “The sum of all human knowledge in one place.” Collectively and without compensation, community members have written every page. Wikipedia users have the option to contribute anonymously and articles can be created or revised by anyone with a computer.

  3. CitySourced
    An industrial platform for civic involvement is called CitySourced. Citizens can discover and report non-emergency civic issues like public works, quality of life, and environmental issues using the CitySourced mobile app. The service is a component of the e-Government or “gov 2.0” movement, which attempts to use technology to establish a connection between the government and its constituents.

  5. Zooniverse
    Given the size of the universe, it would take an enormous quantity of data to fully understand all of its complexities. Through the Moon Zoo crowdsourcing project, which Zooniverse established, regular people can examine and arrange high-resolution lunar photos. Four million lunar photographs have been studied so far.
