The Power of the Crowd is an important driver for innovation and problem-solving for all organizations that want to commit to quality and long-term success. Established corporations, SMEs, non-profits and public organizations are using open and engaged online communities to solve their problems, see the example of NASA. These organizations are also known in the field as the Problem Owners.

Problem Owners interact with such communities and “fish” for solutions and technologies for a variety of reasons:

  • General technology/solution scouting
  • Solve a specific problem
  • Find talent for hiring purposes
  • Engage with general public/communities
  • Employer branding

Usually from the Problem Owner’s side the persons managing the challenge are members of the innovation team and/or from the specific group that has the problem to be solved. Business, design and more techy profiles, can be found in the teams promoting this kind of initiatives. They look for passionate and motivated individuals ou groups to enlarge their knowledge regarding a given issue and bring diversity into the process.

Corwdsourced problem-solving is a big opportunity for freelancers, coders, designers, scientists, students and even Startups to learn, improve skills or validate technologies. These are known as the Problem Solvers.

Problem Solvers look for acquiring or improving skills, meet think-alike people, know companies, meet opportunities and, of course, make money! The members of these online communities are moved by fun, prizes or glory, or all at the same time. This can mean being recognized by their expertise among influent people/recruiters or take it as a side hustle and make an extra income.

This list has some examples of ways to benefit from this phenomenon. There’s a challenge for any kind of person with any level of expertise or skill. The types of platforms/communities in this article are:

  • General Innovation Challenges: Ranging from well-known and defined problems like helping with the HR department to retain talent through Machine Learning to wicked and open ones like the space poop challenge. Depending on the circumstance the problem solver could either submit the solution individually or in group (or startup).
    Some of the challenges require truly specialized knowledge while others look for creativity rather than technical expertise.
  • Programming Competitions: There is an abundance of coding platforms either to learn from scratch or to practice. They provide a wide range of languages and tasks to progressively augment the coders capabilities. In this list only the platforms that allow to monetize the coding skills were considered.
  • User Research: Targeted at UX/UI professionals or general community, these platforms allow anyone to earn cash by reviewing websites and apps. All companies now have an online presence and for optimization reasons and user experience improvement, they often run tests with a restrict group of people to collect valuable insights.
    Most common tests take 15/20 minutes and the participant has to follow predefined guidelines and navigate through the website or app and verbalize his/her experience. Both the audio and the screen (sometimes de face) will be recorded to be further analysed by the test owner. The increased quality of the test can get to a better paycheck.
    All you need: Computer, tablet or smartphone, wi-fi connection, a quiet place and to install a little piece of software (most of the times).

The list has no particular order, no criteria was taken to present it as it is other than grouping them by themes. Each platform as a small description, useful info regarding the monetization potential and relevant links. Any comment or question is welcome!
