Best Crowdsourcing Platforms

Crowdsourcing has grown rapidly over the past decade, establishing itself as an invaluable tool for businesses, organizations, researchers, and creative professionals. Put simply, crowdsourcing leverages the knowledge, skills, and perspectives of a large, diverse group of people to accomplish a wide range of tasks and goals.

Whereas traditionally, tasks and projects were handled in-house by employees or contractors, crowdsourcing opens up participation to the public. By tapping into the collective intelligence and manpower of the crowd, it becomes possible to achieve outcomes that may have been too costly, complex, or time-consuming for any one person or organization to undertake alone.

Crowdsourcing comes in many different forms and serves many different purposes. Some common examples include crowdfunding campaigns that democratize access to capital, design contests and innovation challenges that harness creative talent, and distributed human computing platforms that parcel out micro-tasks to online contributors. No matter the application, crowdsourcing makes it simple and affordable to access specialized skills, novel solutions, diverse perspectives, on-the-ground data collection, and scalable workforces.

As crowdsourcing has matured, dedicated platforms have emerged to connect requesters and contributors for specific needs. Today, leading crowdsourcing platforms channel the crowd’s productive power toward everything from data processing and transcription to graphic design, market research surveys, product development, writing, and more.

This guide takes an in-depth look at the top 10 crowdsourcing platforms shaping business and society today. It explains how each platform works, key benefits and use cases, and what makes the platforms stand out from the competition. Whether you’re exploring crowdsourcing for the first time or are already a seasoned user, this definitive guide maps the crowdsourcing landscape and showcases the extensive possibilities of harnessing the crowd.

What is Crowdsourcing?

Crowdsourcing is the practice of obtaining information or input into a task or project by enlisting the services of a large number of people, either paid or unpaid, typically via the Internet. The term was first coined by Jeff Howe in a 2006 Wired magazine article.

Some key aspects of crowdsourcing include:

  • Leveraging the “wisdom of the crowd” – large groups of people can collectively have more knowledge and better insights than any single individual. Crowdsourcing allows tapping into that collective intelligence.
  • Outsourcing work to a distributed group of people, often an online community. This allows work to be done more quickly, cheaply, and efficiently than traditional means.
  • Breaking large tasks into microtasks that can be completed rapidly by many people. This makes seemingly arduous jobs manageable.
  • Using competition to motivate participation. People are often willing to complete tasks for badges, prizes, rewards, or status in addition to payment.
  • Utilizing spare time and cognitive surplus. People in their free time can use crowdsourcing platforms as a productive way to earn money, contribute to projects, or develop skills.

So in summary, crowdsourcing leverages networked online communities and technology to divide work among a large decentralized group rather than localizing it to dedicated internal teams. This allows more work to be done, problems solved, data processed, and creativity unlocked.

Benefits of Crowdsourcing

Crowdsourcing can provide several benefits compared to traditional resourcing models. Here are some of the key advantages:

Access to talent

Crowdsourcing provides access to a large, global talent pool that would be difficult or impossible to reach through traditional hiring methods. Organizations can connect with freelancers, subject matter experts, and niche specialists around the world. This gives access to skills and knowledge that may not be available locally.

Reduced costs

By tapping into the on-demand global workforce, organizations can significantly reduce costs associated with permanent employees or traditional consulting models. Crowdsourcing provides access to talent and solutions at a fraction of the cost of traditional resourcing.

Faster results

Crowdsourcing makes it possible to parallelize work, splitting large projects into microtasks that multiple workers complete simultaneously. This dramatically reduces project delivery times compared to sequential working models. Complex projects can be completed in days or weeks rather than months.

Diverse perspectives

Tapping into a distributed, highly diverse global talent pool also provides access to far more diverse perspectives, ideas, and insights compared to traditional teams. This diversity of thought can spark innovation and creativity. Geographic, cultural, and experiential diversity avoids groupthink.

In summary, crowdsourcing provides flexibility, scalability, and diversity while driving down costs and accelerating results. The collective intelligence, skills, and creativity of the crowd can be more powerful than traditional resourcing approaches.

Crowdsourcing has emerged as a powerful way for businesses and organizations to leverage the skills, ideas, and work products of a global community. As we’ve seen in this guide, there are a variety of excellent crowdsourcing platforms that enable this connection.

Looking to the future, crowdsourcing appears poised for even greater growth and impact. As more complex tasks become automated by AI, crowdsourcing may evolve to focus more on creative, analytical, and interpersonal skills that remain uniquely human. New specialization, quality control, and worker reputation features on platforms will likely allow for increasingly sophisticated workflows.

Augmented and virtual reality could also unlock new crowdsourcing capabilities. As the global workforce becomes more connected, we may see large-scale collaborations on everything from scientific problems to humanitarian projects.

While challenges around data privacy, fair compensation, and platform governance remain, the crowdsourcing community continues to grow. Organizations are finding new ways to tap into on-demand talent pools, while workers have access to income opportunities beyond their local job market.

Ultimately, crowdsourcing allows new ideas and solutions to emerge that would never take shape within a single organization. As platforms, requesters, and workers refine their practices, this human-powered marketplace promises to keep making positive impacts for years to come.
