How to Select the Right Crowdsourcing Platform

Here is a step-by-step guide to help you select the ideal crowdsourcing platform for your needs:

1. Define Project Goals

Be clear about what you want to achieve from crowdsourcing. Consider:

  • What are the objectives and desired outcomes?
  • What‘s the acceptable error margin?
  • Will confidential data be shared with the crowd workers?

2. Understand Required Services

Research the platforms to find ones offering services that match your needs, such as:

  • Data collection and annotation
  • Content creation – articles, videos, designs etc.
  • Software development and testing
  • Innovation, ideas and surveys
  • Marketing and advertising related services

3. Consider Required Expertise

Evaluate if the platform‘s crowd workers have the domain expertise you need for your project. For example:

  • For medical image annotation, you need healthcare professionals.
  • For software QA testing, you need people skilled in relevant technologies.

4. Compare Pricing Models

Crowdsourcing platforms offer different pricing models:

  • Fixed price per project/task
  • Hourly rate per worker
  • Customer sets price per task, workers bid

Choose the model that aligns with your budget. Look for free trials.

5. Review Company Sizes

Bigger platforms may have larger crowds while smaller companies may be more specialized. Pick one with capacity to meet your work needs.

6. Check Online Reviews

Research crowdsourcing provider reviews on sites like G2, Capterra and TrustRadius to learn about quality of service.

7. Consider Data Security

If your project involves confidential data, pick a platform with security certifications like ISO 27001, GDPR compliance and data encryption.

8. Try a Pilot Project

Run a small pilot project first to test quality of work delivered before committing to a large program.

By evaluating your unique needs against platform offerings using these tips, you can identify the ideal crowdsourcing provider for your business.

Advantages of Crowdsourcing Platforms

Here are some key benefits of using crowdsourcing platforms:

Access Specialized Skills

Crowdsourcing platforms give you instant access to niche expert skills from global talent pools, without actually hiring. For example, get an aerospace engineer to help with a design issue.

Scale Workforce On Demand

You can scale up and down your workforce easily based on business needs. No need to hire, train or fire – just pay per task completed.

Diversity of Ideas

Tap into diverse perspectives from around the world to get innovative solutions to your problems.

Cost Savings

Avoid overhead of hiring full-time resources for temporary or niche skill needs. Pay only for work done.


Crowd workers can parallel process tasks rapidly. Things get done faster.


Customize projects easily by tweaking parameters like turnaround time, level of expertise required, number of workers etc.


Leading platforms provide security certifications and protections like ISO 27001 and GDPR compliance.

Risks of Crowdsourcing Platforms

While crowdsourcing platforms offer many benefits, some risks need mitigation:

Quality Control

Vet crowd workers diligently for skills, conduct audits, have QA reviews in place to ensure high quality output.

Data Security

Use platforms with security certifications and data encryption. Anonymize any confidential data shared with workers.

Lack of Loyalty

Don‘t share proprietary IP or long term business strategies. Handle core activities in-house.

Deadlines Missed

Have buffer for unexpected delays. Use platform SLAs. Build in redundancy by routing tasks to multiple workers.

The Future of Crowdsourcing Platforms

Here are some likely crowdsourcing trends to emerge in the near future:

  • Platforms using AI to automatically match tasks with best qualified workers
  • Blockchain based crowdsourcing platforms for enhanced transparency
  • Crowdsourcing of highly complex tasks like R&D by tapping niche expert communities
  • Consolidation of platforms and emergence of end-to-end solutions
  • Rise of vertical SaaS solutions with embedded crowdsourcing capabilities


This guide provides a structured way to compare and evaluate various crowdsourcing platforms as per your specific business needs. Choosing the right platform provider can help you access specialized skills on-demand and drive innovation by leveraging collective intelligence. Carefully weigh factors like security, quality control, pricing model and crowd capabilities when selecting a partner. Start with a pilot project to test the waters before diving deeper. The crowdsourcing landscape offers immense opportunities to gain a competitive edge if tapped judiciously after thorough due diligence.
