Number of employees
More than 100,000 graphic designers and writers from 200 countries work on Crowdspring.
When it launched publicly in mid-2008, the company and its business model received some criticism because Crowdspring's marketplace works on a speculative model and challenges traditional ways of buying and selling graphic design, industrial design, and copywriting services. This is the process of asking professionals to complete custom work for the chance of getting payment. This means that most people involved in the process effectively work for free. Crowdspring embraced and actively participates in the debate about its spec work business model.
