CrowdFlower Closes on a $10 Million Round Led by Microsoft


Data collection and cleaning platform CrowdFlower closed on $10 million in funding led by Microsoft Ventures. Also participating in the Series D round are Canvas Ventures and Trinity Ventures.

CrowdFlower’s funding now totals $38 million. The company will use the funds to speed adoption of CrowdFlower AI. 

The company gave a Best of Show-winning presentation at FinovateFall 2014 where it demonstrated how its on-demand workforce cleans and labels financial transaction data. Banks upload their data, define their task, and launch their job. CrowdFlower’s taskforce steps in to do what a computer can’t. The crowdsourced workforce completes micro-jobs to fill in holes in incorrect or incomplete data. The company leverages this effort in its recently launched CrowdFlower AI that combines human intelligence with machine learning to create what the company calls, Human-in-the-Loop, a product that uses active learning to make machine learning more viable.lukas_biewald

In a blog post, company CEO and founder Lukas Biewald (pictured right) says, “There are always places where algorithms struggle … . We’ve made it easy to automatically identify where machine learning is struggling and send them back to CrowdFlower jobs for humans to label.”

Founded in 2009, the San Francisco-based company’s customers include LinkedIn, Intuit, Flickr, and eBay.
