Awards and Honors

In 2010, he won the Netexplorateur Prize[4] for creating the GiveWork iPhone app,[5] which allows users to perform small tasks that assist refugees and people in developing countries. Later that year, Inc. Magazine included Biewald and Van Pelt on its list of the Top 30 Entrepreneurs Under 30.[6]

Biewald and Van Pelt launched CrowdFlower as a product of Dolores Labs at TechCrunch50[7] in 2009, where the company placed as a finalist.

He is the author of several academic papers[8][9][10] on applications of crowdsourcing, as well as a chapter on crowdsourcing gender and age stereotypes[11] in O'Reilly Media's Beautiful Data that he co-authored with Brendan O'Connor.

Academic Life

Biewald holds an MS in Computer Science and a BS in Mathematics from Stanford University.

While pursuing his Master's in Computer Science at Stanford University, Biewald won the California Institute of Technology Turing Tournament.[12]

gollark: I feel like they could probably just, if it's for array literals, get away with limiting it to 16 or so with no major issues.
gollark: It's allegedly to make neater bytecode.
gollark: This code is a TOTAL apiohazard.
gollark: Maybe some sort of abstract interface for them which is implemented by the class.
gollark: No, no, you need to have a class for this instead of regular booleans, plus a factory.
