Stack Exchange, Inc., the New York, NY-based operator of Stack Overflow, a site where developers have built a large online repository of programming knowledge, raised $40m in Series D funding.
The round, which brought total venture funding to $70m, was led by Andreessen Horowitz with participation from existing investors Bezos Expeditions, Index Ventures, Spark Capital, and Union Square Ventures.
The company intends to use the funds to accelerate the growth of Stack Overflow to serve programmers on a broader scale including investing additional resources into talent site Stack Overflow Careers, localized versions of Stack Overflow in Japanese, Russian, and Spanish, as well as on-going support and growth of Stack Exchange Q&A communities.
Founded in 2008 by CEO Joel Spolsky and Jeff Atwood, Stack Exchange operates a large network of websites for software developers including Stack Overflow, a site for programmers to find, ask, and answer their questions serving more than 26 million professional and novice programmers each month. It has also expanded to cover topics as diverse as Mathematics, Home Improvement, Statistics, and English Language and Usage.
