30. HackerRank

Gamifying job recruiting for techies

Founders: Vivek and Harishankaran Ravisankar
Date launched: 2009
Funding: $12.4 million
Industries disrupted: Job boards, recruiting firms

HackerRank is helping companies ask the right questions when they're interviewing IT professionals. Just think about it: HR folks are often tasked as the first interview point when companies are bringing on IT staff. The problem is, they often don't possess the technical know-how to differentiate between a so-so IT candidate and a great one. That's where HackerRank comes in. It gives companies the tools to create programming tests that actually screen for the IT skills a company is looking for.

Using the HackerRank's platform, a company can post their own coding challenges and use HackerRank's code checker to find the best candidate. Customers so far include Bloomberg, Goldman Sachs, Target, Wal-Mart and Amazon, to name a few.

The Mountain View, California-based company was started in 2009 by Harishankaran and Vivek Ravisankar, a former Amazon engineer, who was involved with interviewing tech folks at Amazon and saw firsthand how subjective and confusing the process could be. He figured there had to be a better way. Investors seem to agree. HackerRank has pulled in $12.4 million of financing from Khosla Ventures and Battery Ventures.

"The recruiting process for technical talent is broken today. ... Too many great programmers are passed on because they may not have the right degree or brand-name company on their résumé." -Vivek Ravisankar, HackerRank CEO
