July 2009

Humble Beginnings

The journey to HackerRank first began in July 2009, when computer science graduates Vivek and Hari worked at Amazon and IBM (respectively) for about a year in Bangalore. Both were on interview panels, inundated with endless hours of resume reviews, phone screens, and onsite interviews. Unqualified people were making it to the onsite, while some of their most capable, hardworking friends were passed on because of their GPA or lack of a prestigious degree.

That’s when they noticed a massive problem—and opportunity—in the technical recruiting system. They quit their jobs to build InterviewStreet, a website that matched mentors with students. Within a few weeks, hundreds of students signed up across a dozen universities. They received their first cheque for 250 INR ($5). A copy exists in the Bangalore office and underneath, it says “Humble Beginnings.”

September 2010

Y Combinator

As time went on, students grew to love InterviewStreet. The only problem was that they weren’t able to sufficiently monetize the interview preparation website. By September of 2010, Vivek and Hari were almost bankrupt.

It was time to pave a new path. They applied to the seed accelerator Y Combinator (YC) in Palo Alto. In 2011, YC invited Vivek and Hari to their summer incubator program, where they received mentorship and $200,000 in funding to take their startup to the next level. The duo made history as the first Indian-based founders to graduate from YC.

Introducing HackerRank

Vivek and Hari raised Series A of $3 million, led by Khosla Ventures in September 2011. Within a year, they pivoted to building a platform that helps companies identify the right developers based on the results on coding challenges. Early customers who tried out the coding challenges included Airbnb, Box, and Amazon. Thus began Vivek and Hari's pursuit of a larger mission: matching every developer to the right job.

1+ Million Developers

Without even spending $1 on marketing to developers, the HackerRank community organically grew to 1,000,000 developers by February 2015. We continued to invest in helping developers by expanding challenges to a variety of different technical tracks, like SQL challenges, tutorial challenges, and more. These new challenges doubled down on helping developers improve their skills by matching developer skill proficiency to the right challenges.
