A startup launched by Tigran Sloyan and Aram Shatakhtsyan in 2014, CodeFights let’s individuals challenge each other in solving computer programming problems. The winner of each game, or “code battle”, earns points and moves on to more advanced levels and stiffer competition. It’s a great way for programmers to test their coding skills against one another, and it looks very addicting from the comments we’ve read from players. Based in San Francisco, CodeFights has just scored $2.4 million in seed funding. A notable backer of the startup is Raffi Krikorian, former VP at Twitter. The company even has several job opportunities in Armenia. Check out this video of co-founder Tigran Sloyan describing the concept of CodeFights.
