Saama Hackathon 2017

16 innovative teams, equally crazy ideas, 24 hours of battle, indiscriminate doses of caffeine, Live Band, cool tech talks came together to result into one hell of a Hackathon! Join Aijaz Ansari as he revisits Saama’s first ever Hackathon that produced some novel ideas and discoveries. Relive the hacker within you!

This year, on March the 2nd and 3rd, Saama’s offices were abuzz with fervour action as the participants readied themselves for a tech-battle to claim the title of being the ‘Coolest Saama Techie’. What each team planned to build was special – DIY project that teams themselves chose. After a preliminary evaluation round based on the novelty of the idea and the real-world application of the project, we set sail on our very first Hackathon journey. “All aboard!”

Hackathons (codefests or hack-days) have been around for a while and people from Saama have been participating in a few, on their own. Growing event popularity with Saamaites inspired us to host one internally too. And the response was astounding. 16 teams (of 3 member at the max) signed up to participate. They packed for 24 hours with all the tech they could lay their hands on. We just ensured there was enough healthy food, people to cheer and an unlimited dose of lemonade, coffee and colas!

Here’s rounding up awesome projects and cool techies but first some numbers;

48 participants

16 projects

4 panellists

400 in audience and…

Amazon’s Echo Dot, Raspberry Pi and Chromecast up for grabs!
