At OfficeNinjas HQ, we are constantly searching for the latest and greatest tech tools to help you be more efficient. Last week we traveled from SF to NYC to attend TechCrunch Disrupt – the largest, most coveted 3-day tech conference where hundreds of early stage tech startups from around the world gather to show off their products in hopes of becoming the next BIG thing. The conference also had amazing panels and fireside chats with tech industry’s leading superstars, such as Yahoo CEO Marissa Mayer, Founders of BirchBox and CEO of the controversially popular app Whisper.

The startups we met were all in different stages, some barely had a prototype while others had the product launched for a couple of years. There were so many new products we found fascinating for office pros that we’re going to share with you the most impressive ones in 3 separate blog posts. Because many of these products are brand spanking new, you may experience some kinks, but who knows, one of these apps may very well be the next Uber (now worth $4B in just under 5 years!).

Part 1: Roundup of 8 Killer Business Apps for Office Pros!

1. AirSig

AirSig uses fingerprinting identification to login to your mobile apps. Let’s say you want to login to your Facebook app. Simply hold your phone as if it was a virtual pen and write “FB” in the air and BOOM, you’re logged in to Facebook. The authentication technology recognizes your virtual penmanship thus making it impossible for others to login. We were so blown away that we had to take a video to share how it works.
