We all love to posts fun party pictures of ourselves on Facebook, or share a rant on Twitter.
But if you're job hunting, TMI like that can really hurt you.
Enter Rep'nup. It's a service that sifts through your social media accounts and finds the damaging photos and helps you hide or delete that stuff.
This is actually a really hard technical problem for a computer to know that a photo of you drinking a glass of orange juice is A-OK, but drinking a screwdriver? Maybe not, CEO Lior Tal told us.
So its founders are scientists and experts in machine seeing where computers learn to understand a photo.
And, this is the third startup for Tal, who co-founded database security company Guardium acquired by IBM for $225 million and Insightix bought by McAfee.
