I wanna sleep with you again, because of that glint.

For start ups such as Glint, this desire for oversight is a lucrative business opportunity.

When you're scared or surprised, or both at once, there's a funny glint in your eyes.

Glint secured 10 million in November from Bessemer Venture Partners, bringing its total funding to 60 million.

Both Glint and Convercent offer their software as a service, charging companies recurring fees to use their products.

Errett said she gained more insight into what her employees were thinking and feeling in three years using Glint.

He saw that first glint of light he knew what the weather was going to be three days from now.

And as he talked he had that glint in his eye that I first saw back in Holland the glint that says, Let's go cow tipping, even though we never did tip the cow, even though no one tips the cow, even though cows don't sleep standing up.

Like Glint, Convercent lets companies send customized pulse surveys, gather confidential responses in real time, and view heat maps of its problem areas.

Madison Reed, which now does monthly employee surveys, has been able to take action the same day a problem is reported on Glint, according to Errett.

You've got a blue glint too, like a splinter of chalcedony, a dimple in your chin, and your hair looks like you got it cut in a juvenile detention center.

You've now got tools such as Strava and Fitbit for tracking your health, but where's the Fitbit for your company? said Jim Barnett, co founder and chief executive of Redwood City start up Glint, whose software analytics tools are used by companies to measure employee engagement.

When people are happy to be at a company, feel their voices are heard, and that the work they are doing is rewarding, they are more committed to making that company successful, said Nina McQueen, vice president of global benefits and employee experience at LinkedIn, which uses both Convercent and Glint.
