The number of new unicorns born in the fourth quarter last year declined sharply from the third quarter, from 23 to nine worldwide. As the "smart money" dries up, identifying the most promising new startups gets even more interesting.

ROKO Labs thinks it has come up with a way to predict which companies are most likely to beat a possible bubble burst. The mobile platform company used Crunchbase data to identify early-phase startups that have funding from at least three "unicorn hunter" investors, or investors known for backing startups that have grown to a private valuation of more than $1 billion.

On the list:, Minio, Drafted, Cadre, StreamSets, LearnUp, WayUp and Cockroach Labs. 

ROKO cofounder and president Amy Kadomatsu says the startups have proven their mettle, despite a tightening funding climate. "You see a whittling down of the number who are kind of really at the highest level of investment," she says.

ROKO's infographic, below, offers insight into what these startups have in common.

Editor's note: This story has been modified to reflect changes ROKO Labs made in the infographic. After Y Combinator reported it had invested in more startups on the original list of 10 than cited, Y Combinator and ROKO Labs agreed to remove the accelerator and include only venture capital firms in the infographic. As a result, startups Eden and Paribus no longer appear in the infographic. The title of this post has also been changed to remove the number "10."
