57 startups became unicorns this year and seven lost...

The unicorn club gets new members by the week. This year alone, 57 startups around the world attained unicorn status with a valuation of $1 billion or more, according to data from venture capital tracker .

Seven companies that were once considered unicorns have seen their valuation dip below $1 billion so far this year, either through down rounds or down exits. Last year there were only three down rounds or exits. The Honest Company and Prosper both saw their valuation shrink below $1 billion in subsequent funding rounds, according to PitchBook. Down exits this year included , which was acquired by Amazon for $650 million, and Shazam, which for $400 million.

Overall 2017 wasn’t the biggest year for unicorns — that award goes to 2015, which boasted 81 new unicorns — but it certainly has been busy.

Social platform Reddit, bitcoin marketplace Coinbase and ride-hail company Careem are among the notable entrants this year. Synthetic biology company is the latest inductee into the group, thanks to a $275 million funding round last week.

Altogether there are now a total of 227 active unicorns, according to PitchBook.
