For every billion dollar unicorn, there are endless numbers of start-ups that have passed into the ether — laying off their engineers in matching, branded t-shirts; closing down their game rooms filled with ping-pong tables; and leaving heartfelt goodbye notes for customers on their soon-to-be defunct websites.

We're halfway through 2017 and already a group of startups that together raised $1.48 billion have shut down.

From February's shuttering of Beepi, a used car exchange once valued at $560 million, to this week's closure of gadget maker Jawbone, which was once worth $3 billion, these are the start ups we've lost so far in 2017 — and one whose demise looks imminent. May they disrupt in peace.
