How Smartcard Coin Bounced Back From Near Failure

Coin, a smartcard startup, had that experience after much fanfare and an impressive crowdfunding campaign.  The YC-backed company raised $50,000 in less than an hour.  The concept — to store all your credit cards, membership cards, and gift cards on a single card — quickly accrued a fan following. But the product didn’t deliver; the first iteration was plagued with problems.  Last year, Coin bounced back with version 2.0.  Turns out that a failed launch isn’t the end of a company.
