Summary List PlacementThings have not gone according to plan for fintech startup Plaid. But its investors now say that may be for the best. In January, Visa agreed to purchase the fintech unicorn for $5.3 billion, giving Plaid's backers a sweet return on their investment — roughly seven years after the company raised its first round of venture capital. But the deal fell apart on Tuesday, after regulators refused to approve it and instead sued to stop it, saying it was anti-competitive. In the face of that, both parties agreed to walk, they said in a statement.
