When Visa bought Plaid this week for $5.3 billion, a figure that was twice its private valuation, it was a clear signal that traditional financial services companies are looking for ways to modernize their approach to business. With Plaid, Visa picks up a modern set of developer APIs that work behind the scenes to facilitate the movement of money. Those APIs should help Visa create more streamlined experiences (both at home and inside other companies' offerings), build on its existing strengths and allow it to do more than it could have before, alone. But don't take our word for it. To get under the hood of the Visa-Plaid deal and understand it from a number of perspectives, TechCrunch got in touch with analysts focused on the space and investors who had put money into the erstwhile startup.
