Ask any fintech and they'll tell you - Plaid is simultaneously the best and worst vendor they use. Best because there's no real alternative, but worst because it causes so, so, so many headaches with how unreliable the product is. The time spent building product workarounds at every company to account for Plaid issues is tremendous.
If Stripe thinks they can build something better, then I'd really love them to try.
Edit: William (co-founder of Plaid) seems to have deleted his comment, but it was basically accusing Stripe of repeatedly copying other companies.
