Hypothesis - Junior engineers take a lot of time integrating any Fintech API ( Investments, Payments, Lending etc) in their applications. Also its time taking to secure the payments data for any non fintech company because that its their core.
What id there is a low code platform wherein a dev select the the SDK and the service they want and simple integrate in their app.
Its like building mobile SDKs like Flutter, React Native, Android and IOS SDK on top of Plaid like APIs ( From multiple vendors) with customizable UI.
SaaS like pricing with an admin dashboard to manage integrations and check performance.
