Teller is a fully transactional banking API for your existing bank account. Its API enables developers to build applications that connect with their users’ bank accounts in a manner that is much more times reliable, predictable, performant, and fair than anything else available.
This seems like something that should be a solved problem in the present but before Teller, the state of the art was to rely on antiquated techniques such as screen-scraping online banking HTML pages. Of course, these pages were never designed for this so it’s no surprise that anything using this approach is hopelessly broken.
Banks do have real APIs. Externally facing APIs are necessary for their apps to work, they would just rather you don’t have access to them. Teller aims to reverse engineer these apps to discover their secret API contracts and then implement clients for them. Teller's approach has enabled it to deliver a solution that is a 100x improvement and has led to promising early funding which will help boost the company going forward.
