This thread is "completely unrelated to this blog post" and your previous comment was responding to comments about the US ACH network.
Do US fintechs offer something similar? Perhaps, but I bet it works pretty differently to BACS where the bank already knows about the money transfer.
The feature is based on the predictable pattern of payroll direct deposits, and/or a pre-settlement view into the ACH transfers for the day. The latter sounds like what you are describing for BACS, but I don't know the UK details.
