Flexible options make it easy to be fully compliant with regulation - either through your own AISP / PISP licences or by acting as Bud's agent.

Tried and tested

Bud's technology was originally built alongside, and tested at scale by some of the largest and most complex financial institutions in the world.


We know that projects live and die by finding validation fast, so we designed our APIs from the ground up to be easy to implement quickly.

Bud's intelligence product sorts transaction data into more than 200 distinct categories - giving clients the flexibility to build genuinely useful tools and services

Flexible access to data

Open Banking is a great source of data but it's not the only one. Bud's intelligence product can accept data from both 1st party (your own) and 3rd party (e.g. other aggregators) sources..
