Ehsan's Recommendation

The 80/20 of this stack: 80% of the value comes from automated data flow between ai writing and finance tools. With ChatGPT feeding into Brex, you remove the biggest friction point in most finance ops workflows. The biggest wins come from the second and third workflows you build, not the first. Plan for iteration.
