Building a Total Addressable Market Model in Alteryx?

[Dan5]

Hi All, 

I have worked with simple Alteryx Transforms to build a model that estimates spending power of a group of companies based on past spending behavior of similar companies. It seems like an ideal use case for a machine learning model, but I dont have any experience doing this in Alteryx (or elsewhere..)

1. I have historical spending data for customer in various industries, locations, revenue bands, etc.
2. I have an expected overall market size, and growth rates.
3. I have a list of global white space companies that I would like to estimate spending power for. - Its kind of a market allocation problem, but I would like to be as accurate and automated as possible..

Any examples or advice? I suspect I should be looking at Regression modeling, but am open to all options
