I'm not familiar with the Marmer model, and also don't see how it is really different from the Customer Development Model, with the exception that it puts timeframes to each stage. I think the Funding Stages model is completely wrong. How many people are able to raise a round of funding without proving product market fit. I see it more as Financing Model might follow Customer Centric or Marmer.
