Door: Non-Traditional Brokerage Firm?

[Justin C.]

So I saw this today in my Dallas-area newsfeed:

It looks like the premise of the start-up is to fulfill the role of an agent and charge a flat fee as opposed to a 3%-6% cut of the transaction.

Has anyone tried using Door before, and what was your experience like?  I'm curious to see if experienced investors agree/disagree with the founder's arguments.  It strikes me that this company is trying to do with the real estate brokerage process what LegalZoom did to legal services in the early 2000s, and I'm curious whether this structure would provide the level of service you would want compared to a traditional agent.
