Zillow is its own brokerage now, currently managing their ibuyer leads with in-house agents, but I suspect they will slowly phase out their premier agents as well, and do what Redfin does, but with 4 times the traffic and leads. Jack Ryan needs to either join a non-realtor association owned mls or create his own and get other alt-brokerages on it, because there is strength in numbers. Search portals like Zillow can ignore REX listings without losing any consumers, but not thousands of listings across dozens of alt-brokerages
