Sundae is a residential real estate marketplace that buys homes directly from homeowners for cash and resells them to a vetted network of property investors. Sellers get a competitive as-is cash offer with no repairs, showings, or fees, flexible closings in as little as 10 days, and an optional cash advance before closing; investors access off-market and distressed properties through the Sundae Marketplace. Backed by QED Investors, Sundae operates a consumer-facing website, an investor marketplace, and an agent referral program. It is a proptech/fintech company and, as of this enrichment pass, publishes no public developer API, documentation, or SDK surface.
