Redfin is a technology-powered residential real estate brokerage and listings portal founded in 2004 in Seattle by David Eraker, Michael Dougherty, and David Selinger.
Real Estate -- specifically residential brokerage, listings aggregation, and consumer home search. Consumers use Redfin to search MLS listings on a map, save favorites, schedule in-person or video tours with Redfin agents, view Redfin Estimate valuations, submit offers, and (increasingly) get pre-approved for mortgages through Rocket.
9/10. Redfin reports ~50 million monthly unique visitors, making it the #2 or #3 U.S. real estate portal behind Zillow and roughly tied with Realtor.com.
For a buyer's-agent brokerage, a Redfin lead agent's most critical operating data lives behind login: active client roster with contact info, scheduled tour pipeline, saved-home activity per client, offer history, deal-stage notes, commission splits, transaction documents, and post-close client follow-up.
Founded 2004; IPO 2017 (NASDAQ: RDFN); acquired by Rocket Companies in 2025.
Agents are overworked / on-call 24/7, leading to poor client service. Low compensation; draw clawed back at closing, low commission splits. Full sourced list under Sources below.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
