After my HN debut two years ago, PropBox.co has evolved from an advertising platform called ziphomez to a complete MVP SaaS low-flat-fee solution for residential home transactions. What began as a physical model in 1989 that ultimately failed has finally found its digital wings in March 2025. To the 273 commenters who offered guidance, your feedback helped shape our new platform—Thank You. Persistence outlasts failure. The best innovations sometimes take many years to realize fully. Never give up.
