This hits the real problem head-on — it's not just getting the form to send, it's getting the lead to the right person fast enough to matter. The 5-minute window you cite is the whole ballgame in real estate; after that, you're usually second in line. I especially liked the care around validation and tagging — a malformed phone number or an untagged lead isn't a small glitch, it's a lost deal that never shows up in any report. The before-and-after pattern is smart too, because it shows the work instead of just claiming it.
