Hallway Chat 2024
Open hallwaychat.co →Your sales calls are the cheapest customer research you will ever run: every objection, feature ask, and exact phrase a buyer uses is sitting in your transcripts.

The discipline that matters is prompting for evidence with quotes rather than summaries, so the AI cannot smooth over the uncomfortable patterns you most need to see.
