Episode notes
Postscript Built A Live Sales Center To Learn SMS Playbooks
- Postscript built an e-commerce sales center and hired sales reps to text shoppers, running hundreds of thousands of conversations and driving hundreds of millions in revenue.
- They encoded those learned playbooks into AI rather than using a generic LLM wrapper.
Feed Product Data And Voice Into Conversational AI
- Create a Brand Center with product data, PDPs, and voice guidelines so conversational AI answers are accurate and on-brand.
- Integrate Shopify metafields and PDP content to fine-tune the model before launching Shopper agents.
Real Time Replies Are A Short Window Arbitrage
- Consumer response-time expectations are low today (only ~16% expect <1 minute), creating an arbitrage for brands that reply in real time.
- Fast replies will become baseline as AI adoption grows, so early adopters gain advantage now.
