Biggest teaching moment ▶ 17:37 Deep dive into model fine-tuning mechanicsEvgeny educates Andrew on the technical complexities of audio transcription, LLM-as-a-judge scoring, and supervised fine-tuning epochs versus simple Zapier prompting.
Andrew holds their own ▶ 13:33 Andrew diagrams the voice automation tech stackAndrew demonstrates his automation expertise by mapping the exact integration chain from CRM triggers to Zapier, Vapi API voice calling, and calendar booking.
the scores for every segment, with the reasoning behind each
| Chapter | Topic | Andrew as informed peer | Guest teaching | Guest disagreement | Andrew pushing back | Why |
|---|---|---|---|---|---|---|
| The Cold Calling Grind in Real Estate | 2 | 6 | 1 | 3 | Andrew makes optimistic assumptions about expired listings having high conversion rates and asks why a 1-2% rate was frustrating. Evgeny educates him on real estate reality, explaining that disgruntled homeowners often reject agents and that 200 dials are needed just to reach one homeowner. | |
| Developing the First AI Voice Agent Prototype | 3 | 4 | 1 | 3 | Andrew challenges Evgeny on why he did not simply scale a real estate brokerage empire with his tool instead of pivoting to software. Evgeny explains his CS background and personality mismatch with the rigid, decades-old real estate business model. | |
| Client Acquisition and Early Low-Code Agency Architecture | 4 | 3 | 0 | 2 | Andrew digs into the lean customer acquisition funnel using native Meta lead capture forms without a landing page. Evgeny describes qualifying leads via Google Meet and screening out unqualified agents despite high demand. | |
| Voice Automation Workflows and Model Fine-Tuning | 5 | 7 | 1 | 3 | Andrew maps out how an agency could build outbound voice agents for other trades like plumbing using Zapier and Vapi. Evgeny explains that true conversational salesmanship requires complex supervised fine-tuning data pipelines and LLM-as-a-judge scoring rather than basic prompt engineering. | |
| Transition to Self-Serve SaaS and Onboarding Aiden | 3 | 2 | 0 | 1 | Evgeny discusses transitioning away from client services to build software full-time and finding Aiden via YC Co-founder matching. Andrew brings Aiden in to define operational responsibilities and playfully notes Aiden's persistent outreach. | |
| SaaS Customization, AI Coding Tools, and Company Naming | 5 | 5 | 2 | 4 | Andrew presses on why Evgeny shut down paying agency clients instead of maintaining a $50k/mo agency model. Evgeny explains that custom prompt adjustments were unsustainable, and breaks down why AI coding tools still demand deep software architectural knowledge. |
