How to show up in any room with a low heart rate: Silicon Valley’s missing etiquette playbook

Executive Summary
Lenny's Podcast episode, sponsored by TenWeb and DX, in which Lenny Rachitsky talks with Sam Lessin, partner at Slow Ventures, former VP of product at Facebook and two-time founder, about his etiquette playbook for founders. Lessin argues that as software commoditizes, trust decides deals, and etiquette is the skill of showing up in a room with a low heart rate: abundance over scarcity, relationships over business cards. He gives concrete rules - say great to see you instead of nice to meet you, keep fragrance subtle, remember B for bread and D for drinks, tip without making it the story, keep business email short and emoji-free, and order recipients by importance. He closes with his investing view that AI is a propellant, not a startup thesis, and that he backs companies needed because of AI rather than AI companies. PARTIAL COVERAGE: the captions cover most of the conversation, but this summary highlights the core etiquette rules only, so most of the ten book categories and the lightning round are not covered. These are Lessin's own opinions, not independently verified, and nothing here is investment advice.
Key Takeaways
Why etiquette, why now
Lessin says trust is the scarce asset when technology stops being a sideshow, so meeting people where they are is a business tool.
Low heart rate
He frames etiquette as showing up calm and abundant, because transactional desperation scares people off.
Great to see you
He recommends the phrase because it works whether or not you have met, avoiding the embarrassment of guessing wrong.
Don't be the story
He says tipping, fragrance and ordering should never be what people remember about the dinner.
Email is a monologue problem
He treats long email as talking at someone for ten minutes, and ranks recipients so the most important comes first.
Emojis are familiarity
He says emojis are a step of intimacy that business contexts have not always granted, so match before using them.
AI is propellant, not thesis
As an investor he backs companies that use AI or exist because of it, not companies whose plan is to win because of AI.

Core Frameworks & Ideas
Abundance over scarcity - Lessin's room rule
Enter every room as if this is one of many opportunities, not your only shot.
Match the room - his mirroring principle
Read vocabulary, emoji use and formality, then match them rather than imposing your own.
Propellant test - his AI investing lens
Ask whether a startup wins because of something else with AI accelerating it; if AI is the whole plan, pass.
Actionable Next Steps
- ✓Swap nice to meet you for great to see you this week.
- ✓Cut your next business email to the point and order recipients by importance.
- ✓At your next dinner, handle the tip quietly and early.

Sam Lessin's case for etiquette: when product alone no longer differentiates, the founder who shows up calm, generous and predictable wins the room.
