How I built a 1M+ subscriber newsletter and top 10 tech podcast | Lenny Rachitsky

From Airbnb PM to Newsletter Founder

Left Airbnb in 2019 with plans to start a company or join as a PM, not to write, but began sharing learnings on Medium while tinkering with startup ideas.

The Viral Spark

His first post 'What I Learned at Airbnb' went viral after Brian Chesky shared it company-wide, validating that his professional experience contained valuable insights.

The 9-Month Lindy Effect

After writing weekly for nine months, he applied the Lindy principle—if a thing lasts X time, it will likely last X more—to justify adding a paywall and committing full-time.

The Joshua Tree Revelation

During a three-hour psychedelic experience on a rock in Joshua Tree, the mantra 'I have wisdom to share' repeated in his mind, giving him the confidence to pursue writing despite having no formal plan to do so.

Engineering Happiness

A University of Pennsylvania course on the psychology of happiness taught him that baseline happiness can be intentionally increased through optimistic thinking and cognitive reframing.

Silent Meditation Foundation

Completed a 10-day silent meditation retreat that helped him manage stress and develop the mental clarity needed for consistent content creation.

Practitioner-Generated Value

Transitioned to primarily publishing guest posts from operators sharing the best lessons from their careers, believing the best advice comes from practitioners actively doing the work, not just reading about it.

The Indiana Jones Boulder

Describes the weekly publishing schedule as a relentless treadmill where finishing one piece immediately requires starting the next, creating constant pressure but also deep fulfillment.

Financial Necessity as Catalyst

Launched the paid subscription only after Airbnb's stock crashed, forcing immediate monetization out of financial need rather than waiting, which proved the model viable within the first month.

Genetic vs. Learned Resilience

Attributes 70% of his calm demeanor to genetics and 30% to active practices like meditation, breathing exercises, and deliberately reframing situations to not take them seriously.

The Three-Circle Venn

Sustainable creative work requires the rare intersection of being skilled at something, enjoying it, and people valuing it—missing any element makes the business model fail.

The 7-Year Lindy Horizon

Uncertain about long-term viability past retirement age, he uses the Lindy effect to project another seven years of sustainable content creation based on his seven-year track record.
