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

The episode opens with a cold-open montage that previews its most personal moments: a psychedelic experience at the start of the newsletter, the milestone of a newsletter launched in 2019 that now counts 1.2 million subscribers, the conviction that the best advice comes from practitioners, and an image of relentless weekly output. These clips set the tone for a conversation that is less a tactical playbook than a reflective, personal account.

Lenny explains the premise. Listeners have long asked him to sit on the other side of the microphone, and he chose his wife, Michelle Rial, as the interviewer. He promises to share things he has never shared anywhere else, including some of the hardest moments of the journey, and notes that Michelle is about to publish her third book, a children's book called Charts for Babies. The intro also carries sponsor reads for WorkOS and MetaView, which are advertising rather than part of the interview.

I get a lot more personal than I've ever been on this podcast.

Michelle frames the scale of what he has built: a newsletter started in 2019 with over a million subscribers (Lenny corrects her to 1.2 million) and a podcast that regularly ranks among the top 10 tech podcasts. She then recalls that when they met he was a software engineer, and the two trace his path from software engineer to product engineer to product manager.

Asked what he would be doing without the newsletter, Lenny describes the options he laid out after seven years at Airbnb. None of them involved writing. While he tinkered with startup prototypes, writing was a side activity, and Michelle at the time questioned it as a way to make a living.

Plan A: start a company again.

Plan B: join a startup as its first PM.

Plan C: join a big company as a PM.

Plan D: advise companies as a consultant.

It seems like there's a pull here, so I'm just going to keep doing this.

Michelle softens the memory, noting that as a writer herself she makes no money from posting online unless people buy her book. Lenny's honest answer to the counterfactual is unglamorous: he would probably have started another company, probably failed since most startups do, and then joined some company as a PM.

Lenny rejects the idea of one pivotal moment. He describes following a pull that was starting to work, and identifies several signals along the way. His first post on the internet, about what he learned at Airbnb, was featured by Medium and shared by Brian Chesky with the whole company. A few more Medium posts confirmed that people seemed to like his writing.

A conversation with his friend Lee Jacobs, now a VC, reframed his doubts. Lenny had been telling himself he should focus on the startup; Jacobs pointed out that he seemed to enjoy writing and people seemed to value it, a rare overlap that might one day also make money.

how often do you enjoy something and people value it and maybe there's a way to make money in the future?

The commercial turning point came after nine months of weekly posts on Substack. Lenny invoked the Lindy effect, the idea that something likely lasts at least as long as it already has, to conclude he could keep going for another year. He added a paywall, and the timing was forced by circumstance: his plan had assumed his Airbnb stock would be worth something, and when COVID hit and Twitter was full of "RIP Airbnb," he needed income. The paywall worked, and he made meaningful money within a month.

Michelle catches an omission in his Venn diagram. He had listed being good at it and people liking it, but the third circle, actually enjoying the work, matters too. Lenny agrees and connects it loosely to Ikigai, while admitting he is not sure of that framework's exact components.
