Lenny’s Newsletter ARR: Every Number Lenny Rachitsky Has Actually Disclosed

Lenny's Newsletter is the benchmark every paid-newsletter founder measures against — but its ARR has only ever been disclosed in fragments. Here's the dated paper trail, assembled, with the arithmetic labeled.

Lenny Rachitsky has never published a single tidy ARR number for Lenny’s Newsletter. What exists instead is a paper trail of dated disclosures — from him, from Substack, and from analysts who’ve tracked the newsletter obsessively — that brackets the answer well enough for anyone deciding whether the paid-newsletter business is real. Assembled in one place:

The disclosed timeline

DateFree subscribersPaid subscribersRevenue signal
April 7, 2020Paid tier launches ($15/mo, $150/yr)
May 2020 (~first weeks)~13,000~480~$56K gross annualized
End of 2020~45,000~3,300~$300K+ first-year revenue
2023–24 analyses377,000+18,000+“over $2M” a year from paid

The early rows come from Substack’s own case study of the launch and from Growth In Reverse’s long-running teardown of the newsletter; the 18,000-paid figure is from the same analysis, originally published in 2023 and updated through 2024.

The implied conversion rate has wandered — under 4% in the first weeks, above 7% at the end of 2020 — before settling at the roughly 4–5% of free readers paying the latest counts show.

What the arithmetic says today

Price times payers is the whole model, so label the estimate and do it:

Gross: $2.7M+

18,000+ paid subscribers at $150 a year, if everyone paid annually.

Net: mid-$2M

After Substack’s 10% platform cut, payment fees, and the mix of monthly plans — squaring with the “over $2 million annually” language in the 2024-updated analyses.

Every part of that math is an estimate built on disclosed inputs, not a disclosed total. Lenny’s actual current number could sit meaningfully above it, since the subscriber base has kept growing past the last public count.

And the newsletter is no longer the only line.

The SaaS lens

Why a one-person media company clears $2M

Read it the way you’d read a SaaS company and the shape is startling.

ACV: about $150

Deep consumer-prosumer territory, where the go-to-market math says you cannot afford any sales or paid acquisition.

CAC: effectively zero

Growth came from free essays compounding through search and sharing, exactly the organic motion Webflow used at $40/month price points.

Gross margin

A rounding error below 90% after Substack’s cut.

The famous retention lever

The software bundle he attached for annual subscribers, offering free years of tools product people already wanted, turned $150 from a considered purchase into an obvious trade for its audience.

What the model lacks is just as instructive: there is no expansion revenue, no seats to add, no usage to grow into. A subscriber is worth $150 next year too, or nothing. That caps net revenue retention below 100% by construction — the ceiling every media-subscription business shares, and the reason a newsletter at $2.7M gross and a SaaS company at $2.7M ARR are worth very different multiples.

The honest bottom line

Fragmented as the disclosures are, they describe one of the highest-margin one-person businesses ever documented: roughly $56K annualized in month one, $300K+ in year one, and a seven-figure run rate by year three that has kept compounding since. If you want the equivalent picture for software companies — actual disclosed revenue, pulled from the founders themselves — that’s what we build at getlatka.com.
