ConvertKit (Kit) Revenue: The $43.8M Number That Almost Died at $1,337 a Month (2026)

Quick answer (2026): Kit, the creator-focused email marketing platform formerly called ConvertKit, is privately held and fully bootstrapped, so it has never published audited financials. Third-party trackers put its 2024 revenue at about $43.8 million (GetLatka), up from $36.4 million in 2023, while research firm Sacra pegged it at roughly $38 million ARR in late 2023 on zero capital raised. Founder Nathan Barry still controls the company. But the number that actually explains Kit is not $43.8M. It is the $1,337 a month the business shrank to in September 2014, when Barry came close to shutting it down.

Most "convertkit revenue" searches want the big, round figure. This one only makes sense read in order, because the interesting part is not where the company landed. It is the month it almost ended, and the boring decision that turned it around.

How much revenue does ConvertKit (Kit) make?

Kit is a private company with no outside investors, so there is no income statement to pull. Every figure below is either founder-reported (Barry published ConvertKit's monthly recurring revenue openly for years) or a third-party estimate. Here is the honest, source-typed ledger instead of one confident number:

Two of those rows disagree on purpose. For 2023, Sacra's run-rate read is about $38M while GetLatka's trailing figure is $36.4M. That couple-million-dollar gap is not an error. It is what "revenue" looks like for a company that files nothing: outsiders triangulate from headcount, pricing, and customer counts rather than reading audited books, so the honest answer is a tight range, not a decimal.

Read the column top to bottom and the shape is unusual. Most SaaS ledgers climb in a straight line. This one dips hard in the middle, in 2014, and nearly flatlines before it moves.

The $1,337 month

Barry launched ConvertKit in 2013 as a side project alongside his design books, and for more than a year it went sideways. By his own public accounting, revenue drifted down to $1,337 per month in September 2014, below where it had started. In October 2014 he did the thing most founders avoid: he put $50,000 of his own money into the company and gave himself a deadline.

The math was brutal and he wrote it down at the time. By May 2015, he noted that "we aren't growing fast enough so that our revenue ($8,500) matches our expenses ($13,000/month) before we run out of the $50,000 I invested." A monthly loss of roughly $4,500 against a fixed runway is the kind of number that ends companies. It is the single most important row in the ledger above, because everything after it is a consequence of what he chose to do next.

The unglamorous fix: selling one blogger at a time

Barry's answer was not a growth hack. It was manual, direct, and completely unscalable, which is exactly why it worked. He started reaching out to individual bloggers one at a time, offering to show them ConvertKit over a 30-minute Skype call, and then personally migrating their email list and automations off their existing tool for them. He called it a concierge migration. He did the tedious export-import work himself so the switching cost, the thing keeping people on Mailchimp, effectively went to zero.

The receipts show up fast in the ledger. MRR hit $10,000 in June 2015, jumped to $18,296 in August, reached $24,699 in September, and broke $30,000 a month in October 2015. Seven months earlier the same business was losing money at $8,500. The lever was not a feature. It was a founder doing work that did not scale until it did.

From $30K a month to $43.8M a year

Once the base was solid, the compounding took over. Kit sells subscriptions on a list-size ladder, roughly $9 to $25 per month at the low end scaling up for larger senders (Sacra, 2023). GetLatka's trailing figures trace the climb: $5.8M in 2016, $13.2M in 2018, $19.8M in 2019, $25M in 2020, $29M in 2021, and $36.4M in 2023, reaching an estimated $43.8M across 49,000 customers in 2024.

Two engines drove the later years. Sacra reported that growth had re-accelerated to 22% year over year by late 2023 after slumping to just 3% in October 2021, helped by two network products: a Creator Network that lets writers recommend each other's newsletters, and a Sponsor Network that matches businesses with writers to sponsor. Kit also pushed into paid subscriptions and commerce for creators; the company said in August 2026 that creators had earned over $10 million through its commerce product since 2022.

The number that actually explains Kit

Here is the figure almost no "convertkit revenue" write-up bothers to compute. At $43.8M across 149 employees, Kit runs at roughly $294,000 of revenue per employee. That is a genuinely efficient number for a company with a free tier and a heavy support load, and it is a direct descendant of the concierge-migration years: Barry built a machine that keeps customers rather than one that constantly replaces them.

The retention data backs that up. Sacra reported Kit hit 100% net dollar retention in 2023 with gross revenue churn of 3.1%, its lowest month on record, and 25% expansion revenue growth. Net dollar retention at 100% means the existing customer base pays for itself even before a single new signup; expansion from creators growing their lists offsets the ones who leave. For a bootstrapped company with no war chest, that retention profile is not a vanity metric. It is the thing that makes the whole model survivable without outside money.

Why bootstrapping let Barry say no to $200M

Owning the company outright bought Barry the one thing venture-funded founders rarely have: the option to decline. In his own words, "In 2021, Spotify reached out to buy @ConvertKit for hundreds of millions. I said no." The offer has been widely reported at around $200 million. With no investors on the cap table pushing for an exit, that was his call alone to make, and he kept the business.

Contrast that with the venture-funded side of the same market. Substack and beehiiv both raised large rounds to chase the creator-newsletter category; Mailchimp, the incumbent Kit spent years pulling customers away from, exited to Intuit for about $12 billion. Kit took a different road entirely, and it is the only one of them where the founder still answers to no one.

The $360K rebrand: ConvertKit becomes Kit

In June 2024, Barry announced the company was dropping the ConvertKit name it had used for a decade and rebranding to Kit, complete with an app store and a platform strategy aimed at third-party integrations. He has since described the rebrand as an expensive bet, reported at roughly $360,000 on the Ahrefs Podcast. That is why you now see the revenue tracked under both names: the legal entity and the numbers are continuous, only the brand changed.

What operators can take from the Kit number

The $43.8M is a lagging indicator. The decision that produced it was made in October 2014 at $1,337 a month, when Barry chose to double down and do the unscalable work instead of quitting. Three things travel from Kit's ledger to a smaller operator's desk:

• Your revenue curve is set at the trough, not the peak. The interesting month is the one where the number goes down and you decide what to do about it.
• Do the work that does not scale for longer than feels reasonable. Concierge migrations carried Kit from a monthly loss to $30K MRR in seven months. Retention, not acquisition, is what those manual years bought.
• Ownership is a number too. Zero capital raised is why a nine-figure offer was a choice and not a foregone conclusion.
