In October 2014, ConvertKit was pulling in $1,207 a month and sliding toward zero. Nathan Barry's fix wasn't a new feature, a funding round, or a bigger ad budget… it was lasering in on exactly who ConvertKit was not for.

The jump in ConvertKit's monthly recurring revenue, from $1,207 to $5,020, in the five months after Nathan Barry stopped chasing every email marketer and rebranded around one narrow buyer.

Nathan Barry started ConvertKit in 2013 to fix his own frustration. He was self-publishing design books and used email to sell them, but the tools built for generic email marketing didn't fit how creators actually worked. That's a fine reason to start a company. But it's a terrible way to define a market. When Barry described who ConvertKit was for, the honest answer was "anyone trying to build an audience quickly and sell products online", a category so wide it included Mailchimp.

And Mailchimp was a tough competitor to go up against. By the end of 2014, it had served roughly 14 million users, scaling up to a $12 billion valuation when Intuit bought it in 2021. And a three-person bootstrapped startup with no ad budget and generic positioning couldn't out-market that.

The deeper problem was who that vague positioning actually attracted. ConvertKit Academy, an education-first funnel Barry launched in mid-2014, brought in beginners chasing their first email list. These users were a headache to deal with. They complained about the price and were quick to cancel their subscriptions when their inconsistently ran projects stalled. Even worse, it made established creators with real audiences look at ConvertKit as a product built for hobbyists, assuming it wasn't serious enough for them. In Barry's own words, ConvertKit was "driving away our best customers and focusing on those least likely to succeed."

That's the trap generic positioning sets in a crowded category: it doesn't just fail to attract the right customers, it attracts the wrong ones, which ultimately end up costing more than they’re worth. ConvertKit wasn't losing to Mailchimp on features. It was losing because it didn’t laser in on who it was fighting for.

Barry's big insight was figuring out targeting. He noticed a pattern: the accounts that stuck around, paid on time, and grew fastest weren't beginners starting an audience from scratch — they were people with audiences who happened to be switching providers. So in late 2014, Barry changed ConvertKit's entire positioning to target one specific buyer. First it was "email marketing for authors," which was changed to "email marketing for Professional Bloggers" after noticing "authors" attracted too many hobbyists.

Narrower targeting changed everything downstream. Barry started direct sales for the first time, tracking every conversation on a Trello board and cold-emailing the top sellers on LeanPub and Udemy. A hundred personal emails converted five to seven customers, which wasn’t bad at all for a company that size. The team tackled the biggest objection prospects had by offering free concierge migrations, personally moving a blogger's entire list, tags, and automations over from a competitor.

The results showed immediately, with MRR growing by 54% in December 2014. The team kept narrowing their ICP: they started specifically targeting bloggers with mailing lists between 30,000 and 250,000 subscribers, because these prospects were big enough to afford the product and small enough that ConvertKit's white-glove migration was still the right amount of service.

That same instinct didn't stop once ConvertKit was healthy. In 2021, when ConvertKit already served over 365,000 creators and generated $27 million in annual recurring revenue, it acquired FanBridge, a 15-year-old email platform built exclusively for musicians. But even this wasn't a broadening move. ConvertKit followed the same niching-down logic: acquiring a company that had already done the narrowing work inside an adjacent creator vertical rather than trying to build music-specific trust from zero.

That same year, Spotify approached Barry about acquiring ConvertKit outright for what he later described as "hundreds of millions" of dollars. He turned it down. Staying independent meant staying free to keep narrowing the company around creators specifically, rather than folding it into a platform built to serve someone else's roadmap.

The line from that October 2014 bottom to today is close to a straight upward march. MRR hit $5,020 by March 2015, then doubled to roughly $10,000 by June as the "professional bloggers" positioning kept converting buyers on repeat. By 2022, ConvertKit, a company fully bootstrapped, profitable, and without a single dollar of venture capital, had hit $33.5 million ARR. But just two years later in 2024, the company crossed $43.8 million, serving roughly 49,000 paying customers, nearly 36 times the monthly run rate that almost got shut down a decade earlier.

In late 2024, ConvertKit made the logical next move and formally became Kit, positioning itself as an "operating system for the creator economy" rather than an email tool that happens to serve creators. The niche wasn’t dried up at all. In 2023 alone, Kit creators sent 902 emails every second, up 70% from two years earlier, and nearly a fifth of surveyed users said their creator business earned more than $100,000 a year.

The company that resulted looks nothing like the one that tried to be "email marketing for anyone." It's smaller than Mailchimp by orders of magnitude, and it's fine with that, because it never needed Mailchimp's addressable market, it needed the slice of that market that Mailchimp's generic product structurally couldn't serve well. Competition inside that slice has since arrived, from Substack and Beehiiv among others, but Kit is still fighting for a category it defined on purpose, not a category it fell into by trying to be everything to everyone.
