Kit, formerly ConvertKit, is an email marketing platform built for independent creators such as writers, podcasters and course makers. It was founded by Nathan Barry and renamed Kit in 2024.
What it is
The company serves creators who build an audience by email and earn money from it. It offers email newsletters and tools to grow and monetize a list. After the rebrand it introduced an app store, so that creators can extend the product with integrations.
History
Nathan Barry founded the company as ConvertKit, first for bloggers. In 2024 it renamed itself Kit, explaining that the change reflected an expanded mission to support creators across many fields, not only bloggers. The app store arrived with the new name.
How it differs from other platforms
Kit focuses on the individual creator instead of the large marketing team. Its design assumes one person or a small team who needs to grow a list and sell something. It competes with newsletter platforms and with general email services such as Mailchimp.
Why it matters to founders
Kit is often cited as a business built for one specific audience, creators, at a time when most email platforms targeted companies. Its rebrand is also a clear example of a company widening its market and changing its name to match.
