# How Sudowrite Used Churnkey to Retain Thousands of Customers and Boost Revenue by Over Six Figures

## Company

Sudowrite is an AI writing partner for fiction authors — "the non-judgmental, always-there-to-read-one-more-draft, never-runs-out-of-ideas-even-at-3am AI writing partner you always wanted." Co-founded in 2020 by Amit Gupta and James Yu, Sudowrite has been called "scary good" by author Hugh Howey, a "salvation" by Stephen Marche in The New Yorker, and has been covered by The Atlantic, WIRED, and The New York Times.

## The Challenge

The "scary good" product grew its customer base fast thanks to impressive coverage and positive reviews. That made onboarding the influx of customers, learning from their needs, and shipping product improvements a monumental task. On top of that, rapid growth brought cancellations and failed payments, making retention an initiative that someone needed to own.

> "A small team demands sharp focus. Every minute we spend on churn reduction or failed payment recovery — which both contribute to our bottom line — is a minute taken from product development and growth — our top line. We didn't have the bandwidth to do both. But I also knew I couldn't ignore it."
> — Amit Gupta, Co-founder of Sudowrite

## The Solution

Amit used Churnkey's cancel flows to A/B test different strategies. In one version, he created unique cancellation experiences that pointed certain customer segments back to the Sudowrite Slack community to get help — which also reinforced the community's value and uniqueness. Meanwhile, Churnkey intelligently recovered card payment failures in the background.

Thanks to feedback from the community, it became clear that some authors weren't always realizing the full benefit of the product. Writers that joined the community to learn from each other were the most successful, so directing at-risk users there was a natural retention lever.

> "Churn reduction is nuanced. We want to help customers who need a hand getting the most out of Sudowrite, while letting those who need to pause or cancel their account do so easily. Churnkey allows us to help our customers while giving me the headspace to focus on product, community, and growth."
> — Amit Gupta, Co-founder of Sudowrite

## The Results

- **Six figures in revenue boost** in less than a year across voluntary and involuntary churn channels
- **Thousands of customers retained** through personalized cancel flows
- **Hours of team time saved** — redirected from churn management to product innovation

For Sudowrite, Churnkey helped them break their cycle of churn and provide an overwhelmingly positive ROI. Gupta, along with his entire team, gained hours back in their days — hours they could now use to innovate and push their product further.

> "We help experienced authors beat their writing goals and create richer worlds, and help first-time authors tell the stories they've always wanted to tell. With Churnkey's help, we can do that even better."
> — Amit Gupta, Co-founder of Sudowrite
