Churnkey serves subscription businesses ranging from startups to enterprise companies across SaaS, media, creator tools, education, construction technology, and more. Below are summaries of published case studies demonstrating measurable retention and revenue results, followed by additional customer testimonials. --- ## Superhuman **Company**: Superhuman — the email platform known for speed, efficiency, and relentless customer focus. **Challenge**: Turning team seat downgrades into an opportunity for growth. When teams reduced the number of members on their plan, Superhuman needed a way to retain customers and minimize revenue loss. **Solution**: Churnkey Cancel Flows transformed these moments of churn into opportunities for retention, feedback, and price optimization. **Results**: Protected seven figures of revenue and saved over 3,000 customers. > "Churnkey helped us save more customers and learn what they actually needed from us. It changed how we approach retention entirely." > — Ben Ophoven-Baldwin, Senior Product Manager at Superhuman [Read the full case study](https://churnkey.co/case-studies/superhuman) | [Agent-readable version](/case-studies/superhuman/index.html.md) --- ## VEED **Company**: VEED — online video editing platform launched in 2018. Within four years it acquired tens of thousands of subscribers, generated over $7 million in annual revenue, and raised $35 million from Sequoia. TechRadar called VEED "an excellent selection of well-designed tools." **Challenge**: Alongside subscriber growth, churn was quickly becoming an issue, and Principal Product Manager John Hamilton had to figure out how to tackle it. **Solution**: Churnkey Cancel Flows and Payment Recovery. **Results**: Recovered 14,000 failed payments and retained 5,000 cancelling customers. > "Working with Churnkey has been so crucial for VEED as a product. The aggregated data from our customers opened the doors for us to discover new features customers wanted but still needed improvement." > — John Hamilton, Principal Product Manager at VEED [Read the full case study](https://churnkey.co/case-studies/veed) | [Agent-readable version](/case-studies/veed/index.html.md) --- ## Buildertrend **Company**: Buildertrend — all-in-one construction management platform. Over one million customers served, over two million projects tracked, and a presence in over 100 countries. **Challenge**: As the product's surface area grew, customers moving through a homegrown cancellation process produced feedback that lacked data uniformity, overwhelming the support team. The team needed actionable data analysis to make better product decisions. **Solution**: Churnkey Cancel Flows with structured feedback collection and [Feedback AI](/feature/customer-insights-ai.html.md) for data analysis. **Results**: Six figures in increased revenue within five months, plus a new product feedback pipeline. > "The Churnkey team has built and delivered on every promise made. This will be a complete game changer for our business. 10/10 recommend." > — Charley Burtwistle, Senior Director of Core Subscription at Buildertrend [Read the full case study](https://churnkey.co/case-studies/buildertrend) | [Agent-readable version](/case-studies/buildertrend/index.html.md) --- ## Sudowrite **Company**: Sudowrite — AI writing partner for fiction authors, co-founded in 2020 by Amit Gupta and James Yu. Called "scary good" by author Hugh Howey and a "salvation" by Stephen Marche (The New Yorker), and covered by The Atlantic, WIRED, and The New York Times. **Challenge**: Rapid growth brought cancellations and failed payments, making retention an initiative someone needed to own. **Solution**: Churnkey Cancel Flows and Payment Recovery. **Results**: Retained thousands of customers and boosted revenue by over six figures. > "Churn reduction is nuanced...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 [Read the full case study](https://churnkey.co/case-studies/sudowrite) | [Agent-readable version](/case-studies/sudowrite/index.html.md) --- ## ShotDeck **Company**: ShotDeck — the largest collection of fully searchable high-definition movie images in the world. Users range from film students to the Russo brothers, directors of Avengers: Endgame. **Challenge**: Rapid growth meant churn was starting to become a problem, and the cancellation flow had become a black box with no reliable way to capture cancellation insights. **Solution**: Churnkey became the backbone of ShotDeck's retention efforts, with structured cancellation insights turning the black box into something visible and workable. **Results**: Gained visibility into churn drivers. Discovered that less than 1% of cancellations were leaving for competitors, and that most cancellations came from budget or usage reasons, providing clear, actionable focus areas. > "What really helped was finally seeing why people were churning. Realizing that less than 1% were leaving for competitors, and that most cancellations came from budget or usage reasons gave us clarity. Those are things we can actually work on." > — Ethan Young, ShotDeck Co-Founder and COO [Read the full case study](https://churnkey.co/case-studies/shotdeck) | [Agent-readable version](/case-studies/shotdeck/index.html.md) --- ## OneUp **Company**: OneUp — social media scheduling tool. **Challenge**: An in-house email campaign asking churned customers why they cancelled had very low response rates and a low return on investment. **Solution**: Churnkey's cancellation and customer insights survey at the moment of cancellation. Because responses can be required, every cancellation becomes its own story, not just a vague data point. **Results**: Cut churn by 20%. Feedback revealed that an outdated user interface was causing trialing customers to cancel, so OneUp reprioritized a UI update it would otherwise have kept putting off. > "Honestly, Churnkey is easily worth the cost for its cancellation feedback alone. We've been able to gain so much insight into why users want to cancel so we can add features or fix issues." > — Davis Baer, CEO at OneUp --- ## Zubtitle **Company**: Zubtitle — video captioning tool for creators making content for social media. **Challenge**: Creators batch their video work, so users often needed to pause between sessions. Zubtitle's custom cancellation flow was susceptible to API changes and produced inconsistent data that was hard to report on. **Solution**: Churnkey Cancel Flows with subscription pauses, discounts, "hidden" plans, and funnels into customer support teams. **Results**: A 28% drop in churn and a 26% LTV extension in only two months. Churn fell from ~10% to 7.2%, and almost a quarter of customers who would have cancelled stayed on. > "Being a startup founder means knowing what to delegate and when. Churnkey automatically supports our customers when their payments fail. Better yet, it pays for itself." > — Jay McAliley, Co-founder of Zubtitle --- ## More Customer Testimonials > "Churnkey has been a lifesaver for improving customer retention at Relume.
