Migrating your brand from one subscription platform to another sounds complicated, but it doesn’t need to be. With the right partner, migrations can be smooth and even stress-free during critical times of the year. Each brand in this case study leaned on cancel-save flows, promo testing, and, where relevant, winback automations to move fast and then optimize post-launch.
These three brands migrated to Stay AI during the busiest shopping stretch of all, Black Friday Cyber Monday. The results: seamless transitions, fast launches, and subscription programs that have soared since.
Happy Aging and Delta THC Seltzers both kicked off their migrations just before BFCM season hit and, thanks to Stay’s migration team, went live quickly and confidently. They not only grew at a fantastic rate in the months right after their migration, but they’ve also sustained that growth through another BFCM season and the following year.
Sober(ish) launched in Nov. 2025, the middle of the hectic BFCM season! They went live quickly and were ready to scale with Stay AI.
Delta THC Seltzers
Delta THC Seltzers is redefining relaxation and focus with premium THC and CBD drinks. As demand surged in 2025, the team chose Stay AI to migrate a fast-growing subscriber base right as they prepared for a major brand moment.
Even when technical hurdles popped up with one of their providers, the feedback was simple: “That’s excellent. Thank you very much.” The process stayed smooth, and within a year, Delta doubled subscribers and modernized their subscription program.
With Stay AI, they:
- Converted more first-time buyers into subscribers via smarter post-purchase flows.
- Reduced cancellations through in-flow, flexible offers, which drove an approximate 30% drop in monthly churn over five months.
- Navigated a rebrand without subscriber attrition, supported by hands-on guidance.
Delta’s story proves big moves can be executed cleanly when you have the right partner, and that operational rigor pays off quickly.
“Even with a fast-growing subscriber base and a major rebrand on the horizon, our migration to Stay AI was excellent. We doubled our subscribers within a year and cut monthly churn by roughly 30% with in-flow, flexible cancel offers. In 2026, our average churn rate improved another 27% year over year. Stay AI made big moves feel simple, and helped us sustain our rapid growth all through the year.” — Delta Team
Where are they now?
Delta entered BFCM 2025 with a subscriber base nearly twice the size it was during BFCM 2024. Even at that larger scale, they acquired 26% more new subscribers during BFCM week year over year.
Delta carried that larger subscriber base into 2026 while strengthening retention. From January through August, their average subscriber churn rate improved by 27% year over year.
Delta’s story has evolved from rapid acquisition to sustainable growth at scale. Something every brand dreams of!
Happy Aging
Happy Aging is a wellness brand focused on longevity supplements and daily health rituals. Preparing to launch right before BFCM 2024, they needed a platform that could get them live fast without weighing down their team.
The migration wrapped up quickly, in just a few weeks. The team at Stay helped to configure discounts, PDP updates, and initial promo tests before BFCM so Happy Aging could launch with meaningful experiments on day one.
“Stay AI has been core to our subscription growth from day one. We’ve seen triple-digit growth in our subscriber base, and their Cancellation Survey has helped us turn early churn into a real save rate. It’s the platform that’s grown with us.” – The Happy Aging team
Since migrating, Happy Aging’s subscription program has grown 10× compared to Black Friday the previous year. Their save rate climbed 66% in the first three months through cancel-save flows, and winback automations are already bringing subscribers back.
They also enabled promotions targeted to churn-risk customers, as well as testing different free gifts and measuring the take rate on discounted add-ons. These tests informed their new Digital Punch Card rewards – by using the product with the best take rate from their ExperienceEngine promos as the reward.
With a seamless start and compounding wins, Happy Aging shows that even the busiest season can be the smartest time to switch.
Where are they now?
Happy Aging saw strong subscriber acquisition throughout BFCM 2025 and carried that momentum into the following year. From August 2025 to August 2026, their subscriber count more than doubled, growing 108%, while subscriber churn dropped 11% year over year.
Yet again, the holiday season was more than a temporary acquisition spike for this brand. Happy Aging maintained a significantly larger subscriber base while continuing to strengthen retention throughout the whole year.
SOBER(ISH)
SOBER(ISH) is a Michigan-based marketplace for non-alcoholic, hemp-derived beverages and wellness products. The brand launched in early 2024, crossed $1M in year-one revenue, and scaled into eight figures once it turned on acquisition spend in 2025.
“We migrated to Stay AI while also switching payment processors, so we had a lot of moving pieces heading into BFCM. The Stay AI team was proactive in helping us troubleshoot and resolve issues so we could be fully live in time. We wanted more than a new subscription platform: we wanted a strategic partner and flexible tools to help us build a stronger retention program. The Stay AI team helped us get through that transition, and we’ve been happy with the platform and partnership since.” Kim Gamez, Founder, Sober(ish)
Sober(ish) came to Stay AI with two main goals: cut churn, especially between orders one and two, and drive a high-performing and flexible subscription program that could keep up with their growth trajectory.
Kickoff happened in late October 2025, and despite running both changes at once, Sober(ish) was fully live on Stay AI, tested and bug-free, before Black Friday/Cyber Monday hit. Subscribers moved over seamlessly with passwordless login which directly solved one of their most common challenges driving support tickets on a previous platform.
In the months since their migration, the team has built a genuinely connected program on Stay AI with an upgraded Customer Portal, an optimized Cancel Survey, Quick Actions for making payment updates easy, and a Digital Punch Card for celebrating subscription milestones.
When one state changed its regulations on hemp-derived THC sales, Sober(ish) used Stay AI’s advanced segmentation capabilities to cleanly wall off affected subscribers from restricted products and execute a compliant subscriber transition without disrupting the rest of the program.
That range of Stay AI tools the team has embraced is what shows up in the numbers. In 9 months, Sober(ish) cut churn by 27% and grew subscribers by 23%.
