Ketone-IQ partners with world-class researchers and organizations to redefine the limits of human performance, metabolism, and longevity. They have developed a family of high-performance energy products steeped in the legacy of endurance athletics and designed to function for everyday use. Ketone-IQ helps you start strong and finish stronger.
Since the 1990s, the U.S. military has researched optimal energy sources for soldiers in active duty, finding ketones to be highly effective for enhancing endurance and cognition. While the human body produces ketones naturally, it does so in limited amounts.
Through a groundbreaking research partnership with the Defense Advanced Research Projects Agency (DARPA), Ketone-IQ observed that raising ketone levels in the body provides benefits like cognitive efficiency, decreased reaction times, and increased blood oxygen levels in physically demanding situations—and developed a method to create ketone molecules and manufacture them at scale.
Today, Ketone-IQ offers ketones in readily accessible, affordable, drinkable products and relies on email marketing to build and nurture relationships with their audience and subscription-based customers, fueling special forces soldiers, elite athletes, and anyone else who wants to improve physical performance and brain function.
When Michael Lee, Chief Marketing Officer, joined Ketone-IQ in 2017, the small marketing team handled every aspect of email campaigns. From writing and designing to coding, the team worked hard to educate a diverse audience about ketones’ benefits.
Email marketing was essential for building brand awareness, but the team struggled to stay consistent, meet goals, and keep up with the growing complexity of their customer base.
Rather than hire a larger team, Ketone-IQ sought a retention marketing partner to handle their email marketing needs while also providing strategy and creative expertise. After evaluating several companies, they chose Rejoiner for their proven results, specialized services, and expertise in design.
Ketone-IQ teamed up with Rejoiner, a partnership that has lasted over seven years and continues to evolve. Rejoiner provides not just a platform but a full-service solution, including:
The partnership isn’t just about technology. It’s also about the creativity and strategy needed to build an email and SMS marketing system that aligns with Ketone-IQ’s bold vision. Rejoiner strikes a balance between hitting the same message over and over again and creating unique content that Ketone-IQ’s audience wants to engage with.
As Lee puts it, “Rejoiner really understands design, copywriting, and the incredibly nuanced variables that go into email. We’ll stick with Rejoiner because of how their high-level expertise impacts our retention marketing.”
Over time, Ketone-IQ has adapted their marketing to different audiences, from clinical researchers, to performance athletes, and now the general public. Still, Lee says, “Every single month, with Rejoiner, we have seen improvements in performance. When you compound that over the many years we’ve worked together, it’s just such a seamless experience.”
Rejoiner has been a helpful, flexible partner as Ketone-IQ has grown. As Ketone-IQ adds new service providers, like loyalty programs, Rejoiner works with them to build new APIs, completing the integrations and getting the word out to customers quickly. Lee adds, “They are constantly thinking about our entire ecosystem of retention, and it’s a different flow of ownership than if we had to do it internally. Working with Rejoiner allows us to focus on other areas of business.”
Every single month, with Rejoiner, we have seen improvements in performance. When you compound that over the many years we’ve worked together, it’s just such a seamless experience.

Rejoiner has been instrumental in driving Ketone-IQ’s growth and building a robust subscription-based e-commerce business. With their help, Ketone-IQ has:
As a subscription-based e-commerce business, recurring revenue is crucial to Ketone-IQ’s growth, and email and SMS marketing are the key to customer retention. “We owe a lot to Rejoiner,” says Lee. “They’ve helped us grow our company by 30 times in the last three years.”
Lee credits much of this success to Rejoiner’s efficiency and deep understanding of the Ketone-IQ brand. “The amount of effort that is needed to manage Rejoiner versus the amount of impact they generate—it’s a very strong ratio,” he explains. With Rejoiner, Ketone-IQ has the freedom to focus on other areas of the business, knowing their retention marketing is in expert hands.
Rejoiner’s service and results stand out for Ketone-IQ where other software providers have struggled to deliver. “We’ve swapped out many different agencies for our organic and paid social, but we’ve never had to do that for email. Rejoiner has always just had the highest touch,” says Lee.
Rejoiner’s impact extends beyond execution. Lee has conducted significant research on subscriber retention, and the team at Rejoiner has incorporated those insights into a tailored retention strategy. This collaborative approach has saved Ketone-IQ from the complexity and expense of managing email marketing internally. Lee explains: “We needed three or four employees to understand and manage design, copywriting, engineering, split-testing, automation, analytics, and reporting. In terms of cost, Rejoiner just makes sense. It’s a no-brainer!”
We owe a lot to Rejoiner. They’ve helped us grow our company by 30 times in the last three years.

Ketone-IQ’s journey with Rejoiner is a testament to what’s possible when you have a true partner, rather than a platform alone. Throughout their partnership, Rejoiner has provided expertise, strategy, and unwavering support, helping Ketone-IQ drive growth, deepen customer relationships, and scale their business with confidence.
With a proven email marketing engine in place, Ketone-IQ is ready for their next phase of growth. Looking ahead, the brand plans to expand their email strategy further with enhanced segmentation, advanced personalization, and new campaign types to reach an even broader audience.
As Ketone-IQ’s marketing evolves, Rejoiner will remain at the heart of their retention strategy, ensuring the brand can continue empowering customers to achieve their personal bests.
