Brewing Innovation: Cometeer’s Journey to Personalized Coffee Subscriptions
Cometeer is revolutionizing the coffee industry through innovative flash-frozen coffee capsules that preserve the complex flavors and aromas of premium coffee. They’re making exceptional coffee accessible to millions through a unique subscription model that delights customers with both curated and customizable selections.
As their subscriber base expanded and business model evolved, Cometeer faced increasing complexity in their technology stack. They needed a solution that could handle sophisticated subscription logic, enable product customization, and provide a seamless customer experience—all while optimizing operations and inventory management. The company turned to Nebulab to build a scalable platform that could support their vision for the future of coffee.
With a clear focus on enhancing both customer experience and operational efficiency, Nebulab worked with Cometeer to reimagine their entire digital platform. From developing an intelligent subscription algorithm to building a custom account portal, every solution was designed to scale with Cometeer’s rapid growth while maintaining the premium experience their customers expect.
“At Cometeer, we’re on a mission to make exceptional coffee accessible to everyone. Building a technology platform that could scale with our vision was crucial for our next phase of growth.”

Crafting the perfect cup with smart algorithms.
For a subscription coffee service, delivering the right coffee to the right customer at the right time is crucial. Cometeer’s original system relied on manual configuration of box contents, which became increasingly complex to manage as their product line expanded. They needed a solution that could automatically match customers with coffees they would love while optimizing inventory management.
Nebulab developed Skewer, a sophisticated algorithm that dynamically maps individual coffee sleeves to customer preferences. The system moved away from static box configurations to a flexible, sleeve-based approach that considers multiple factors including customer order history, ratings, and inventory levels. The algorithm can be fine-tuned through configurable parameters and even supports A/B testing of new products, making it a powerful tool for both customer satisfaction and growth.
The impact was immediate and measurable. With Skewer, operations teams no longer need to manually configure boxes, and customers receive more personalized selections. Furthermore, the system extends beyond the initial subscription, powering smart recommendations when products are out of stock and enabling proactive customer communication at all stages of the customer journey.
Empowering choice with BYOB.
Customer feedback consistently showed a desire for more control over coffee selections and the ability to customize their subscription boxes. Additionally, Cometeer saw an opportunity to introduce premium offerings at different price points, moving beyond their classic one-size-fits-all subscription model.
The team developed a modular Build Your Own Box system that gives customers unprecedented control over their coffee selections while maintaining the flexibility to accommodate special product drops and promotional campaigns. The solution includes a dynamic interface where customers can customize their selections, with Cometeer having full control over section configuration and promotional content placement.
The results were impressive: average order value increased by 10%, representing a significant boost in revenue. Moreover, customer engagement with customization features grew dramatically.
Reimagining the customer account experience.
Cometeer’s reliance on Shopify’s and Recharge’s native account management systems was creating friction in the customer experience and limiting their ability to implement custom features. They needed a solution that would give them more control over the customer journey while improving performance and user experience.
Nebulab built a custom account portal from the ground up using Rails and modern web technologies. The new system provides seamless integration with both Shopify and Recharge APIs, enables aggressive client-side caching for improved performance, and includes features like coffee ratings and preference management.
The new portal significantly improved the customer experience with faster load times, easier access to actions such as the “Send Now” feature, and the ability for Cometeer’s engineering team to iterate more quickly—leading to faster rollout of new features.
“Nebulab’s technical expertise and understanding of e-commerce helped us build a robust, scalable platform that enhances both our operational efficiency and customer experience. Their ability to tackle complex challenges while keeping the solution elegant has been invaluable.”
