Abraham Lincoln, Peter Drucker, and Alan Kay all have been credited with coining the phrase “the best way to predict the future is to create it.” Brothers Corey and Dustin Koffler founded Greentank Technologies on the concept.
Greentank develops and manufactures cutting-edge vaporizer hardware. From its foundation in 2016, the company has focused on engineering products optimized for cannabis extracts.
At the time, “the hardware just wasn’t built for cannabis,” said Chief Executive Officer Corey Koffler. “The devices were originally designed for low-viscosity e-liquids, and consumers were struggling with performance issues when using much thicker, more complex cannabis extracts.”
Their goal “wasn’t just about [improving] functionality or form factor,” he added. “It was about elevating the entire experience. We committed to delivering unmatched performance, reliability, and safety.”
Today, Greentank employs more than 100 people across North America and other regions. The company’s team includes in-house engineers, designers, scientists, and product specialists, all of whom Koffler said are passionate about Greentank’s mission and helping the company maintain end-to-end control over product development.
“Our device lab, located at our Toronto headquarters, is where innovation meets precision,” Koffler said. “Equipped with state-of-the-art equipment, our expert team — including material scientists, engineers, product designers, and testing specialists — conducts meticulous ‘oil-to-coil’ testing to optimize performance and analyze safety metrics for every device we bring to market. But what truly sets us apart is our ability to fine-tune our products with real cannabis extracts.”
Greentank is the only vape technology company that has been issued a federal research license by Health Canada.
“With our research license, we can simulate cannabis oil profiles to conduct rapid and efficient optimization testing,” Koffler said. “This level of precision ensures that when our products hit shelves, they do so with unmatched reliability and performance. Our license allows us to work hands-on with our brand partners, testing a wide range of cannabis extract formulations to ensure the highest levels of performance, consistency, and safety. For us, this isn’t just a regulatory advantage—it’s a core part of how we push the boundaries of vape technology, refining and evolving our products to meet the ever-growing demands of the industry.”
Greentank’s Quantum VapeTM is the most recent example of what combining an in-house lab with a federal research license can produce. Although vaping cannabis may be healthier than smoking, concerns about risks like inhaling heavy metals continue to plague traditional vaping hardware. Standard vapes rely on ceramic coils for heating. The core can corrode or degrade over time — especially at the higher temperatures required to vaporize thick cannabis oils — allowing particles to leach into and contaminate the vaping liquid. Quantum Vape uses a biocompatible heating element called Quantum ChipTM technology, which instantly vaporizes liquid without allowing it to contact any metal components. As a bonus, Quantum Vape’s ColdstreamTM technology produces vapor that is up to 52-percent colder than other leading vaporizers.
“For the past four years, our team has been rethinking the very engine of vaporizers,” Koffler explained. “We moved away from ceramics and their outdated absorption-based atomization, instead developing Quantum Chip technology — a game-changing system that uses microfluidics and capillary action. Think of an ultra-modern pump that seamlessly draws cannabis oil through the chip to a heating layer where it is converted into vapor. The impact has been monumental.”
Although Quantum Vape represents a bold new future, Greentank’s innovation doesn’t stop there. The company also produces traditional cartridges, disposable vapes, and batteries. All receive the same attention to detail to ensure reliability and high performance, Koffler said.
“Every single device that leaves our facility undergoes rigorous quality-control testing — triple-checked for consistency and performance,” he said. “Our manufacturing standards are second to none, ensuring that when consumers pick up a Greentank device, they’re getting an experience they can trust every single time.”
Any brand in the cannabis industry can customize their own Greentank vape. To date, the company has helped more than 300 brands in the United States and Canada launch vaporizer products.
“We collaborate closely with our brand partners to develop one-of-a-kind vape products that command attention on dispensary shelves,” Koffler said. “Whether it’s bold aesthetics, innovative features, or a unique form factor, our team brings concepts to life with a wide range of customization capabilities. For brands that want to push boundaries even further, our in-house design and engineering teams can create a completely custom vaporizer from the ground up.”
Although the Greentank team harnesses complex science to power its products, the company is grounded in elegantly simple concepts.“At the end of the day, we’re focused on three things: quality, safety, and user satisfaction,” Koffler said. “We work backward from these goals, striving to innovate the vape hardware industry one product at a time. We stand behind everything we produce because we believe in what we breathe, and we know that superior products will always win.”
