Greentank co-founders discuss innovation and growth in cannabis hardware industry.

Greentank co-founders discuss innovation and growth in cannabis hardware industry. Key takeaways. * Greentank, co-founded by Corey and Dustin Koffler in 2016, focuses on innovative vaping technology for cannabis and nicotine products. * The company has developed proprietary quantum chip technology to enhance safety and flavor in vaping while reducing harmful emissions. * Greentank raised over $70 million through strategic funding to emphasize R&D and technology differentiation for growth. * Building strong relationships has been key for Greentank in navigating industry challenges, including regulatory scrutiny. * The founders encourage perseverance, relationship-building, and continuous innovation for aspiring entrepreneurs. In an in-depth interview on the Beard Bros Media Network, Corey and Dustin Koffler, co-founders of Greentank, shared their journey from humble beginnings in Toronto to becoming leaders in cannabis hardware technology. Their story highlights innovation, strategic investment, and the importance of perseverance in a rapidly evolving industry. Founded in 2016, Greentank has established itself as a pioneering company focused on developing safer, higher-quality heating technology for vaping cannabis, nicotine, and wellness products. With a team of approximately 130 employees across Toronto, Shenzhen, and the UK, the company has expanded its reach into North American and European markets. From Toronto roots to global innovation. Growing up together in Toronto, the brothers' collaboration was rooted in a shared passion for improving the vaping experience. Dustin's early work involved selling non-nicotine e-cigarettes, which laid the groundwork for their eventual focus on hardware. Dustin recounted a pivotal moment at a wedding in Aspen, Colorado, where he observed the vaping habits of attendees - predominantly baby boomers - using early-generation devices that failed to deliver a satisfying experience. This moment sparked the idea that existing technology could be improved. "I realized that the technology being used was nascent and that I could make it better," Dustin explained. "That epiphany led us to develop hardware specifically designed for cannabis oils, offering a cleaner, safer, and better-tasting experience." Innovating with Technology Greentank's technological advancements include the development of their proprietary quantum chip technology - an innovation that enhances safety and flavor while reducing harmful emissions. Their focus on safety and quality has attracted numerous industry partners, regulators, and investors. "Safety is our top priority," said Corey. "We use biocompatible materials and microfluidics to vaporize oils more efficiently and safely. Our technology produces a cleaner aerosol with fewer harmful byproducts - 99% cleaner than many approved market products." Strategic growth and investment. The company's growth has been fueled by strategic funding rounds, raising over $70 million to date. Early investments focused on R&D, with subsequent rounds emphasizing technological differentiation and vertical expansion. Green Tank's ability to secure funding from a selective group of investors - ranging from manufacturing experts to cannabis and nicotine industry leaders - has enabled continuous innovation. "Having a clear plan on how to use funds was crucial," said Dustin. "We invested heavily in R&D and manufacturing, especially in our proprietary chip technology, which is manufactured entirely in-house in Shenzhen." Navigating industry challenges. Throughout the interview, the brothers emphasized the importance of building strong relationships - both within their team and with partners. Their close-knit dynamic, built on mutual trust and complementary skills, has been critical to navigating industry challenges, including regulatory scrutiny and market volatility. "Our culture of perseverance and treating people well has been key," Corey remarked. "Starting a business is a roller coaster, but staying committed and focused on your vision makes all the difference." Looking ahead. Greentank continues to push the boundaries of vaping technology, with ongoing projects to further refine heat control and aerosolization. Dustin shared excitement about their next-generation products, which promise even greater safety and performance. "Our goal is to revolutionize how people consume oils," he said. "We're already working on innovations that will take our technology even further." Final thoughts. The Koffler brothers' journey underscores the importance of innovation, strategic planning, and resilience in building a successful industry-leading company. Their advice to aspiring entrepreneurs: pursue your passions with perseverance, build strong relationships, and never stop innovating.

Greentank secures USD $20 million strategic investment.

Greentank secures USD $20 million strategic investment. July 31, 2026 TORONTO - Greentank Innovations Corp., a global pioneer in advanced vaporization hardware and material science, closed a USD$20 million strategic equity investment from AIR Global PLC (AIR). Founded in 1999 and headquartered in Dubai, AIR is a global consumer brands and innovation company with a presence in more than 90 markets worldwide. The investment, made at a pre-money valuation of approximately USD$170 million, expands upon the strategic partnership established between Greentank and AIR in 2023. As part of the agreement, AIR secures a warrant with the option to increase its equity stake by up to 20% over the next 24 months at a valuation of USD$250 million. The transaction includes enhanced commercial terms, long-term supply commitments, access to next-generation technologies, and board representation. The capital will directly accelerate Greentank's growth trajectory, enabling the company to scale its fully owned and operated, semi-automated chip manufacturing facilities, advance its deep-tech research-and-development pipeline, and expand the global deployment of its proprietary Quantum Chip(TM) atomization platform. Pioneering the next generation of inhalation science. Greentank's flagship Quantum Chip(TM) platform represents a shift away from legacy ceramic and wire-coil heating technologies. Engineered at a molecular level, the chip technology delivers precise thermal regulation, optimized aerosol mass, and taste consistency across a variety of liquid formulations. The strategic investment coincides with preliminary scientific validation of Greentank's technology. In an independent pilot study conducted by McKinney Specialty Labs LLC, aerosol generated by AIR's Crown Switch(TM) vape, a device powered by Greentank's Quantum Chip(TM) platform, demonstrated significantly reduced levels of harmful and potentially harmful constituents (HPHCs) compared to published data on FDA-authorized vape devices and traditional combustible cigarettes. Key study highlights for Crown Switch aerosol included: * Carbon monoxide: Below detection limits across all tested formulations and power settings. * Heavy metals and volatiles: Arsenic, cadmium, chromium, lead, nickel, benzene, and 1,3-butadiene were predominantly non-detectable or below limits of quantification. * HPHC reductions: Significantly reduced levels of carbonyls (including acetaldehyde and formaldehyde) compared to FDA-authorized benchmark vaping devices. "This capital injection and expanded strategic partnership with AIR validate both the commercial viability and scientific foundation of our Quantum Chip(TM) platform," said Greentank co-founder and Chief Executive Officer Corey Koffler. "When we developed our microchip heating technology, our goal was to redefine what's possible in vaporization, delivering unprecedented aerosol consistency and performance while driving reduced-risk innovations across global markets. This funding enables us to rapidly scale our semi-automated manufacturing, broaden our patent portfolio, and solidify Greentank's position as the hardware engine powering the future of the inhalation industry." Fueling infrastructure, R&D, and global commercial scale. With a robust patent portfolio dating back to 2014, Greentank has built a significant presence across legal cannabis, nicotine, and wellness vaporization hardware categories. The funding will focus on three core strategic pillars: * Manufacturing automation and scale: Expanding capacity at Greentank's specialized chip manufacturing facility to meet growing volume demands from tier-one global brands. * Material science and intellectual property acceleration: Advancing proprietary microchip heating designs, micro-fluidic controls, and next-generation substrate formulations. * Global market footprint: Strengthening supply agreements and commercialization pathways across North America, Europe, and emerging global markets.

Marketing spotlight: Jennifer Smart, Greentank.

Marketing spotlight: Jennifer Smart, Greentank. In heavily regulated industries, most of the marketing playbook is off limits. That's exactly the challenge Jennifer Smart faced when she took the marketing manager role at Greentank, a cannabis hardware company headquartered in Toronto, Ontario - where advertising restrictions rule out many of the channels marketers typically rely on. Now five years into the role, Smart has learned to make the most of what she can use. She leaned into thought leadership and brand credibility rather than direct product promotion, turning a constraint into a competitive advantage. In this conversation with Encore360, Smart shares her path into cannabis marketing and how she competes in a volatile industry without the full marketing toolkit. Encore360: What led you to marketing in the cannabis space specifically? Jennifer Smart: I actually started in PR - that's where my advanced diploma is from. I did an internship that was more marketing focused and I quickly realized I liked that more. What really confirmed it for me was when I ended up doing a PR internship and realized that career path wasn't for me. I've always been a creative person, so I really enjoy being able to combine creativity with strategy. Figuring out what motivates people, what motivates buyers, understanding different audiences, and finding the best way to communicate a product or an idea. I was actually headhunted for this role, but at the time I was looking for an opportunity in the marketing space. My previous role was heavily focused on tradeshows, and only a little bit on the marketing side. Greentank actually reached out to me, and this was a completely new space for me. Since I wasn't familiar with Greentank, I spent some time learning about the company. That's when I realized it wasn't a cannabis company in the traditional sense - it was a B2B technology company developing innovative hardware for the cannabis industry. I found that really interesting. I've always been fascinated by technology. Whether it's PC gaming, console gaming, or the latest products from Apple, I'm always interested in seeing what's new and how technology continues to evolve. That made Greentank feel like a natural fit. Even though at that point my background had been primarily in the B2B fashion and beauty industry, I thought why not take a chance and see? And I'm happy I did. You've held a marketing/PR position at several different companies in different industries. How do you tailor your approach to meet each company's goals? When I was with a B2B fashion accessories company, I was a tradeshow marketing coordinator. My main focus was building brand awareness specifically through tradeshows. Encore360 did a lot more shows than Encore360 do at Greentank - I think at one point Encore360 were doing 25 shows and it was just me managing all of that. Building that brand awareness was the main priority, and also showcasing the products in a very visual, trend-driven way. At Greentank, while tradeshows are still a big part of my role, I've transitioned more on the strategy side of things. Encore360 is marketing highly technical products in a heavily regulated industry. There's a much stronger emphasis on education, thought leadership, and helping customers understand the value behind its technology. But in both roles I started by understanding who its audience was and what the business was trying to achieve. From there, adapting the messaging, the content, and the marketing channels to support those goals. I also balance creativity with data, continuously measuring what's working, making adjustments where needed, and refining its approach over time. So even though they're very different industries, I think the core principle always remains the same. Understanding your audience, aligning the marketing strategy with the company's objectives, and creating campaigns that generally add value. And that doesn't mean always focusing the content on product placement or new launches. You've got to mix it up. Especially in a B2B industry, I think one of the most important things you can do is educate your audience and share valuable industry expertise. Now, you've been with Greentank for about five years. Can you speak to how the company's marketing strategy has changed throughout your time there? When I first joined Greentank in August 2021, Encore360 were largely focused on building brand awareness. My primary responsibility was managing its tradeshows. Over the past five years, both the company and its marketing strategy have matured significantly. Today, its approach is more focused on building long-term credibility and partnerships while positioning Greentank as a leader in cannabis hardware technology. Because of the restrictions around advertising, Encore360 has leaned heavily into educational content, PR, email marketing, client appreciation events, and tradeshows. Encore360 has also become a lot more collaborative across departments, working very closely with sales and getting their insights. They're boots on the ground, always knowing what's going on and what changes they're seeing in the industry. Encore360 tweak its marketing strategy based on the feedback that they share with Encore360. Its product teams also play an important role in ensuring its messaging aligns with what's coming through its product pipeline. Overall, Encore360 has become more strategic, more data-driven, and more focused on creating long-term value rather than simply promoting products. The cannabis industry has had its fair share of ups and downs. How have you navigated those challenges as a marketer? Being adaptable, for sure. The cannabis industry changes very quickly, whether it's evolving regulations, market shifts, or changes in customer demand. The marketing behind it has to evolve just as quickly. Although traditional advertising channels aren't available to Encore360, Encore360 has had to be creative in how Encore360 connect with its audience. Encore360 focus heavily on educational content, technical expertise, industry events, and building strong relationships with its customers. Encore360 also invest in paid advertising where it makes sense. That's something that works really well for lead generation - advertising through trusted cannabis industry publications that allow Encore360 to reach its target audience in a compliant way. These challenges have ultimately made Encore360 more resourceful as marketers and reinforce the importance of staying close to both customers and the industry as a whole. What excites you most about your role at Greentank and the work you do with the company? No two days are exactly the same. I have the opportunity to work across so many different areas of marketing, whether it's planning tradeshows, creating content, supporting product launches, managing email campaigns, or collaborating with its sales team and stakeholders. I really enjoy that variety because it keeps me challenged, constantly learning, and keeps things interesting. I also love working with such a great and innovative team - the culture here is the best. Greentank is always pushing the boundaries of technology and innovation, and it's really rewarding to help communicate that story. Where do you see the future of cannabis marketing in five years from now? I think cannabis marketing will continue to become more sophisticated as the industry matures. Education and authenticity are going to become even more important, and the brands that build trust through transparency will be the ones that stand out. I also think AI will become a powerful tool for cannabis marketers, especially as brands look for smarter ways to personalize customer experiences while navigating a highly regulated industry. As AI becomes integrated into virtually every marketing platform, it will help teams work more efficiently, and spend more time focusing on strategy and creativity instead of repetitive tasks. As regulations continue to evolve, hopefully there will be more opportunities to leverage digital marketing channels while still remaining compliant. Maybe in the future Encore360'll be able to do digital ads, which would be really exciting. Regardless of how the marketing landscape changes, I think the companies that succeed will be the ones that focus on innovation, delivering value to customers, and building long-term relationships.
