What Green Tank Technologies does

Green Tank Technologies Corp. (Greentank) is a Toronto-based, privately-held designer and manufacturer of vaporization hardware for the cannabis and broader inhalables industry. Founded in 2017 by brothers Dustin and Corey Koffler, the company operates as an ancillary, non-plant-touching supplier that designs, engineers, and produces empty cartridges, all-in-one disposable pens, and 510-thread batteries that are white-labeled to licensed cannabis producers, retailers, and brands worldwide; only the GT Torrch dab pen is sold directly to consumers in Canada. Greentank reports that more than 200 vape brands globally use its hardware.

The company's product portfolio spans cartridges (GT GO, GT AC all-ceramic), a deep disposables lineup (GT Palm, GT Palm Pro, GT Fuse, GT A20 MAX, GT M3, GT M8, GT A7 Mini, GT A9 Flex), and batteries (GT Surge Push, Surge Draw, Surge Twist), all built around proprietary heating technologies. Its core Ceramic Core Technology is a zero-contact, triple-baked (over 1,000°C) ceramic heating element, while the next-generation Quantum Vape platform uses a nano-fabricated semiconductor-style heating chip with a micro-engineered substrate containing more than 3,000 precision channels built from biocompatible metals. Both platforms are protected as trade secrets, and engineering is anchored in Greentank's in-house vape device lab, the first of its kind in North America, led by former Dyson engineering executive Pete Duckett. Additional moats include an industry-first CPSC-certified child-resistant cartridge (GT Spectrum CR) and a pre-loaded automated tray solution compatible with major filling vendors (ATG Pharma, Vape-Jet, Convectium, DDS, Thompson Duke).

Greentank's commercial model is B2B hardware sales through two channels: a direct sales team that handles custom-branded and large-volume orders (with 6-10 week production lead times and quote-based pricing), and a proprietary online B2B store (shop.greentanktech.com) that offers transparent wholesale-tier pricing starting at $1.35 per unit, real-time stock visibility, and next-business-day shipping for standard SKUs. The company has raised approximately USD $38.5 million across funding rounds, most recently a USD $16.5 million Series B in March 2023 led by Organigram Holdings, which also secured a Canadian exclusivity arrangement for Greentank's cannabis vape technology. The Quantum Vape platform was commercialized in European nicotine markets in 2025, with stated ambitions to extend into pharmaceutical applications, signaling a deliberate diversification of the addressable market beyond North American cannabis.

Scale indicators4 records

Recent moves6 records

Expansion highlights6 records

Emerging players

• Pulsar (Vapor Solutions): Pulsar designs and distributes vaporizers, vape cartridges, and accessories for cannabis and aromatherapy markets. Comparable product portfolio to Greentank's vape hardware line, primarily in the wholesale and retail distribution channel.
• Ooze: Ooze is a vaporizer hardware and accessories brand (batteries, pens, cartridges) with a stronger direct-to-consumer tilt but also serving the cannabis accessories retail market. Comparable product category to Greentank's lower-end offerings, though Ooze focuses more on accessories than on premium B2B white-label hardware for licensed producers.
• DaVinci (IQ/Arizer competitor segment): DaVinci manufactures premium dry-herb and concentrate vaporizers with proprietary heating technology. Comparable to Greentank in heating technology R&D and emphasis on temperature control, though DaVinci focuses on premium dry-vape consumer devices rather than B2B cannabis extract hardware.

Direct peers

• CCELL: CCELL is the dominant global cannabis vaporizer hardware manufacturer (510-thread cartridges, disposables, batteries), and is the most direct competitor to Greentank in the B2B white-label cannabis vape hardware category. Both serve licensed cannabis brands globally and compete on heating technology, customization, and scale.
• Jupiter Research (LIT): Jupiter Research is a US-based cannabis vaporizer technology company that designs and manufactures CCELL-compatible and proprietary vape hardware. Like Greentank, it focuses on B2B wholesale to licensed cannabis brands, with comparable product breadth across cartridges, disposables, and batteries.
• iKrusher: iKrusher designs and manufactures OEM/white-label cannabis vaporizer hardware (cartridges, all-in-one disposables, batteries) and competes directly with Greentank on the same B2B value proposition of customization, compliance, and bulk wholesale pricing for licensed cannabis brands.

Broad incumbents

• PAX Labs: PAX is a broad incumbent in premium cannabis and nicotine vaporization hardware, with a consumer-facing brand portfolio (PAX Era, PAX 3) and B2B partnerships. Comparable to Greentank in heating technology and compliance, but operates at significantly larger scale and with a consumer-retail focus rather than pure B2B white-label.

Regional players

• STIIIZY: STIIIZY is a major California-anchored cannabis brand with proprietary pod-based vaporizer hardware. While primarily a cannabis brand rather than a pure hardware manufacturer, it represents the vertical-integration trend that threatens Greentank's B2B white-label model in regulated US state markets.

Others

• Vape-Jet: Vape-Jet manufactures automated cannabis cartridge filling and capping machines, and is an official implementation partner of Greentank. Comparable as a complementary ecosystem participant in the cannabis vape production value chain rather than a direct competitor, sharing integration with the Pre-Loaded Tray Solution.
• Casa Verde Capital (portfolio context): Casa Verde Capital is a cannabis-focused venture capital firm and an existing Greentank investor. Relevant as a financial peer and ecosystem reference point for cannabis ancillary hardware investments rather than a direct product competitor.
