Grenco Science

What Grenco Science does

Grenco Science is a privately held Los Angeles-based consumer hardware company founded in 2012, operating the G Pen brand in the portable vaporization category. The company designs, manufactures, and distributes a portfolio of portable vaporizers, dab pens, and electronic dab rigs (e-rigs) for dry-herb and cannabis-concentrate consumption, alongside 510-thread cartridge batteries, replacement parts, and accessories. Its technical differentiators are concentrated in the concentrate segment: five granted US patents cover the G Pen Connect torchless e-rig architecture and a patented reverse airflow system, and the Dash+ implements a hybrid convection/conduction titanium chamber with haptic feedback. The product line spans entry-level 510-thread batteries (G Pen 510 Original at $12.95; G Pen Hydout), mid-tier dry-herb vaporizers (G Pen Dash II at $49.95; Dash+ at $99.95), premium e-rigs (G Pen Connect, Roam, Micro+, Hyer), and specialty tools (G Pen Melt electric hot knife). Licensed collaborations with Cookies, Grateful Dead, Lemonnade, and Dr. Greenthumb's extend the brand into cannabis-culture product, with bundle SKUs (e.g., Ultimate Cookies Bundle at $225) and a Merch/Apparel line adjacent to the hardware business.

Grenco Science monetizes primarily through direct-to-consumer hardware sales via gpen.com, supplemented by a wholesale/Become-a-Retailer program and authorized distributors for licensed dispensaries. Geographic coverage includes the United States, Canada (ca.gpen.com), and the European Union (eu.gpen.com), with international shipping baked into the DTC stack. The go-to-motion blends paid and organic digital marketing (Instagram, YouTube, X, Facebook), email/lifecycle with a Loyalty G VIP points program and seasonal promotional codes (e.g., 710 for up to 30% off), content marketing via a buyer's guide and resource library, and retail/wholesale channel partnerships. In 2020 the company acquired Stündenglass, extending into premium glass-and-inhalation hardware, and in 2019 it closed an institutional funding round led by Serruya Private Equity and Stable Road Capital with Evolution VC Partners participating. Distribution is segmented between individual adult consumers seeking smoke-free cannabis consumption and a fragmented base of licensed retailers stocking branded vaporizer hardware; no enterprise/anchor accounts are disclosed.
