What Seaweed & Diamonds does
Seaweed & Diamonds, operating under the consumer brand SeaWeed Co., is a Maine-based, vertically integrated adult-use cannabis company. It operates two state-licensed dispensaries — the original South Portland location and a newer Portland Bayside storefront — and holds cannabis licenses AMS135 and AMS110. The company serves adult-use consumers, medical patients (via a referenced Direct to Patient program in Auburn), and B2B counterparties including caregivers and third-party dispensaries.
The company's core technical asset is a C1D1-certified extraction lab supporting hydrocarbon, rosin, distillation, and THCA diamond production, fed by in-house cultivation. This lab produces the house SeaWeed Co. brand as well as the premium High Seas Rosin Collection, and is also offered as a paid service to external growers, caregivers, and dispensaries, creating a B2B services revenue stream on top of captive manufacturing.
Commercially, the company makes money through three channels: (1) direct retail sales across two dispensaries plus an in-store and online loyalty program ("Mermaid") that drives repeat visits; (2) wholesale distribution of house-brand SKUs through the Apex Trading Platform into third-party Maine dispensaries; and (3) contract extraction services billed to external operators. Merchandise and e-commerce are run via Dutchie, and the company is one of Maine's earlier adult-use licensees, dating its recreational operations to the state's initial 2020 rollout. Brand positioning is supported by five consecutive Portland Press Herald Best Of Awards and a High 95 finish in a Cannabis Cup.

Seaweed & Diamonds competitors and assessment
Company assessmentBroad incumbents
- Cresco Labs: Multi-state cannabis operator with branded wholesale (e.g., High Supply, Reserve), cultivation, and retail. Comparable across SeaWeed's branded product distribution and vertically integrated processing model.
- Verano Holdings: Multi-state operator with retail (Zen Leaf), cultivation, and branded product lines. Comparable for branded product distribution and retail-led GTM comparable to SeaWeed's dispensary/wholesale mix.
- Curaleaf: Largest U.S. multi-state cannabis operator with retail, cultivation, and processing across 20+ states. Broad incumbent that frames the scale ceiling for any vertically integrated independent like SeaWeed Co.
- Green Thumb Industries: Multi-state cannabis operator with retail (Rise/Rythm), cultivation, and branded product manufacturing. Comparable across SeaWeed's cultivation, processing, and dispensary lines, though at vastly larger scale and national breadth.
- Trulieve Cannabis Corp. Vertically integrated multi-state operator with retail, cultivation, and processing concentrated initially in Florida and now expanding to other states. Useful incumbent benchmark for vertically integrated retail-led cannabis operating models.
Direct peers
- Ayr Wellness: Vertically integrated multi-state cannabis operator with retail, cultivation, and extraction/processing. Closest mid-market comparable to SeaWeed's cultivation-extraction-retail-wholesale stack.
- Columbia Care (now The Cannabist Company): Vertically integrated operator with cultivation, processing, and retail dispensaries including branded concentrates. Comparable for solventless/hydrocarbon extraction-led product strategy at multi-state scale.
- Theory Wellness: Vertically integrated Massachusetts and Maine cannabis operator with cultivation, processing, and retail dispensaries. Direct comparison point for a New England-focused vertically integrated dispensary operator in an adjacent state market.
- East Light Cannabis: A Maine cannabis cultivator/brand whose products are co-distributed alongside SeaWeed Co. in both dispensaries and wholesale. Directly comparable vertically integrated Maine operator with shared retail and wholesale exposure.
Others
- Dutchie: Cannabis e-commerce and POS platform used by SeaWeed for online ordering and merch sales. Enabling technology peer rather than a competitor; relevant for understanding SeaWeed's distribution stack.
