What we do
Services
We build and operate technology for every layer of a cannabis business — from the customer-facing point of sale to the back-office pipelines that keep regulators happy.
POS & Retail Systems
Point-of-sale, inventory, and checkout systems tuned for regulated retail, from integrations to custom builds.
Custom Software
Internal tools, mobile apps, and integrations that your off-the-shelf stack cannot handle.
Web & Search
Fast, compliant websites and content systems that rank and convert in a restricted ad market.
Data & Analytics
Dashboards, METRC pipelines, and reporting layers that turn compliance data into operational insight.
Integrations
METRC, payment processors, delivery platforms, and ERP connections — built to stay current as APIs shift.
Fractional CTO
Embedded technical leadership for operators scaling past spreadsheets and whiteboards.
Free Tool
Cannabis Website Audit
Run a free, automated scan of your cannabis, CBD, or hemp website. We check SEO, speed, compliance signals, e-commerce readiness, and AI search visibility — then send you a scored report with exactly what to fix. Built for dispensaries, brands, cultivators, processors, delivery, and MSOs.

Industries
Cannabis is not a single market. Dispensaries, cultivators, processors, delivery operators, multi-state operators, and consumer brands each face distinct technical and regulatory challenges.

How we work
Process
We do not believe in black-box development. Every engagement follows a four-phase process designed to surface problems early, keep stakeholders informed, and deliver working software on a predictable schedule.
Discovery
We map your current stack, compliance posture, and bottlenecks in a single structured session. No generic pitch deck — just a clear picture of what is working and what is not.
Systems Design
Architecture, data flow, and integration plan tailored to your state regulations and operational model. We document every API connection before we write production code.
Build
Sprints with working demos every two weeks. You see progress, not promises. We deploy to staging early so your team can test real workflows.
Launch & Support
Production deploy, staff training, and a support window that actually responds. We monitor error logs and performance metrics for the first 30 days.
