About Us:
We are a small close-knit team of highly technical engineers with diverse backgrounds. Our engineering culture values lean development and data-driven practices. Together, we are building a robust, feature-rich, and easy-to-use eCommerce platform that powers online shopping for thousands of dispensaries and brands. We’re AI-enabled, not AI-driven. AI tools (Claude, AI-assisted reviews, generated plans) are part of how we work, but the engineering judgement behind every decision is human.
