Hi, I'm Chris. Thanks for checking out ShelfSpace. I'd love to tell you why we're here.

I'm not a stranger to the cannabis industry. I've spent the last decade in the trenches, and I've got the scars to prove it. I started my vertically integrated multi-state cannabis company, Diem Cannabis, in Oregon back in 2015. I have operated on both the wholesale and retail sides of this industry, and I've been through all of our shared ups and downs.

Along the way, I've experienced incredible highs and navigated the brutal reality of market corrections. While Diem successfully continues to operate in Massachusetts today, we made the strategic decision to exit the Oregon market in 2023 — a reality that changed my perspective forever.

For years, I've watched vendors fight tooth and nail to get on dispensary shelves just to get paid on "Net 30" terms that often turn into "Net Never." I've watched retailers struggle with cash flow while perishable inventory sits collecting dust. I've seen great operators squeezed out by supply chain inefficiencies they couldn't control.

I founded ShelfSpace because I refused to keep watching my brothers and sisters in this industry struggle with a broken wholesale model. ShelfSpace is my way of fighting back.

We are here to replace our industry's broken "Net 30" standard with a system that actually works for everyone. By bringing Scan-Based Trading to cannabis, we are removing the upfront risk for retailers, solving margin compression, and guaranteeing weekly payments for vendors to solve the accounts receivable crisis and stabilize cash flow.

We started with consignment because that's where the pain is sharpest — but the AP engine we built works for every vendor relationship, with credit memo management built in. Whether you're running consignment or paying wholesale vendors, ShelfSpace gives you one platform to manage it all.

This isn't just about software — it's about creating a sustainable, transparent, and honest wholesale market.

We're here to turn "inventory graveyards" into cash flow and to ensure that the next great brand or local shop has the tools they need to survive and thrive.

Let's fix this industry together.
