Supplier sourcing & vetting
We find factory-direct partners, run sample rounds, audit compliance and capacity, then negotiate terms that protect your margin from day one.
Global B2B Sourcing & Brand Building
We are the supply chain behind breakout brands.
Granite Harbor finds the factories, vets the suppliers, and ships the products that turn a good idea into a category-leading ecommerce brand — so operators can build instead of chase.

What we do
Everything between a product idea and a profitable order.
We operate as the off-balance-sheet supply team for ecommerce founders — sourcing, branding, and logistics under one roof.
Private label development
Turn a generic SKU into an ownable, branded product — packaging, inserts, and a story customers remember.

How it works
A clear path from brief to bestseller.
Four stages, one accountable team. You always know what's happening to your product and your money.
01
Discovery & sourcing brief
We start with your category, margin targets, and timeline, then map the global supplier landscape that fits them.
02
Vetting, samples & audit
Shortlisted factories are sampled and audited for quality, capacity, and compliance — you approve before a cent moves.
03
Branding & production
We build packaging and product identity, lock pricing, and manage the production run with QC at every checkpoint.
04
Fulfillment & scale
Inventory lands in our network and ships to your customers, with reorders and freight handled as you grow.

Granite Harbor stays deliberately behind the scenes — we don't run social accounts of our own. The brands above did the growing in public; our work is the supply chain that let them. Founder details and references are shared directly on request.
Why Granite Harbor
Operators first. Vendors never.
Granite Harbor is a new company, but not an inexperienced one. It was founded by operators who spent the better part of a decade inside ecommerce — sourcing overseas, launching private-label products, and learning where supply chains quietly break.
We started Granite Harbor to do that work for other founders: be the team that sources honestly, audits rigorously, and ships reliably — without the markups and mystery of a typical trading middleman.
No fluff, no resold catalogs, no inflated MOQs. Just a supply chain you can actually build a brand on.
Audited, not assumed
Every supplier is sampled and verified before we recommend them. We stake our name on quality.
Margin-obsessed
We negotiate factory-direct and protect your COGS, because a brand without margin isn't a business.
One accountable team
Sourcing, branding, and logistics under one roof means no finger-pointing when something needs to move.
Built to scale with you
From first sample run to repeat freight, the system grows as your order volume does.
