Shake Shack does not run the kind of supplier-diversity program you find at a JPMorgan or a Lockheed. There is no public "supplier inclusion" microsite, no Tier-2 reporting page, no NMSDC partnership announcement. What it does have is a real, narrow front door for vendors and a quieter one for food brands that want to land on the menu. If you sell anything to a roughly 550-location fast-casual chain (and Shake Shack runs in that range across company-operated and licensed Shacks), this is how the machine actually takes you in.
What Shake Shack buysTwo very different spend categories, two different paths.
The first is food and beverage: beef, potato buns, cheese, custard base, produce, the proprietary stuff that ends up in a burger. Shake Shack is famous for sourcing 100% all-natural Angus beef with no hormones or antibiotics, cheese sauce, and a specific Martin's-style potato roll. If you're a food or ingredient brand, this is the path where a single win can be large and durable, and where the bar is highest.
The second is non-food and beverage: packaging, cleaning supplies, smallwares, uniforms, equipment, construction and build-out services, facilities, technology, professional services, marketing. This is where most diverse suppliers realistically compete, because the categories are broad and the incumbents are not always locked in.
Knowing which bucket you're in matters, because the registration door is different for each.
How registration actually worksHere is the part most "how to sell to Shake Shack" articles get wrong: there is no single open vendor application that lands you on an approved-supplier list. Shake Shack uses a custom supplier portal built around its procure-to-pay system, not an off-the-shelf Ariba or Coupa marketplace that you can self-register into from the outside. Shake Shack rebuilt its procurement and supplier management as a self-service portal covering the full purchase-order-to-payment lifecycle.
The portal is for suppliers Shake Shack is already doing business with. Inside it, you view purchase orders, check invoice and payment status, and maintain your master data: contacts, addresses, and the bank account used for ACH payments. You don't get into it by filling out a public form. You get in by emailing procurement@shakeshack.com with your supplier name and address, your primary contact name and email, and the subject line "Supplier Portal Access Request." That same address is your line to Accounts Payable for portal questions.
So the portal is the back half of the relationship. The front half (getting Shake Shack to want you in the first place) runs on two channels.
The ingredient and product door (food brands)
Shake Shack publishes a short form at shakeshack.com/become-a-supplier for people who want to share an ingredient or product. You submit the idea; if it's a fit, the team follows up for samples and more detail. It's deliberately low-friction and low-commitment on their end. Treat it as a pitch, not an application. A regional hot sauce, a better bun, a seasonal produce item that fits a limited-time offer (Shake Shack runs a lot of LTOs) has a real shot here if the product is genuinely distinctive and you can talk credibly about supply at scale.
The compliance door (non-food vendors)
If you're a non-food/beverage vendor, read Shake Shack's Non-Food/Beverage Supplier Compliance Guidelines before you pitch anyone. It's a published PDF in the purchasing section of their site (last revised December 2019). It spells out invoicing, routing, packaging, and documentation expectations. Showing up already aligned with it signals you've done the homework, and it shortens the back-and-forth once a buyer is interested.
How to get noticed (and invited)Because there's no open marketplace, getting in is a sales motion, not a form-submission motion.
- Lead with category fit and a real proof point. Shake Shack's buyers care about quality sourcing and operational reliability across a growing footprint. "We supply three comparable national fast-casual brands and can serve your Northeast and Southeast distribution today" beats any diversity pitch on its own.
- Have a capability statement ready. One page: what you supply, where you operate, your certifications, your largest comparable accounts, and a named contact. If you don't have one, our capability statement builder gets you a clean version fast.
- Use the right door for your category. Food brands go through the ingredient form. Non-food vendors align to the compliance guidelines and then reach procurement directly.
- Be specific about scale. A 550-Shack chain can't onboard a supplier who can serve five locations. Say what volume and geography you can actually cover.
Be honest with yourself about this: Shake Shack has not published a supplier-diversity or supplier-inclusion program, a diverse-spend target, or a Tier-2 program that we could verify as of mid-2026. That doesn't make your MBE, WBE, SDVOSB, or LGBTBE certification worthless here. It changes how you use it.
A certification from a body like the National Minority Supplier Development Council is third-party proof that your ownership and your business are what you say they are, and it's increasingly a checkbox in procurement intake even at companies without a loud public program. If you're weighing whether to certify at all, our NMSDC certification guide walks through who qualifies and what the process costs. Lead with capability, attach the certification as a credential, and don't expect it to open a door that capability didn't already open.
If you're pursuing multiple certifications to be ready for buyers across food service, retail, and government, CertifyAll handles the paperwork for several federal and state certifications from one set of documents, so you're not filing the same forms five times.
The Tier-2 side doorHere's the play most suppliers miss. Even without a published Tier-2 program, Shake Shack buys through prime suppliers and distributors (broadline foodservice distributors, packaging consolidators, facilities and construction GCs). Many of those primes do run formal second-tier diversity programs because their own large customers require them to report diverse spend.
So instead of waiting for Shake Shack to invite you directly, you can become a subcontractor or second-tier supplier to the prime that already serves Shake Shack. The prime gets diverse-spend credit it can report, you get the volume, and you build the track record that eventually makes a direct relationship credible. Identify who distributes into Shake Shack's categories, then pitch their supplier-diversity or strategic-sourcing team, not Shake Shack's.
Start where the door is actually openThe realistic order of operations: pick your category, prep a capability statement, submit through the right channel (ingredient form for food, compliance-aligned outreach for non-food), and request portal access once a buyer engages. Use your certification as a credential, not a lead, and work the Tier-2 angle through the primes in parallel.
If you'd rather start with companies that publish real, active supplier-diversity programs and clear Tier-2 reporting, our corporate program directory lists who actually has one and how to apply. It's a faster first win than chasing a door that's only half open.
