Are you tired of wasting your budget on agencies and disconnected teams? Fifth Shelf is an ecommerce accelerator that buys your inventory, funds ad campaigns, and drives growth across Amazon, Walmart, TikTok Shop, and more. All while you stay in control of your brand.

Key Takeaway:
Fifth Shelf is a modern ecommerce accelerator. We partner with brands through inventory-backed or execution-based growth models. This approach combines marketplace expertise, ad funding, content development, and global channel expansion under one system.
What Is Fifth Shelf?
Fifth Shelf is an ecommerce accelerator tailored for brands selling on platforms like Amazon, Walmart, TikTok Shop, and beyond. Unlike traditional resellers or marketing agencies, we buy your inventory upfront. We also plug in our full-stack growth team. This means you get execution, strategy, and ad support without the overhead.
Our team has managed over 10,000 SKUs, invested more than $30 million in product, and boosted conversion and market share across numerous verticals.
Whether you’re a CPG brand looking to scale through retail media or a DTC operator expanding to Amazon, Fifth Shelf provides the infrastructure and strategy you need to grow successfully.
Our Core Growth Models
In this model, we purchase your inventory at wholesale rates. To further invest in your growth, we allocate an additional 5% of our spend to ads and management. We handle everything—from advertisement campaigns to listing optimization.
You don’t pay retainers or hire agencies. We earn by reselling inventory. This structure ensures we only win when your products sell.
What’s included:
Inventory purchase
Paid media (Amazon PPC, DSP, Meta, TikTok)
Listing optimization (SEO, A+ content)
Performance-based reorders
Data-backed strategy
Full creative execution (photo, video, brand store)
Ongoing reporting through our internal Partner Portal
This model is for brands that want to maintain inventory control but require execution across advertising, SEO, and creative strategies. Fifth Shelf acts as your outsourced ecommerce team—without bloated retainers or disconnected vendors.
What CSP includes:
Cross-channel advertising (Amazon, Walmart, Meta, Google)
PDP optimization and A+ content
Creative production (images, videos, UGC)
Marketplace expansion: 1P vendor setup and global 3P launches
MAP enforcement and unauthorized seller removal
Legal and operational cost consulting
Optional integration with Fifth Shelf Fulfillment

Reinvestment in Your Growth
