Instead of Running Ads, Let Other Retailers Sell for You

01 /The Concept

Carro has built what it calls a "modern dropshipping platform for online retailers."

Dropshipping, as a refresher, is the business model where a customer places an order on a storefront, the store passes that order to a supplier, and the supplier ships directly to the customer. The retailer pockets a commission without ever touching inventory or managing logistics.

Carro's target audience is existing online stores that already run their own sales. The platform gives them a simple way to expand their product catalog and generate incremental revenue – without spending on inventory or handling fulfillment.

According to Carro, merchants who plug into the platform can increase their average order value by 2.8x and revenue by 3.5x.

Merchants choose exactly which products from the Carro catalog they want to surface in their own storefront – and adding each one takes a single click. The catalog currently holds over one million SKUs across fashion, footwear, kids' products, electronics, food, beauty, fragrances, jewelry, and more.

Suppliers on the platform can be manufacturers looking to open new distribution channels, or online retailers trying to move excess inventory. In fact, a single store can use Carro on both sides simultaneously – acting as a storefront for other brands' products while also supplying its own products to other stores.

Suppliers set their own retail prices and commission rates; retailers choose products based on how much they can earn. Market forces take care of the rest.

When a product sells through a partner storefront, the supplier receives payment immediately – net of the retailer's commission and the platform fee. As a bonus, the buyer's contact details flow back to the supplier through the platform, enabling future marketing campaigns.

Retailers pay $149 or $299 per month, plus a 7% or 5% transaction fee on items sold. Suppliers pay nothing.

Carro first appeared in [a related review](/review/delo-ne-v-universalnosti) back in fall 2021. The startup has since closed a new $14M funding round, bringing total investment to $50M.

02 /Why It Matters

For most online retailers – anyone not selling an iPhone-caliber blockbuster – the primary driver of revenue growth is catalog breadth. The more a visitor can buy on a single visit, the higher the store's revenue.

Carro gives retailers a frictionless way to expand their catalog at zero inventory cost – which explains the platform's appeal.

A similar order-aggregation mechanic underpins Stockly, a startup that [covered here](/review/kak-net-na-sklade) raised $17.5M. Stockly's stated goal is different – it helps retailers continue selling products that have gone out of stock. The insight: stockouts damage a store's reputation and kill repeat visits. Why return to a store that doesn't have what you need when you need it?

Through Stockly's platform, online retailers pool their inventory into a single virtual warehouse. When one store runs out of an item, the platform automatically reroutes the order to a partner store that still has it in stock.

Broader than the e-commerce angle, Carro is part of a wider trend: cross-merchant partnerships designed to mutually boost sales volumes. The trend is spreading across industries.

REPOWR ([covered here](/review/novyj-tip-marketplejsov)) raised $12.7M – some of it after publication – on a Stockly-equivalent for freight. It created a shared fleet of commercial vehicles sitting idle at carriers, which other carriers can rent to fulfill their current orders.

Paylode ([covered here](/review/dozhat-klientam-mozhno-za-chuzhoj-schjot)) started as a platform where service providers could bolt on complementary partner offers – a real estate agent could bundle home renovation or moving services, earning a commission on each. Since then it has evolved into a rewards platform: sellers can offer their customers discounts and perks sourced from partners, rewarding buyers without discounting their own margins. Paylode has raised $5.5M. D2C partnership marketing platforms follow a similar logic – AI matching one brand's audience to another's offer, eliminating paid media from the equation entirely.

The partnership concept has even reached B2B. Crossbeam ([covered here](/review/vmeste-prodadim)) and Reveal – both working on the same technical approach – let companies connect their CRMs to identify which other B2B vendors already have relationships with a prospect, so they can ask for a warm introduction. No raw CRM access is shared. Reveal has raised $54.3M; Crossbeam has raised $116.9M.

03 /Opportunities

Cold advertising keeps getting more expensive and less effective. What actually works is word-of-mouth – direct, indirect, embedded, any form. Partnerships are a kind of recommendation, even if it's as implicit as one store placing another brand's products on its shelves.

Companies are also cutting costs wherever they can – holding less inventory, leasing fewer assets. But catalog size and production capacity directly affect revenue. The tension is real.

As a result, sales-side and marketing-side partnerships – and shared-asset arrangements – have become an efficient path to growing revenue while simultaneously reducing expenses.

The catch: partnerships only scale if the process of forming them is industrialized. Manual negotiations, one-off deals, and relationship management are slow, expensive, and unreliable.

The opportunity, then, is building platforms that make partnerships fast, easy, and effective across many companies simultaneously – in different categories, with different mechanics. "Partnerships as a service" – minimum hassle, maximum leverage.

The key design questions for any partnership platform: what mutual value is being created, how partners find each other at scale, and how the mechanics get automated enough that participation requires minimal ongoing effort. The platforms that crack all three tend to be sticky – nobody leaves a network that's already working.
