Amazon Aggregators: Buying Third-Party Sellers - [Business Breakdowns, EP. 35]

In plain words

This piece explains Amazon aggregators—companies that buy third-party seller stores on Amazon. The guest argues the market is undervalued: ~$300B revenue with high margins, but only ~$8B capital has entered, leaving room for early movers. Key holdings: Thrasio (pioneer, admired), Wonder Brands (invested, focuses on Latin America), and Helium 10 (a seller analytics tool, recently acquired). The idea: buy stores' reviews and rankings, scale operations, but risk Amazon's ad policy changes breaking the moat.

Amazon Aggregators: Buying Third-Party Sellers - [Business Breakdowns, EP. 35]

At a Glance

Guest Ali Hamed (Partner at CoVenture) deconstructs the emerging investment category of Amazon aggregators. The core thesis: by acquiring third-party seller stores on Amazon, aggregators build unique moats and achieve rapid growth, yet the market remains severely undercapitalized. The most impactful judgment of the episode: the market generates approximately $300 billion in annual revenue and roughly $60 billion in EBITDA, but only about $8 billion in financing has entered — this capital misalignment means early entrants still have enormous arbitrage opportunities.


Theme 1: What Are Amazon Aggregators — A Severely Undervalued Market

Ali Hamed argues that Amazon aggregators are essentially acquiring "digital real estate" on the Amazon platform — a moat built on reviews and rankings.

Amazon third-party sellers fall into three categories: resellers (low margin), suppliers (selling to Amazon for resale), and the most critical FBA (Fulfilled by Amazon) sellers — who design their own products, source from OEMs, store inventory in Amazon warehouses, and sell via Amazon's storefront. Aggregators acquire all assets of these FBA stores (ASINs, SKUs, inventory, reviews, rankings) and then operate them at scale.

The market size far exceeds most people's perception:

  • Annual revenue of approximately $300 billion, growing at a 30%-50% CAGR
  • Net profit margin of about 15%-25%, corresponding to roughly $60 billion in EBITDA
  • With a conservative estimate of 4x leverage, it could theoretically accommodate $240 billion in debt capital, but only about $80 billion has entered so far

Hamed notes that the P&L of these stores is highly variable: for every $100 in revenue, roughly $30 goes to COGS, $40 to Amazon FBA fees, and $10 to management fees — fixed costs are extremely low, and a 10% drop in revenue reduces EBITDA by only about 12%.


Theme 2: Why Sellers Are Willing to Sell — The Pain of Being Small but Beautiful

Ali Hamed argues that small-scale Amazon sellers face a "death spiral" risk, which is the fundamental reason aggregators can acquire them at low multiples.

The core driver for sellers to exit is not poor business performance, but the difficulty of operations:

  • High cash flow volatility: Growth requires continuous reinvestment in inventory, and the conversion rate from EBITDA to cash is low
  • Fragile supply chain: No redundancy — no backup 3PL, no backup truck broker, no quality control staff in China
  • Stockouts are fatal: Repeated stockouts lead to ranking downgrades by Amazon, and competitors will ramp up ad spending to "crush you"
  • Insufficient scale, no support: Small sellers lack an Amazon Seller Account Manager
  • High personal cost: Many sellers operate solo, spending consecutive Christmases packing and shipping orders

Acquisition multiples: typically 3-5x EBITDA. Hamed emphasizes that despite capital inflows, the growth in sellers' willingness to sell "keeps pace with the speed of capital entry," so multiples have not risen significantly — only structurally adding earnouts and seller notes.


Theme 3: The "Thousand Little Secrets" of Aggregators — Operations, Not Branding

Ali Hamed argues that the core competitive advantage of aggregators is not brand building or vertical integration, but a deep understanding of the Amazon ecosystem — "This is a business of 1,000 little secrets, not one big secret."

Why vertical integration is not the focus:

  • Products that sell well on Amazon are often commoditized products, making it difficult to build a brand
  • Cross-category cross-selling has proven to be a "myth" — customers who buy coffee filters and shower curtains have almost no overlap
  • Amazon and Shopify operate on different logics: Amazon suits products that are hard to brand, while Shopify suits high-ticket items with a story to tell

Real value creation lies on the revenue side:

  • Supply chain redundancy and inventory planning (avoiding stockouts)
  • Advanced PPC strategies (most small sellers do not use Amazon DSP)
  • International expansion: "Transplanting" 50,000 reviews from the US site to German/French/Japanese sites, instantly becoming the top-ranked seller
  • Each aggregator has its own "150-step operations manual"

Organizational structure: Operates on a "brand manager-team" model, with each team managing a set of ASINs. The most distinctive functions are the supply chain team and the finance team — the latter must simultaneously handle M&A, financing, inventory financing, accounts receivable financing, and other multi-layered capital structures.


Theme 4: Amazon Risk – The Biggest Variable Is Also the Greatest Certainty

Ali Hamed argues that Amazon has no incentive to "steal" aggregators' business, but changes in advertising policy pose the greatest risk.

Why Amazon will not directly compete:

  • Amazon earns a 40% commission from third-party sellers without bearing inventory risk—this is a high-margin, zero-risk business.
  • If Amazon used its data advantage to operate its own products, it would face antitrust pressure.
  • Large categories already have enough competitors, while small categories offer negligible incremental value to Amazon.

Risks that truly warrant attention:

1. Ad slot expansion: If Amazon increases the number of ad slots on search results pages from the current count to 10, it would fundamentally alter ranking logic—well-funded sellers could "buy" top positions, undermining the review moat.

2. Rising FBA fees: 40% → 41% → 42%, steadily eroding profits like a thousand cuts.

3. Supply glut: Too many entrants flooding the third-party seller market, leading to ever-finer category segmentation and intensifying competition.

4. Rise of other platforms: Third-party seller platforms such as Target and Home Depot may divert traffic.

Hamed suggests Amazon adopt a franchise model similar to McDonald's to set the rules—allowing aggregators to exist while preventing any single entity from monopolizing a category.


Theme 5: Investment Framework – Breaking the "Software First" Mindset

Ali Hamed argues that most VCs miss out on an asset class capable of generating 20–50x returns simply because "it's not a software company."

Why VCs should rethink:

  • These companies possess the core attributes of software firms: high growth, high barriers to entry, and low equity requirements.
  • The difference lies in: low capital efficiency (requiring substantial debt), but high equity efficiency – because high leverage (LTV of 80–90%) allows a small equity stake to mobilize a large asset base.
  • The barriers inherent in the assets themselves (reviews, rankings) are real, but differentiation among aggregators is minimal – the investment is in the "jockey," not the "horse."

Hamed's screening criteria:

  • Only invest in early-stage aggregators valued below $100 million.
  • Seek teams with quarter-over-quarter growth of 50%.
  • Founders must have "traumatic experiences" – having endured stockouts, malicious negative reviews, supplier defections, and other hardships.
  • Reject teams that are "overvalued" or "too slow to act."

Analogy: This is more like a franchise business than a tech startup – much like McDonald's franchisees, each looks similar on the surface, but some make substantial profits while others lose money; the difference lies in execution details.

Judgments Worth Remembering

1. "This is a business of 1,000 small secrets, not one big secret." (Ali Hamed) — The core competitive advantage of aggregators is not a single breakthrough, but being 2-3% better than competitors in every link, including supply chain, advertising, inventory, and international expansion.

2. "If you spend six months agonizing over 3.25x versus 3.5x, you go from potentially being a billionaire to needing to start a second business." (Ali Hamed) — Speed is the core variable in this market, and early-mover advantages are irreversible.

3. "These assets themselves have high barriers to entry, but there is almost no differentiation among aggregators." (Ali Hamed) — The investment logic is: buy the moat of the asset itself (reviews + rankings), not the brand of the aggregator.

4. "Amazon makes 40% from third-party sellers and bears no inventory risk — that's much better than doing it themselves." (Ali Hamed) — Amazon has no incentive to "steal" aggregators' business, because the platform model offers higher margins and lower risk.

5. "If Amazon increases the number of ad slots from the current count to 10, the entire ranking logic changes." (Ali Hamed) — The biggest risk is not Amazon's own retail, but a change in advertising policy that renders the "review moat" ineffective.

6. "VCs don't invest in aggregators because they forgot why they invest in software companies — not because of the word 'software,' but because of high growth, high barriers, and low equity needs." (Ali Hamed) — Aggregators possess these attributes, just in a different form.

7. "The P&L of these businesses is highly variable — a 10% drop in revenue leads to only a 12% drop in EBITDA." (Ali Hamed) — The structure with extremely low fixed costs provides downside protection, which is the fundamental difference from traditional retail M&A.

8. "You can 'transplant' 50,000 reviews from the US site to the German site and immediately become the #1 ranked seller." (Ali Hamed) — International expansion is the most undervalued value-creation tool for aggregators, something small sellers cannot accomplish on their own.
