The Aggregator Era: A Complete History, 2018–2026

In six years, the Amazon aggregator industry raised more than $15 billion, bought thousands of small brands, minted a $10 billion unicorn, and then collapsed into bankruptcies and distressed mergers. It is the largest natural experiment ever run on the question we care most about: what happens when you buy small e-commerce brands at scale? The answer turned out to be "it depends entirely on how" — and the complete history is worth telling properly, because the survivors' playbook looks nothing like the original one.

The original insight (2018–2019)

Thrasio's founding observation was arbitrage in plain sight: thousands of Amazon FBA businesses earning $500K–$5M were selling for 2–3x SDE because the buyer pool was tiny, while consolidated portfolios of consumer products traded at far richer values in private markets. Buy at 2.5x, professionalize the operations, and the spread is the business. Early returns looked spectacular, and the model had real logic — Amazon handled fulfillment and traffic, so integration seemed mostly administrative. By 2019 Thrasio had dozens of brands and a fundraising story that wrote itself.

The stampede (2020–2021)

The pandemic compressed a decade of e-commerce adoption into eighteen months, and capital followed. By 2021 more than a hundred aggregators operated globally — Perch, Berlin Brands Group, SellerX, Razor Group, Heyday, Elevate Brands, Cap Hill Brands, Unybrands, Olsam, Factory14 and dozens more — and the sector had amassed well over $10 billion in combined funding by 2021, much of it debt. Thrasio alone raised roughly $3 billion. At peak, aggregators collectively closed multiple acquisitions per week, and the competition bid entry multiples from 2.5x toward 4–8x for premium assets. Every turn of multiple expansion was a windfall for sellers — and a layer of risk for buyers who would need everything to keep going right.

Phase	Years	Funding Climate	Typical Entry Multiple	Defining Event
Proof of concept	2018–19	Early VC, modest debt	2–3x SDE	Thrasio's first ~50 acquisitions
Mania	2020–21	$10B+ raised in 2021	4–8x	Weekly deal cadence industry-wide
Reckoning	2022	Rates up, windows shut	Bid-ask freeze	Portfolio revenue mean-reverts
Restructuring	2023–24	<$100M industry-wide	1.5–2.5x, heavy structure	Thrasio Chapter 11; Razor buys Perch
Consolidated era	2025–26	Selective, operator-led	2.5–3.5x quality-adjusted	A few platforms absorb the rest

What actually broke

Leverage met mean reversion. Portfolios were assembled with roughly four dollars of debt per equity dollar at prices set during a once-in-a-generation demand spike. When post-pandemic revenue reverted 20–40% across categories, fixed debt service converted operating softness into existential crisis. Integration turned out to be real work. The "Amazon does the operations" assumption ignored inventory forecasting, ranking defense, review management, and supplier relationships across hundreds of unrelated SKUs — Thrasio's own restructuring acknowledged teams of ten doing the work of two. And most of the assets were platform positions, not brands. A typical acquired "brand" was an Amazon search ranking with a logo attached — an asset that depreciates the moment the algorithm shifts or a factory-direct competitor undercuts the listing. The industry had, at scale, repeated the classic channel-concentration mistake — building enterprise value on reach it did not own — that earlier social-commerce booms had already demonstrated.

The consolidation endgame (2023–2026)

The unwind was orderly only in places. Thrasio — once valued near $10B — filed Chapter 11 in February 2024, emerging months later focused on a fraction of its 200+ brands. Within days, Berlin-based Razor Group acquired Perch — the largest US aggregator — raising $100M+ at a combined $1.7B enterprise value carrying roughly $400M of debt, having already absorbed Factory14, Valoreo, and Stryze. SellerX took over Elevate Brands. Heyday and Branded merged to form Essor. Cap Hill Brands and Juvo+ combined into Infinite Commerce, which then bought Dragonfly and Moonshot Brands. By 2025, industry reporting pointed at still-larger mergers in negotiation. A hundred companies became a handful — each now preaching brand equity, channel diversification, and discipline.

What the era proved — and disproved

Disproved: that buying speed is a moat, that leverage substitutes for operations, that platform rankings are durable assets. Proved, almost accidentally: that thousands of founders want clean exits at fair multiples; that shared infrastructure genuinely lowers operating cost when integration is done slowly and properly; and that disciplined buyers who held their entry multiples and avoided debt-fueled pacing — mostly smaller operators who never made headlines — compounded straight through the crash. The aggregator era didn't kill the buy-and-operate thesis. It stress-tested it in public and published the results for anyone willing to read them.
