What is Allbirds?
Allbirds is a footwear brand known for wool runners, tree-fiber sneakers, and a sustainability-first direct-to-consumer identity. As of June 2026, the operating story is unusual: the former public company completed the sale of the Allbirds brand and footwear assets to American Exchange Group and renamed the issuer Smartbird, Inc.
Allbirds began as a direct-to-consumer shoe company built around simple design, natural materials, and lower-impact manufacturing. It went public in 2021, but revenue declined after the pandemic-era retail boom, stores were closed, and fiscal 2025 net revenue fell to about $152.5 million with a $77.3 million net loss.
The June 2026 profile therefore separates the consumer brand from the public issuer. Allbirds.com remains the brand storefront for shoes, while Nasdaq ticker BIRD now refers to Smartbird, an AI infrastructure company led by Nadia Carlsten after the asset sale. For directory purposes, Allbirds is best read as a licensed/owned footwear brand in transition rather than a normal standalone public shoe company.

How does Allbirds make money?
The brand makes money from footwear and apparel sales through ecommerce, wholesale/distributor channels, and a reduced retail footprint.
Before the 2026 asset sale, Allbirds sold primarily through direct ecommerce, company stores, and selected wholesale or distributor relationships. Public filings show the model was pressured by lower demand, international distributor transitions, store closures, and elevated marketing spend; Q1 2026 revenue was about $22.3 million before the footwear asset sale closed.
Current consumer pricing is product-specific rather than a subscription model: Allbirds shoes commonly sit in mainstream premium sneaker price bands, with sale pricing varying by style and season. Because American Exchange Group now owns the footwear assets, go-forward margins, licensing structure, and wholesale mix have not been fully disclosed; sellers should not assume the old public-company cost base still applies.
Who leads Allbirds?

Allbirds is no longer best described by private funding rounds: it went public in 2021, later sold its footwear assets for $39 million, and the renamed Smartbird issuer expanded a convertible financing facility to $100 million in June 2026.
The capital history starts with venture funding that built the direct-to-consumer footwear brand, followed by a November 2021 IPO at a multibillion-dollar valuation. The public-market chapter was difficult: revenue fell, the company reported a fiscal 2025 loss of $77.3 million, and the brand assets were sold to American Exchange Group for $39 million in 2026.
After the sale, the public issuer renamed itself Smartbird and doubled its convertible financing facility from $50 million to $100 million to fund an AI infrastructure strategy. As of June 19, 2026, BIRD traded as a micro-cap public company, so the relevant seller signal is restructuring and new ownership, not a fresh consumer-brand growth round.
