Allbirds Rebrands Again, Names New CEO, Stock Rises 34% as AI Pivot Deepens

From Wool Sneakers to AI Infrastructure

Allbirds no longer sells shoes. It barely exists as the company Tim Brown and Joey Zwillinger launched in 2015 to make sustainable footwear from natural materials.

On Wednesday, the company announced its second name change in roughly two months, according to CNBC. It is now called Smartbird. The new CEO is Nadia Carlsten, who replaces Joe Vernachio and simultaneously joins the board.

Shares of the stock, still trading under the ticker BIRD, rose 34% on the news as of Wednesday morning trading.

Who Is Nadia Carlsten?

Carlsten's resume is substantive. According to CNBC, she previously led Amazon Web Services' quantum computing center and worked at the U.S. Department of Homeland Security. Most recently she served as CEO of DCAI, an AI infrastructure company that partnered with Nvidia and operates a supercomputer called Gefion.

The Rebrand Timeline

February 2026: Allbirds shuttered its U.S. full-priced retail stores.

March 2026: The company sold its footwear assets to American Exchange Group for $39 million, according to CNBC.

April 2026: Allbirds rebranded to NewBird AI, announced a pivot to AI compute infrastructure and hardware, and watched its market cap surge sevenfold.

June 17, 2026: The company rebrands again, this time to Smartbird, and installs Carlsten as CEO.

Two name changes in two months. One credentialed CEO hire. ZERO revenue yet reported from the new AI business in these sources.

The Legitimate Concern

The history of companies chasing technology manias with a name change and a press release is not encouraging. During the crypto boom, multiple companies added "blockchain" to their names or announced token projects and watched their stocks spike, only to deliver nothing durable. CNBC draws that parallel explicitly.

Allbirds went public on the Nasdaq in 2021, surging 90% on its debut. Then it spent years losing money and market share in a crowded footwear market. The brand closed stores. It sold its core assets for $39 million. A company that couldn't sustain a shoe business is now claiming it will build AI compute infrastructure. A shoemaker pivoting to AI compute is not automatically fraudulent, but it is a claim, not a track record.

The Counter-Argument

Pivots happen, and sometimes they work. CoreWeave, now a publicly traded AI infrastructure firm, started as a crypto mining operation. The pivot was real and the business became real. Carlsten's background at AWS quantum and DCAI gives Smartbird something NewBird AI arguably lacked two months ago: an operator with actual infrastructure credentials.

The $39 million from the shoe asset sale gives the company some runway. How much, and what the current cash position is, is NOT established in these sources.

The WWD Source Gap

The WWD/Footwear News source included in this reporting does not contain substantive reporting on the rebrand or the CEO hire. Its content is largely navigation and unrelated shoe industry headlines. Nothing from that source adds to or contradicts the CNBC account, so the CNBC reporting is the sole substantive basis for the facts above.

The Open Question

The specific unresolved issue here is whether Smartbird has any AI infrastructure contracts, revenue, hardware assets, or partnerships already in place, or whether it is, as of June 17, 2026, a ticker symbol and a press release. Carlsten's DCAI reportedly partnered with Nvidia, but whether that relationship transfers to Smartbird has NOT been confirmed in these sources. That answer will determine whether this is a pivot or a pump.
