The Allbirds chapter has closed. Now operating as Smartbird — a company focused on AI infrastructure that continues trading under the BIRD ticker — shares rocketed 39% higher Wednesday as the official rebrand took effect.
Back in March, the business offloaded the Allbirds brand along with all footwear-related assets to American Exchange Group for $39 million. This transaction paved the way for a complete transformation into AI data-center operations, a strategy initially revealed in April. Following that initial AI pivot announcement, BIRD stock experienced an astronomical single-day rally of nearly 600% — though shares have subsequently retreated approximately 68% from those highs.
Wednesday’s 39% rally pushes the stock to roughly 25% gains year-to-date.
The company has tapped Nadia Carlsten as its new chief executive to spearhead this strategic shift. Her credentials include a doctorate in engineering, leadership experience in product development at Amazon Web Services’ quantum computing division, and prior CEO experience at AI company DCAI. Additionally, she has served as an advisor to the World Economic Forum on artificial intelligence and computing matters.
Carlsten takes over from outgoing CEO Joe Vernachio. Annie Mitchell continues in her role as CFO, while Lily Yan Hughes assumes the position of board chair.
Smartbird’s Business Strategy Explained
The company’s approach centers on deploying customized chip clusters tailored to individual client needs, avoiding the speculative construction of massive infrastructure facilities. This strategy aims to minimize initial capital outlays while providing midmarket enterprises access to dedicated AI computing power that’s typically difficult to obtain from major cloud platforms — either due to prohibitive costs or data security requirements.
According to the company, Smartbird is currently engaged in active negotiations with prospective clients and is engineering its initial cluster installations.
To finance this infrastructure expansion, the company has doubled a previously disclosed convertible bond facility from $50 million to $100 million. These funds are specifically allocated for graphics processor purchases.
The Comeback Challenge
The market capitalization story is striking. BIRD reached a valuation approaching $4 billion after its 2021 public debut. By Tuesday’s market close — prior to Wednesday’s surge — the company’s market cap had plummeted to merely $35 million.
Smartbird now enters a competitive arena dominated by players like CoreWeave (CRWV) and Nebius Group (NBIS), which command multi-billion dollar valuations backed by substantial financial resources and established data center networks.
Carlsten spoke directly to this hurdle: “AI is rapidly becoming mission-critical for organizations across every industry. Yet many organizations lack a practical path to deploy and operate the dedicated infrastructure these workloads require.”
Whether Smartbird can successfully establish a competitive position in this market is uncertain. Currently, the company maintains it possesses sufficient capital, a clearly defined strategy, and leadership with relevant experience to make the attempt.
The expansion of the convertible bond facility to $100 million represents the latest tangible financial commitment to this vision.
