When Allbirds made the leap into artificial intelligence back in April, it seemed like a joke straight out of a Silicon Valley satire come to life. This direct-to-consumer shoe company, known for its lightweight sneakers that epitomized tech industry fashion, had found yet another trend to chase. The move followed the classic meme stock playbook made famous by GameStop: Take a struggling public company, attach it to the hottest craze, and watch the stock price soar as retail investors pile in. And it worked. The company sold its footwear business for $43 million, raised an additional $100 million through the stock market, and rebranded as Smartbird. Now, the challenge falls to Nadia Carlsten to make this new venture succeed. A former AWS executive with a PhD in engineering, Carlsten most recently led the European computing firm DCAI before stepping into her role as Smartbird's CEO yesterday. "The shoe business officially closed yesterday, so that's all taken care of… My first priority right now is assembling the leadership team—looking for someone to lead infrastructure operations, for instance."

Think of it as a startup with a single founder and an exceptionally large seed round. What comes next is less certain. Smartbird aims to become an AI infrastructure provider, tapping into the seemingly endless demand for computing power to train and run deep learning models. However, unlike neoclouds that constantly arbitrage chip prices against GPU time or inference token costs, Carlsten plans to focus on more carefully managed deployments. The ideal Smartbird customers need direct control over the servers running their models—often for political or business-model reasons—and prioritize data sovereignty over the scalability of public cloud services. Carlsten couldn't yet estimate the size of this market, arguing it's still in its early stages since many companies are only piloting AI tools. At DCAI, she worked with Novo Nordisk and other European firms that place a high value on data sovereignty or run custom models—"we certainly have clients in the pharmaceutical, energy, financial, and public sectors," she said. From Carlsten's perspective, this means Smartbird isn't competing with hyperscalers or neoclouds, but rather with internal company projects. That said, established players already operate in this space—Hewlett Packard offers a single-tenant managed AI compute service, as does data center giant Equinix. It's a legitimate business model, but it's unclear whether it offers the same growth potential as cloud services, where expansion is the ultimate goal. Carlsten expects to have compute clusters deployed for several customers by the end of the year. Other startups, like inference cloud provider General Compute, have bigger ambitions—the company announced a $300 billion chip order when it emerged from stealth mode last month. Carlsten says she doesn't need massive chip commitments to realize Smartbird's vision, because her potential customers' needs range from hundreds to thousands of chips—"it's not about large scales and huge numbers of GPUs; it's more about the agility of these clusters and having control over the infrastructure stack."

Smartbird is also unlikely to compete on price, since cloud services go to great lengths to optimize chip usage around the clock to offer the most affordable computing. However, Carlsten suspects that companies with specialized workflows could operate more efficiently with their own servers. The demand for AI infrastructure is a powerful market force, driving up stock prices for chipmakers, cloud providers, and energy companies, and even convincing investors that orbital data centers are a viable concept. But Carlsten insists that Allbirds' transition was carefully planned. "It wasn't, 'Let's just do AI because it's AI and it's hot,'" said Carlsten, who will receive a $700,000 annual salary and was awarded approximately $9 million in stock to take the job. "It was really about whether we have a chance to build a business over time that can find this niche in the market and grow sustainably."

When Allbirds made the pivot, one casualty was its public benefit corporation status, which had been designed to enshrine the sustainability commitments central to the shoe company's brand. PBC charters are often used by companies to highlight non-financial promises. OpenAI, for instance, is a PBC focused on AI safety. This change in direction, however, suggests that PBCs are far from unbreakable. Carlsten stated that Smartbird's board has made a long-term commitment to execute her AI strategy.
