Travis Kalanick, the co-founder and former CEO of Uber who was ousted in 2017 amid a toxic workplace scandal, has made a stunning return to the tech spotlight. His new venture, Atoms, has raised $1.7 billion in a massive funding round that includes an unexpected participant: Uber itself. The round was led by Andreessen Horowitz (a16z), with co-founder Ben Horowitz joining Atoms’ board. Other investors include Bain Capital, Fifth Wall, and credit facilities from JPMorgan, Goldman Sachs, Bank of America, Wells Fargo, and Barclays. The company has not disclosed its valuation, but the sheer size of the raise—reportedly one of the largest a16z has ever written—signals immense confidence in Kalanick’s vision.
Atoms is Kalanick’s attempt to build what he calls an “atoms-based computer”—a system that treats physical industries as software-enabled platforms. The company operates in near-total stealth, but reports indicate it is divided into three verticals: Atoms Food (integrating CloudKitchens, Kalanick’s ghost-kitchen venture), Atoms Mining (using autonomous machines for extraction, built on the acquisition of Pronto, a startup by former Uber and Google engineer Anthony Levandowski), and Atoms Transport (described as a “wheelbase for robots”). The target sectors are the unglamorous backbone of the economy: mining, construction, heavy transport, and food production.
Kalanick’s pitch is a continuation of the idea that propelled Uber: turning the physical world into something software can run. He argues that manufacturing is a processor, real estate is storage, and transport is the network. Uber digitized transportation for people; CloudKitchens digitized food preparation; now Atoms aims to digitize entire industrial sectors. He calls this transformation the “Age of Atoms.”
A history of ambition and controversy
Travis Kalanick’s career has been defined by bold bets and frequent clashes. He co-founded Uber in 2009, disrupting the taxi industry worldwide and turning the company into a $70 billion giant. But his aggressive leadership style also led to a culture of sexual harassment and discrimination allegations, which came to light in 2017. Investor pressure forced him to resign as CEO, though he remained on the board until 2019. After leaving Uber, he founded CloudKitchens, a startup that leases commercial kitchen space for delivery-only restaurants. That venture also faced controversy, including allegations of exploiting immigrant drivers and violating health codes.
Now, with Atoms, Kalanick is aiming even higher. The $1.7 billion raise is one of the largest in history for a robotics startup, eclipsing many self-driving car and humanoid robot companies. The involvement of Uber is particularly notable: the company that once pushed him out is now funding his next act. Uber’s investment suggests a strategic interest in industrial automation, perhaps as a future partner for its own logistics operations. However, it also raises questions about Kalanick’s legacy and whether the public is ready to embrace his return.
Specialized machines over humanoids
Atoms takes a distinct approach from many of its peers. While companies like Tesla, Boston Dynamics, and Figure pour billions into general-purpose humanoid robots, Kalanick and Horowitz argue that specialized machines are better suited for harsh industrial environments. Humanoids are complex, expensive, and often fragile; purpose-built robots can be more durable, efficient, and easier to deploy at scale. This is a pointed bet against the hottest trend in physical AI. Horowitz stated that “purpose-built hardware copes with brutal industrial environments far better than a humanoid could.”
The strategy is reminiscent of Kalanick’s playbook at Uber: focus on a specific, high-value problem and solve it with a relentless, software-first approach. In mining, for example, autonomous haul trucks and drilling systems can operate 24/7, reducing costs and improving safety. In construction, robots can lay bricks, pour concrete, or perform inspections. In food, CloudKitchens already operates thousands of delivery-only kitchens, using software to optimize cooking and delivery times. Atoms aims to integrate these verticals under one roof, creating a unified platform for industrial automation.
The Levandowski factor
One of the most intriguing elements of Atoms is the involvement of Anthony Levandowski, a former Uber and Google engineer who was at the center of a high-profile trade secrets case. Levandowski founded Pronto, a startup (later acquired by Atoms) that developed autonomous driving technology. He had previously worked on Google’s self-driving car project and later started Otto, which Uber acquired in 2016. That acquisition led to a legal battle between Uber and Google’s Waymo, with Levandowski accused of stealing trade secrets. He pleaded guilty to one count of trade secret theft in 2020 and was sentenced to 18 months in prison, but received a presidential pardon from Donald Trump in January 2021.
Kalanick and Levandowski have a history: at Uber, Kalanick was a vocal proponent of autonomous vehicles and aggressively pursued Levandowski’s technology. Now they are reunited at Atoms, where Levandowski’s expertise in autonomy is critical for the mining and transport divisions. The collaboration has raised eyebrows, given the legal baggage, but it also underscores Kalanick’s willingness to bet on controversial figures if he believes they can deliver.
Industrial AI: a trillion-dollar opportunity?
Proponents of Atoms argue that the market for industrial automation is enormous and underpenetrated. Mining alone is a multi-trillion-dollar industry; construction and heavy transport dwarf even that. A16z partner (whose name was not disclosed) called the round “the largest cheque the firm has ever written,” and another investor predicted Atoms could be worth a trillion dollars within a decade. Horowitz summed it up: “Travis is back.”
However, skeptics note that Atoms has yet to deploy a significant number of industrial robots at scale. The company has revealed a grand vision and a very large bank balance, but little in the way of proven technology or customer contracts. The valuation is a mystery, and Kalanick’s track record at Uber—while impressive in terms of growth—was marred by governance failures. Is the tech industry forgiving his past because of his ambition? Or is Atoms genuinely poised to transform the physical economy in the way Uber transformed transportation?
The credit facilities from major banks suggest that institutional investors are taking the bet seriously. But building heavy machinery requires huge capital expenditures and long development cycles. Atoms will need to navigate regulatory hurdles, safety standards, and competition from established players like Caterpillar, Komatsu, and other industrial giants that are also investing in autonomy. Kalanick has never built hardware before; his expertise lies in software and platform businesses. Whether he can translate that to the world of steel, sensors, and dust remains to be seen.
A comeback shaped by unfinished business
Kalanick himself calls the round “unfinished business.” The phrase echoes his turbulent departure from Uber and his desire to prove that his vision was right, even if his execution was flawed. The participation of a16z, Bain Capital, and Fifth Wall—alongside major banks—gives Atoms credibility and financial firepower. But the true test will be in the next few years, as Atoms moves from stealth to deployment and begins to show results.
The robotics and AI landscape is crowded, but Kalanick’s approach stands out for its focus on purpose-built machines and its integration of multiple verticals under a single software layer. If successful, Atoms could become the operating system for heavy industry, just as Uber became the operating system for urban transportation. If it fails, it will be remembered as one of the most audacious bets in tech history.
For now, the tech world is watching. Kalanick has raised $1.7 billion, lined up elite backers, and recruited a controversial engineer. The next chapter of his story will be written in dirt, dust, and data—not just software.
