A San Francisco Airbnb host is suing The Bot Company, the $2 billion robotics startup founded by ex-Cruise CEO Kyle Vogt, for allegedly using his home as a secret robot testing lab. Sean Donovan claims workers booked his Portola neighbourhood property under false pretences in April, posing as remote workers from Thailand. He is seeking $12,383 in damages.

What Donovan found was not a group of digital nomads. Using his outdoor Ring camera, he counted more than 30 people entering and leaving the house over 11 nights. He overheard some of them discussing their “shifts,” he told SFGate.

When Donovan stopped by to take out the trash, he found bundles of wires leading inside. He followed them and discovered a six-foot robot he described as looking like a “borg” from Star Trek, or a giant “Roomba with treads.” The Bot Company builds household chore robots but has shared almost nothing about its prototypes publicly.

The damage was extensive. A 70-year-old family dining table was scratched and water-marked. A Franciscan pottery set went missing. A bathroom tile was chipped, a coffee table banged up, and a broken mug had its handle glued back on. An entire shoe rack disappeared. “They came in and put everything back in a new place,” Donovan told SFGate. “Silverware in a new drawer or a different room.”

Vogt co-founded The Bot Company in 2024 with Paril Jain, the former head of Tesla’s AI division. The startup has raised more than $300 million, including a $150 million round led by Greenoaks. It is valued at approximately $2 billion, despite having revealed almost nothing about what it is building.

Vogt’s previous venture did not end well. He was CEO of Cruise, GM’s robotaxi division, which was shut down in 2024 after a series of safety incidents. GM absorbed the technical team and redirected autonomous driving work toward personal vehicles.

There is a legitimate reason to test household robots in real homes rather than sanitised labs. Domestic environments are cluttered, unpredictable, and full of objects that break. But doing it without the property owner’s consent, under a false identity, crosses a line. The lawsuit alleges unauthorised commercial R&D activity, including robotic prototype testing and filming for commercial purposes.

Other robotics companies testing in real-world environments have faced similar scrutiny. Robotaxi operators have been criticised for using public roads as de facto test tracks. The Bot Company appears to have applied the same logic to someone’s living room, and the result was a trashed house and a rare, accidental glimpse at a prototype the company would rather have kept secret.

Airbnb CEO Brian Chesky plans to back a new AI lab focused on user interaction and design, while remaining at Airbnb. The move puts him in competition with Sam Altman, whom he helped reinstate at OpenAI in 2023.

Brian Chesky has spent years as an AI kingmaker. He met Sam Altman through Y Combinator in 2006, advised him on managing OpenAI’s hypergrowth, and helped broker Altman’s return to power after the board fired him in November 2023. He was reportedly considered for a seat on OpenAI’s board.

Now he is entering competition with his protégé’s company. Chesky plans to back a new AI lab of his own, Bloomberg first reported on Wednesday, with a focus on user interaction and design. He will remain as Airbnb’s CEO and will not lead the lab himself. The details are early-stage and could change.

Why Chesky is unsatisfied

The move reflects a frustration Chesky has voiced publicly for more than a year. He said last year that Airbnb had not struck an LLM partnership because existing products were not quite ready for what he wanted to build. His argument is that travel and commerce require a rich visual interface, not the text-based chatbots that OpenAI and Anthropic have popularised.

Airbnb has not been idle on AI. The company hired Ahmad Al-Dahle, who led generative AI work at Meta including the Llama model family, as chief technology officer in January 2026. It has rebuilt its app around a large language model for conversational search, automated 40% of customer support queries with an AI bot, and rolled out AI-generated listing details and review summaries. A voice-based assistant is planned for later this year.

But Chesky appears to have concluded that buying AI from frontier labs is not enough. He wants to build at the model layer, not just the application layer.

A growing pattern

Chesky is not alone. Brett Adcock launched Hark late last year with $100 million of his own money to build a universal AI interface, then raised a $700 million Series A at a $6 billion valuation. Hark is also emphasising user interaction and hardware, with the lead iPhone designer from Apple now heading its design effort.

Mira Murati’s Thinking Machines Lab is pursuing “interaction models” that process continuous streams of audio, text, and video in real time. The common thread is a belief that the frontier labs have focused on intelligence at the expense of interface, and that the next defensible layer sits between the model and the user.

The trend carries a broader implication. When founders of Chesky’s stature stop waiting for OpenAI, Anthropic, or Google to deliver what they need and start building their own research capacity, it signals that the application layer has run into the limits of what commodity models can provide.

The Altman dynamic

The personal dimension is hard to ignore. Chesky and Altman’s relationship spans nearly two decades. Chesky met Altman through Y Combinator, which incubated Airbnb. When OpenAI took off, Chesky began meeting regularly with Altman to advise on scaling a technology company. During the November 2023 board crisis, Chesky advised Altman on public relations and rallied support among Silicon Valley executives.

Now Chesky is building an operation that will compete, at least in part, with OpenAI’s own ambitions in user-facing AI. It is unclear whether the new lab will train its own models or build specialised systems on top of existing ones. But the direction is clear: Chesky wants proprietary AI research, not an API subscription.

What we do not know

Nearly everything about the lab remains unspecified. There is no name, no announced team, no disclosed funding amount, and no timeline. Chesky’s commitment to remaining at Airbnb raises questions about how much of his attention the new venture will receive, and whoever leads it will inherit a founding chair whom TechCrunch described as “known as a micromanager.”

What is clear is the thesis. Chesky has watched the AI lab landscape from closer than almost anyone outside it, and he has decided that the interface problem, making AI useful in rich, visual, consumer-facing contexts, is important enough to warrant its own research operation. Whether a part-time founder can build one that matters is the open question.

Alphabet’s Verily is seeking EPA approval to release 64 million Wolbachia-carrying male mosquitoes in Florida and California over two years  to suppress Aedes aegypti populations. Earlier Debug trials achieved up to 95% reductions in biting mosquitoes in Fresno and 70%+ dengue reduction in Singapore.

Verily, the health and life sciences subsidiary of Google parent Alphabet, has asked the US Environmental Protection Agency for permission to release up to 64 million lab-bred mosquitoes (up to 32 million per year) across Florida and California over two years. The proposal, submitted under the company’s Debug initiative, would deploy male Aedes aegypti mosquitoes carrying Wolbachia bacteria into areas where the species transmits dengue fever, Zika virus, yellow fever, and chikungunya. The EPA is reviewing the application under an experimental use permit, with a public comment period running through early June.

The approach is elegant in its biology. Wolbachia is a naturally occurring bacterium found in roughly 60% of insect species, but not in Aedes aegypti. When lab-reared males carrying Wolbachia mate with wild females that lack it, the resulting eggs do not develop. The males do not bite, do not transmit disease, and cannot reproduce with each other, making the release self-limiting. Each generation of released males reduces the wild population without introducing permanent genetic changes or synthetic chemicals into the environment.

The results so far

Debug has been running field trials since 2017. In Fresno, California, the programme achieved reductions in biting female Aedes aegypti populations of 68% in its first year, over 95% in 2018, and 84% in 2019. The results put it among the most effective biotech-driven population control methods tested at scale in the United States.

In Singapore, where the government has deployed Wolbachia-based mosquito control as part of its national dengue strategy, releases of sterile males achieved 80% to 90% suppression of Aedes aegypti populations and a more than 70% reduction in dengue cases within six to 12 months. The World Mosquito Program, which operates independently of Verily, has deployed Wolbachia across 14 countries using a different approach that infects both male and female mosquitoes to establish self-sustaining Wolbachia populations in the wild.

How Verily scales it

The challenge with mosquito releases is not the biology but the logistics. Releasing millions of male mosquitoes requires breeding them at scale, sorting them from females with near-perfect accuracy (releasing females would increase biting), and distributing them across target areas at the right density and timing. Verily is applying its parent company’s AI capabilities to each of these steps.

The Debug programme uses AI-powered mosquito sorting systems that can separate males from females using computer vision, automated breeding technology that maintains colony health at industrial scale, and specialised release platforms, including drones and ground-based dispensers, that distribute mosquitoes across target zones. The total programme scope is 64 million mosquitoes, broken down to 16 million per state per year over the two-year permit period. Some outlets have reported the figure as 32 million, which appears to refer to the annual release across both states rather than the full two-year total.

The debate

Not everyone is comfortable with the idea of a tech company releasing tens of millions of insects into the wild. The intersection of AI, biotech, and public health raises questions about corporate involvement in ecological interventions, long-term environmental effects, and community consent. Critics have raised concerns about whether reducing one mosquito species could affect the food chain, whether Wolbachia could transfer to non-target species, and whether corporate-led biological interventions should require stricter oversight than the current EPA permit process provides.

Proponents counter that Aedes aegypti is an invasive species in the Americas, not part of the native ecosystem, and that its removal would have minimal ecological impact. The species is responsible for hundreds of millions of dengue infections annually worldwide, with cases rising sharply as climate change expands the mosquito’s range into previously temperate regions. AI-driven approaches to biological and medical challenges are producing results that traditional methods have struggled to match.

Why it matters for tech

Debug is one of the few surviving projects from Verily’s original mission to apply technology to life sciences at scale. Alphabet has restructured its health ambitions multiple times, shutting down or spinning off various initiatives. While most of Big Tech’s resources flow toward AI infrastructure, Verily’s mosquito programme represents a different kind of applied technology: using automation, computer vision, and logistics software to solve a public health problem that kills hundreds of thousands of people each year.

If the EPA approves the permit, Florida and California would become the largest US deployment of Wolbachia-based mosquito control to date. The decision is expected after the public comment period closes, with releases potentially beginning in late 2026 or early 2027.
