Ox Security lands a fresh $60M to scan for vulnerabilities in code
Ox Security, which models risk across both AI- and human-produced code, on Wednesday announced that it closed a $60 million Series B. The round was led by DTCP with participation from IBM Ventures, Microsoft, Swisscom Ventures, Evolution Equity Partners, and Team8, and it brings Ox's total raised to $94 million.
Neatsun Ziv and Lior Arzi founded New York- and Tel Aviv-based Ox in 2021. Software and IT engineers by trade, the pair met at Check Point, where they worked on the security firm's threat prevention product lines.
Ox's platform, which TechCrunch last profiled in 2022, is aimed at both security teams and developers, offering tools to scan code in applications and secure a company's broader supply chain. Ox can model threats and even recommend fixes, assisting with code reviews and generating executive reports that highlight breaches and possible reasons they occurred.
"Over the past year, AI has significantly transformed software development," Ziv told TechCrunchw. "While these tools accelerate development for both experienced developers and beginners, they often lack the critical thinking and judgment needed to catch subtle security flaws … Ox frees up developers' time, allowing them to focus on innovation, while simultaneously improving the organization's overall security posture."

Ziv claims that Ox is analyzing over 100 million lines of code daily for around 200 customers, including eToro, SoFi, and two of its investors, Microsoft and IBM.
"Our customer base spans from Fortune 10 companies to small- and medium-sized businesses," Ziv said. "We also count military and government entities as clients, as well as federal agencies."
According to Ziv, Ox's new capital will be put toward growth and expansion as the 150-employee startup competes for market share against rivals such as Snyk, Veracode, Synopsis, and Checkmarx. Ox is generating around $10 million in annual recurring revenue — a figure Ziv anticipates will double by the end of the year — and plans to be cash-flow-positive within the next 2-3 years.
"We want to position ourselves for long-term success and this way we can focus on scaling and reaching our bigger goals," ZIv said. "We've seen significant growth in revenue, and received offers that give us the opportunity to make a leap forward. We felt it was the right time to take this step for the company."

Top Citigroup banker Andy Sieg humiliated employees with explosive tirades, made executive cry: report
Citigroup's star wealth chief Andy Sieg is being probed after at least six managing directors accused him of humiliating employees with explosive tirades — including one outburst that reduced an executive to tears, according to a report. The New York-based megabank hired white-shoe law firm Paul Weiss to investigate CEO Jane Fraser's prized recruit following complaints he mocked and undermined one of Citigroup's most prominent female executives before she left the firm, according to Bloomberg News. Sieg, 58, who Fraser personally courted at his Connecticut home to poach from Bank of America's Merrill Lynch division, allegedly unleashed expletive-filled rants and called employees' work 'pathetic' in front of their peers, sources told Bloomberg. 7 Andy Sieg, Citigroup's embattled head of wealth, is reportedly under investigation after executives accused him of tirades, humiliations and abusive treatment. Bloomberg via Getty Images 'Some of the people also described a male managing director being reduced to tears after Sieg berated him in front of colleagues while striking a tabletop,' according to the report. At the center of the complaints was Sieg's treatment of Ida Liu, 49, who ran Citigroup's private bank for 18 years before abruptly leaving in January. Liu once held the same position Fraser occupied on her climb to CEO, making her departure particularly significant. Witnesses told investigators that Sieg openly mocked Liu in meetings, undermined her authority and made disparaging comments both to her face and behind her back. His chief operating officer, Valentin Valderrabano, allegedly ordered another managing director to cut Liu out of critical business correspondence, that executive told Bloomberg News. After Liu's exit, Sieg eliminated her position entirely and replaced her with four male regional co-heads reporting directly to him, according to the report. 7 Ida Liu, who ran Citigroup's private bank for 18 years before abruptly leaving in January, was allegedly mocked and undermined by Andy Sieg. REUTERS Senior wealth executive Kristen Bitterly also became a target of Sieg's harsh treatment, prompting multiple complaints to human resources, sources told Bloomberg News. Her predecessor, Naz Vahid, quit last year after nearly 40 years at Citigroup, partly because of concerns about how Sieg treated colleagues, people familiar with the situation told the financial news agency. 7 Kristen Bitterly, another senior executive at Citi, was reportedly on the receiving end of Sieg's ire. Linkedin/Kristen Bitterly Michell Other incidents included Sieg sarcastically ridiculing an executive to colleagues immediately after the person left the room. Human resources chief Sara Wechter ordered the outside investigation as complaints piled up from both male and female executives about Sieg's conduct since joining the bank nearly two years ago, according to the report. Board chair John Dugan also received anonymous letters detailing troubling behavior from both Sieg's current role and earlier career stints, according to correspondence reviewed by Bloomberg News. Paul Weiss investigators interviewed more than a dozen witnesses, with some questioned as recently as July, before wrapping up their probe, people familiar with the matter told Bloomberg News. 7 Bitterly and Sieg are pictured in Armonk, New York, earlier this month. Linkedin/Kristen Bitterly Michell The bank refused to reveal the investigation's findings. Sieg didn't respond to requests for comment. 'It is standard practice for us to engage an outside law firm to investigate allegations made against a senior member of the management team,' Citigroup spokesperson Mark Costiglio told Bloomberg News in a carefully worded statement. Fraser, 58, who became CEO in 2021, had bet big on Sieg to transform the wealth division as part of her broader push to boost profitability. 7 Liu, once seen as a rising star who held the same role Jane Fraser occupied before becoming CEO, became a central figure in complaints against Sieg. Getty Images Sieg sits on Citigroup's 18-person executive management team and is widely viewed as a potential successor to Fraser. Under his leadership, the wealth unit posted record revenue of $2.17 billion in the second quarter while shifting focus from lending to investment management. Citigroup shares have surged 33% this year, outpacing other major banks. 'Andy is a hard-charging leader who has established a strong, client-focused franchise that is delivering revenue growth and improved returns,' Costiglio insisted. 7 Citi CEO Jane Fraser personally courted Sieg at his Connecticut home to poach him from Bank of America. Getty Images Costiglio told Reuters that 'we look forward to Andy continuing to drive strong business performance.' The spokesperson noted that women comprise over 40% of Sieg's senior leadership team and praised his ability to 'attract, retain and promote industry-leading talent.' But the mass exodus of longtime executives tells a different story about life under Sieg's regime. The wealth division has undergone massive layoffs as part of Fraser's plan to eliminate 20,000 positions across the bank. 7 A spokesperson for Citi told Reuters that 'we look forward to Andy continuing to drive strong business performance.' Christopher Sadowski Senior managers grew alarmed at the intensity of complaints about Sieg's behavior during the restructuring, sources said. Whether Fraser will take action against her handpicked lieutenant or stand by him despite the damaging allegations remains unclear as the investigation's conclusions stay buried. The Post has sought comment from Sieg, Fraser, Citi, Paul Weiss and Liu.

Microsoft's AI Leader Is Begging You to Stop Treating AI Like Humans
Microsoft AI's CEO Mustafa Suleyman is clear: AI is not human and does not possess a truly human consciousness. But the warp-speed advancement of generative AI is making that harder and harder to recognize. The consequences are potentially disastrous, he wrote Tuesday in an essay on his personal blog. Suleyman's 4,600-word treatise is a timely reaction to a growing phenomenon of AI users ascribing human-like qualities of consciousness to AI tools. It's not an unreasonable reaction; it's human nature for us to imagine there is a mind or human behind language, as one AI expert and linguist explained to me. But advancements in AI capabilities have allowed people to use chatbots not only as search engines or research tools, but as therapists, friends and romantic partners. These AI companions are a kind of "seemingly conscious AI," a term Suleyman uses to define AI that can convince you it's "a new kind of 'person.'" With that come a lot of questions and potential dangers. Suleyman takes care at the beginning of the essay to highlight that these are his personal thoughts, meaning they aren't an official position of Microsoft, and that his opinions could evolve over time. But getting insight from one of the leaders of a tech giant leading the AI revolution is a window into the future of these tools and how our relationship to them might change. He warns that while AI isn't human, the societal impacts of the technology are immediate and pressing. Watch this: How You Talk to ChatGPT Matters. Here's Why 04:12 Dangers of "Seemingly Conscious AI" Human consciousness is hard to define. But many of the traits Suleyman describes as in defining consciousness can be seen in AI technology: the ability to express oneself in natural language, personality, memory, goal setting and planning, for example. This is something we can easily see with the rise of agentic AI in particular: If an AI can independently plan for and complete a task by pulling from its memory and datasets, and then expressing its results in an easy-to-read, fun way, that feels like a very human-like process even though it isn't. And if something feels human, we are generally inclined to give it some autonomy and rights. Suleyman wants us and AI companies to nip this idea in the bud now. The idea of "model welfare" could "exacerbate delusions, create yet more dependence-related problems, prey on our psychological vulnerabilities, introduce new dimensions of polarization, complicate existing struggles for rights and create a huge new category error for society," he writes. There is a heartbreakingly large number of examples to point to of the devastating consequences. Many stories and lawsuits have emerged from chatbot therapists dispensing bad and dangerous advice, including encouraging self-harm and suicide. The risks are especially potent for children and teenagers. Meta's AI guidelines recently came under fire for allowing "sensual" chats with kids, and has been the target of much concern and a lawsuit from a Florida mom alleging the platform is responsible for her teen's suicide. We've also learning more about how our brains work when we're using AI and how often people are using it. Read more: AI Data Centers Are Coming for Your Land, Water and Power Suleyman argues we should protect the well-being and rights of existing humans today, along with the animals and the environment. In what he calls "a world already roiling with polarized arguments over identity and rights," debate over seemingly conscious AI and AI's potential humanity "will add a chaotic new axis of division" in society. In terms of practical next steps, Suleyman advocates for additional research into how people interact with AI. He also calls on AI companies to explicitly say and not encourage people to think that their AI products are conscious, along with more open sharing of the design principles and guardrails that are effective at deterring problematic AI use cases. He says that his team at Microsoft will be building AI in this proactive way, but doesn't provide any specifics.

Silicon Valley startup Tensor unveils a personal ‘RoboCar'
This story was originally published on Automotive Dive. To receive daily news and insights, subscribe to our free daily Automotive Dive newsletter. Dive Brief: Tensor, a Silicon Valley-based autonomous driving startup, has unveiled a personal electric robotaxi called the 'Tensor RoboCar' that it aims to start delivering to customers in the second half of 2026, the company announced in an Aug. 13 press release. The vehicle was built from the ground up for SAE Level-4 autonomy in partnership with leading Tier 1 suppliers and electric vehicle maker VinFast. VinFast and Tensor plan to scale production at the automaker's assembly plant in Vietnam, which includes stamping, welding, painting and final assembly of the vehicle. The RoboCar will be available in select global markets in the U.S., Europe and the UAE, per the release. Dive Insight: While ride-share operators Waymo, Uber and EV maker Tesla are racing to deploy fleets of commercial robotaxis, Tensor becomes one of the first companies with plans to sell one directly to consumers for use as their personal autonomous vehicle. 'With Tensor, we're introducing the world's first personal RoboCar, ushering in the era of AI defined vehicles,' said Tensor Chief Marketing Officer Amy Luca, in the release. 'This isn't a car as we know it.' Switch Auto Insurance and Save Today! Great Rates and Award-Winning Service The Insurance Savings You Expect Affordable Auto Insurance, Customized for You The Tensor RoboCar is equipped with over 100 sensors to support Level 4 autonomous driving without human intervention. But the vehicle can still be driven as needed. The vehicle's steering wheel folds away and its pedals retract when not in use, which Tensor says is the world's first such feature. In areas where Level 4 autonomy is not supported, a driver can take the wheel or switch to 'assisted driving' mode for a smooth handoff. The RoboCar's comprehensive sensor suite includes 37 cameras, five lidars, 11 radars, 22 microphones, 10 ultrasonic sensors, 16 collision detectors, eight water-level detectors, four tire-pressure sensors, a smoke detector, triple-channel 5G network connectivity and other tech. Tensor said its RoboCar sets a benchmark in automotive sensing with the 'world's most vertically integrated Level 4 autonomy stack.' The system is powered by an onboard Nvidia processor. To further ensure safe driverless operation, the vehicle is built with a fully redundant electrical and electronic architecture across power, communications, and motion control, including its drive-by-wire system, which Tensor says ensures fail-safe operation. The robotaxi also features brake-by-wire, steer-by-wire and four-wheel steering. Level 4 autonomous driving powered by AI Tensor's approach to autonomous driving is built on what it refers to as the 'Tensor Foundation Model,' which is entirely data-driven as opposed to rule-based systems. It's based on a transformer architecture that allows the vehicle to 'learn complex patterns' based on its environment, according to the release. The technology stack includes 'dual-system AI,' which the company says 'mirrors human cognition' for decision making. All of the vehicle's AV's perception, prediction, and motion planning systems were fine-tuned using real-world and simulated datasets. One part of the dual AI system is designed to deliver quick vehicle responses through imitation learning from data collected from expert drivers. The other uses a multimodal visual language model to reason through rare edge cases, which have been known to trip up Waymo vehicles leaving them stuck. The VLM is trained on both proprietary and large-scale internet visual data, including images and videos, to help ensure the vehicle can adapt to any driving environment. Other RoboCar features designed to improve the ownership experience are vehicle self-diagnostics, automatic over-the-air software updates, autonomous parking and charging, and even protective sensor covers to protect the sensors from pollen, dust, sand, or debris while not in use. The vehicle's sensor-cleaning systems have dedicated wipers and nozzles to ensure the units remain free from dirt and road grime that could degrade their performance. To address data privacy concerns of connecting to the cloud, Tensor's RoboCar stores all user location, preferences and other data locally on the vehicle for a high level of security. But users can access their data via an encrypted smartphone app or onboard interface, making data impossible to track, extract or compromise, according to Tensor. Building software-defined vehicles at scale remains a challenge for automakers, so as a new startup, Tensor turned to industry partners to develop its RoboCar. The company said the vehicle's advanced features are a direct result of its close collaboration with Tier 1 suppliers, including Autoliv, ZF, Bosch, Continental, Veoneer and others. Tensor also partnered with chipmakers Nvidia, AMD, NXP, Texas Instruments, Qualcomm and Samsung. Tensor also said it's working with global insurance broker and risk advisor Marsh to offer customers what it calls 'the world's first insurance policy for RoboCars.' Tensor did not share any information about pricing for its RoboCar in the release. Recommended Reading Waymo, Magna to jointly build robotaxis at new Arizona factory
