AegisAI, founded by former Google security execs, lands $36M to stop AI-driven spear phishing

Hackers are increasingly using AI to launch attacks on a massive scale, with email emerging as a primary target. AI can quickly aggregate personal information — such as information about co-workers, active projects, and recent travel itineraries — allowing bad actors to instantly craft convincing messages that look authentic.

Last year, former Google security executives Cy Khormaee and Ryan Luo, who previously worked on developing safe browsing technology and reCAPTCHA, teamed up to launch AegisAI, a startup that uses AI agents to stomp out these threats, known as spear phishing.

With a decade of experience preventing email hacks, the AegisAI co-founders realized that existing rule-based systems for preventing hacks — relying on “if-then” logic — are too slow and limited to catching AI-crafted malicious emails. So they developed AI agents that quickly analyze each message as a human would, paying attention to small anomalies that even the most elaborate checklist wouldn’t catch.

Less than a year after its launch, AegisAI says its tech has been adopted by dozens of customers, including crypto payments company Mesh, AI startup LangChain, and privacy compliance platform Lokker. That demand has just helped AegisAI raise a $36 million Series A led by Battery Ventures, with participation from existing backers Accel and Foundation Capital. The fresh funding brings the startup’s total capital to $49 million.

“AI-powered attacks bypass existing controls more than half the time now, which means they’re almost twice as effective as they used to be,” Khormaee told TechCrunch. “They’ve researched you, they understand everything about you, and they’re targeting attacks that are perfectly bespoke to you.”

Khormaee claims that AegisAI’s agents can spot threats traditional email security systems may miss entirely. For instance, the startup’s AI can catch malicious PDF attachments that look legitimate at first, including ones with built-in passwords and CAPTCHA, which are often used to fool standard spam filters.

When Dharmesh Thakker, general partner at Battery Ventures, noticed an increase in email attacks, he set out to invest in a startup that could defend against AI with AI, one aiming to replace legacy email security tools with agentic-driven defense.

“The bad guys are using email to attack us using AI at a much faster pace than we can keep up with,” Thakker told TechCrunch. “Defending against that is going to be a number one priority for a lot of companies.”

AegisAI isn’t the only startup using AI to analyze the context of every incoming email to detect fraud and impersonation attempts. Lightspeed-backed Ocean is also trying to displace established vendors like Proofpoint and Mimecast, along with newer players like Abnormal Security.

However, given that AegisAI is led by experts who helped secure Gmail, the most popular email system in the world, Thakker believes the startup has the best shot at becoming the leading new hack-prevention company.

While AegisAI is starting with email, the startup has its sights on eventually expanding to other areas of defense, such as data security. “The core idea of building customized, highly advanced agents that can do investigations is going to [determine] who becomes the next dominant security company,” Khormaee said.

Google’s Gemini nears billion-user milestone

Google is about to add another name to its long list of products with more than a billion users, a list that already includes Search, Gmail, Drive, Android, YouTube, and Chrome. The company said during its Q2 2026 call that the AI assistant Gemini now has over 950 million monthly users.

The company noted that Gemini users have tripled from last year. Earlier, in February, it said that the Gemini app crossed 750 million monthly active users. With this growth, Google’s assistant is in line to compete more closely with OpenAI’s ChatGPT, which hit 1 billion monthly active users in June.

“Users love new agentic features like Daily Brief and our personalized agent, Gemini Spark, which is now available in the U.S. and internationally. We’ve been shipping helpful new features like this at an incredible pace,” Alphabet CEO Sundar Pichai said during the call.

Apart from users on Android, the Gemini app has found a strong user base on iOS with launches like the Nano Banana image generation model. According to Appfigures, the app has been downloaded over 137 million times on iOS in the last 12 months.

In its latest “State of AI” report, the analytics firm Sensor Tower noted that ChatGPT’s market share among AI assistants fell below 50% for the first time. The report, which looked at H1 2026, also noted that Gemini’s share rose to 27.7%.

Many people already use AI assistant apps as a substitute for search. However, Google reported that its search vertical is going strong, partially thanks to the AI-centric overhaul. During this quarter, its Q&A-style AI mode crossed 1 billion users. The company said that it is driving “an incremental increase” in search queries. Google also noted that through hardware engineering, it has reduced the cost of AI mode for the company, despite introducing new models and features.

Google will now let you sign in to your account with a selfie video

Google is adding a selfie video option as a new way for users to log in to their accounts, the company announced on Thursday, joining a growing wave of tech companies betting that biometrics and not passwords are the future of identity verification online. The tech giant says selfie videos give users more options to sign in if they’re ever locked out or don’t have access to their usual phone or computer.

Users set up a selfie video by looking at their device’s camera and completing a few guided head movements — think turning right or left or nodding — to capture multiple angles of their face. If a user is having trouble signing in later, they can take another selfie video to get back into their account, and Google will then compare the new video to the one used at setup to confirm it’s the correct person.

The bigger challenge Google is trying to solve is proving a real human, not a bot or a doctored video, is on the other side of the camera. “When you use a selfie to sign in, we use multiple layers of security to help prevent impersonation attempts like fake photos and videos (i.e., deep fakes),” Google wrote in the blog post. “For example, we match your video against your saved selfie and require you to perform simple movements to prove it’s a live video. We also use our standard security practices to detect and help prevent suspicious sign-in attempts.”

This isn’t just about individual accounts, though. As AI-generated video gets more convincing, “liveness” checks are becoming a baseline requirement for any company handling logins, payments, or sensitive data.

Although the new option could help protect accounts against fraud and help users recover locked accounts, it also raises concerns around user privacy and biometric data collection, an area regulators have increasingly scrutinized as more companies build products around facial and voice data.

Google says selfie videos are stored securely using encryption and remain protected even when they’re not being used, and that users can choose to delete the videos from their Google account at any time.

Meta launched a new AI optimism ad set to a song about human extinction

Meta’s newest advertisement begins with a black-and-white shot of an eye, showing us what someone sees as they read countless panicked headlines about how AI is going to take our jobs, isolate us, and spark a global crisis.

“Some people will have you believe AI is going to make us feel less connected. That it’s going to leave us behind,” a voiceover says. “We couldn’t disagree more.”

Suddenly, the video shifts to color, and shows a cycle of different people opening their eyes and smiling. Then, we see a couple dancing on a rooftop, pointing at a rainbow; a group of teens swimming in a lake; a child frolicking in a field; friends embracing after time apart.

“Call us optimists. Call us dreamers. Call us whatever the hell you want. But we’re betting on people, and we like those odds,” the voiceover says. “The future is for everyone.”

That’s a nice sentiment — pretty convenient for a company betting hundreds of billions of dollars that AI will revolutionize humanity. But the strangest part of the advertisement is not that we’re watching these happy moments play out via Instagram posts. It’s that the soundtrack to the ad is the David Bowie song “Five Years.”

If you are not familiar with this song, I urge you to give it a listen, read the lyrics, and think about what it is trying to say. It seems clear to me, but I studied poetry in college, so as a control for this experiment, I asked my brother — a blockchain analyst who loves Claude Code and does not read for fun — if he could tell me what the song is about.

“I thought climate change at first, then zombie apocalypse, then an asteroid hitting the earth,” he told me. He is correct. It is a song about the human race panicking after learning they will die in a mass-extinction event in five years.

If you’re not familiar with Bowie’s music, this track might sound happy and inspiring, matching the ad’s upbeat tone. The part of the song that is used for the advertisement was probably chosen because it uses the word “people” over and over again, and without the context of the song, it’s not clear what it’s about.

But if we look at the lines directly preceding this section:

News had just come over
We had five years left to cry in
News guy wept and told us
Earth was really dying
Cried so much his face was wet
Then I knew he was not lying

We “had five years left to cry in” and the “earth was really dying.” It’s pretty bleak.

It is not reassuring to convince people that AI is going to make the world better while playing a song about the end of the world, and yet, this contradictory musical choice seems to have sailed right past everyone at Meta, including CEO Mark Zuckerberg.

“Meta has always believed in giving people the power to share, connect, and shape your world in the ways you want,” he wrote alongside the video. “As we enter this next wave with AI, we continue to believe the future is for everyone. We’re focused on giving every person the tools to reach your full potential and making sure the benefits of technology are distributed to everyone.”

Then again, tech leaders are not known for their literary analysis skills. Meta’s Oculus used to give new hires copies of the science fiction novel “Ready Player One,” which is set in a dystopia in which a tech company making virtual reality products becomes overly powerful and evil. OpenAI CEO Sam Altman has directly cited inspiration from the movie “Her,” which warns us about what can go wrong when we use AI for emotional support. Palantir, a company that builds AI surveillance systems for the government, is named after Palantir, a seeing stone from the “Lord of the Rings” franchise that the Dark Lord uses to spy on his enemies. Elon Musk is currently throwing a fit about the “accuracy” of Christopher Nolan’s blockbuster adaptation of “The Odyssey,” a story with such realistic elements as sea monsters, magic, and divine intervention. These guys make a great argument for the value of studying the humanities.

Meta isn’t alone in its recent promotional foibles. Instead of racing to build AGI, the top AI companies seem to be fighting over who can make the creepiest advertisement. A few weeks ago, Anthropic released an eerie video of its own. As my colleague Lucas Ropek described it:

The ad begins with a video of a burning house (not exactly a heartwarming start) before pivoting to a series of still images. These images include a crowd of people being surveilled by facial recognition, a homeless person sleeping on the street, rows upon rows of tombstones in a cemetery, and what appears to be a group of laborers toiling in a mine where (presumably) raw materials for smartphones are being dug up.

Meanwhile, a voice-over track features different people asking questions like “Can AI be trusted?” and “Who’s gonna hit the brakes if we need to?”

Anthropic is trying to convince us that it understands the risks AI poses to society, and therefore, this is the company that people can trust to develop AI responsibly. The message it actually conveys feels closer to the mood of Bowie’s “Five Years.”

OpenAI CEO Sam Altman responded to the Anthropic ad, “I thought this was satire, kept looking for the handle to be spelled c1audeai or something.”

As these companies spar to control the public perception of AI, their efforts don’t seem to be making much progress. A recent Pew survey found that only 16% of Americans think that AI’s impact on society over the next 20 years will be positive, and 40% believe it will have a negative impact. Better luck next time, Meta.
