A $700M Nvidia-backed AI search startup is hiring ‘rebellious’ engineers, its CEO told us

An Nvidia-backed startup is looking for “rebellious” engineers to help rebuild search for the AI era.

Exa, which builds search infrastructure for AI applications, said it is opening a Singapore office on Monday as part of its push into Asia-Pacific. Exa has only a handful of staff in Asia-Pacific, and plans to hire up to 10 engineers across backend, infrastructure, and product roles in the coming months.

In an exclusive interview with Business Insider, CEO Will Byrk said he is hiring “rebellious” engineers.

“Someone who doesn’t care about the status quo, how things were done in the past, can think from first principles about everything — that’s really important,” he said.

Search systems built for AI are still new, and they require rethinking how search works because humans and AI behave differently, he added.

“I don’t believe it when people say you can’t do something. So I think we want engineers who feel the same way,” Byrk said.

Byrk also said Exa prioritizes candidates’ values above all else, and the company is open to hiring junior and senior engineers.

“Do they really have passion for building search or building large-scale systems?” he said, adding that experience is “not as important.”

To assess candidates for their character, Exa flies them to San Francisco to work with the team for one to two days. Exa has about 80 employees globally and is actively hiring in San Francisco, Zurich, and Singapore.

“That allows us to really see what a person’s like, because you don’t just get to see their output on a real project, but you also, you know, eat with them at lunch and dinner,” he said. “You really get to know a person.”

Byrk added that the best engineers should move fast and use AI tools effectively. Most of the company’s code is written by AI, he said.

Expansion into Singapore

Exa raised $85 million in a Series B round led by Benchmark in September at a $700 million valuation. Investors include Lightspeed, YCombinator, and NVentures, Nvidia’s venture capital arm.

The company, founded in 2021, said it serves web search to thousands of customers, including AI startups such as Cursor, as well as private equity and consulting firms.

“The number of searches from AIs are going to exceed the number of humans,” Byrk told Business Insider. “The whole world of search is shifting.”

Byrk said the Singapore office will serve as a “massive scale infrastructure,” including data pipelines and crawling infrastructure to gather and process information across the internet.

“Singapore has some of the best engineering talent in the world,” Byrk said. “People are really smart, and they have a lot of hustle.”

A-Google-VP-explains-why-ads-make-sense-in-AI.jpeg

A Google VP explains why ads make sense in AI search but not Gemini — yet

Marketers champing at the bit for AI chatbots to become the next major ad surface may have to suppress their appetites a little longer.

With Google’s Gemini surging in popularity, speculation has been bubbling in the ad industry that the app might be on the cusp of introducing ads to capitalize on the moment — and help offset the hefty AI infrastructure costs.

Not so, according to Google’s VP of global ads, Dan Taylor. In an interview with Business Insider this week, Taylor reaffirmed there are “no plans for ads in the Gemini app.”

Instead, the ads team is prioritizing ad placements within AI search. Google began introducing ads to AI Overviews — the natural language summaries of search results that appear at the top of its search engine results page — in 2024. Last year, it brought ads to AI Mode, its AI chatbot that appears on search pages, which enables users to conduct more in-depth research and ask follow-up questions.

“Search and Gemini are complementary tools with different roles,” Taylor said.

“While they both use AI, search is where you go for information on the web, and Gemini is your AI assistant,” he said. “Search is helping you discover new information, which can include commercial interests like new products or services. We see Gemini as helping you create, analyze, and complete that.”

From an advertising perspective, Google has over 25 years of experience with search ads. Monetizing AI assistants is a relatively new, uncharted territory with numerous questions to consider.

Here are a few:

  • Where and when should an ad show up?
  • What would these ads look like, and how should companies think about charging for them?
  • How can an AI chatbot balance commercial interests while also ensuring users feel they are getting accurate and objective answers?
  • Could the introduction of ads alienate users in a competitive landscape where apps like Gemini are fighting for supremacy against the likes of OpenAI’s ChatGPT, Microsoft’s Copilot, and Anthropic’s Claude?

A first-mover disadvantage?

Ads might feel inevitable as tech giants invest billions of dollars into their AI infrastructures. However, AI companies are aware that making the first move could be perceived as a degradation of their products and cause users to jump ship.

Google’s success in leveraging AI to create financial gains from its existing search product and advertising platform is one advantage it has over arch-rival OpenAI, which is under pressure to demonstrate a path to profitability. It potentially gives Google more leeway to wait before introducing an ad model to Gemini.

Stratechery tech analyst Ben Thompson said in a recent interview on the tech news show TBPN that OpenAI delaying ads in ChatGPT “risks the entire company.”

“They could have launched the world’s crappiest ads in 2023. By today, in 2026, they would be good,” Thompson said. “Now, they’re going to have to launch ads, they’re going to suck, and people are going to be like, ‘This sucks, I’ll just go to Gemini.'”

The rivalry between Google and OpenAI intensified late last year when Google released its Gemini 3 AI model, which received rave reviews. OpenAI CEO Sam Altman responded by issuing a “code red,” telling teams to redirect resources from newer projects, including a yet-to-be-released advertising program, to prioritize improving ChatGPT’s performance.

Gemini had 650 million monthly active users, Alphabet, Google’s parent company, said in its latest quarterly earnings report in October. OpenAI said in October that ChatGPT had 800 million weekly users.

What Google has learned from ads in AI search so far

Taylor said that more than 80% of Google’s advertisers are currently using some form of AI-powered search functionality. That’s largely through the adoption of tools like AI Max for Search and Performance Max, where Google’s AI algorithm automatically chooses which ad creatives a campaign should run and where to place those ads.

Advertisers can’t yet specifically choose to run ads within AI Mode or AI Overviews. Instead, the algorithm makes the decision to place them there based on targeting variables like location, demographics, keywords, and topics.

“We don’t have any plans to enable buying separately at this phase,” Taylor said.

Taylor said AI Overviews have notched up more than 2 billion monthly active users, and that people are clicking and engaging with AI Overview ads “at about the same rate” as traditional search ads.

Google’s testing of ads in AI Mode isn’t as far along and presents more challenges when trying to convert the traditional search ads playbook for the AI era. Users have longer back-and-forth conversations in AI Mode, and ads shown too early can feel “intrusive” and create “a trust problem,” Taylor said. A newbie runner seeking helpful information about how to prepare their body for a marathon later in the year might not be ready straight away for ads featuring performance running shoes, for example, he added.

This month, Google said it had begun testing a new ad format called Direct Offers, which will let advertisers present personalized discounts to shoppers who are about to make a purchase within AI Mode. Taylor said Google is only working with a specific set of advertisers on the Direct Offers pilot and didn’t have more information about when it might become broadly available.

Direct Offers was one of several announcements Google made regarding new AI-shopping experiences. New products included a forthcoming checkout function that will let shoppers complete their purchases inside AI Mode and the Gemini app.

Judge orders Google to rebid for default search deals every year in a major antitrust blow

  • A federal judge ordered Google to limit default search and AI app contracts to one year.
  • The ruling follows a 2024 finding that Google illegally monopolized online search markets.
  • The decision aims to boost competition from rivals in search apps and generative AI.

A judge opened the door to upending Google’s dominance as the default search on your phone.

On Friday, a federal judge ordered Google to limit all default search and AI app contracts to one year, a setback for the long-term deals that have helped cement the company’s dominance on billions of devices.

The ruling, detailed in a December 2025 judgment, requires Alphabet’s Google to renegotiate every default-placement agreement annually, including lucrative deals with Apple’s iPhone and manufacturers like Samsung.

Judge Amit Mehta of the US District Court of the District of Columbia said the “hard-and-fast termination requirement after one year” is necessary to enforce antitrust relief after his landmark 2024 finding that Google illegally monopolized online search and search advertising.

The decision aims to open the door for rivals, especially fast-moving generative AI companies, to compete for default spots that have historically been held for years at a time. It builds on a separate September order requiring Google to share some of the data behind its search rankings with competitors.

While Google can still pay device makers for default placement, the annual renegotiation rule sharply restricts its ability to secure long-term control over the search market.

Google and the Justice Department did not immediately respond to requests for comment.
