Giorgos Zacharia has spent a career making choice less of a chore

Giorgos Zacharia’s career contains enough mathematics to frighten a dinner party. Two bachelor’s degrees, a master’s, a doctorate, and an early record in mathematical Olympiads. Yet much of his working life concerns a rather sociable ambition: helping somebody make up their mind. Which flight? Which insurer? Which result deserves a second look? The equations have had to earn their place in ordinary life.

Today he is co-founder and co-CEO of Insurify, sharing the job with his wife, Snejina Zacharia. Before that came KAYAK, where he moved through scientific, product, and technology leadership to become president. Read those titles in sequence and they suggest a journey away from research. Look at the work itself and the progression seems more intimate: a continuing investigation into what people need before they can choose.

A medal before the marketplace

There is a useful place to begin before the executive appointments. In 1992, Zacharia represented Cyprus at the International Mathematical Olympiad and won a bronze medal. The official results record fourteen points across six problems. A medal is a neat credential; the score sheet is more revealing. It is a record of particular problems tackled under particular constraints, rather than a general certificate of cleverness.

He arrived in the United States in 1993 to study at MIT, supported by a Fulbright scholarship. His undergraduate subjects were mathematics and computer science, with an economics minor alongside the latter. A master’s in media arts and sciences followed. His doctorate in electrical engineering and computer science was completed in February 2009. Four degrees give an institution several opportunities to claim you as an alumnus.

At MIT, his work included reputation mechanisms, listed alongside projects called Kasbah and PDA@Shop. His later doctoral research concerned regularized ranking and manifold learning. These are technical subjects with a familiar human question nearby: when presented with an abundance of possibilities, how should we put them in an order that helps?

Open Ratings gave that question a commercial setting. Zacharia co-founded the supplier risk business and served as its CTO and chief scientist before joining KAYAK. An industrial buyer needs to judge the company behind a promise, just as a traveler needs to judge the journey behind a fare. The decisions differ enormously. In both, a tidy display is only useful if the information beneath it deserves attention.

The holiday, reorganized

He joined KAYAK as chief scientist in 2008. By 2013 he was chief product officer, and in 2014 he became CTO. That progression placed him close to the awkward meeting between what a system knows and what a customer can understand. Travel search offers plenty of opportunities for that meeting to go badly. A page can contain a great many answers while remaining remarkably unhelpful.

One experiment in September 2014 offered travelers a Gantt chart. Departure and return segments appeared separately, giving users another way to assemble a trip. It was an amusing migration of an office tool into the holiday business. Zacharia’s explanation included a joke about people still using Microsoft Project, but the principle underneath was practical: try a presentation, observe its use, and remove what people do not want.

“We continually experiment with our user interface, testing new designs and removing less popular features every week.”

There were questions of credibility as well as arrangement. In 2013, KAYAK introduced hotel reviews from verified travelers, bringing in feedback from booking services and reputation analysis from TrustYou. Zacharia explained the value of hearing from people who had actually stayed. A star beside a hotel is pleasantly compact. Establishing why anyone should believe it requires a little more work.

By 2016, he oversaw an engineering team of about 350 within a company of roughly 500 employees. His responsibility had become organizational as well as mathematical. Search quality depended on people building and maintaining the product, with all the coordination that implies. A successful comparison page is a small public surface resting on a considerable amount of private labor.

His account of KAYAK’s culture adds a useful wrinkle to the technical résumé. He described a preference for small teams and short meetings, with standing meeting rooms helping keep discussions practical. Customer feedback could reach employees directly, giving engineers a chance to encounter recurring complaints. It is an appealingly unsentimental arrangement. An inconvenience repeatedly delivered to the person who can fix it may eventually become harder to tolerate than the repair. In that version of management, proximity does some of the work that a more elaborate reporting system might promise. The person building the experience gets to hear what using it feels like.

A household problem becomes a company

Insurify began with Snejina’s experience of shopping for car insurance after a minor accident raised her premium. Phone calls and an overflowing inbox failed to produce a satisfactory comparison. While attending MIT Sloan, she saw room for a service that would make the process easier. In 2013, she founded Insurify with Giorgos and Tod Kiryazov. The original irritation was domestic; the resulting work would occupy years.

That distinction matters in telling Giorgos’s story. His co-founder title dates to 2013, while his appointment as co-CEO was announced in March 2025. Between those dates, he continued his KAYAK career, becoming president in 2020. A founding relationship and an operating appointment can belong to different chapters, even when a company has long been part of the household conversation.

The company itself developed through stages. Online comparison launched in 2016, an in-house agency followed in 2020, and Insurify acquired Compare.com in 2023. Each step altered what the business could do for a customer. Presenting options, helping complete a purchase, and maintaining an insurance relationship demand different kinds of work. The familiar phrase “comparison site” can make all that sound deceptively stationary.

In the co-CEO arrangement, Giorgos’s announced focus was innovation and marketing. He and Snejina would share responsibility for the company, product vision, and growth strategy. There is a certain economy in that pairing: one brief concerns how the service improves; the other concerns how people come to use it. A useful product still needs to find its way into someone’s day.

He has spoken with humor about business occupying the family dinner table alongside homework. There is no need to imagine a pristine partition between founder and parent here. Insurify had been in the family’s vocabulary for years before the co-CEO announcement. The public job description made formal a partnership whose history was already considerably longer than its latest title.

The next interface needs the fine print

By 2026, another participant had entered the shopping conversation: the AI agent. In March, Giorgos described Insurify’s initial ChatGPT integration as offering estimated prices, with people directed to Insurify for full quotes. He discussed privacy and security concerns around personal information. The distinction between an estimate and a quote is easy to flatten in a demonstration; it becomes rather consequential when someone is preparing to buy.

In August, Insurify appointed Jake Bouvrie as its first chief AI officer. Zacharia highlighted a relationship reaching back to the same MIT lab and forward through KAYAK. Bouvrie became the twenty-seventh KAYAK alumnus at Insurify. For all the discussion of new technology, this part of the story has an old professional mechanism: people who know one another’s work choosing to work together again.

September brought a sharper illustration of Zacharia’s priorities. Insurify blocked Meta’s Muse agent, arguing that it stripped carrier quotes of information shoppers needed. The disputed omissions included coverage limits, deductibles, and eligibility. His objection went directly to what a comparison should preserve. A cheaper premium becomes a poor guide when the things it buys have slipped out of view.

“A quote without its context is not a fair comparison. It is a number.”

The next month, Insurify joined Sierra and other technology companies as an early design partner in the proposed Personal Agent Protocol, known as Poppy. Its contribution concerns consent, coverage transparency, and protections for carriers. The protocol remains a proposal under development. The practical questions are already present: who authorized an agent, what can it access, and what information must accompany the result?

A return ticket to Cyprus

Cambridge is Zacharia’s professional base, but Cyprus remains an active connection. He served as a judge for the Cyprus Entrepreneurship Competition in 2021. In April 2025, the Capital Link Cyprus Business Forum listed him as an Insurify co-founder and member of Cyprus’ AI Taskforce, on a panel about the country’s role as a technology gateway.

Those appearances put different parts of his experience in the same room. Research, product development, and running a marketplace each offer a different answer to what an emerging company needs. A panel does not build a business for its audience. It can, however, put someone who has wrestled with the practicalities within conversational distance of someone just beginning.

Across that career, the recurring object is the decision in front of the customer. The supplier has a history. The flight has conditions. The policy has coverage. Zacharia’s latest work asks how those details survive a new shopping interface. After four MIT degrees and a succession of executive titles, the obligation is still refreshingly concrete: help people understand what they are choosing before they commit.
