As Greece’s cost of living pressures continue to weigh on families, Greek-American George Machairakis found himself hearing the same concerns from friends and family back home about rising grocery bills, fuel prices, and everyday living expenses. They were becoming more and more difficult to manage.
Originally from Sitia, Crete, and based in Boston for more than two decades, Machairakis told Greek Reporter that those conversations made the issue deeply personal and convinced him that consumers needed an easier way to compare prices. He went on to create AgoraSmart, a free platform covering everything from supermarkets, fuel, and pharmaceuticals to electricity, telecommunications, and banking among other essential expenses such as medical coverage.
A Greek-American take on everyday spending
Living in Boston while developing a service for consumers in Greece gave Machairakis a perspective on two very different approaches to spending. “Americans, who compare less, have endless tools to do it—cashback apps, price trackers, comparison sites for everything,” Machairakis told Greek Reporter. “Greeks, who genuinely need to compare after years of price increases squeezing household budgets, had almost nothing built for their everyday basket.”
In Greece, he said, consumers tend to pay close attention to individual prices even though the information needed to compare everyday expenses is scattered across stores, websites, and providers. “My family compared prices with a pencil on the back of a receipt,” he said. “I wanted to give that instinct a modern tool.”
Machairakis also decided early on that AgoraSmart would not focus solely on groceries. “A family in Crete doesn’t feel ‘supermarket inflation’ and ‘fuel inflation’ separately—it feels one squeezed monthly budget,” he said. That thinking motivated him to come up with something that integrated all essential aspects of everyday consumption.
“Trust is the real product; the categories are just rooms in the same house,” Machairakis stated.
What Greece’s cost of living looks like in the data
As AgoraSmart’s database expanded, Machairakis said some of the price differences he encountered surprised him. According to his analysis of the platform’s data, identical products can sometimes vary in price by 25 to 40 percent between supermarket chains in the same area. In some household and cleaning categories, he said, the gap has approached 45 percent. Those figures are based on AgoraSmart’s own data and have not been independently verified by Greek Reporter.
Machairakis also pointed to shrinkflation, the practice of reducing the quantity or size of a product without a corresponding reduction in price. Such changes can make increases in the cost per unit more difficult for shoppers to notice. Another issue emerged when prices listed online did not match those in the actual stores. “The e-shop is not always the truth of what you’ll pay at the register,” he said.
That finding influenced how AgoraSmart handles conflicting data. Machairakis said photographed shelf labels and printed receipts can be treated as stronger evidence than an online listing when the two differ. For a price-comparison service, he argues, that distinction matters because the information is useful only if it closely reflects what consumers actually encounter when they make a purchase.
How a Greek-American is tackling the cost of living data challenge in Greece
Maintaining a large database is one challenge. Keeping it current and reliable is another. Machairakis said AgoraSmart relies on multiple verification methods depending on the category. For electricity, telecommunications, insurance, and banking, for instance, data on prices is drawn from official provider sources and reviewed periodically. Grocery prices are cross-checked using receipts, shelf photographs, and online sources. Promotional prices are not recorded as regular prices, he said, while conflicting information is handled conservatively rather than resolved through estimates.
“When two credible sources disagree, we keep the older price rather than guess,” Machairakis said. “Nothing is ever invented to fill a gap; a missing price is more honest than a wrong one.” Furthermore, fuel data is anchored to official market information and supplemented with evidence from individual stations, according to Machairakis. Consumers can also report price changes through the platform. Those submissions are reviewed before the database is updated.
As AgoraSmart grows, Machairakis hopes direct partnerships with supermarket chains and other providers will offer another source of timely information. It is his belief that accuracy remains more important than simply presenting the largest possible database. “A comparison app is worthless the first time a user stands at a shelf and sees a different number than the app showed,” he told Greek Reporter.
From the restaurant business to building with AI
Machairakis did not enter the project through a conventional career in software development. “I’m a restaurant guy, not a programmer,” he said. After twenty-three years in the restaurant business, he began using artificial intelligence tools to help design, build, and operate AgoraSmart while resuming his regular work.
“What surprised me most is what building looks like in 2026,” Machairakis said. “I’m not a programmer, but working with AI as a partner, I designed, built, and now run a platform with more than 11,600 products across eleven supermarket chains, 6,500 fuel stations, and nine utility and insurance categories—solo, from a kitchen table, between Boston and my family’s home in Sitia, Crete.”
For Machairakis, AI lowered a technical barrier that might once have required a larger development team. Yet he said the harder part was establishing standards for the information itself and refusing to fill gaps when reliable data was unavailable. “The discipline was harder than the code,” he said.
The experience also changed his view of who can build technology, he admits. “It taught me that the barrier today isn’t technical skill; it’s whether you understand a real problem deeply and care enough to be accurate about it.”
What comes next for the Greek-American behind Greece’s cost of living tool?
The larger challenge will be maintaining accuracy as the platform expands. Adding more products, locations, and services can make AgoraSmart more useful, but it also increases the volume of information that must be verified and updated. The project reflects a broader shift in technology, as well, as AI tools make it increasingly feasible for people without traditional programming backgrounds to turn firsthand knowledge of a problem into a functioning digital product.
For Machairakis, the goal remains straightforward—helping households in Greece better navigate the rising cost of everyday life. As AgoraSmart grows, earning and maintaining consumers’ trust will be the true measure of its success.
