The Messenger Who Became the Merchant
There's a detail that tells you everything about Stefanos Loukakos: before he ran Google's entire Greek operation, before he became the face of Facebook Messenger for businesses across Europe, he was the CEO of Hellas Online - a broadband operator fighting for market share in Athens. He has always been the person who shows up where communication and commerce collide.
Born in Greece, he assembled a resume that cuts across continents and industries in a way that no one plots in advance. Quantitative analyst at Societe Generale in 1999. Senior associate at HSBC. Director of Finance and Strategy at Deutsche Telekom. Each role a rung on the same ladder: understanding how networks move money and messages. Then he ran an ISP. Then he ran Google Greece. Then Facebook called.
At Facebook, he joined in 2015 at the company's European headquarters as Director of Small and Medium Business for EMEA. Two years later, he relocated to Silicon Valley and was handed something more interesting: Messenger Business - the unit responsible for making Messenger a place where customers and companies actually talk. Not broadcast. Not spam. Talk. He ran it from 2017 to 2019, watching businesses discover that a message window could outsell a cold call by a factor of ten.

His next stop, HeadSpin, lasted less than a year but left a mark. As SVP of Business, he was the person a senior engineer approached in March 2020 with an uncomfortable truth: the company claimed tens of thousands of mobile devices on its network. The real number was closer to 2,000 to 3,000. Loukakos left, and later submitted a declaration that contributed to the fraud prosecution of founder Manish Lachwani. He has always had a lower tolerance for spin than Silicon Valley tends to reward.
By December 2020, he was building Connectly with co-founder Yandong Liu - a Yahoo researcher and former CTO of fitness app Strava whom he met through the San Francisco founder community. The thesis was specific and, at the time, underappreciated: most retailers were bombing their customers with generic campaigns, then wondering why conversion rates collapsed. Meanwhile, in Brazil, Mexico, India, Southeast Asia - anywhere WhatsApp had saturated - customers were already shopping inside chat. They just needed the infrastructure to do it at scale.

The Company
Connectly: The Store Inside the Chat
Connectly is not a chatbot company. It's the infrastructure layer that lets a brand in Sao Paulo or Jakarta or Mumbai run an AI-powered sales rep inside WhatsApp, handling personalized product recommendations, abandoned cart recovery, payment confirmation, and post-purchase updates - without a human touching the keyboard.
The platform connects to WhatsApp, Instagram DMs, SMS, and web chat. It integrates with Shopify, Salesforce, Zendesk, SAP, and Vtex. The AI can segment customers, run campaign flows, hand off to a human agent when the conversation gets complex, and feed the data back into retargeting. Loukakos calls it a "conversational commerce" play - commerce that happens inside a conversation, not despite it.
The numbers are not subtle. Revenue grew 5x in 2023, reaching $3.5M ARR. Loukakos projected 100% growth in 2024. More than 300 brands were paying for it as of the Series B announcement. In September 2024, Alibaba - the company that turned WeChat-style commerce into a multi-hundred-billion-dollar industry in China - led a $20M round at roughly a $100M valuation. That investor choice was not random. Alibaba knows what a commerce layer inside messaging looks like when it works at scale.
Loukakos is not shy about the endgame. He sees messaging platforms evolving into Western equivalents of WeChat - a super-app where you discover, compare, purchase, and track a product without ever leaving the interface. "The elimination of cookies will only accelerate this," he has said. When you can't retarget customers across the web, you build direct relationships with them. And the most direct relationship a brand can have with a customer is a conversation that they initiated.
He is also clear-eyed about AI's role. "They shouldn't be afraid of it. If AI is installed and works well, it can really bring amazing results." Connectly's Sofia AI - launched after the Series A - handles product recommendations in real time, pulling from a brand's catalog and matching against customer behavior patterns observed across the conversation history. It is the kind of system that, to use Loukakos's framing, can do the same job as a skilled sales associate - and arguably better, at three in the morning, in six languages simultaneously.
Perspective
What a Greek Engineer Saw That Silicon Valley Missed
There's a useful lens for understanding Loukakos: he grew up professionally in markets where WhatsApp was not a novelty but the default. Working on Facebook's European and EMEA business meant working with small business owners for whom messaging was already the primary channel. When he moved to the US and took over Messenger Business globally, he brought that frame with him - one shaped by markets where "two-way messaging" was already table stakes.
The US was different. Email, web chat, phone support. The mobile-native messaging commerce that was already standard in Brazil, India, and Indonesia had not crossed the Pacific in either direction. Loukakos was watching it happen in real time at Facebook and running the mental arithmetic on what the gap would be worth once it closed.
He also holds three degrees - engineering from UC Berkeley, engineering from Stanford, an MBA from INSEAD - which might explain why his company's tech stack runs on Apache Kafka, Amazon MSK, and Google AlloyDB while his sales pitch sounds like a retail consultant's memo. He can speak both languages because he spent 25 years learning both.
