Sebastian Gabor
Sebastian Gabor is the co-founder and CEO of Digitail, an AI-native, cloud-based practice management platform for veterinary clinics. A serial entrepreneur from Romania, he previously built the development studio ITGambit to nearly 100 engineers and co-founded the civic-tech non-profit Code4Romania. He started Digitail in 2018 with Ruxandra Pui after a vet handed him his dog's vaccination schedule on an illegible sticky note - a moment that led him to discover most animal hospitals still ran on software from the 1990s. Today Digitail serves more than 10,000 veterinarians and millions of pets, and in November 2025 raised a $23M Series B led by Five Elms Capital.
Ana-Maria Constantin
Ana-Maria Constantin is the CEO and co-founder of Cascade AI, a Bellevue-based startup building agentic AI that automates the grind of HR and back-office operations. A Harvard dual major in computer science and astrophysics who left Romania after high school, she spent five-plus years as a software engineer at Microsoft writing code that touched millions of users on Azure before deciding HR - the function that touches more lives than any other in a company - was the perfect place to point machine learning. She raised a $5.45M-plus seed round led by Google's Gradient Ventures with AlleyCorp, was named GeekWire's Young Entrepreneur of the Year in 2024, and recognized as a 2025 Google Cloud Partner All-Star.
Andrei Stefan
Andrei Stefan is the co-founder and CEO of Oveit, an Austin-based event technology company that bundles smart ticketing, online bookings, access control and cashless payments into one platform. A Romanian operator with two decades in general management and finance, he moved from corporate boardrooms into startups, helped build a live-shopping and streaming platform during the pandemic, and pushed Oveit early into NFT and blockchain-based tickets through partnerships with Crypto.com and Polygon. Oveit was named by the UN World Tourism Organization in 2019 as one of the five most disruptive startups in tourism.
Raul Popa
Raul Popa is the co-founder and CEO of TypingDNA, a behavioral biometrics company that recognizes people by the rhythm of how they type. A self-taught coder turned sociology-and-statistics graduate, he turned keystroke dynamics into a commercial authentication API used in banking, finance, and online education. He started the company alone in 2016 in Romania, brought it through Techstars and a Google-AI-backed Series A, and relocated it to New York just before the pandemic. Beyond enterprise security, he shipped TypingDNA Focus, a free app that predicts your mood from your typing.
Bogdan Apostol
Bogdan Apostol is the co-founder and CEO of Nestor, a San Francisco-based AI-powered people intelligence platform that helps enterprises build skills-based organizations. A Romanian-born computer scientist with a PhD in Computer Vision from Gheorghe Asachi Technical University, he founded Nestor in 2018 after being accepted into Y Combinator's S18 batch. Before writing a single line of product code, he conducted over 400 customer discovery calls. Nestor has raised $6.07M in funding, serves 10,000+ employees worldwide across F500 companies, and has earned 67 G2 badges including a perfect 10/10 for quality of support.
