Celebrating Seoul and its Extraordinary Rise to the World's Top 10 Startup Ecosystems

Authors: JF Gauthier, Founder & CEO at Startup Genome, and Chuzen Kin, Director, East Asia, Startup Genome

A decade ago, Seoul was best known to the world for its global conglomerates – Samsung, LG, Hyundai, SK – and its export economy. Today, the city is becoming something different: a Top 10 startup ecosystem where new technology companies are built and scaled.

Seoul’s Surge in Numbers

Seoul climbed from 54th in 2018 to 8th last year in the Global Startup Ecosystem Ranking, putting it ahead of Berlin, Paris, Shanghai, and Tokyo.

Why Seoul? Talent, infrastructure, and density

Seoul's advantage is not a copy of Silicon Valley. It is something more distinctive.

Few cities concentrate as much engineering talent, advanced digital infrastructure, corporate research and development, and consumer-tech adoption inside a single metropolitan area. Korean universities produce one of the world's highest densities of STEM graduates. The city's broadband, mobile, and payments infrastructure rank among the most advanced in the world. And Seoul's dense urban environment, deep engineering bench, and active corporate ecosystem support what Startup Genome's data identifies as the city's strongest sub-sectors – Artificial Intelligence, Big Data, Life Sciences, and Advanced Manufacturing and Robotics.

A transformation built over time

Seoul's growth has been built over time. Long-term public investment, university research, corporate participation, and private venture activity have steadily deepened the ecosystem's foundations.

The Seoul Metropolitan Government has channeled public capital into the ecosystem through initiatives such as the Seoul Vision 2030 Fund. The Seoul Business Agency has supported programs focused on startup global expansion, innovation hubs, and ecosystem connectivity.

What Seoul founders are building

In Artificial Intelligence and Semiconductors, Seoul is becoming part of the global race to build next-generation AI infrastructure.

As demand for AI computing grows, specialized inference chips that can deliver strong performance at lower power and cost are becoming increasingly important. Korean engineers, with decades of semiconductor design experience inside companies such as Samsung and SK Hynix, are well-positioned to compete.

One company attracting global attention is Gangnam-based FuriosaAI, which designs AI inference chips that match competitive performance at roughly a quarter of the power consumption of Nvidia’s H100. The company declined an $800 million Meta acquisition offer in 2025 and is preparing for a 2027 IPO.

In Life Sciences and Medical AI, Seoul has built one of Asia’s most data-rich healthcare environments. A single-payer insurance system, dense hospital networks, high digital health adoption, and leading academic medical centers – including Seoul National University Hospital, Asan, Samsung, and Severance – create a strong base for clinical research and commercialization.

That environment has produced a generation of globally-relevant medical AI companies. Gangnam-based Lunit, now listed on KOSDAQ, develops AI-powered cancer diagnostics used across more than 10,000 medical institutions in 65 countries. Its breast cancer risk prediction tool earned FDA Breakthrough Device designation in 2025.

Seocho-based Vuno, also KOSDAQ-listed, builds AI solutions for medical imaging and biosignal analysis. Its DeepBrain product is FDA-cleared, and its cardiac arrest prediction tool DeepCARS became the first AI-based medical device reimbursed by Korea’s national health insurance system.

In Fintech and Financial Services, Seoul’s high smartphone penetration, mature digital payments infrastructure, and consumer appetite for integrated mobile services have created fertile ground for super apps.

The clearest example is Gangnam-based Viva Republica, operator of Toss, a financial super-app used by close to half of South Korea’s population. The company is preparing for a U.S. public listing in 2026 at a targeted valuation of more than $10 billion.

In Advanced Manufacturing and Robotics, Korea’s industrial base is creating another layer of opportunity. Automotive, shipbuilding, electronics, and logistics companies are under pressure to automate as skilled workforces shrink and global competition intensifies.

Seoul is becoming a more visible center for robotics development and testing, with research, testbed, and commercialization activity concentrated across districts such as Yangjae, Suseo, and Gangnam.

Seocho-based Seoul Robotics offers a glimpse of where this is heading. The company builds infrastructure-based autonomous driving software that turns conventional vehicles into self-driving fleets inside factories and ports – technology now deployed by BMW, Volvo, and Mercedes-Benz.

Why this matters for Seoul

For Seoul, the implications extend beyond technology alone. A stronger startup ecosystem strengthens the city's long-term economic resilience. It creates opportunities for younger generations. It supports local businesses and services. It attracts international attention and investment. And it helps build confidence that Seoul can continue reinventing itself in a rapidly-changing world.

The AI era is only beginning. The cities capable of adapting fastest and generating the industries of the future will shape the global economy for decades to come. Seoul's recent trajectory suggests it intends to be one of those cities.

“Seoul's rise as a global startup city shows what happens when leadership, vision, investment, and world-class talent come together in one place. Our work now consists of making sure this engine of growth delivers sustained prosperity to our citizens for the next decade and beyond.” — Hyunwoo Kim, CEO, Seoul Business Agency (SBA)
