Expanding to Korea? Which City Should Your Startup Start From?

hero

If you're thinking about expanding your business to Korea, it is very easy to assume that Seoul is the best place to start.

And honestly, there is a reason for that. Seoul is Korea's largest business and startup hub, home to major companies, investors, universities, government institutions and a large concentration of international businesses. The city also has a growing support network specifically for foreign entrepreneurs, including the Seoul Global Center, Global Startup Center and OASIS programmes.


But choosing Seoul simply because it is Seoul can mean overlooking something important: Korea's startup ecosystem is not concentrated in one city.


Different cities have developed around different industries, institutions and business networks. Some are better connected to investors and international business. Others are particularly strong in manufacturing, logistics, deep tech, research, maritime industries or regional markets.

So if you're coming to Korea, the question isn't necessarily “Should I choose Seoul?”


It is:


“Which Korean city makes the most sense for the business I am trying to build?”

Here are five cities worth considering.


1. Seoul: Best for founders who need the widest business network

If your priority is access to investors, corporate partners, talent, international organisations, customers and Korea's largest concentration of startups, Seoul is still the obvious starting point.

The Seoul Metropolitan Government operates Startup Plus, a platform where startups can find support programmes, investors and startup support facilities across the city. Seoul also has multiple startup hubs, including Seoul Startup Hub Gongdeok, M+, Changdong and Seongsu.

For foreign founders, Seoul has another major advantage: there is already infrastructure designed around international entrepreneurs.


The Seoul Global Center provides foreign entrepreneurs with startup support and expert consultations covering areas such as law, taxation and management. Seoul also runs OASIS programmes covering startup coaching, incorporation support and incubation.


The Global Startup Center also provides support around visa, incorporation and patents, alongside startup programmes and a dedicated workspace for international entrepreneurs.


Best suited for:

SaaS, consumer tech, fintech, AI, digital services, international business, content, e-commerce and startups that need frequent access to investors, large companies and a broad customer base.

The trade-off: Seoul gives you access, but it also puts you in the middle of Korea's most competitive startup market. If your business does not need to be in Seoul, there may be advantages to looking elsewhere.

2. Incheon: A strong middle ground for international and globally oriented businesses

Incheon is particularly interesting for foreign founders because it gives you access to a major international gateway while keeping you within the wider Seoul metropolitan area.

You are close to Incheon International Airport, and areas such as Songdo have developed into important business, technology and international-development centres.

But Incheon is also building its own startup ecosystem.


One example is the Incheon Foreign Startup Competition (IFC), which connects foreign startups with opportunities in Incheon and provides selected companies with support around areas such as funding, office space and startup establishment. The city also has programmes and infrastructure aimed at attracting and supporting foreign entrepreneurs.


Incheon International Airport Corporation has also been running startup and venture support programmes. Its 2026 Win-Win Startup & Venture Enterprise Support Programme, for example, offers selected eligible companies commercialisation support and an opportunity connected to international expansion.


That makes Incheon particularly interesting for businesses connected to logistics, aviation, mobility, smart cities, international trade and technology, as well as foreign founders who want access to the Seoul metropolitan area without necessarily placing the business in central Seoul.


Best suited for:

Logistics, aviation, mobility, smart-city technology, international trade, B2B technology and businesses looking for an international gateway.

The middle-ground advantage:

If you are based in Incheon, Seoul is still highly accessible. And if you are based in Seoul, Incheon is close enough that you can make use of its airport, business ecosystem and opportunities without relocating your entire operation.

3. Busan: For businesses that want to build beyond the capital

Busan is a particularly interesting option if your business has a reason to be connected to ports, logistics, maritime industries, tourism, manufacturing or international trade.

It is Korea's largest port city and has been actively developing its startup ecosystem as part of its goal of becoming a global startup city.


In 2026, Busan announced a package of six startup support programmes aimed at companies from the prospective-founder stage through to startups with up to seven years of experience. The programmes cover around 200 companies and include commercialisation and scale-up support, with some programmes offering up to KRW 100 million in support.

Busan also has its own startup support infrastructure through the Busan Startup Portal and Busan Startup Investment Agency. Available support includes incubation spaces, acceleration, mentoring, global exchange and investment attraction programmes.


Foreign founders can also access dedicated support. Busan operates a Global Startup Immigration Center, with OASIS-5 startup coaching and mentoring for foreign students and residents interested in establishing technology startups and pursuing the Technology Startup Visa. It also offers OASIS-8 corporation establishment support for foreign prospective founders.

And Busan is not disconnected from the wider technology ecosystem. Events such as K-ICT WEEK in BUSAN bring together AI, cloud, ICT and smart-city companies, while the city's international programmes connect local startups with overseas markets.


Best suited for:

Logistics, maritime technology, mobility, tourism, manufacturing, AI/ICT, smart-city solutions and businesses that want to connect with Southeast Asian and other international markets through a major port city.


4. Daejeon: Consider this if your business is built around technology and research

Daejeon is a very different proposition.

Rather than competing with Seoul on the size of its consumer or corporate market, Daejeon's strength is its research and technology ecosystem.


The city is home to major universities and government-funded research institutes, and its startup policies place a strong emphasis on technology commercialisation and deep tech.

Daejeon's startup support system includes support for deep-tech companies through university and research-institute partnerships, accelerator programmes, business support and investment connections. The city is also expanding its startup spaces and has programmes for social ventures, technology commercialisation and companies preparing for international expansion.


For technology founders, this can be a significant advantage.


If your company depends on research, patents, advanced technology or university and laboratory partnerships, being closer to the institutions developing that technology can be more valuable than simply being in Korea's biggest city.

Daejeon also supports companies participating in overseas technology events, including a dedicated Daejeon pavilion at CES.


Best suited for:

Deep tech, AI, robotics, biotech, advanced materials, research-based startups and companies that need university or research-institute partnerships.

5. Pohang: A smaller city with a serious technology ecosystem

Pohang may not be the first city that comes to mind when you think about starting a company in Korea.

But for certain technology businesses, that is exactly why it is worth looking at.


Pohang is home to POSTECH, one of Korea's major science and technology universities, and has been developing a startup ecosystem around research, technology commercialisation and regional innovation.

In 2026, POSTECH, Gyeongsangbuk-do and Pohang City launched a programme investing KRW 300 million to select and support 10 promising software startups, covering areas from technology development and market entry to global expansion.

POSTECH also operates a dedicated startup support system covering the journey from identifying and validating an idea through to follow-on growth support.


For a founder whose company is closely connected to university research, engineering or technology development, Pohang can therefore offer something that a much larger city cannot always provide: proximity to a specialised research ecosystem.


Best suited for:

Deep tech, software, engineering, advanced technology, research commercialisation and startups that could benefit from POSTECH's research and talent ecosystem.


So, Which City Should You Choose?

There is no single “best” city for every foreign founder.

A simple way to think about it is:

If your priority is... Consider... Investors, corporations, talent and the widest networkSeoulInternational business, logistics and access to SeoulIncheonPorts, maritime industries, logistics and tourismBusanResearch, deep tech and technology commercialisationDaejeonEngineering, software and university-linked technologyPohang


And these choices are not as isolated as they might appear.


Seoul and Incheon are particularly close, making it possible to build your business in one while regularly accessing the ecosystem of the other.

Busan also sits within the wider southeastern industrial region, meaning founders working in sectors such as manufacturing, logistics and advanced technology may find opportunities beyond the city itself.


The important point is that your registered business location does not have to be a reflection of where you think Korea's “main startup scene” is.

It should reflect where your customers, partners, suppliers, research institutions, talent and support programmes are.


Before Choosing Your Korean Base

Before signing an office lease or registering your company, ask yourself:

  • Who needs to be close to me?

Customers? Investors? A university? A port? A manufacturing partner? A research institute?

  • Which ecosystem can actually help my company grow?

Look beyond the number of startups in a city. Check its incubators, accelerators, funding programmes, corporate partnerships and sector-specific support.

  • Do I need Seoul every day?

If the answer is no, another city could give you a better fit while still allowing you to travel to Seoul when necessary.

  • What happens after incorporation?

A city may have an attractive startup programme, but check whether you actually meet its eligibility requirements as a foreign founder or as a Korea-registered company.


And perhaps most importantly, do not choose your location before understanding your business model.

Seoul may be the right answer for one founder and completely the wrong answer for another.


Korea's startup ecosystem is bigger than one city. The better question is not “Where is everyone else?”


It is “Where does my business have the best chance of finding the people, infrastructure and opportunities it needs?”
