Imagine a software founder in Seoul who has built an app to help small stores plan their stock. Two shop owners are interested in trying it. Before agreeing to a paid trial, the founder needs to check three things: whether he may do the work under his current immigration permission, what the customer agreement should cover, and how to learn whether stores will pay.
Several organizations offer help to foreign founders in Korea. Their names can sound similar, and “startup support” can describe anything from a short conversation to a class, workspace or a competitive funding program. Choosing a useful service begins with the decision the founder needs to make.
This guide follows that fictional founder, Sam, as he sorts his questions and prepares his inquiries. It explains what different providers can do, what to bring and how to check whether a service is available for the business's current stage.
What kind of help would move the business forward?
Sam has a prototype, an early version of the app used to try the idea. A pilot would be a small trial with a customer. Neither word means he has already formed a company, gained work permission or proved that the business will succeed. Those are separate questions.
For his first contract question, Sam needs a consultation: a conversation with someone who can explain the issue and the next step. The conversation may reveal that a professional needs to draft or revise the agreement. That further work requires its own agreed scope and may involve a fee.
For the customer question, a mentor may help him plan interviews, review an offer or think through costs. A mentor gives guidance about the business. The stores themselves will decide whether to buy.
A startup program brings a set of services together under its own participation rules. It might offer classes, mentoring, office space or support with specified costs. Eligibility means meeting the conditions for that program. A grant provides money under stated terms; an invitation to attend a class does not imply that funding is included.
These distinctions lead to four useful questions for any provider: does the service cover these circumstances, what work will it do, what will it cost, and when can it be used? Answering them early makes it easier to choose between a consultation, a professional engagement and a program application.
Four names that are useful to recognize
The Global Startup Center, usually called GSC, supports foreign founders. Its Seoul facility is in Gangnam. It is operated by the Ministry of SMEs and Startups and KISED, the Korea Institute of Startup and Entrepreneurship Development.
Seoul Global Center is a different city support facility in Jongno. Its services include professional consultations and programs for foreign entrepreneurs. Checking the full name and address helps avoid booking with one center while expecting the services of the other.
OASIS stands for Overall Assistance for Startup Immigration System. It is a system of support activities delivered through participating centers. Depending on the activity and provider, those can include education, mentoring, help concerning intellectual property, and company-formation support. Intellectual property concerns rights in things such as inventions and brands; a patent is a legal right in an invention. OASIS itself is neither a single office nor an immigration status.
KOTRA is the Korea Trade-Investment Promotion Agency. Its Invest Korea service assists foreign businesses with investment in Korea. That makes it a useful starting point for questions about bringing investment into a Korean business and the procedures involved.
The organizations overlap in some areas, but a specific question makes the choice clearer:
- For permission to stay and do particular work, start with immigration guidance and check whether a provider's visa consultation covers the case.
- For overseas investment and the establishment process, ask Invest Korea's Investment Consulting Center.
- For a contract, tax or business-planning question, look at GSC Office Hours or Seoul Global Center's professional consultations.
- For workspace, a class or money for a project, read the notice for that exact service or program.
Checking permission before agreeing to work
Sam's first question concerns what he may personally do in Korea. His status of stay is the immigration category under which he lives here and carries out permitted activities. A service that helps form a company cannot, by that act alone, settle his permission to work in it.
The Ministry of Justice's Immigration Contact Center, 1345, provides multilingual information on immigration affairs. From within Korea, callers can dial 1345 and follow the language prompts. It is a source of guidance about the appropriate procedure and office; a guidance call does not itself grant permission.
Sam prepares a short description of his nationality, location, current status and the work he plans to do. He explains the app, the proposed owners, where funding would come from and whether a Korean company exists. The useful question is whether his present permission covers developing the app and delivering the proposed paid trial, or whether he needs an approval first.
GSC's visa-consultation page lists one-on-one consultations for founders holding D-10-2 or D-8-4 status. These concern technology-startup preparation and startup activities. A founder should confirm that their case is covered before booking. The same page states that GSC cannot extend visas or issue recommendation letters for extensions.
An OASIS activity may help someone prepare for a technology-startup route. Participation is only one part of a wider process. Our D-8 visa guide explains the routes to investigate. Sam still needs the permission question answered for his actual duties before relying on a proposed customer trial.
Getting the company and investment sequence clear
Sam has not yet formed a Korean company. Incorporation means creating a corporation with a legal identity separate from its owners. It is one part of establishing a business. The wider sequence can also involve tax registration, investment procedures and permissions connected with the activity.
If funds will come from abroad, the first inquiry should explain who is providing the money, who will own the Korean business and what it will do. An overseas company funding a Korean subsidiary, for example, has a different ownership arrangement from an individual starting a business alone. A subsidiary is a separate company owned by another company.
The Invest Korea Investment Consulting Center offers free investment-related consultations and help with foreign-investment notification and registration. Those procedures report and record qualifying investment. Its listed service languages include English, Chinese, Japanese and Korean.
A simple ownership diagram and description of the proposed money transfer can make the conversation more productive. The questions are which procedures apply, which records are needed and in what order the steps should happen. A transfer from abroad should not automatically be treated as qualifying foreign investment.
GSC also describes an incorporation service. The founder prepares documents and submits information for review; the center then works with a partner law firm where appropriate. Eligible ventures receive help with part of the attorney fees, while founders remain responsible for administrative and service fees. The founder should request the work covered and their own expected costs before proceeding.
For Sam, these inquiries can establish a sequence before he commits to a company structure or moves money. Our guide to starting a business in Korea places those steps in the wider plan.
Making a contract or tax consultation useful
A broad request such as “Please help with my startup” leaves a provider guessing. Sam can make the contract question concrete by bringing a draft and a one-page description of the trial. That page says what the store would receive, what it would pay, how long the trial would run and who would do the work.
GSC Office Hours offers free one-on-one expert consultations for foreign founders and prospective founders in South Korea. Topics include legal issues, patents, visas, tax, accounting and business planning. A prospective founder is someone preparing to start a business.
As checked on October 14, 2026, the page advertises rolling applications and displays an application window ending April 30, 2027. Rolling applications means requests are accepted through the stated period. The process begins with a questionnaire so the team can match the question with an expert. The appointment is confirmed afterward; an open application window does not guarantee an immediate session.
Seoul Global Center's 2026 expert-consultation notice advertises free in-person advice in areas including law, tax and management, with applications through December 2026. Its center information page also lists professional consultations. The center should confirm the suitable expert, available appointment and working language.
At the consultation, Sam asks what needs resolving before he agrees to the trial. For example, what happens if the app fails to do the promised work, or the store requests extra features? He marks clauses he does not understand so the expert can focus on them.
Before leaving, he asks whether further drafting or review is needed, who would do it and what it would cost. For ongoing legal or tax work, the founder should confirm the professional's Korean qualifications and the agreed service scope. A free introductory conversation can be valuable without covering all later work.
A tax consultation needs different records: the proposed payment, who would receive it, the business's registration details and the relevant agreements. The business-tax guide explains how to prepare those questions. Monthly bookkeeping and filing should be discussed as a separate continuing service.
Using mentoring to plan the next customer test
The two shop owners' interest gives Sam a reason to investigate further. He still needs to learn who decides whether to buy, what problem matters most and what the stores would expect at his proposed price.
He brings the early app, notes from both conversations, the proposed price and an estimate of the work involved. A mentor can help him choose a narrower question for the next discussion, such as whether a store would pay to reduce time spent checking stock.
GSC Office Hours includes business-model advice. A business model explains how a business serves customers and earns money. GSC's OASIS program page also describes education and startup mentoring, subject to its technology-startup participation rules and the relevant intake.
Program dates need close reading. The posted GSC OASIS page still displays a May 18, 2026 application deadline. That date has passed, even though application links remain on the page. Before planning around a place, ask which round is currently accepting applications and request its current eligibility rules and dates.
Mentoring can improve Sam's test, but the stores' decisions remain the evidence about demand. If a paid trial is lawful and agreed, payment shows commitment to that offer under those conditions. It does not yet show that the app can be delivered profitably or that many more stores will buy. Our Korean market-testing guide explains how to make the next test useful.
Checking what workspace and funding provide
A founder may need somewhere to meet a customer or work between appointments. GSC's spaces page describes coworking areas and bookable rooms, and asks first-time visitors to pre-register and check in. Confirm access rules and availability before traveling there.
Using a desk or meeting room does not necessarily include permission to use that address for business registration. If the company needs a registered address, that use should be asked about explicitly.
An incubation program helps a young business develop, often through workspace and advice. Seoul Global Center's 2026 OASIS-7 incubation notice describes a June-to-December program with applications advertised for May 6 to May 20. A program can still be running after recruitment has closed. A founder seeking a place now should ask about a new intake or separately announced vacancy.
Funding notices need the same distinction. Commercialization means turning an idea or product into something sold to customers. GSC's 2026 commercialization-support page concerns selected foreign technology startups. It is marked “Result Announced,” with applications ending April 10, 2026 and a program period continuing into 2027. The listed application period has closed.
For any new funding opportunity, read the current notice before including it in a budget. Check who may apply, what spending is covered, what the business must pay itself and when funds become available. Applying, being selected and receiving usable money are separate stages. Essential costs need a plan that does not depend on an unconfirmed award.
One clear inquiry and an agreed next step
Sam could send this fictional inquiry about the contract consultation:
“I am in Seoul and preparing a software business. I have an early working app and two stores interested in a small trial. A Korean company has not yet been formed. I am checking permission for the work separately with immigration. I would like advice on the draft customer agreement, particularly the promised work, payment and responsibility if something goes wrong. Can your service help at this stage? I can provide the draft and a one-page trial description. Please confirm any fees and the next available appointment in English.”
A useful inquiry explains the founder's location, business stage, decision and available documents. Immigration details belong in it when relevant, along with the preferred language. Specific questions help a provider confirm fit or direct the founder elsewhere.
After each conversation, Sam records the answer, the work still needed, who will do it and the next date or action. For this business, progress means knowing how to resolve work permission, arrange a suitable customer agreement and learn how stores decide to buy. The next useful contact is the one equipped to answer the next unresolved question.
Sources and scope
Official provider pages and notices checked October 14, 2026. Advertised services and program periods do not establish a current appointment, open recruitment or individual eligibility. Confirm circumstances, fees, language and availability with the provider. This is a general guide to finding help; individual immigration, legal, tax and funding decisions require the appropriate authority or qualified professional.
