The Korean government offers various grants that foreigners can apply for.
One of the grants is the GSC Commercialization Program, which provides up to $45K and is designed for non-Koreans scaling in Korea.
Another grant is the K-Startup Grand Challenge (KSGC), which offers funding, mentoring, and Korea entry to global talent.
There are also Startup Packages, such as the Pre, Initial, and Leap Packages, which provide $30K-$90K, equity-free, but require a visa and Korean language skills.
