Overview
InnoSpark Inc. was a South Korean mobile-game development company established in April 2012 by members of the team behind Rule the Sky, a mobile title published by JCE. The company focused on free-to-play social and strategy games designed for smartphones and other connected platforms. Its first major release was Dragon Friends, a social farming and collection game built around breeding and collecting stylized dragons. The game was initially serviced through NHN and launched in August 2013. It received recognition as a notable new release on the Korean Apple App Store in December 2013. InnoSpark later took over direct service of Dragon Friends in South Korea and 175 additional countries beginning on February 27, 2015, reflecting the company’s effort to operate its products across a broad international audience rather than relying entirely on external publishing partners. InnoSpark expanded into strategy gaming with Hero Sky: Epic Guild Wars, released in Korea with Nexon in August 2014 and launched internationally in 154 countries in March 2015. The game combined base-building and guild-war mechanics associated with the mobile strategy genre with a more elaborate hero system. It reportedly reached three million downloads in 2015. The Korean service was reopened in July 2015, indicating an effort to revise or relaunch the domestic operation after its initial release. The company attracted outside investment as it developed its international and China-market ambitions. It received a reported 2 billion Korean won investment in March 2013 and raised a $6.5 million Series B round in June 2015. The Series B financing was led by Keynote Ventures, with participation from SL Investment and Company K Partners. InnoSpark said the capital would support continued game development and expansion into China. The company continued to pursue publishing opportunities in 2016, signing a publishing contract for Trendy Town on October 20 of that year. Its corporate life ended after it was acquired and absorbed into PUBG Labs. InnoSpark closed in November 2017, leaving its principal legacy in the early international mobile-game market and in the development of titles that combined accessible social mechanics with persistent online progression.
History
InnoSpark was founded on April 19, 2012, in South Korea by members of the team responsible for Rule the Sky. Its formation placed the company within the early wave of Korean studios building games specifically for smartphones and online distribution. Rather than concentrating on a single domestic product, InnoSpark developed games intended to support long-running service operations and international rollout. The company’s debut title was Dragon Friends, a social farming game focused on breeding and collecting cute dragons. NHN initially participated in its service, and the game launched in August 2013. Dragon Friends received recognition as a best new entry on the Korean Apple App Store in December of that year. InnoSpark also secured a reported 2 billion Korean won investment in March 2013 and formed a partnership with NHN in June, providing early commercial support for its development and publishing activities. InnoSpark’s second major title was Hero Sky: Epic Guild Wars. The strategy game launched in South Korea with Nexon on August 8, 2014. It used familiar base-building and competitive guild-war concepts but added a more complex hero system. The title expanded beyond Korea with a global launch in 154 countries on March 19, 2015. Its Korean service later reopened on July 8, while the game reportedly reached three million downloads during 2015. International service became a more explicit part of InnoSpark’s business model in 2015. On February 27, the company began directly servicing Dragon Friends in Korea and 175 other countries. This shift gave InnoSpark greater control over distribution and live operations across a large group of markets. The company also pursued additional financing and growth opportunities. In June 2015 it completed a $6.5 million Series B funding round led by Keynote Ventures, with SL Investment and Company K Partners participating. The stated uses of the funds included continued game development and expansion into the Chinese market. The studio remained active in 2016, including through a publishing agreement for Trendy Town signed on October 20. However, the available record does not document a long subsequent period of independent operation. InnoSpark was acquired and absorbed into PUBG Labs, after which the company closed in November 2017. Its history therefore spans a relatively short period, but it illustrates the rapid development, internationalization, financing, and consolidation of the Korean mobile-game sector during the 2010s.
