The Action Community for Entrepreneurship (ACE) was launched in May 2003 as a national effort to facilitate Singapore becoming a creative and entrepreneurial nation where innovation and enterprise can be translated into profits and where a diversity of ideas can thrive. The organization believes that entrepreneurship is a key pillar in strengthening Singapore's economic competitiveness and complements its engines of growth in manufacturing and service industries. ACE is a movement that involves both the private and public sectors to create a more entrepreneurial environment in Singapore. It is currently led by Lee Yi Shyan, who is the minister in-charge of entrepreneurship and minister of state for trade and industry.
