The North Sydney Innovation Network (NSIN) is a not-for-profit innovation and technology group dedicated to promoting and enhancing innovation-related businesses, particularly startups and fast-growth businesses, within the North Sydney region. With the aim of fostering collaboration and boosting the contribution of these businesses to the local economy and community, NSIN focuses on three key intentions: NETWORK, EDUCATE, and ADVOCATE. Through networking events and connections, NSIN creates opportunities for stakeholders in the northern Sydney innovation ecosystem to share ideas and increase knowledge.

They organize regular free events, including Meetup networking sessions and collaborations with other organizations. Education is another focal point, as NSIN provides thought leadership, support, and guidance to local governments, entrepreneurs, and startups. They emphasize the promotion of STE(A)M subjects among students at all levels of education and keep their members updated on the latest innovation and technology initiatives.

In addition, NSIN advocates for a collaborative network of innovation-driven entities in northern Sydney. They strive to connect and support all three levels of government in backing local startups and technology-driven businesses through formal and informal advocacy, including government submissions. By fulfilling these purposes, NSIN contributes to the growth, prosperity, and economic development of the northern Sydney innovation ecosystem
