Home to 60 per cent of the world’s population, Asia is the locus for significant global challenges such as the future of work, gender inequality, inequitable access to health care, and climate change. For these entrenched socio-economic challenges, the time is ripe for philanthropist and philanthropic capital to taking a leading role in addressing and resolving these issues. Connecting like-minded individuals and building bridges to collaboration is one of the core functions of ecosystem builders like the Asian Venture Philanthropy Network (AVPN). Since its founding in 2011, AVPN has grown into Asia’s largest social investment network, with over 600 members active across 33 markets. It has incubated several successful partnerships, but the journey has not always been smooth sailing. As the network has grown and evolved, so has its value proposition and role in the community. This chapter shares some of the lessons AVPN has learned in its journey to become an inclusive, responsive, and resilient ecosystem builder for philanthropy in Asia. It calls on philanthropists to build more intentional partnerships with ecosystem builders to facilitate more long-term, sustained change on the ground. The chapter points out that sector intermediaries should seek out opportunities to support philanthropists in building the community – the best way to resolve systemic development issues – rather than work alone.
