<h1>Global startup collaboration urged to establish international mentor-investor network to strengthen startups and enable shared innovation.</h1> A call for an international network of mentors, investors and entrepreneurs to strengthen a global startup ecosystem stresses collective responsibility to incubate and sustain startups that address global challenges. The network should facilitate idea exchange, funding and R&D collaboration through the Startup20 Engagement Group, leverage India's platforms toward a GlobalStack, expand participation from regional markets, promote digital public goods for inclusive growth, support innovation from school level via the Atal Innovation Mission, and advance bilateral and multilateral partnerships to back deep tech and social-impact startups under the guiding SENSE approach.
