what tool/website/group do you use to expand your network and help bring more clients in the room?

I'm in the B2B sales for about 6 months and I still struggling to hit my KPI. To be a bit more specific, I work at Gear Inc - a BPO company in Vietnam that has the main focus on customer ticket and chat support, image & text processing for dating sites and social media platforms. We have worked with Udemy, Imgur, and one of the world's biggest short-form mobile video. Would love to hear and learn more from other executives in the industry.
