In 2022, we launched IMPACT SOLUTION, an online platform to match GreenTech companies with B2B clients; followed by the launch of our IMPACT TALK podcast with guest experts and the second festival, which welcomed 2,500 attendees. Furthermore, we co-hosted the IMPACT WEEK, the IMPACT AWARD, and various smaller side events such as webinars and online lectures.
