Exploring start-up ecosystem in 'luru

Hi folks! Am new to the city, working for an MNC and recently got the role of Project coordinator (but similar to PM) but along with this, I want start exploring the startup ecosystem here in Bengaluru. Am still figuring out my niche. Could you guys please suggest what kind of events I should attend to meet people, what are some of the X (Twitter), Reddit, Instagram or any other such SM pages to follow so that I am relevant with the things happening here? I am up for part time jobs and apprenticeships if available to start immediately or after skilling up myself with the requirements.

PS. As I am still finding my niche, any sector is good enough to begin with, but since I am a Biomedical Engineering Graduate, I would prefer something in the Medtech arena.
