Ask HN: Resource to find and learn more about interesting companies/startups

I want to find out thing that I don't know yet about big companies and promising startups. There's a lot of companies out there. But I can only find their job posting and some relevant pages about their market, products. Those pages usually for marketing purpose, which are not what I'm looking for. I want to know: - Who are they, beside the well-known names like Google, Facebook, Microsoft, Amazon, Dropbox, Grab, Uber... - How is their financing status? - Who are they competitors, and how would they fight (the differences between them and competitors, the strategy, scale, R&D) ? - Their history. FWIW, I'm seriously looking for a new job, where I would contribute my time to build something interesting. During searching, it's feel like I'm learning about building my own startup. But I don't want to. I think it better to join an already growing company, because my network is narrow, and I know nothing about financing, funding, etc.
