Sometimes you quickly need to find out who the big global, regional or country players are in an industry. Here's a free search option that will provide that - The Global 5000. The first 50 matches from a search cost nothing, but then you have to pay, and yes, that's a bit pricey. The data can then be 'sliced 'n' diced' on both public and private companies worldwide by industry, employees, and revenue, where available. Depending on what you are looking for, I think the free search option can save a lot of legwork.
