Worked at a company almost 2 years, exercised my stock options (only $2k, it was my 2nd junior position and I didn't negotiate for equity at all). 4 years later

Worked at a company almost 2 years, exercised my stock options (only $2k, it was my 2nd junior position and I didn't negotiate for equity at all). 4 years later I have no idea how much they're worth, if they even still exist, or if there's been any liquidity event. If I had to guess based on the company's revenue, they're probably worth about 4x what they were when I exercised, but I'm planning on holding off on trying to do anything with them unless I see the company in the news for a big liquidity event in the future.
