Bitcoin Forum

 I would like to find something like coinmarketcap but for companies. Is there anything like that out there?

As far as I know there isn't a big site like coinmarketcap but there are a few lists of companies that use bitcoin, some of them are very big companies, check this out:

https://www.lifewire.com/big-sites-that-accept-bitcoin-payments-3485965

You can also buy content with bitcoin at Microsoft on xbox or windows store. This might be the biggest company that accepts bitcoins right now but there might be others.

 I don't mean companies that accept bitcoin.

 I mean companies that are related to bitcoin.

 Like blockchain.info , kraken, coinbase, bitpay, poloniex, primedice   and so on.

 Companies that are ONLY bitcoin related. Not just bitcoin accepting companies.

I would have thought Bitmain would be the biggest

If miners do count i honestly think these guys make a ton load of bitcoins per day

and because their rigs are constantly running especially those with alot of harsh power

i would have suggested a gambling site but with the current high priced bitcoin

am certain these are not rainy days for casinos and sportsbooks imo i think exchange sites have the potential to fill this spot.

It's hard to answer your question. Many of bitcoin related services are not officially registered companies and it's hard to determine their value. But probably, most popular companies/services is the highest valued - Coinbase, Blockchain.info, Localbitcoins, maybe even bitcointalk.org

Two things here.
1. Coinmarketcap gets automatically data very easy from sources to present you accurate information without any work.
2. Many of bitcoin related services are not officially registered companies and it's hard to determine their value and its impossible to determine automatically. Physical person would need to TRY to find out this data, which is often not public accessible.

So its impossible in short.

maybe add big exchanges like poloniex.com and bittrex.com in the top list, primedice for being number 1 in gambling.

tho, this forum is valued $ 56,750,000 when i searched a little in google: http://www.worthofweb.com/website-value/bitcointalk.org/

And exactly why you are looking for this information? Simple curiosity or you would like to invest in some of those companies or some other reason?

Gemini.com is a registered company ,based in NY and owned by Winklevoss twins. you can check it .

what are the current values of bitmain and kraken.com ?  How much are each companies worth?  1 Billion each?

You not going to find this info. This is exactly the sort of info market researches want and is worth a lot of money. Noone is going to hand over something if great value. Billions are spent each year when companies try find out what s competitor is up to and what they worth or what market co trol they have. These are exactly the things the strategies about in their board meetings. So no you won't find answers.

I don't really understand about the thread title and the thread content.

But, if you looking for bitcoin company list, wiki have it, here are go: https://en.m.wikipedia.org/wiki/List_of_bitcoin_companies
Although it's not complete, you need to searching more and sorting out the credibility, because company/business related to cryptocurrency is vulnerable to be a scammer.
