If you wouldn’t mind marking which of these are startups, that would be amazing. I have been researching them online and for some of them it is hard to distinguish which ones are backed startups vs. private companies.

    @ 3:41 pm

    All the companies on this list are Private, so their exact capital structure is not public information. However, I do not believe that any of the companies on this list are profitable enough to be self-funded. All of these companies have either received funding from a venture capital firm and/or a corporate investor or they are looking to get funding from an investment source. We do list the venture investors and their portfolio companies on the Venture Capital page when and if the investments are announced.

    The one company that some might not call a startup is D-Wave since they were founded in 1999. Most of the rest were founded within the last few years.

ID Quantique acquired by SK Telecom…

    @ 10:14 am

    If you read our news article dated February 28, 2018 on the $65 million investment in ID Quantique by SK Telecom, it indicates that SK has a large ownership position in ID Quantique, but it is not 100%. There are still other entities that own portions of the company. As a result, we will continue to list ID Quantique on this Private/Startup page since it is not a 100% owned subsidiary.
