CB Insights narrowed down the private venture and equity-backed companies in the technology landscape to a list of 531 companies, "the cream of the technology crop," as CEO Anand Sanwal puts it.
The 531 companies are likely to go on to become the S&P 500 companies of tomorrow, although they don't necessarily have to IPO in the next year to be included.
Both Sequoia Capital and Andreessen Horowitz lead the pack for the most investments in the 2016 tech "IPO pipeline" followed by Kleiner Perkins, Accel, and New Enterprise Associates.
Surprisingly, the rest of the list is now a large mix between the traditional venture capital firms and new entrants like the corporate backed funds. Google Ventures, Intel Capital, and Salesforce Ventures made the top 20. Late-stage investors like Goldman Sachs and Fidelity Investments also have big stakes in companies that are inching close to going public.
