### Portfolio Founders of Existing Investors
Most venture investors have invested in a large portfolio of companies. These companies have raised capital from a broad array of investors. On the Metal platform, the following is one of the most common workflows used by founders to land introductions with new investors:

You can request introductions to those portfolio founders of your existing investors that have previously raised from your target investors. This becomes a "highly probable" path given that your existing investors have a working relationship with the above portfolio founders.
