This is a Quora question. My answer is as follows.
https://www.f6s.com/programs looks like it has a comprehensive list of accelerator programs that startups can apply to. Some funds are CPG focused and you can go to their websites to see individual prospects.
As mentioned by Bukola Ekundayo, CircleUp is CPG focused, but for somewhat larger prospects that may be past angel round and in their series A round.
There are probably many local networking groups in cities. An example is http://NaturallyBoulder.com, which is natural product focused in Boulder. CO, with members from the local CPG startup scene. It is harder to find groups like this because they are not listed in any directory that I know of.
