It seems to me that PFSD is in substantially better shape than WNBD. but thanks for the heads-up on Winning Brands who look like they have progressed incredibly fast (I saw that they were trading at $0.000001 a few months ago).
I definitely like their focus on "concentrated" approaches to cleaners as it combines safe ingredients with a broader sustainability concept that incorporates (1) minimizing the use of plastics, and (2) not transporting water unnecessarily.
I think that a lot of companies are rushing into this "concentrate" space and the category is getting interest from the younger demographic. As an example, one of my own kids, who saw them initially on Shark Tank, swears by the Blueland concentrate products.
