Alternativeto is great. _Siftery_Product_Substitutes_ is an attempt to analyze the migration of one product to another, across companies to begin with, and later across several other segments and industries. Where we don't have any switch data, we are only showing vanilla alternatives (sorted by NPS).

This is merely v1 and we intend to iterate quickly on this dataset and provide more intelligence/decision support for buyers when they are looking for alternatives to switch to for a specific product or across a category.
