Founder pages are rebuilt with every index update. A founder's stats change when we add new products to the index.
Yes. If the same person is listed as a maker on products from different companies, all of those products appear on their founder page. That's one of the advantages of tracking by person rather than by company.
We track the makers listed on each product's launch page. A founder appears here if they're credited on 3 or more products in our index.
