Retail is enjoying a fintech Renaissance of sorts -- from BNPL and other new forms of payments to a maturation of the ecommerce checkout experience. Fast is building one-click checkout on merchant sites across the internet. Much like Uber made payments invisible, Fast is doing something similar for shopper identities. Creating accounts on sellers’ sites has always been an impediment to the payment flow. Fast takes away that friction with an elegant solution that shares user information with merchants and also integrates to include SKU-level data. Allison Barr Allen is co-founder and COO of Fast. She joined Fast from Uber, where she was head of global product operations for the Money Team. As my guest on the podcast, Allison describes some of the challenges inherent in ecommerce payments. We chat about the opportunity to go both global in scale as well as niche down into specific industry solutions. Allison Barr Allen is my guest today on the Tearsheet Podcast.
