Shopscribe (YC S21 + EF LD16) enables the 1.3M local shops in Europe – like bakeries and nail salons – to offer subscriptions for their products and unlock guaranteed recurring revenue. In 2020, an estimated 800 billion dollars was generated by small independent retailers in Europe. Very little of this is being captured in subscription models. That's because local shops don't have the technology to create subscriptions – but they really want to. Subscriptions allow shops to unlock guaranteed monthly revenue, up-sell their customers, better forecast their future sales and boost customer relationships. Subscribers get rewarded for their loyalty with special perks - such as access to workshops, gifts and discounts – together with special deals just for them!
