The named end of this market, and a genuinely small one. Above a certain scale a data enrichment decision has a real owner and a real budget, and below it the retailer simply uses whatever the platform ships with. Long cycles, high value, and a market small enough that anyone working in it knows the accounts by name.
Who signs: chief customer officer, director of digital or ecommerce, head of health and nutrition, data and product information director.
