Short answer

A buying committee is the group of stakeholders, often six to ten or more people, who influence or approve a B2B purchase. Members may include end users, technical evaluators, finance, procurement and executive sponsors. Because each has different priorities, B2B marketing and sales must address multiple roles to move a deal forward.
