The company, which describes itself as a "curated online marketplace", has also recruited Sarah Atkins as head of brand marketing and Ben Irons as head of digital.
Webley-Smith starts today and will have responsibility for the marketing function as well as a place on the executive team, reporting to CEO Simon Belsham.
Belsham praised her "experiential experience and expertise", saying it would help the company build on its first ever physical retail event, Open Door, which it held last month to celebrate its tenth birthday.
Atkins, who was previously brand marketing manager at John Lewis, joined last month. Irons, who was previously head of biddable media at media agency PHD, joins today (6 June).
The hirings follow the appointment of Mother as Notonthehighstreet.com's new ad agency in April. Mother takes over from WCRS, which resigned the account last November citing creative differences, after a pitch process.
