Mark and Quinten bring to LightInTheBox tremendous global leadership and extensive domain expertise, which will be critical for the Company’s long-term growth. Further, the establishment of a U.S. office for LightInTheBox through this transaction brings us closer to our customers, and provides us the opportunity to acquire an extremely talented team. We are excited to welcome Ador’s talented employees to LightInTheBox and are pleased to use this acquisition as a means to bolster talent and further maximize our global e-commerce sales opportunity.”
