Annabelle Yu Long founded and built BAI Capital from scratch inside Bertelsmann in 2008, making her an early bridge figure between a major European media conglomerate and China's venture ecosystem, and combines an unusual background of electrical engineering training, TV hosting experience, and Stanford MBA education. She operates as a cross-border macro strategist for founders, personally orchestrating detailed international expansion trips like a nine-day Mexico visit for Chinese entrepreneurs that included meetings with cabinet officials and industrial leaders, while using Mexico as a deliberate model training ground for her structured playbook of helping Chinese companies expand abroad.
