Meghan Markle recently mingled with an impressive lineup of celebrities and industry leaders during a star-studded business summit in the Hamptons. The Duchess of Sussex, who is known for her philanthropic endeavors and entrepreneurial spirit, attended the G9 Ventures Summer Summit, a prestigious one-day event organized by influential power broker Amy Griffin.

On Friday, July 26, Meghan’s longtime friend and makeup mogul Bobbi Brown shared a captivating carousel post on Instagram detailing her experience at the summit.

The summit featured engaging speeches from successful business owners and prominent brands, including Spanx, Bumble, Flow, Hello Sunshine, and Supergoop, as seen in Instagram Stories shared by attendees.

Meghan Markle’s presence at the business summit comes as she prepares to launch her own lifestyle brand, American Riviera Orchard. According to an exclusive source who spoke to PEOPLE, the brand aims to reflect Meghan’s personal passions and interests, including family, cooking, entertaining, and home décor. The brand name is inspired by Santa Barbara, the picturesque California town where Meghan resides with her husband, Prince Harry, and their two children, Prince Archie and Princess Lilibet.

During the summit, Meghan, 42, was spotted posing for a photo alongside Bobbi Brown, 67, and designer Misha Nonoo.
