Client lead and AI educator
Karen Sartin
A British educator who has spent more than three decades making unfamiliar, personal, and complex subjects easier to act on.
Karen is the first person every Gadg.ai client meets. She leads needs discovery, communication, training, and human review, helping technical and nontechnical people turn a rough request into a clear, useful outcome.

“I’ve worked with several people who understand AI technology, but far fewer who understand both AI and how people actually learn. Karen brings those two disciplines together extremely well.”
A career built in rooms with people
Teaching came before the technology.
Karen’s authority starts with knowing how people learn, where confidence breaks down, and how to turn expert knowledge into repeatable practice. That same skill now guides every client conversation.
She began her professional education at Northampton College in England, then built her early career in London. At The Red Door by Elizabeth Arden, she combined senior client work with hiring, training, service quality, and sales coaching while maintaining approximately 90% client retention.
In Bermuda, Karen became Education Manager at Bersalon. She trained and coached employees across five spa locations, built a five-day onboarding curriculum, created presentations and operating protocols, served as Guinot's trainer for Bermuda, and remained a top producer.
In the United States, she later led 12 group fitness classes a week for an average of more than 30 participants, with groups as large as 45. Those rooms taught her to explain clearly, adapt in real time, maintain standards, and keep every experience level engaged.
