Jimmy Clare

Jimmy Clare

Jimmy Clare is an autistic keynote speaker, podcaster, and founder of CrazyFitnessGuy®, a wellness platform that makes neurodiversity, mental health, and sustainable habits practical for everyday life. Growing up autistic with a non‑verbal learning disorder, Jimmy was bullied in school, faced multiple surgeries and health challenges, and was often told what he would never be able to do. Instead of letting those experiences define him, he learned to turn adversity into fuel and now helps audiences do the same.

Through his keynotes and the CrazyFitnessGuy® Show, Jimmy blends lived experience, humor, and clear frameworks to help people build realistic habits, rethink what “healthy” can look like, and support neurodivergent colleagues, students, and family members more effectively. His sessions translate big ideas about inclusion, resilience, and wellness into small, concrete actions that busy people can actually use.

Jimmy likes to joke that he is “the poor Matt Damon of the speaking world”—no Hollywood budget, no stunt doubles, just a real guy who shows up, tells the truth, and helps people laugh while they rethink what they are capable of. Event organizers value his no‑fluff style, professionalism, and flexibility. He collaborates on goals and audience needs, adapts to different room setups and formats, and delivers engaging content that works for both students and professionals. Jimmy is a strong fit for events focused on autism and neurodiversity, mental health and wellness, bullying and resilience, and inclusive workplace culture.

Julia Grosse

Julia Grosse

Dr. Julia Grosse is the founder of The Cyclical CEO™, where she helps high-performing women and business teams achieve sustainable growth by syncing strategy with biology. With a background in biology and years of field research—including leadership experience during the largest polar science mission of our time, the MOSAiC Arctic Expedition—Julia bridges performance science, female leadership, and business systems.

Her career began as a scientist, but burnout and firsthand leadership experience in extreme environments revealed a missing piece: productivity and decision-making don’t operate on a 24-hour schedule, especially for women. This insight led her to pioneer rhythm-based business frameworks that combine hormonal intelligence, cognitive science, and modern productivity models.

Through her signature programs—like the Business Rhythm Blueprint and the S.C.A.L.E. Method—Julia has equipped leaders, entrepreneurs, and HR professionals across Europe to harness their natural cycles for better focus, communication, and wellbeing. Her work has been featured in New Me Event Series, Leaders Perception Magazine, and the Womanship “Behind the Bio” podcast.

Julia’s practical, evidence-based approach activates audiences: her sessions don’t just inform—they inspire action and lasting results. Whether you’re scaling a business, building resilient teams, or seeking new models for sustainable performance, Julia brings a fresh science-backed perspective that redefines leadership for the future of work.
