TheoryEx Performance is a science-driven consulting firm that helps sport, health, and performance technology companies build credibility, sharpen strategy, and grow through rigorous research and clear scientific communication.

We specialize in bridging the gap between academic research and real-world application. Our work supports companies that need defensible evidence, accurate interpretation, and compelling translation of health and performance science. Services include research design and execution, data analysis and interpretation, scientific and technical writing, and strategic advisory support across product development, validation, and marketing.

Our approach is practical and evidence-based. We design studies that align with business goals and regulatory standards, analyze complex datasets with scientific rigor, and turn results into clear, trustworthy narratives that support decision-making and product claims. We focus on clarity, quality, and impact, not hype.

TheoryEx Performance is led by Dr. Susie Reiner, a research scientist and consultant with expertise in exercise science, human performance, and health behavior. Her background spans academia, applied research, consulting, and science communication, allowing TheoryEx to operate fluently across research, industry, and commercialization.

We work with startups, established companies, and innovation teams looking to strengthen their scientific foundation, improve internal alignment, and communicate evidence with confidence.

Based in New York, NY. Supporting clients globally.
