TruBrain is a Venture Capital-backed functional food and beverage brand that delivers improved mental endurance and verbal fluency, validated by biomarker data. We use QEEG neurotechnology to measure the brainwaves of Athletes, CEOs, Artists, and Lawyers under high-pressure conditions to understand the brainwave patterns behind their best days and also their worst days. We gauge how various factors (stress, diet, distraction) affect performance. We believe that neurotechnology can have a big say in improving how we live. As a digitally-native, vertical brand, we do it all: from formulation and manufacturing, to marketing and web development, to fulfillment and shipping, TruBrain delivers the world’s first nootropic food and beverage products with a relentless emphasis on quality and service. TruBrain is backed by a syndicate led by Sherpa Ventures, Blueberry Ventures, Brightstone VC, and 500 Startups.
