## Company Overview

Gainful is a personalized sports nutrition company founded in 2017 and headquartered in New York City. The company's direct-to-consumer model begins with a detailed intake quiz that captures each customer's height, weight, fitness goals, activity level, and dietary preferences. Based on quiz responses, Gainful formulates a custom protein powder blend—choosing from whey, plant-based, or collagen protein bases—tailored to the individual's specific macronutrient needs and taste profile. Flavoring packets are sold separately, allowing customers to control sweetness and taste variety without reformulation.

Gainful has expanded its personalized nutrition platform beyond protein powder to include hydration products, pre-workout formulas, and supplement stacks. Each product is formulated to the customer's profile and shipped on a subscription cadence. The company offers access to registered dietitians who can answer nutrition questions and help members refine their supplement regimens—adding a human guidance layer on top of the algorithmic personalization engine.

The company raised $11 million in total funding, including a $7.5 million Series A co-led by BrandProject and Courtside Ventures in January 2021, with participation from AF Ventures and Round13 Capital. Gainful has processed more than 2 million quizzes and doubled revenue between 2019 and 2020. The brand expanded into retail through a Target-exclusive product line, bringing personalized nutrition to a broader audience beyond its core DTC subscriber base. Gainful competes with Huel, Ritual, and Athletic Greens in the premium nutrition subscription space.
