O POSITIV is a Los Angeles-based health & wellness brand built on the idea that small acts of self-care produce positive outcomes. We’ve created the first-ever PMS gummy vitamin, FLO Vitamins, to make periods and the symptoms that come with them more tolerable. FLO is formulated from time-tested herbs and vitamins, natural flavors, and not much else. We’ve got no time for that “time of the month” and even less time for sketchy ingredients. Because we believe personal health should be effortless and intentional. Our team is small-yet-mighty, with big ambitions and an entrepreneurial spirit. We are an early-stage startup gaining serious traction (check us out in Forbes’ top trends in women’s health), with a strong brand presence and some amazing advisors. We’re growing quickly, and we’ll give you the opportunity to do the same.

We're making the protein shaker extinct, and we're looking for people who want to build the category, not just fill a role. The problem: whey requires measuring, shaking, and a bottle that smells by day two, and it physically hurts the majority of Indians who are lactose intolerant. We asked 50+ manufacturers to fix it. All 50+ said impossible. We built it anyway, our latest batch hit 22g protein in just 40ml, closing in on our 24g target, nearly double the density of India's closest RTD competitor, through proprietary formulation nobody else has cracked. This is genuinely early. Which means real ownership, real equity, and the kind of influence over product, brand, and go-to-market that disappears the moment a company gets big. You won't be executing someone else's roadmap, you'll be writing the first draft of an entire category. We want people strong exactly where the mission needs them most: manufacturing and ops execution, or growth and brand-building for a format that doesn't exist yet anywhere in India.
