The brief
Katie Diasti founded Viv after developing a sustainable period-care concept at Boston College, choosing the uncertain path of entrepreneurship over a corporate job.
With only a few thousand dollars, Diasti negotiated around large manufacturing minimums, hand-packed early orders, and used preorders to validate demand before products arrived.
Amazon FBA became an operating advantage: outsourcing fulfillment gave Viv’s small team more time for education, content, community, and brand building.
Viv used Amazon search and SKU-level profitability data to improve products, build accessories and bundles, and focus advertising on categories such as cups and discs.
The clearest stress test came in 2024, when viral attention sold six months of tampon inventory in three weeks and created a waitlist exceeding 3,000 people.
Diasti’s broader lesson is practical rather than glamorous: sustainable growth depends on knowing margins, communicating through shortages, and converting attention into repeat purchases.
