How This Female Founder Grew a $5K Startup Into a $3M Period Care Business With Amazon | Entrepreneurship | Katie Diasti | Presented by Amazon

Episode of Young and Profiting (YAP) with Hala Taha: Entrepreneurship and Self-Improvement Podcast · October 27, 2026 · 52 min

Hala Taha interviews Viv founder Katie Diasti about bootstrapping a sustainable period care brand from a college project to multimillion-dollar revenue using Amazon.

Summary

Recorded at Amazon Accelerate 2026 as part of a sponsored How We Profit miniseries, this episode featured Katie Diasti, founder and CEO of Viv, a period care brand selling bamboo-based pads, organic cotton tampons, menstrual cups and discs. Diasti described how the company began as a Boston College entrepreneurship class project informed by her volunteering at a women's shelter, and how she reneged on a corporate job offer after pre-selling hundreds of pads at Boston farmers' markets. She also discussed her Egyptian-American family's initial discomfort with the subject and their eventual support.

Diasti explained that Viv started in 2019 with $5,000 from an accelerator, negotiated a $3,500 first production run despite manufacturers' high minimum order quantities, and hand-packed orders in her apartment. She said Viv launched on Amazon first because of speed of delivery and fulfillment capacity, and described using A+ content, social media videos, Seller Assistant analytics, keyword analysis, Subscribe & Save promotions and affiliate links to drive sales and shape new products such as cup and disc starter kits.

She recounted a 2024 viral response to studies on heavy metals in tampons that exhausted six months of tampon inventory in three weeks and created a waitlist of over 3,000 people. Diasti said Viv expected $3–4 million in revenue for the year, had grown roughly threefold annually, and maintained margins above 70%. She described raising an initial $500,000 from mentors she had kept updated, then a $2 million seed round once profitable, and argued that a strong Amazon business is effectively a prerequisite for successful entry into retail, where Viv is now in about 2,000 doors.

  • Hala Taha

    Taha argues that founders who raise investment before having sales tend to overspend and negotiate less.

  • Katie Diasti

    Diasti says she pre-sold hundreds of pads at farmers' markets before the product existed.

  • Katie Diasti

    Diasti says Amazon suited period care because customers need products quickly and often don't plan ahead.

  • Katie Diasti

    Diasti recounts that after Viv responded to 2024 heavy-metal studies, it sold six months of tampon inventory in three weeks.

  • Katie Diasti

    Diasti argues that high margins are essential because brands can lower prices later but cannot raise them.

    “And it's almost like a death wish to not have high enough margins because it's something where like, we know we can, as we scale”

    Listen from 44:38 · Profit margin

  • Katie Diasti

    Diasti believes raising millions before launch would have led her to spend much of it poorly.

    Taha cites the marketing principle that Amazon lets sellers channel existing demand rather than create it.
