Ms Tan Peck Ying (Science ’11) is the co-founder and CEO of Blood<\/a>, a Singapore-based menstrual health company on a mission to normalise periods and make them more manageable. She met her co-founder and husband Mr Caleb Leow (Business ’15) while enrolled in an entrepreneurship module at the National University of Singapore. Both went on to participate in the NUS Overseas Colleges (NOC)<\/a> programme, where Ms Tan witnessed firsthand how curiosity could be the starting point for building something real. The itch to start a business was hard to ignore.<\/p>

Today, Blood’s products are stocked at over 7,000 retail locations across Singapore, Malaysia and Indonesia including Guardian, Watsons, NTUC FairPrice, Cold Storage, and 7-Eleven. Its bestselling corn-based sanitary pad, the first of its kind in the world, absorbs liquid three times faster than cotton, and is naturally hypoallergenic.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Launched in 2014 as PSLove, the company’s first product was MenstruHeat<\/a>, a drug-free adhesive heat patch born from Ms Tan’s own struggle with debilitating period pain. Rather than seek outside capital early on, the couple chose to maintain sustainable unit economics and reinvest profits back into the business, a carefully considered approach that allowed them to stay in control of their own trajectory.<\/p>

The defining move came in 2022: a full rebrand to Blood, and the launch of the world’s first corn-based sanitary pad, designed absorbs liquid three times faster than cotton and naturally hypoallergenic.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\u201cRebranding our brand was bold, but it would have been risker to continue playing it safe. We saw what we often call \u201ca sea of sameness\u201d; brands portraying women skipping through white lily fields, smiling on their period.

“Periods are not blue liquid, they\u2019re not always graceful. They can be messy, inconvenient and uncomfortable, and that\u2019s completely normal. We wanted to build a brand that challenged those norms, to be openly contrarian yet real.\u201d<\/p>

Friends, investors and retailers were shocked. Some loved it, some didn’t. But as Ms Tan intended, nobody could forget it. “From our brand name to packaging, it sparked conversations. Maybe that’s how speaking about feminine health should have been all along.”<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

FINDING THE PATH TO ENTREPRENEURSHIP WITH NUS OVERSEAS COLLEGES<\/strong><\/p>

Ms Tan’s pivot to entrepreneurship was less a lightning bolt moment and more a gradual reckoning. When studying Biomedical Science at NUS, she somehow felt restless. “I didn’t enjoy the routine of lab work, the repetition and the inability to make things happen the way I wanted to.”<\/p>

In her final year, she dropped her final year project (FYP) and pursued a business minor instead, a decision that surprised her family and friends, and turned out to be the best one she made in university.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Participating in the iLead\/NOC Singapore programme and working at NUS Enterprise<\/a> was where she got immersed in the start-up space.<\/p>

“I have been connected to many good mentors through the ecosystem. For example, Brian Koh connected us to someone from P&G. Since they are in the consumer space, they know what works in the market, how the distributors work, how to manage exports, and marketing and pricing strategies.”<\/p>

Scaling Blood also meant growing as a leader and a mother, and that has come with real trade-offs. “The most significant sacrifice in the last few years has been time with my kids. When I first became a parent, I honestly didn’t anticipate how challenging it would be. At the same time, the company was growing. My kids were growing. Both needed me in completely different ways. There were definitely seasons where it felt like a constant tug of war.”<\/p>

However, an investor’s words stayed with her. “You have agency to build your life the way you want. Building the team in such a way that you can grow the business and still feel like engaged, involved parents; that should be the goal.”<\/p>

She never liked the idea of having to choose between building a company and being present for her children. That discomfort pushed her to redesign how she led the business.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\u201cI needed to build a company that was not dependent on me reacting to every fire or being involved in the day-to-day operations.

“I DON’T THINK OF MYSELF AS A FEMALE ENTREPRENEUR.”\u00a0<\/strong><\/p>

Ms Tan is measured and clear-eyed on the subject of gender. \u201cTo me, an entrepreneur is an entrepreneur.\u201d When asked what are her thought on the old idiom that behind every successful man stands a woman, she doesn\u2019t hesitate. \u201cIf I were to rewrite that idiom, it wouldn\u2019t be about who stands in front or behind. It would be: ownership and resilience aren\u2019t gendered. Neither is success.\u201d<\/p>

By choosing to bleed happy and loud, periods today no longer just end sentences. They spark conversations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
