Joy Liu

Joy Liu is the co-founder and CEO of Plenful, a San Francisco-based AI workflow automation platform modernizing healthcare operations. A Northwestern-trained economist who cut her teeth at Goldman Sachs and Barclays before moving into specialty pharmacy operations at Shields Health Solutions, Liu built Plenful from first-hand frustration with manual pharmacy workflows. Since emerging from stealth in 2023, she has grown the company to 60+ healthcare customers, achieved 4x year-over-year growth, and raised $76 million in total funding - including a $50 million Series B in 2025 co-led by Danaher co-founder Mitchell Rales. Named to Inc.'s 2026 Female Founders 500 list, Liu is on a mission to return time and focus to healthcare workers drowning in administrative burden.
