Trish Costello is an early architect of venture funds designed around women as lead investors and customer-experts, particularly targeting overlooked problem spaces like menopause and pelvic health that traditional investors avoid due to discomfort with intimate categories. She pioneered a structured learn-by-investing model where first-time angel investors actively participate in due diligence and deal teams as an educational on-ramp, while building a multi-decade pipeline of women decision-makers in capital allocation.
