Interview (Apr 15, 2024) with Elizabeth Caley (co-founder & co-CEO of Poppy) about building a company that measures and digitizes airflow in buildings. Origins: after a prior exit and time at SRI, founders pursued bringing lab-grade biomedical measurement approaches into buildings to detect airborne pathogens and, more broadly, to measure airflow. Pandemic acceleration: COVID forced rapid deployment, producing unique installed-system data that led Poppy to pivot from detection toward digital measurement of air flows and a commercial focus on building owners (HVAC optimization, energy savings, compliance). Tech & IP: Poppy built hardware, iterated with advisors in aerosol/built-environment science, patented solutions and contributed to an industry testing approach referenced during ASHRAE241 standard development. Leadership themes: deep co-founder trust (long-standing relationship with Sam), an explicit co-CEO model with clear division of superpowers (Sam: technical/product scouting; Elizabeth: scaling/go-to-market & experience), and deliberate communication rituals to avoid confusion. Other topics: remote/hybrid work practices, hiring leaders from large companies and researchers, and candid career advice (be blunt, seek diverse viewpoints).
