Reshma Khilnani is the Co-Founder and CEO of Medplum, an open-source, FHIR-native healthcare developer platform that gives builders the infrastructure to create custom EHRs, patient portals, and clinical apps without starting from scratch. A three-time founder with exits to Box and Ro, she previously built MedXT (YC W13) and Droplet Health before returning to Y Combinator as a Visiting Group Partner and then launching Medplum in the S22 batch. An MIT computer science graduate with deep expertise in healthcare regulation and payments infrastructure, she is one of the most technically fluent CEOs in digital health.
David Winer is the Co-Founder and CTO of Ciro (YC S22), an AI-powered go-to-market platform that automates sales prospecting from target identification to booked meetings. With roots in applied mathematics, a Berkeley EECS master's, and a Stanford MBA, he spent time at Bain, Pure Storage, and Google (where he served as PM for the Kotlin programming language and sat on the Kotlin Foundation board) before co-founding Ciro in 2022 with Brown University friends Richard Lee and Ross Geiger. Ciro raised $3.8M in seed funding from CRV, Y Combinator, and SV Angel, and runs on a stack anchored by Anthropic Claude, OpenAI, and Elasticsearch. Outside the office, David self-identifies as an 'exceedingly obscure internet personality' and writes a personal blog mixing statistical deep-dives with essays on bike theft and vegetarianism.
