Philip Sebastian is a 🏷️#founder, product operator, and 🏷️#designer building AI-native products at the intersection of trust, clarity, and real-world utility. He is currently building Korpus, a trust infrastructure tool for verifying suspicious messages, screenshots, and links, and Moonrise, a wellness and longevity platform with a calmer AI posture. He also operates Sidequest Ventures, a curated builder community for designer-led founders and accelerator alumni.

Previously a product designer at 📝Apple and founding designer on 📝SAP Build — part of SAP's global developer platform ecosystem — Sebastian brings a practitioner's eye to product development across AI, fintech, developer tools, and consumer wellness. He founded RecurPal, a 📝B2B subscription management platform backed by 📝Y Combinator alumni, and Bankroll, a financial literacy concept for teens and families. He has advised and contributed to products at Golden, Paragon, and Amplemarket, and holds accelerator alumni status from On Deck, Antler, Pioneer, Y Combinator Startup School, and Buildspace. He has also served as 📝Entrepreneur in Residence at Manhattan Venture Partners. His operating principles — clarity over complexity, trust as a product layer, and AI as noise-reducer rather than amplifier — run through all his work.
