Background

About Kaustav Sen

I’m a Senior Product Leader with 10+ years of experience building platforms at the intersection of healthtech, AI, and commerce. Most recently, I led the 0→1→scale journey for xLongevity, an AI-powered global wellness ecosystem spanning diagnostics, coaching, interventions, and e-commerce. We launched across multiple geographies—built HIPAA-compliant infra, integrated GPT & Whisper-based AI, scaled omnichannel commerce, and created a partner-driven care delivery model for global wellness centers. Earlier in my career, I helped build and scale regulated pharma SaaS platforms for clients like Biogen, Roche, Novartis, and Janssen—working on forecasting tools, KOL engagement platforms, HCP portals, and data-rich patient engagement workflows. I’ve worked across enterprise, startup, and hybrid environments—owning product strategy, design collaboration, cross-functional execution, and GTM enablement. What I bring: • Turning early-stage ambiguity into scalable platform infra • Leading AI/ML adoption in real-world, regulated environments • Building global systems across B2B, B2C, and B2B2C • Operating with founder-level ownership and execution discipline I believe great product leadership is equal parts vision, execution, and systems thinking. Let’s connect if you're building something bold.
