Leonard Rinser
Leonard Rinser is building a prevention-first longevity venture that pairs personalized diagnostics with science-based interventions—launching gevitē as its first brand and expanding toward a holistic, evidence-backed model of sustainable health. His path runs from founding GLAICE in metabolic health to catalyzing spin-outs via the Venture Institute, bridging research, technology, and entrepreneurship with partners like Fraunhofer and Max Planck. The goal is simple and demanding: make long-term health both rigorous and aesthetically compelling—so people adopt it before disease appears.
We need to shift from treating diseases after they appear to preserving health before it breaks.
Rinser argues that sustainable health starts with diagnostics-first personalization—understanding biology, environment, and behavior before prescribing action—and that adoption hinges on trustworthy data use and interoperability, not apps alone. He is candid about system frictions: design-freeze constraints that slow software iteration, reimbursement misalignments (e.g., DiGA’s pricing and incentive gaps), and a culture that treats privacy as fear, not as governed purpose. The counter-move is structural: patient data rights with real consent, harmonized standards (FHIR et al.), and business models defined from day one so value is created and captured. For leaders and founders, his playbook blends empathy with execution—map stakeholder incentives early, build with clinicians, and, when raising capital, show a path that solves a pharma/medtech pain point so exits are credible, not aspirational.
Lessons from Prevention-First Longevity:
Design for Root Cause, Not Aftercare
What we cover
-
How an API-first, white-label approach turned symptom checking into a scalable Medical Guidance Platform
-
Why evidence-anchored messaging and transparency are cultural non-negotiables in digital health marketing
-
What it will take for AI primary-care agents to be trusted—clinical oversight, regulation, and real-world outcomes
-
Where fundraising actually differs by stage—and when to look beyond Europe for speed and risk tolerance
-
Which capabilities leaders should build now—employee training in AI, strong soft skills, and feedback-rich, purpose-driven teams
Leonard Rinser is a healthcare entrepreneur with a mission to advance sustainable and prevention-focused health. He previously built a company in the field of metabolic health and is currently developing a new venture in the longevity space, centered around personalized diagnostics and science-based prevention. Alongside this, he supports leading research institutes, clinics, and venture capital firms in the health sector through the Venture Institute with a systematic approach to drive successful innovation in DeepTech and healthcare and mentors start-ups in international accelerator programs.
