About

Justin Carlson is the founder of Invivus Technologies, a healthtech startup on a mission to solve the indoor mold epidemic. After becoming severely ill from hidden mold exposure, Justin spent three years recovering--an experience that shaped his vision to build real solutions for others facing environmental illness. He created MoldGuide AI, a platform that helps travelers and renters find healthier stays using community data and environmental risk factors, and is also developing a real-time mold sensor to bring visibility to one of the most overlooked health hazards we face today.

Moldmap - Find places that make you feel great

Most travel and housing platforms only show you photos and location. Moldmap helps you understand whether a place will actually support your health. Discover better hotels, vacation rentals, and housing using human reviews, owner verification, and environmental data. Filter by carpet-free, fragrance-free, HEPA & more. Whether you’re highly sensitive to mold, chemicals, or fragrances--or you simply want a healthier place to stay or live--Moldmap helps you make more confident decisions.
