Building for Impact: John Salzinger on Haven, Energy Access, and Mission Control

In this episode of Journey to Regeneration, Christopher Marquis speaks with John Salzinger, entrepreneur and inventor behind portable solar lighting company Haven, about building a commercially viable solar business around the challenge of energy poverty. Salzinger explains a distinctive model in which the same product sold to mainstream retail customers is made available to NGOs at lower margins rather than replaced with a cheaper impact-market version. He discusses Haven's decision to work with NGOs and nonprofits before entering retail, using demanding humanitarian settings as both a route to impact and a proving ground for product durability. The conversation also examines one of the central tensions in social enterprise: how financing and ownership can determine whether an impact mission survives as a company grows or changes hands. Salzinger reflects on lessons from the sale of his prior solar start-up MPOWERD and explains why Haven has remained self-funded alongside a small-business loan, allowing its owners to retain control over pricing, product quality, and mission. Also explored are the unavoidable trade-offs of physical products—from manufacturing impacts and battery materials to durability, e-waste, and affordability—and why pursuing a long useful life can matter more than claiming perfection.
