Lawrence Leuschner is a committed impact entrepreneur dedicated to fighting climate change through sustainable businesses. He started his professional journey as an early entrepreneur, selling his father's discarded items, and later founded rebuy.com, a circular economy platform that extended the life of over 100 million products. After dedicating 15 years to rebuy.com, Leuschner took a break to travel around the world, where he had an up-close view of natural devastation caused by climate change, further inspiring his passion for sustainability. He went on to found TIER Mobility, now Europe's leading mobility platform for safe and sustainable transportation on shared, electric modes, such as bikes, mopeds, and scooters. He expanded his mission by founding Blue Impact Ventures in 2018, a fund that backs green tech impact space businesses, focusing on sectors like clean mobility, regenerative farming, solar housing, and food waste reduction. Leuschner has pledged his entire stake in TIER to the climate mission through Blue Impact, and all profits are reinvested in the fund.
