Responsibly Ventures

Responsibly Ventures Research Investment Thesis Responsibly Ventures is a PreSeed VC Impact Fund based in Huntington Beach, California, founded in 2021 by Zécca J. Lehn. The firm backs remarkable teams building startups at the intersection of Sustainability and Social Good, using the UN Sustainable Development Goals (SDGs) as guideposts for investment selection. Their thesis is that positive impact and venture-scale returns are not mutually exclusive — in fact, their "impact moat" framework argues that mission alignment creates a unique strategic advantage that reduces risk and builds durable competitive positioning. The fund operates on a 14-year time horizon (longer than the typical 10-year VC fund), reflecting a patient capital approach aligned with the longer development cycles of impact-driven businesses. Sector Focus Responsibly Ventures targets two broad categories: Sustainable Tech: Companies addressing environmental challenges, including: Climate tech and clean energy (EV infrastructure, solar energy investment, battery technology, corporate decarbonization) Circular economy and waste reduction (surplus food, reusable packaging, e-waste recycling) PropTech for climate risk (disaster-resilient insurance data) Social Good Tech: Companies addressing societal challenges, including: Digital health and patient engagement automation Edtech and AI-powered personalized learning Privacy and cybersecurity (zero-knowledge encryption, deepfake defense) Sustainable consumer goods and marketplaces Community-focused social platforms The firm explicitly avoids vice categories and unethical business models. Portfolio companies are required to address multiple UN SDGs, with the fund having backed companies covering SDGs 3 (health), 4 (education), 7 (clean energy), 9 (innovation), 11 (sustainable cities), 12 (responsible consumption), and 13 (climate action). Stage Focus Responsibly Ventures invests exclusively at Pre-Seed . This is core to their identity — they seek to be the first institutional capital into impact-driven startups, providing the optionality needed to reach venture-scale exits while managing impact-related risks. Check Size Typical check size ranges from $25K to $250K , with a sweet spot of approximately $100K . This reflects the nature of pre-seed investing and the fund's targeted $10M fund size (raised under 506c designation). Lead Tendency As a small pre-seed fund with checks typically under $250K, Responsibly Ventures primarily participates in rounds rather than leading. They serve as an impact-aligned first-check investor that helps founders establish credibility with subsequent capital sources.
