Jason Mackey combines venture capital investing with active political engagement, having run for Massachusetts state representative and served as CEO of the Economic Rights Council, while positioning himself as part of the Council for Inclusive Capitalism to integrate economic policy themes into his investing approach. Unlike most venture investors who focus primarily on software, he built his perspective through founding companies across diverse sectors including energy services, supply-chain operations, and executive networks, giving him hands-on experience in both digital and traditional asset-heavy industries.
What they've been talking about across their social media accounts

- Focuses heavily on the rapid evolution and societal impact of artificial intelligence. Views advanced models as fundamental platform shifts rather than simple conversational tools, and frequently reflects on the balance between commercializing these technologies and managing their safety risks. When pitching AI startups, it is important to know that building a business solely around crafting inputs for language models might not land well, since this specific skillset is viewed as a passing trend rather than a real long term job function.
- Advocates strongly for increasing urban housing supply and tackling the real estate crisis. Shows deep support for creative zoning and building initiatives, pointing out specific examples like converting vacant commercial office buildings in Lower Manhattan into residential apartments to meet market demand. Founders working on property technology, urban development, or construction efficiency will find a highly receptive audience who believes building more residential infrastructure is essential.
- Analyzes major market shifts and user experience flaws across big tech platforms. Readily critiques mainstream consumer products, predicting the eventual downfall of traditional search engine models and pointing out that new social networks fail when they rely too heavily on strict moderation and algorithmic feeds rather than organic user interaction. Pitching software to this audience requires demonstrating a robust, user friendly design that avoids the bloat and top down control seen in current legacy platforms.
