Joseph Jacks positions himself as a COSS missionary who coined and popularized the Commercial Open Source Software category, arguing these companies are structurally different from SaaS and deserve their own metrics and playbooks rather than generic approaches. He runs OSS Capital as a hyper-focused, category-only firm that exclusively invests in COSS startups where the company would not exist without an open source core, and has built the LP base as a curated open source brain trust of iconic founders from companies like WordPress, Red Hat, MongoDB, and GitHub.
What they've been talking about across their social media accounts

- A strong conviction in commercial open source software as a superior model for high-growth startups. He frequently validates this thesis by pointing to the rapid expansion of companies within his own firm's portfolio, citing specific examples like Hoppscotch to illustrate how focusing on open developer tools leads to success.
- Comparisons between biological intelligence and modern computing, often arguing that the human brain is vastly more efficient than current artificial intelligence hardware. He breaks down the math of processing power per watt to show that organic structures, such as cellular microtubules, still outperform the largest silicon superclusters by a significant margin.
- Interest in foundational hardware physics and moving beyond traditional computing architectures. He critiques current tech giants for having financial incentives to ignore fundamental inefficiencies in how computers process data, suggesting that true innovation requires rethinking the physical substrate of computing rather than just making chips faster.
- Deep engagement with Eastern philosophy and metaphysics as a framework for understanding consciousness and intelligence. He regularly references ancient Sanskrit texts and the Upanishads, drawing parallels between these spiritual concepts and the scientific pursuit of understanding the mind and the universe.
- Commitment to decentralized networks and incentive structures that challenge centralized ownership. He demonstrates this through his long-term support of protocols like Bittensor, explaining how he holds these assets through volatility because he believes in systems that separate the symbolic representation of understanding from traditional ownership models.
