Research briefRead more
Long Journey Ventures Research Investment Thesis Long Journey Ventures is an early-stage venture capital firm that believes in backing "magically weird" founders building unconventional solutions. Founded by Lee Jacobs and Cyan Banister, the firm explicitly positions itself as a "second believer"—the early supporter who sees potential before it's obvious. Their tagline, "The second believers in the magically weird," captures their core philosophy: they seek founders working on ideas that others describe as ridiculous or stupid, combined with bold personalities who challenge the status quo. The firm's investment approach is rooted in long-termism and founder support. They describe their relationship model as "being a bubbe"—a Yiddish term for grandmother—emphasizing hospitality, wisdom, protectiveness, directness, and unconditional support paired with uncompromising integrity. They view their character alignment as "Chaotic Good" (a Dungeons & Dragons reference), combining good hearts with free spirits, valuing freedom and individual autonomy above all else. Stage and Check Size Focus Long Journey Ventures is definitively an early-stage investor, focusing on pre-seed and seed-stage companies. Their portfolio companies span from concept stage through Series A/B. Based on visible portfolio activity, they write checks in the range of $500K-$2M+ for seed investments, with smaller checks for pre-seed.

The firm maintains a "bubbe" operational philosophy, prioritizing authentic relationships, community events (hosted as intimate dinner-like gatherings), direct communication, and hands-on support. Geographic Focus Primary focus on US-based founders (San Francisco, Silicon Valley bias evident), but portfolio includes some international companies. Co-founder Lee is based in San Francisco. Recent Activity & Fund Status The firm appears to be in active deployment mode with consistent investments across 2024-2025. Portfolio diversity and advisor network suggest strong deployment velocity. No indication of fund-raising or between-fund status. Notable Philosophy The firm's values reveal deep philosophical commitments: "Chase the magically weird": Unconventional ideas, quirky personalities "Be a bubbe": Hospitality, wisdom, protectiveness with integrity "Chaotic Good character alignment": Balance freedom with doing good "It's not Monopoly money": Serious stewardship of LP capital, not reckless These principles suggest they're not mercenary venture capitalists but impact-oriented investors with personality and principles.
