Pokémon cards have apparently outperformed the S&P 500 since 2004 🤯 (~3,800% return according to WSJ). Honestly, I just wish I had kept all my cards from 20 years ago ... Crazy how culture turns into value. These aren’t just pieces of cardboard. They’re memories, communities,

Soft capital is fragile. Too often, it ends up scattered across spreadsheets, inboxes, and memory. That fragmentation comes at a cost: continuity, trust, relationships. The right tools can keep it whole.
