Co-Founder & Managing Partner

Lee is an entrepreneur turned investor, dedicated to inspiring magic in the world by helping others build what they’re uniquely meant to create. At his core, Lee is a second believer—the kind of early supporter who sees potential before it’s obvious. He’s been proud to stand behind companies like Crusoe, Together AI, and Loom in their earliest chapters.

Before launching Long Journey, Lee was one of the first outside investors to complete a syndicate on AngelList, where he later became a Partner. His early conviction in the platform—and in the founders behind it—reflected a broader pattern in his career: deep belief in people and ideas that challenge the status quo.

Lee lives in San Francisco with his wife and two daughters. When he’s not investing, he’s likely building spaces—literal and figurative—where creativity, connection, and possibility can flourish.

Prior to joining Long Journey, Cyan was a Partner at Founders Fund. Her investment portfolio spans everything from rocket ships to sandwich delivery, with a particular knack for identifying companies that create jobs, empower individuals, and offer new forms of flexibility in how we live and work.

Before joining Long Journey, Arielle was at Coatue, where she helped design and launch the firm’s first early-stage fund.

Before joining Long Journey, Luke co-founded and sold a company, and helped scale another to several million in ARR and a Series B led by General Catalyst. He first fell in love with technology while working on the initial Starlink launches in 2021, where he built SpaceX’s internal launch simulation tool—an experience that shaped both his technical chops and his fascination with ambitious engineering.

Head of Operations

Dani has always loved puzzles—whether it was jigsaw challenges at the kitchen table or optimizing the family pantry. She was the kid who genuinely enjoyed sorting the Monopoly money. That instinct to create order from chaos led her into a career as a tax attorney focused on venture funds, where she discovered a deep joy in bringing structure to wild, ambitious ideas.

At Long Journey, Dani leads finance, legal, investor relations, compliance, and operations. She thrives behind the scenes, making sure the machine runs smoothly so the rest of the team can focus on finding and backing magical founders. To her, great systems are like great adventures: structured just enough to leave space for surprise, serendipity, and a little magic.

Outside of work, Dani enjoys wine tasting in Healdsburg, skiing in Tahoe, and fly fishing in Colorado.
