Sigil Wen / SMA’s O-1 Visa Ambassador

Open-sourcing the skilled immigration process through extraordinary.club.

After opting out of the Management & Technology program at the University of Pennsylvania, Sigil Wen moved to Silicon Valley on an O-1 Visa to pursue his entrepreneurial ambitions. He is passionate about building innovative products and actively angel invests ($25k–$100k) in exceptional technology founders through Spearhead, under the mentorship of Naval Ravikant. Sigil is on a quest for Great Work, continually learning how to work hard and focus.

Past Endeavors

• Airchat: Co-launched with Naval Ravikant, Sigil built the viral invite loop and AI products, and recruited most of the engineering team. Airchat was successfully acquired.
• Serendipity PRM: Achieved over $2,000 in MRR within 14 days. His work led to an invitation to Stripe, where he interviewed with Patrick and John Collison. Although advised by Naval that Serendipity wasn’t venture-scalable, this experience amplified his reputation in the tech community.
• Monument: Attempted to enable crowdfunding of personal ambitions through crypto. Upon realizing regulatory challenges, he pivoted to Serendipity. Monument was backed by Naval Ravikant, Elad Gil, Justin Kan, Founders Inc., and other notable supporters.
• Bitswap: While in high school, built a bridge from a decentralized social blockchain to Ethereum, facilitating millions in volume. Featured in The New Yorker, New York Magazine, Business Insider, and more. Received a public offer of $100k for 1% of Bitswap from Dharmesh Shah before shutting it down due to the blockchain’s decline.
