Hi! I'm currently chasing convexity through systems managing over $1B in value across MRGN Group. Here is a bit of my background, some media, some writing, and answers to questions you might have:

📍
Location (2022) NYC

Work

Presently, I'm iterating in a nascent industry with a shrewd team at the intersection of finance & permissionless systems. Previously, I built a hedge fund, sold a healthtech company, & grew orgs at-scale before dropping out to invest & work in Web3.

Contact

I get a lot of messages, so here I'll set expectations for those reaching out. If you are contacting me for one of the following reasons, please take a look at my response before doing so.

Investing

I prefer founders who are building complementary solutions to things I have enabled. I can't promise feedback, but please do email me your deck or idea!

Speaking

I will consider the opportunity if it aligns with my interests. It's usually better if I have a personal relationship with the organizer or if it's a smaller audience of <50 attendees.

Students

I prioritize conversations with those who have dropped out. Unless a degree is critical to what you do, I may not have the bandwidth to chat if you are currently enrolled.

Advising

I am focused on building mission-critical systems right now, but if you still feel like I could be uniquely positioned to help, please do reach out.

News

Sometimes people write about the stuff I work on. Here are a few of those pieces I have saved:

Press

Dating

Do not be afraid to reach out. I am attracted to driven, smart, creative women. I am currently 24 years old, 6ft 1in and decently athletic. I deeply love my dog Bō, Coldplay, Damien Chazelle, Christopher Nolan, Pink Floyd, Denis Villeneuve, Nils Frahm, Max Cooper, Ólafur Arnalds, and — most of all — learning new things.
