I start things when I see something missing, and I build them. As a teenager I started a homework group on Facebook and turned it into a tutoring business, and later I co-founded a falafel bar. Today I run sales and marketing at Aryze, a payment infrastructure company in Copenhagen.

COSI, under DARA
Committee Member, Strategic Advisory Board, January 2026 to now
COSI, the Consortium of Stablecoin Issuers, brings together companies that issue and exchange stablecoins, digital money tied to a normal currency. They work together on education, market integrity and safeguards against fraud. COSI is part of DARA, the Digital Asset Regulatory Authority, an industry-led self-regulatory group in the US. In January 2026 I joined COSI's Strategic Advisory Board with two colleagues from Aryze. I bring what we learn about reconciliation, currency exchange controls and audits from building payment and stablecoin products. In October 2026 the advisory board met in person for the first time.
