Lives in Berlin.

2010
A year of voluntary service in a township: rolling out IT in schools and teaching evening computer classes.
He lived with a local family. It was the first time he saw, day by day, what it costs people when no system reaches them.


2025
A fellowship year on financial inclusion: the contracts were built, the World team met, three stores in Metro Manila found.
September 2025: one pilot week on World Chain mainnet, three stores. The pilot ran as planned. A regulatory action against the identity provider in the Philippines (not against NanoCredit) paused the market.
2026
Legal structure for Argentina worked out with local counsel: a credit line to the store, a licensed peso off-ramp partner, pilot volume under the local registration threshold.
Advisory board complete, US regulatory research for a trial with a nonprofit partner, this site rebuilt. Next: ten stores near World Orb locations in Greater Buenos Aires.

Why World ID
Most projects look for a use case after the fact. Here the use case came first: credit of a few dollars, without an expensive identity check. The system does not need to know who you are, only that you are unique.
The problem
The informal standard in the Philippines. You get $5 of products today and pay $6 next week. Annualised that is more than 800 percent.
The mechanism
Everyone starts with the benefit of the doubt, and can lose it exactly one time. The smart contract stops calculating interest after twelve months, so a second chance stays possible.

NanoCredit provides store credit from $2.50 to people without a credit file. The credit settles with the merchant; the customer takes the goods home and repays when they can, at about 50 % a year. World ID proves each borrower is unique, at no cost to them. Deployed on World Chain mainnet, piloted in Metro Manila in September 2025. Next market: Buenos Aires, in preparation.
