Ask HN: Privacy Shield for non-US company who stores data in US

Solo founder here working on our GDPR compliance efforts. We are a Canadian company, but since 80% of our customers are in the US, I made a decision early on to have all of our databases in the US.

Our infrastructure is not trivial, so replicating it to the EU is not economically feasible at the moment.

I was looking into how to get certified under EU-US Privacy Shield, but since we don't have a US address, we cannot even start the process.

Anyone else in a similar situation? Any guidance will be appreciated.
