Can you quantify the revenue impact? Do you know your userbase at all?

You’re missing some useful data that would make this decision easier.

We havent yet released the product, so we dont really have metrics around usage from international users.

We could launch English only for now, making sure that the application is ready to be internationalized in the future.

That's what i'd do. launch, get feedback.

Most people understand business-english. If your team is English-speaking, chances are, you will have much much higher chance of succeeding there.
