Ask HN: Can you get a J1 visa for your startup if admitted to an accelerator?

Hello, immigration is a perennial question here on HN. Does anyone have any experience of sponsoring themselves as a J1 visa? Is this possible? We have been admitted to a relatively prestigious accelerator in the bay area which I think should qualify for the training requirement for the visa. My co-founder is American and with advisors and others my share is below 50%.
