If this were a video to market to customers or clients, I would suggest letting him speak the whole time. Because your accent might get in the way of selling the product.

But when you're applying to an accelerator, the product you're selling is your team. You're an integral part of that team, and you need to show the YC folks what they're getting with you as part of that team.

YC seems to be trying to address the gender gap in startup founding, so I don't think that being female will put you at a disadvantage. And there are plenty of other foreign founders of successful startups.

Try to relax, speak slowly and as clearly as you can, and record as many takes as you need to feel confident that you can be understood. You'll be fine.
