Do I need a Delaware C-corp to sell in the US?

No. A sole prop or LLC works for early revenue. Move to a Delaware C-corp when you raise US venture or want to hire US employees on stock options.

Stripe or Paddle for US launch?

Stripe if you want maximum control and can handle sales tax (via Stripe Tax). Paddle if you want a Merchant of Record that handles tax + fraud for you at a slightly higher fee.

Best launch channels in the US?

Product Hunt for the initial spike, X/Twitter for compounding audience, and one niche subreddit tied to your ICP. Skip generic PR early.
