What's the best way to support a product on launch day?

Hi there! We just launched Hopscotch Flow on product hunt (https://www.producthunt.com/posts/hopscotch-flow), and I'm wondering whether anyone has some helpful tips / tricks on how to support a Product Hunt launch during the day? What's worked best for you? What are some of the coolest tactics you've seen others do on launch day? P.S. Flow is a FinTech product that enables you to unlock funds tied up in outstanding invoices with just a few clicks. No credit check & completely private. Sharing as this might impact feedback!
