For us it was through a Kickstarter (https://medium.com/@alexobenauer/how-i-launched-my-company-w...), and the majority of the first 100 backers (that I didn't already know) were from Hacker News.
But through working with our customers for years, we saw that while we really helped people get their email more organized, we weren't solving the root problem: that anyone can dump anything they want into your inbox in the first place.
We felt called to double down on a killer solution we figured out for that problem first (https://throttlehq.com/).
your buttons also need some left and right padding. my company would love to help put your best face forward..
