What a day, I got a response from my first customer in the meantime, second sale happened. I sold a bundle which includes both August and September data.
And it was such a relief to not get a negative first response. So everything is good. Except my script, it was quite finicky when I ran it last time. Now I'm gonna need to improve it, hopefully make it faster and error-proof. (takes about 12 hours to fetch it all.) I put several other entrepreneur sites to my radar so it won't be limited with IndieHackers' users anymore.
Anyways money is stacking, soon I'll be able to open a Stripe(Atlas) account. Thus I can turn this into some kind of web application with subscription model instead of selling separately or bundled. My plan is to give a huge discount for those who support me in this very early stages.
I keep repeating myself but keep your seats early, you won't regret in the future.
note: Andrew called it a scraped list so it's officially a scrape list now on.
