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.

Congrats on your sales 👏
Thank you
Sorry, but this isn’t very clear to me. What type of data are you giving them?
That's why I should put up a landing page. It's a scraped list of twitter handles from IH, with their public twitter informations like bio, followers count, account creation date.
Lol, I need my coffee I wonder why I didn't take a screenshot at first place.

This data is from September 15, there is the same data from August 15 for those who wants to compare.
Very cool! Great work :D
Why do you think this would be useful to people here? I'd love to hear your part of the story.
Thanks Brayden, it's also a great question and it's kind a long to answer.
Initially I build the list for myself because I knew I needed some social exposure for my future projects. With this list basically I can easily find like-minded people to connect with. If I need to expand it further, I can filter it with follower counts, feed my listener bot with the users. Or simply create a list on twitter and join in the conversations when I'm able. It's more likely to work for a beginner on twitter. Except trying hard to get noticed under big guns.
I have this design related idea in my mind for a while, I can search for designers easily with their metrics and engage with them, gather feedbacks or see if their products fits my idea.
I'm also analyzing the growth to see if I can apply the tactics from the bests.
It's nothing but a scraped list but allows me to do many things. If I can't do anything, it helps me to keep alive the Data group on IH. :)
Very smart! This answers my question. Thanks again!
