Gathered 50 emails from interested developers

I basically put up a landing page presenting the product, and created Facebook ads to redirect people to the landing page. Within a week I had the 50 emails.

I plugged Airtable to the form on the landing page so I could save the emails there and added Slack notifications to keep me motivated 😌

After reaching 50 emails I stopped so it doesn't empty my bank account... But all in all, it costed about $50.
