A month ago we got our first subscription, he was disappointed. Today we made $32 in our pre-launch campaign

Hello. We are Datasketch and we are building a Data Visualization SaaS.

The first day we set up Stripe we got our first subscription for $20 USD/month. The product wasn't ready yet and I realized it would still take at least two more months to make it usable enough.

One month after this first sale, I figured we couldn't wait to have the product completely ready, so we set up this landing page and sent a mass email to our contacts.

We started offering $1USD yearly subscriptions. We made $32 in the first 24 hours and got 62 users to signup. I think this may give the users some ownership of our product so that they can help us improve it in the next few weeks and maybe help us in the actual launch. Any similar experiences?

If you think you will need to make a chart or a map during the next year, would you help me and buy a yearly plan for $1USD?

Thanks, what do you think?
