Gained 300 followers on twitter overnight, how do I capitalize?

Earlier this week I decided to use Twitter to validate an idea. I engaged quite a bit during the first day, resulting in a handful of people following me. I was surprised and grateful, so I made a post thanking the 8 people who followed me that day. Shockingly, a post of me being grateful for reaching 11 followers blew up which led to me waking up the following day and seeing about 100 new followers. I genuinely am grateful for the growth because not only was everyone so supportive of me, but they validated my idea at the same time. Now the hard part is the actual indie hacking and delivery of this idea to what I consider a large audience. How would you go about this if you were in my shoes?
