How makers stay productive

First 100 is also an annual fee.

My Next Team, is kind of the same way, I had big plans for feature upgrades but never got around to it, so I never really marketed it. I think if you can drive traffic you can get some growth and revenue. (currently no revenue).

You can see some stats here for First 100: https://www.indiehackers.com/product/first-100-influencers It's a bit misleading because I haven't done anything to market it recently so traffic/revenue is down. But if someone has the chops at driving traffic, you would be able to make a killing.
