Have been building Saleswhale (https://www.saleswhale.com/) for a while now - we got to >$1M in annual revenues mostly selling to the mid-market, but decided to launch a Free Tier this year.
The problem we are solving is helping marketers turn more underserved leads into revenue through an email AI assistant.
Carrying over from previous years, but we've been building Snapsure (https://snapsure.app) to help photographers find just the right conditions to take better pictures. We're finally "launching" this month with our free tier as we continue to get feedback and scale features.
