I've always been a B2C founder. I've built an app to 100k+ MAU and sold it to a major company. I'm now building a tool called Modu.io to help businesses collect user feedback, taking directly from my own struggles (I got so frustrated with existing tools that I ended up using a single Google form).
I'm not particularly suffering the switch on the building side, I'm actually enjoying it since I'm more interested in using this tool myself, than I was with the B2C one. What I'm finding myself (sort of) uncomfortable at is the distribution/marketing side. I've launched on a bunch of ProductHunt like websites, ended up first on Uneed yesterday (didn't get much traffic-wise honestly), and bought a couple features on some of them as they were relatively cheap.
I believe collecting user feedback is one of the most important things you can do while building a product. I used to run a B2C app with 100k monthly users a couple years ago, and got so frustrated with existing solutions which were either too complicated or too expensive, that I ended up using a single Google Form. I don't need to tell you how tedious the process of going through all the answers was.
Fast forward to today, I sold that app, and for the last 5 months I've been working on Modu.io , a feedback collection tool that allows businesses and communities to create multiple kinds of feedback modules (suggestions with voting, roadmaps, changelogs, polls, ratings, open questions) and either organize them in a public board, link to them directly, or use them as in-app embeds/popups.
