I'm good at "releasing". I'm not good at deciding what to build (demand) and I'm not good at the marketing side.
My latest project helps you get more followers and increase user engagement on Instagram. It's a Google Chrome extension called Magis. It's currently bringing in $30 per month with $25 per month in fee's for the payment solution. Yay $5 profit; if you don't count my time.

My previous project helped you validate your idea before you create the actual product. Apparently it was a bad idea because all it really seems to do is piss people off. Anyway, meet FauxBuy.
Those are just the last two. I build a lot of stuff that's not profitable.
