Ask HN: Most interesting tech you built for just yourself?

I've built a CRM (https://www.bizzey.com) for myself to automate my accounting / business administration. I was freelancing on the side and noticed that many of the business solutions where either crazy expensive for a single person business or looked like they were made in the 80's.

It has since exploded into fully fledged CRM with all kinds of features you can choose from. I originally built it for myself to keep track of everything expenses, recurring invoices, ... At some point a freelancer saw me working in it and asked what I was using.

Told him what I was working on and he became my first customer, since then it has spread through word of mouth.

This is actually really cool, I may have to give it a shot! Thanks for sharing

Congratulations on your success so far and good luck with it - I just dropped by to say that all the sales pop-ups on your front page are quite intrusive and premature (I'm currently browsing mobile) - I'm trying to read about the features you offer but I keep getting interrupted by invitations for a demo or a free trial. It's a matter of personal preference obviously but I am never pursuaded to buy something by a sales person jumping on me before before I even know what I'm looking at, and that's much more likely to push me away altogether.

I know this sort of thing is tough to get right so I hope a bit of constructive criticism is helpful; overall it's impressive that you've launched a product that people find useful and I wish you all the best with it!
