Just read on Hacker News today about Font Awesome 5 coming out in May 2017. They launched a Kickstarter campaign, and while Font Awesome 5 will be free for everyone when released, there will also be a Pro version you can pay for and get more features including:
1000+ more icons than Free version
SVG icon framework
Icon Font Ligatures
If you back it while in Kickstarter you can get a Personal / Small Business License for $40, but the Early Backer price is $20. This price reduction goes away about 64 hours from the time of this post. There are other pledges you can make for swag, corporate use, or even have them put in custom logos (including company logos). You can get more details in the link below.
