YC - Love the blog post intro format. If you offered a daily email with new YC company descriptions I would subscribe (just subscribed to weekly). I've invested in over 100 startups--this is more than curiosity.
Note: weirdly high number of coffee and alcohol brands.
I have done some $1,000 deals at angel.co
fundersclub.com used to allow some $1,000 deals (and I did a few), but now the minimum seems to be more like $3,000.
