AnatoliiD / Another Failed Startup Lessons Learned in the B2C Space
Created April 15, 2016 18:55 — forked from jay-johnson/Another Failed Startup Lessons Learned in the B2C Space.md
1) Start by solving a problem with a well-defined customer first
2) Don't rebuild what already exists
3) Don't spend time budget-gaming ec2 instance types
4) Publish a site that allows signups immediately (before anything else gets built)
5) Buy a simple web app package that bundles a ton of pages for example: http://lit-coast-9918.herokuapp.com/react12/index.html
6) Focus on just one customer type and just one problem (KISS)
7) Engage 100 journalists 2 months before you launch (muck rack / pressfriendly.com and or pay someone to do it). Figure out and pitch the story to them before you reach out to them.
8) Use fiverr and pay a bunch of bloggers/copywriters to publish and blog a ton of stuff and budget it for at least 6 months
9) Start using adroll sooner
10) Minify and compress your javascript (I used http://django-compressor.readthedocs.org/en/latest/)
