- I built some relationships with my early users on Twitter for free. I did end up spending $33 on ads that were not too effective, however, I learned a lot in the process. If you're curious, I wrote about it on Medium: What I Learned About Your SXSW Experience
- Lowercase Alpha is free (from what I understand) for founders to post on, but you'll have to know someone at Lowercase Capital (eg. @sacca, @mazzeo, @jacksondahl, or @lazalberto) to help you get onto their list. Alpha will send out TestFlight links to their subscribers, who can then download your app & give you feedback on it. Efficient, easy, but you might have to call in a favor to get ahold of someone at lowercase.
