MVP - ProductHunt began as a mailing list using Linkydink.
Private Beta - Email link to supporters and product influencers for feedback on wireframes and get them excited.
Quiet Beta - Iron out bugs and keep getting feedback with high interaction
Public Launch - PandoDaily, and FastCompany articles came out and ProductHunt emailed all early adopters with two specific asks:
Post a Product - have a healthy level of activity when upon launch
Share the Article - To maximize exposure, we asked early adopters - many who have a large following and influence - to share the article. To make it even easier, we provided a “click to tweet” link that opened Twitter with a pre-created message.
The Manual Slow Growth - Found influencers and good contributors to community via Rapportive and Intercom.io and reached out to them personally to open lines for future feedback, referrals to product people and funding.
