- I tweeted random things I learned about running a business, as I learned them
- I tapped my personal network on LinkedIn to find out what folks were currently using, and how they were dissatisfied
- I charged way too low and attracted un-ideal customers
- I made a free tier to compete with other providers that also charged way too low
- I wrote changelogs for every big feature
- I wrote docs for every feature
- I kept a mailing list where I would update folks about the product's progress
- I kept a mailing list where I would update folks about running the SaaS
- I talked about OnlineOrNot on Reddit, Hacker News, in the aim of inspiring people to launch their idea in a highly competitive space
- I shared OnlineOrNot on popular lists (Product Hunt, etc)
- I made landing pages that resonate with folks looking specifically for my type of product
- I built features customers asked for
- I would spend one week marketing, followed by one week coding, and repeat
- I was extremely responsive to customers via email and chat
- I kept improving the product, adding features, and revisiting features
