Reached 200 registered users in about 2 months

I have been working on Knowledgehunt.co for about 2 months now. It is a free knowledge directory platform that aims to help solopreneurs and first-time founders by surfacing relevant resources. I have spent less than 500$ on this project so far (98% on building the website and close to 0 on marketing).

Today, I suppressed 200 as the number of users and wanted to share my experience of what helped:

1. Before, you could access all the resources without registration. Now, you need to register to access them. I know this is frustrating for some users; on the other hand, we spend dozen of hours searching and curating those resources, so a few seconds of registration is fair, in our opinion.

2. We started 'resource of the day' campaigns on LinkedIn and Twitter, where we post about a specific resource each day, tagging the creators and thanking them. This helped to attract new users.

3. I did cold DM outreach on Twitter to people who were part of a Twitter community called 'Build in Public.' I noticed that 95% of those group members were founders, so I simply introduced KnowledgeHunt to them. Not the best results, but it got us a few users.

4. The most considerable % of our users come from us supporting the community. We are actively answering the questions of indie hackers on Twitter, Reddit, and Quora, thus attracting potential users.

Now, we are building a new website because we validated our central hypothesis: Can KnoweldgeHunt create value for the startup community? - for us, the answer is Yes. What do you think?
