Show HN: I built a privacy first candidate testing app from my bedroom

It took me about 1 year to build the platform and fill it with relevant tests made by experts. The platform is filled with cool features such as anti-cheating mechanisms, Offline mode, coding challenges and anonymous mode.

I am not very good at sales or marketing, so very little users actually became paying customers. I know there's competition, but I've believed that with these cool features I should be able to attract at least a small fraction of the market.

I am looking for answers and feedback. What can I do better to attract more customers?

I've got one feedback to add info about ATS integrations.
