Ask HN: Should I pay for marketing to this B2C SaaS product? (~8% paying rate)

I built an app for myself to apply for jobs and I got an offer. Later I turned it into a desktop app with a $10 subscription per month. Current I got around 300 users and 8% of them paid. If including churned ones that is 10%, which is expected since these users have found a job.

Currently, this is purely organic. I'm wondering if I should start to pay for some ads or influencers to boost it...let me know your thoughts!

Here is the app: https://jobhuntr.fyi
