Respect to them for having the fortitude and not giving up.
I think you have a great product (trust me, I don't say that often)! It sounds like your biggest problem is distribution/marketing – I'd never heard of Skills before your comment and I've been looking for recruiting software. Perhaps you could do some deal with a job board where companies can choose to have applicants apply through you. Also, it'd be nice if applicants could list their HN profile as well.
Good luck!
It took us 2.5 years to get to product market fit. We raised a seed round and kept burn incredibly low for a long time while we figured things out. There were a couple of product adjustments along to way based on customer demand.
It took us 2.5 years, to reach out first million of recurring sales. It'll take us less than 3 months now to double that. Patience certainly is a virtue.
I hope your software is never taken seriously.
Sorry I don't have a github account or a blog but I was too busy making sure Google search actually works.
