In fact it's a Polish project. They've disrupted dev job boards market in Poland, mainly because salary range strict requirement. IMO their Sales should focus more on bringing international offers because this project have a huge potential.
I believe they have been around for about 4 months, if that - I suppose they want to test and expand the site on local waters first, before marketing internationally more aggressively. It's pretty obviously designed with the global community in mind.
A pity their blog is purely clickbait fluff, genuinely valuable market analysis posts would help with marketing a lot.
