Looks like WP – BuiltWith shows WordPress and Elementor as of Feb 2020, and Elementor classes are visible via inspector
There’s no way to see which theme it is (afaik), but it’s using Elementor, so it probably wouldn’t matter which theme it uses if you’re just looking to emulate its appearance.
Also worth noting that even when you use the same theme as another site, there are a million different ways in which a theme can be customized, so going for same/same is generally an exercise in futility. And the internet would be awfully boring if every site looked the same 🙂
