Could see the first part in a buildup, but then remaining even more lowpassed than at the very beginning as a background synth when the beat drops in a tech house.
It's a nice saw. Pretty simple to make a standalone saw; just some detuned oscs, sdetunes, and eq to your desires. The harder part comes when trying to fit it in a track, especially when the spectrum is already saturated.
The first part already sounds a little much when the filter opens up and would probably be difficult to mix into a track. The arp in the second part is nice and smooth, and I like that the bass isn't detuned.
