Their literal tagline is "Work where your mind matters". They advertise to mathematicians, competitive programmers, FPGA engineers, systems programmers, all in search of a non-bullshit job where someone can appreciate their true skills and somehow advance their field's frontiers.

The LLM era is just dissolving this illusion, revealing the more benign truth: they are a financial company with mildly unusual tech needs. Just like Y-Combinator is just a venture capital fund, just like big techs are just a dysfunctional companies... Your work there wouldn't change the world, and if we left our future up to these institutions, we'd spend it in a couple decades of glut, leaving a deindustrialized barren husk for the next generation.

This is clearly an advertisement, so I'd say they're successfully getting their marketing onto HackerNews.

Money.
