Ask HN: Trying to figure out if this company is related to Y Combinator?

I can't find any mention of curve.fi (a DeFi DAO/company that specializes in efficient stablecoin trading) on the list of companies [0] but they had submit a hiring thread to ycombinator [1] back in 2021.

Is curve.fi backed or somehow related to ycombinator or can anybody post a hiring thread to HN?
