    We're thrilled to announce our $30M Series A at a $300M valuation led by @altosvc, and that we’ve since surpassed $100M in annual revenue run rate.

    AfterQuery post-trained GPT-OSS-20B using Harbor + Tinker and saw a 14% bump on TB2 performance. Love seeing people pick up Harbor for more than just evals.
