Collinear powers leading AI labs and Fortune 500 enterprises with high-signal post-training datasets and RL environments, helping teams improve model quality faster and at lower cost.
We simulate realistic, multi-turn user and adversarial scenarios to uncover how models fail in production, then turn those failures into curated data and reinforcement learning environments for CPT, SFT, and RL. The result is faster convergence, stronger robustness, and measurable gains where it matters most.
Collinear is a VC-backed startup serving frontier labs and F500 enterprises deploying real-world AI systems at scale.
