Monte (YC S25)

Today we're excited to announce Monte. We're building the post-training platform to enable every company to train proprietary AI models on their own work. Your agents do real work every day. The model behind them never learns from it. Monte partners directly with your team to train the best model for your specific work. We use our platform to post-train open-weight models on your tasks, deploy them to serve your traffic, and continuously improve them based on real usage. If your team is ready to train your own models, we'd love to talk. @trymonte_ai
