Together AI Raises $800M Series C at $8.3B for an AI-Native Cloud — the Infra Layer Under the Agent Economy

Crescendo AI·low signal

On July 1, Together AI closed an $800M Series C at an $8.3B valuation for its AI-native cloud aimed at open-source model inference and training. While not SaaS disruption itself, it's the picks-and-shovels layer that makes 'bring your own model' agent architectures cheap enough to replace vendor-locked AI features inside traditional SaaS. For builders, cheaper open-model inference is what lets a solo team's agent undercut an incumbent's per-seat AI surcharge.
