Overview
Streamstraight is a YC Winter 2023, San Francisco-based developer-tools startup that provides a durable, serverless persistence layer and SDKs for resumable LLM/AI streams. Its product is built to let teams move long-running AI generation to async jobs, replay interrupted streams, and let multiple clients tail the same response without building the stream-state infrastructure themselves.
