Post Up
We're building the Databricks for content production, starting with post. Our orchestration engine coordinates pipelines end to end and turns post-production workflows into a persistent graph of assets and transformations, which are deterministic, verifiable, and nearly instant at scale, powered by a high-performance compute layer. We're building this AI-native from the ground up; ML inference is embedded throughout the pipeline, not bolted on. Stack: On-prem, HPC clusters, distributed storage systems, GPU pipelines, real-time video compute.
