Agents are eating the economy, but it’s still the early days. Token useage is increasing 2,500% year over year, agents token consumption is growing 7x faster than humans, and adoption of agentic systems is on the rise across professions. All signs point to these trends continuing, as agentic workloads become irreplacable across software, cybersecurity, legal, finance, HR, sales, and science tasks. We are building the foundation.

Subconscious is an inference platform specifically designed to power long-running agents. For tasks that consume 200k+ tokens, our inference system delivers unparalleled speed, accuracy, and cost efficiency. As agents proliferate, Subconscious will be a provider in every agent stack.
