WHY IT MATTERS
Long-running agents can be valuable but are especially expensive because they process huge amounts of context over many steps, and Subconscious says its compression and caching can make 200,000-plus-token tasks up to 2x faster, extend effective context beyond 5 million tokens, and cut costs by up to 80%. Its $5.1 million raised across pre-seed and seed, led by MassVentures, funds a cloud and on-premises inference platform aimed at making these agents economical for engineering teams and enterprises.
