Solving the growing inference problem
When the world’s attention turned to AI models, we focused on the invisible layer that makes them useful: inference. In 2022 — before ChatGPT and before the hype — we identified a critical gap the industry was overlooking. Training models was exciting, but making them run efficiently, reliably, and securely at scale? That was the real challenge.
We built Doubleword to solve this problem from the ground up. Inference is a high-leverage layer: when it fails, costs soar, systems break, and innovation slows. When it works, everything else just flows. Our platform allows organizations to deploy AI — from chatbots to cancer detection models — inside their own environment, without needing to become infrastructure experts. We turn complex inference tasks into secure, hassle-free deployments, giving teams full control without the pain of scaling.
Bringing deep technical research to global enterprises
Our foundation is cutting-edge inference research. Doubleword was founded by inference researchers Dr. Jamie Dborin and Dr. Fergus Finn, alongside Meryem Arik, to bring state-of-the-art techniques into enterprise environments.
Before vLLM became what it is today, our team had already built a best-in-class inference engine, pioneering approaches like spacelike speculative decoding and serverless LoRA serving. Today, we’re pushing the boundaries of batched inference — an under-explored but mission-critical workload for large-scale AI — while sharing long-form technical content to advance the field.
This blend of deep research and real-world engineering is what sets Doubleword apart. We’re working with leading enterprises across pharma, manufacturing, and finance, and partnering with NVIDIA, Snowflake, Dataiku, and HPE to make self-hosted AI deployments seamless. Backed by Dawn Capital and top angel investors, with a $12M Series A, we're building the best inference team in Europe — fast-moving, technically fearless, and ready to shape the future.
