London-based Doubleword (formerly TitanML), a self-hosted inference platform for enterprises, has secured $12M (approximately €10.6M) in a Series A funding round led by Dawn Capital.
Dawn is Europe’s leading specialist B2B software investor, with assets under management of over $2B.
Dawn is primarily an early-stage investor, backing companies from Series A and B, and continuing to fund the top-performing through growth rounds to exit.
Haakon Overli, General Partner at Dawn Capital, says, “Doubleword is the most exciting startup in this space, and we’re extremely excited to be supporting Meryem, Jamie, Fergus, and the team as they take the company to the next level. The team has a market-leading product, and has proven they can flawlessly execute to deliver for global customers. They are scaling a product that businesses need at the right time, with the right expertise.”
The UK company will use the funds to grow its team globally and accelerate growth to solve even more of the inference problem.
What does Doubleword solve?
A UK company is tackling a major challenge in large-scale AI adoption: self-hosted inference.
Inference is when AI provides real-world benefits, like answering questions or creating images. It helps transform AI models into useful business results.
As more businesses adopt AI, having control over inference has become crucial. This is leading to a move towards self-hosted inference systems.
However, self-hosting brings with it the enormous task of building and maintaining a performant, scalable inference infrastructure.
As a result, many teams find themselves trapped in an ongoing cycle of assembling tools, hunting for specialised talent, and continually updating their infrastructure to keep pace.
This is where Doubleword comes in.
Doubleword: Self-hosted AI platform
Founded by Meryem Arik (CEO), Dr Jamie Dborin (CSO), and Dr Fergus Finn, Doubleword is a self-hosted AI platform for businesses.
Meryem Arik, Co-Founder and CEO of Doubleword, says, “Our customers want to build AI-powered applications, not AI infrastructure. We eliminate the heavy lifting of inference at scale so they can go from idea to production faster, without racking up technical debt.”
The company aims to make self-hosting AI as simple as using third-party APIs, helping businesses to take control of their AI technology.
“We ensure that our customers can deploy any AI model with a single click, while always having the latest models and hardware supported – and without being wedded to a single model provider,” adds Arik.
The UK company has already scaled into the US and secured partnerships with Snowflake and Dataiku.
Its end-to-end solution enables enterprises to self-host AI models—open-source, proprietary, or fine-tuned—without having to build, maintain, or optimize complex infrastructure.
By working with Doubleword, enterprises get a production-ready, future-proofed self-hosted inference platform, empowering them to:
Deploy 1 to 1,000 models in their environment easily with a one-click private setup for any open-source, domain-specific, or custom models.
Manage all their deployments in one place, with a centralised control panel for cloud and on-premises setups, including analytics, logs, and alerts.
Scale your AI as you need, using advanced optimisation for GPU performance and flexible infrastructure that adapts to your plans.
Secretary of State for Science, Innovation, and Technology Peter Kyle says, “AI will help us to deliver growth for our economy and new opportunities for people up and down the country, so it’s vital businesses have the confidence to adopt and realise its potential. Doubleword’s work is helping set the standard for how companies can do exactly that – adopting AI quickly and efficiently so they can realise their ambitions and allow their workers and customers to thrive in the age of AI.”
“This is yet another illustration not just of how British-born tech expertise is tapping into AI to help give businesses the world over a unique point of difference, but in the steps we’ve taken to make our tech sector a true global magnet for innovation and investment,” adds Kyle.
