Malted builds specialised AI systems for financial institutions. Our products combine advanced language technology with deep domain understanding to help firms make faster, more accurate and more accountable decisions.
We focus entirely on financial services, working with leading banks, insurers and regulators to turn complex reasoning into clear, dependable intelligence.
Our flagship product, Malted Pulse, provides AI that reasons transparently and can be inspected, governed and tuned to organisational policy.
We’re a small, highly technical team based in Edinburgh, combining deep machine learning experience with a rigorous approach to product design and engineering. We believe that making AI systems understandable isn’t just an ethical necessity, it’s a competitive advantage.
