About Luminance
Luminance is the pioneer of Legal-Grade™ AI: technology purpose-built to automate and augment every interaction a business has with its contracts. Founded by AI experts from Cambridge University, our mission is to remove the inefficiencies, risks and costs of traditional contract work so legal and business teams can focus on strategic, high-value tasks.
Contracts sit at the heart of every business, governing relationships with customers, employees and suppliers. Yet the processes around them have long been repetitive, manual, and error-prone – an unsustainable model in an era of growing regulation and rising workloads. Luminance was created to solve this universal challenge. Our platform is language-agnostic, fully plug-and-play, and cloud-based, making it accessible to any organisation, anywhere.
Today, more than 700 organisations across 70+ countries rely on Luminance, including leading names such as LG Group, DHL, BBC Studios and AMD. The scale of our customer base demonstrates both the global applicability of our technology and the urgency of the problem we are solving.
We continue to invest heavily in innovation to keep our technology at the forefront of AI development.
Recent breakthroughs include:
- Auto Mark-Up: one-click automatic contract amendment against internal gold standards.
- Agent Lumi: an advanced agentic AI assistant that takes capabilities from “thought to action.”
- Lumi Go: real-time insight into negotiation outcomes.
- Lumi Pro: instant Q&A across an organisation’s full contract landscape.
- Deep Insight: dynamic advice powered by external market data.
The results achieved by customers highlight the tangible value we deliver.
- Hitachi saves over 500 hours annually on contract generation.
- Yokogawa reduced business query response times from seven days to ten minutes.
- Emma Sleep doubled the number of contracts reviewed per quarter
- Proofpoint cut NDA review time by 80%.
- NTT was able to review an 85-page MSA in just five minutes.
Our commercial trajectory is equally strong. Over the past two years we have achieved 6x growth in corporate ARR and 5x growth in our corporate customer base. In 2024, we secured a $40 million Series B funding round, followed by a $75 million Series C in February 2025 – over $115 million raised in under 12 months. This unprecedented investor confidence, including from early customers, reinforces our leading position and the scale of the market need.
Looking ahead, we are focused on expanding adoption across every sector where contracts underpin business activity. With our unrivalled Legal-Grade™ AI, proven customer success, and rapid global growth, Luminance is setting the new standard for how businesses negotiate, analyse and manage their contracts.
