AI made building faster. Great product design still takes judgment. We’ve built and sold companies. Now we bring that experience to yours.
We design. We code. We build shared systems so your team can experiment, learn, and ship.

Your Frontier AIDesign & Engineering Lab

Meet your product design and engineering team.
Building brands, products, and the systems behind them.
Helping you move faster, from your first idea to enterprise transformation.

    A Shared Way to Build

    Try the Idea Find the Direction

    A working prototype gives your team something to experience together. See where people hesitate, what feels clear, and what deserves to move forward.

  • Document, Prototype, Govern, BuildWith the framework, Document supplies the shared system, Prototype explores working directions, Govern resolves quality, and Build ships the result and returns learning to Document — a continuous loop with two pieces of work moving through it.Document PrototypeGovernBuildWith the framework

    One continuous loop

    Every Step Leaves You Stronger

    Document the foundations. Prototype the possibilities. Govern the quality. Build the chosen direction. Carry what you learn into the next cycle.

  • One data layer across every environmentThe Data Layer defines colour, spacing, radius, type and motion as structured data. Prototype code reads it as CSS variables, production as native tokens, Figma as Variables, and agents as names, roles and legal values — every environment at once.Data layerColourSpacing RadiusTypeMotionPrototypeCSS variablesFigmaVariablesProductionNative tokensAgentsRoles · valuesThe foundations

    One Source Every Surface

    Your colour, type, spacing, and motion come from shared foundations. They carry through Figma, prototypes, production, and the instructions your agents use.

  • The whole team explores working directionsFounder, PM, Engineer, Designer, Stakeholder and Support each send the directions they explore into one shared space. They arrive one at a time, and as the possible directions fill the screen the newest push the oldest out.Founder PMEngineerPossible directionsDesignerStakeholderSupportDirections from the whole team

    Give Good Ideas More Places to Start

    Your founder sees an opportunity. Support sees a recurring problem. Engineering sees a better path. Shared foundations help the whole team turn those perspectives into working directions.

    We review each direction through customer needs, business priorities, and technical constraints. Then we refine the workflows, states, and details that make the whole experience work.

    Your Next Release Gets a Head Start

    Useful patterns return to the system. Decisions stay available. What your team learns today becomes something it can build on tomorrow.

“We used to measure new interactions in months. Now we measure them in days. Lumenridge’s product sense and craft gave us the foundation, and their design system and harnesses made continuous design our default. Everything we ship feels modern from the first release. Lumenridge doesn’t hand over screens. They hand over momentum.”

Ambient UI
The Product Design Harness in action

Ambient UI is our open-source library for adding AI assistance to your product’s existing workflows. Working code your team can explore, use, and build on.

Orb

The Orb rests at the edge of the page: one small presence that says the assistant is here without asking for attention. Summon it and it opens into whatever the moment needs, then folds back to a point.

“For the first time, we could take an idea and see a designed, polished experience within minutes. Lumenridge brought the craft to make those prototypes good enough to learn from, then carried what worked into a shared language for our product and brand. What stood out just as much was their genuine care for what we were building.”

The Approach

Your Product Design Team
for the AI Era

More people can build an interface today. Knowing how it should work takes experience.

Product design connects what your customers need, what your business is trying to achieve, and what the technology makes possible.

We bring depth in product design and experience building companies. We design workflows and interactions, prototype directly in code, and test with the people who will use them.

Your team gets an experience it can feel, feedback it can act on, and working foundations engineering can build from.

“We see Lumenridge as an extension of Grayscale. Our portfolio companies are deeply technical, so our design partner needs to understand the technology behind them. That technical depth is Lumenridge’s biggest asset. There are many design studios, but very few can work with the kind of companies we back. This is where Lumenridge stands out.”

The Team

We’ve Been Founders
We Understand What’s at Stake

We’re a team of founders who’ve built and sold companies. Our journey in AI began in 2020, years before it became part of everyday work.

We understand the decisions around your product. What to build. Who it serves. How it reaches the market.

Product design sits at the centre of our work. We bring that company-building experience into the workflows we shape, the code we write, and the decisions we test with your customers.

Our approach

We use
Design as
a Strategic Tool

Connect your business goals to the product people use.

We bring product strategy, interaction design, and engineering together to make complex software clearer. Then we carry that clarity into the way you bring your product to market.

Make Complex Work Feel Clear

Help people find their way through your product. We design the information, workflows, and interactions that turn complex capabilities into an experience people can use.

Bring Native AI Behaviour

Introduce new workflows and AI capabilities into the product your customers depend on. Thoughtful interactions help people understand what is happening and stay in control.

Designed by Us Built by Us Ready to Build On

Our design engineers write your design system and prototype directly in code. Your team and customers can use the experience, test the interactions, and help shape what comes next.

Product managers and customer-facing teams can experiment with the same components and design guardrails. Engineering can build from the working code, reducing the work needed to recreate the design.

“Lumenridge’s framework, processes and patterns aren’t shortcuts. They’re years of craft and study, sharpened by riffing with collaborators like us and distilled into a reusable toolkit that genuinely accelerates design. Somehow, it amplifies human instinct and taste rather than replacing it.”

The Growth Death Zone

You’ve built traction. Hired a team. Created a product customers depend on. Yet every next move takes more effort.

More features. More handoffs. More decisions pulling in different directions.

Think of this as the growth death zone: your ambition is starting to outgrow the way your company builds.

This stage calls for people who understand the company around the product. Your customers, market, business priorities, and engineering constraints all shape the right experience.

AI makes product judgment more valuable. Building a screen is easier. Deciding what belongs, how it behaves, and whether it helps your customers takes practiced design expertise.

That’s where Lumenridge fits. Experienced product designers with founder perspective and the ability to build. We research with your customers, prototype in code, and create the systems that help your whole team move forward.
