AI Product Consulting
From research spike to production model. We design AI systems that are observable, evaluable, and grounded in real product constraints — not demos.

Lumière is a product and consulting lab for AI, systems programming, IoT, FinTech, blockchain, and developer tooling. We turn complex technical domains into clean, maintainable products — from prototype to production.

Capabilities
Five disciplines, one standard of clarity.
We work across the stack where the hard problems live — and we ship the same way everywhere: clean abstractions, measurable performance, code your team can own.
Custom Software & Enterprise Systems
Mission-critical platforms with clean domain models and architecture that survives scale, audits, and the next five years of change.
Low-Level, Embedded & IoT
Firmware, edge runtimes, and device-to-cloud pipelines where every byte and microsecond is accounted for.
Developer Libraries & Tooling
Public abstractions, SDKs, and internal tooling with APIs your team actually wants to use.
FinTech, Networking & Blockchain
Ledgers, protocols, and smart contracts engineered for correctness, settlement integrity, and adversarial conditions.
Technical stack
Pragmatic engineering, deep abstractions.
We choose languages for the shape of the problem — not fashion. The result is software that is fast where it must be, and provably correct where it counts.
- 01Performance.
Rust and C-grade systems work where latency and memory are first-class concerns.
- 02Correctness.
Type-driven design in Haskell and TypeScript that makes invalid states unrepresentable.
- 03Velocity.
Python and C# for pace where it counts, without trading away maintainability.

About
A small lab for hard problems.
Lumière is a small, senior team of engineers and product people. We take on the problems most teams route around — the low-level, the high-stakes, the genuinely hard — and return them as software that is calm to operate and easy to own.
We stay deliberately small. There are no layers between the people you talk to and the people who write the code. Who we work with stays private; the standard we hold doesn't change with the logo on the door.
Operating principlesClarity over cleverness
The best system is the one your team can still reason about a year from now. We optimise for the second reader, not the first impression.
Own what we ship
We write code to be handed off — documented, tested, and free of any private dependency on us. Leaving cleanly is part of the job.
Fewer things, deeper
We run a small number of engagements at once, so the people who scoped your problem are the people solving it.
