Careful AI, that shows its working.

Cosmosine Labs builds forecasting, optimization and agent systems whose numbers you can check, and the apps and physical products around them. Small studio, long horizons, and a few client projects alongside our own.

Client work

Work with us

We take on a small number of client projects alongside our own, and bring the same care to both. With AI at the centre, here is what that work does for you:

  • Know what is coming, and why. Demand, revenue and capacity forecasts that show their working, so your team trusts them enough to order stock, staff shifts and plan cash by them. For one-off questions, forecasting agents give you the odds and the reasoning behind them.
  • AI you can sign off on. Copilots and agents for analysis, reporting and planning that compute every figure with code they ran and show it, so a number that reaches your board or your clients has been checked, not guessed.
  • AI your customers trust with their data. Features that run on the phone or in the home, so personal data never leaves it: less compliance risk, no per-use cloud bill, and it works offline. Built to be safe for children when they are the audience.
  • Better decisions on price, stock and schedules. Pricing, inventory, scheduling and supply planning, modelled end to end and tested against your own history, so you see the likely gain before anything changes.
  • From idea to something people use. iPhone, Android and web apps, and physical products, taken from first sketch through launch and support by one small studio, so nothing gets lost between design, engineering and manufacturing.

Behind the work is PhD-level research and more than a decade of building AI, forecasting and optimization systems that run in production at global scale, and of leading the teams of scientists, engineers and product managers who deliver them.

Tell us what you're trying to build and where it stands today. We reply within two working days, and after that we're just a call away whenever you need us. No account managers, no hand-offs: you talk directly with whoever is building it.

Universe of AI & Mathematics

Cosmos, meet sine

The name joins cosmos and sine: a universe of AI and mathematics. A galaxy is patient and enormous; a sine wave is small and exact. Adjust the wave below and watch the spiral follow it.

What we work on

One studio, three disciplines

AI, software and physical goods share more than people expect: all three reward careful specification, early prototypes, and someone who cares about the last detail.

APPLIED AI

AI & machine learning

Machine-learning, forecasting and optimization systems, and newer work with large language models and agents. Built to run in production, not just in a demo. Some of it becomes a product; most of it makes the products better.

  • Forecasting & optimization
  • LLM & multi-agent systems
  • Private by design
SOFTWARE

Applications

Software for phones and the web, from first sketch through release and everything that follows it, with AI where it genuinely helps. Design, engineering, and support sit with the same people, which keeps decisions honest and changes quick.

  • iOS, Android & web
  • Private by default
  • Supported after launch
PHYSICAL GOODS

Products

Physical goods designed in house and produced with manufacturing partners. The discipline is the same as software: specify carefully, prototype early, and hold the details that are easy to let go of.

  • Designed in house
  • Made with trusted partners
  • Prototyped before promised
How we work

Fewer things, done properly

We would rather ship one considered thing than five that need explaining.

Most of what we build starts as a question we cannot stop turning over: how something should feel to use, why a familiar object is worse than it needs to be, what becomes possible when a tool anticipates rather than waits.

We keep the loop short. The same people who sketch a thing write it, test it, and answer for it once it is out in the world. That is a constraint on how much we take on, and we treat it as one.

Principles

Privacy is a design decision

The simplest way to protect people's information is not to collect it. Where we can build without it, we do.
