Build the thing you were told was too hard to build.
Sindri.SI™. The product development platform with the whole SI suite behind it. Describe what you want to make. Sindri.SI helps you design it, simulates it against physics, materials, energy and cost before anything is machined, checks it against the rules it will meet, and finds a factory that can actually build it. We do not pick your category. If it is physical and lawful, you can develop it here.

The name
The forge that made the gods' tools.
Sindri is the dwarf smith of the Norse stories. With his brother Brokkr he took a wager from Loki and forged, in one sitting, the three finest things the gods ever owned: Gungnir the spear, Mjölnir the hammer and Gullinbursti the golden boar. He did not ask what they were for. He asked what they had to do, and made them to that.
That is the whole idea of Sindri.SI. You bring the brief. We bring the forge: the models, the materials, the simulations and the factories. The other SI products came out of this way of working. Now it is open for yours.
Sindri/Old Norse, often read as “the sparking one”
What it does
The forge that made the gods' tools.
Every stage runs on an SI product that already works in industry. Sindri.SI is the workbench that puts them in one place for a maker rather than a plant.
Design
Design with real materials
Turn a plain-language brief into a specification and a bill of materials, with materials suggested by MalmStoff.SI and their properties, cost and sourcing shown next to each choice.
Simulate
Simulate before you machine
Run the design against mechanical, thermal, energy and cost models from Norns.SI, Logi.SI and Gungnir.SI. Every run is stored with its inputs so a result can always be reproduced.
Make
Find a factory that can build it
Match the design to a global network of manufacturers on process, material, tolerance, volume and certification, get design-for-manufacture feedback before you ask for a quote, and track the first article.
Connected
One workbench, the whole suite.
Sindri.SI does not reinvent simulation, materials or compliance. It calls the SI products that already do those jobs and shows their results on your design, in order, so you can make a decision at each step.
The factory network is global. Which factories you can use, and what you may ship them, depends on the laws of your region and theirs. Sindri.SI applies those rules before a match is shown, and we stay involved in the build to the extent your contract with us says.
Simulate
Norns.SI and MalmStoff.SI
World models for how the product behaves, and material models for what it is made of.
Optimize
Gungnir.SI and Logi.SI
The hard trade-offs in a design space, and the energy and carbon of making and running it.
Comply and live
Heimdall.SI and Idun.SI
The rules the product must meet before it ships, and its life in the field after it does.
Use cases
Anything physical and lawful.
We do not limit the category. These are the kinds of products people bring us.
Robotics and automation
Grippers, mobile platforms, inspection rigs. Mechanics, drives and the software that moves them.
Energy hardware
Battery packs, power electronics, heat exchangers. Thermal and electrical limits checked before the first board.
Medical and lab devices
Instruments, wearables, fluidics. Designed with the regulatory route in view from the first sketch.
Sensors and IoT
Enclosures, antennas, power budgets and the field conditions they will actually meet.
Mobility and marine
Drives, hulls, structures and the fatigue life they need.
Consumer and industrial products
Tools, furniture, appliances, components. Designed for the factory that will make them and the life they will have.
Ways to start
Three ways to work with Sindri.SI.
Every company is set up differently, so there is no price list. Tell us what you run and we will propose a starting point.
Studio
One product, start to first article.
We work with you on one product from brief to a first article in your hands, using the full platform and our engineers where you need them.
- Brief to specification with our engineers
- Simulation runs on Norns.SI, MalmStoff.SI and Logi.SI
- Compliance route mapped with Heimdall.SI
- Factory match, quotes and first-article sign-off
Platform
Your team, our workbench.
Sindri.SI as a workspace for your own product team, with simulation compute, the factory network and our review on request.
- Workspace for your designs and runs
- Simulation compute, metered
- Access to the factory network
- Design and compliance review on request
Programme
A portfolio of products, built together.
For companies developing several products at once. We run the platform, manage the factory relationships and own outcomes as agreed in the contract.
- Dedicated engineering and programme management
- Factory relationships managed by us
- Build oversight through to production
- Hand-off to Idun.SI for life in the field
Tell us what you want to make.
Sindri.SI is offered by enquiry only. Tell us what you run and what is driving the work, and we will reply within two business days, usually with a few scoping questions.
Developing for defence? That goes through Ragnarok.Defence.
