Little time before funding
Little money and time before the next funding round.
Startups
Your first hardware team, from day one.
Go from idea to a board you can order, with an enclosure and firmware, before you hire.
Your problems
No full engineering team
No full electronics, mechanical, and firmware team yet.
First board mistakes cost months
A first-board mistake can delay the product while the team waits for another revision.
Startups
What startups need from Flux.
Parts you can buy.
Flux picks parts that are in stock and compares prices across distributors.
A full hardware team before you hire one.
One AI engineer designs the board, the enclosure, the harness and the firmware.
A working prototype before the next funding round.
Go from idea to a board you can order in one project.
No costly first-board mistakes.
Flux runs circuit simulation, design rule and datasheet checks before you order.
Quotes as you design.
Flux gets quotes from fabricators as the design changes, so you know the cost of each version.
Grow without changing tools.
Your first hires work in the same project, with every change recorded.
End to end
A single AI handles the entire device.
Manage your complete hardware needs in a single workspace. One AI agent drives the process from initial requirements to final export files. Your startup reviews the work along the way.
Project specs
Begin with a written brief, a block diagram, or a formal requirements document.
Component selection and schematics
The AI draws the schematic and sources available parts.
PCB routing
The system routes and places components according to manufacturer limits and your specific rules.
Enclosure and wiring
The AI designs the mounts, enclosure, and internal wiring harness around your physical circuit boards.
Embedded code
The system generates and tests firmware for your new hardware.
Validation and export
The platform simulates changes and verifies rules continuously. It finally produces STEP, IPC-2581, ODB++, Gerber, and the bill of materials.
Proof
“Flux helped kickstart my first PCB design, 50% faster than if I had to use KiCad by myself.”
Melker Wändahl, creator of Tilt Tracker
Model-agnostic AI
The AI models you trust. The engineering tools you need.
We combine advanced AI models with a specialized platform for CAD and EDA. The models provide the logic. Flux supplies the context, workflows, and tools that convert ideas into physical hardware.

- Anthropic
- Google Gemini
- More as they ship
Frontier performance at a 30% lower price.
The Adaptive system divides your engineering jobs into specific tasks. It assigns each piece of work to the right model based on capability and price. Complex choices go to large models. Simple steps go to cheaper models. Parallel execution brings your device together quickly. You interact with a single AI engineer while Flux manages the workload.

Top models in one place
Access the frontier AI models your team relies on directly inside Flux.
Built for hardware engineering
Each model uses our specialized engineering tools, project context, and specific hardware workflows.
Upgrade without migrating
Your startup can use newer models as soon as they launch without changing tools.
Stay vendor independent
Prevent your hardware progress from relying on a single AI provider.
Match tasks to models
The Adaptive feature matches every engineering step to the best model for the task, from complex logic to routine checks.
Kernel-agnostic CAD
Selects the right CAD kernel for every part.
Standard CAD software limits your design to a single geometry kernel. Flux works with multiple kernels. The AI engineer chooses the appropriate kernel for a given piece. It changes kernels if a feature requires it. Every component merges into a single model.
-
OpenCascade
Precise geometry that transfers well to CAM and other CAD programs. Great for multi-part assemblies and machined components.
-
SMLib
Flowing, curvature-continuous surfaces designed for consumer devices and handheld enclosures.
-
Parasolid On request
The core engine for SolidWorks, NX, Solid Edge, and Onshape. This allows native file exchange with those platforms.
Verify surface quality visually. Zebra stripes, curvature maps, and curvature combs prove faces are smooth. They let you check parts before tooling begins.
Verification lab
Simulates and verifies its own work before you build.
Generating a design is only the first step. The AI engineer verifies its output using professional solvers. It then displays the test results to your team.
Test circuit behavior
The AI engineer runs and reviews SPICE simulation for mixed-signal, power, and analog designs.
Electromagnetic analysis
Check antennas, crosstalk, S-parameters, and impedance with full-wave simulation on routed boards.
Thermal testing
Test airflow and heat dissipation on enclosures and boards before fabrication.
Fluid dynamics
Model cooling and airflow inside the enclosure. Verify heat sinks, fans, and vents before building.
Mechanical stress tests
Run finite-element stress analysis on mounts, brackets, and physical enclosures.
Rule verification
Verify manufacturing and electrical limits on all boards and schematics.
Datasheet validation
The system reads part datasheets. It verifies your design against specified limits, ratings, and pinouts.
Orchestration
A single prompt starts an entire AI team.
Give your complete product specs to Flux. The lead AI engineer divides the job into workstreams. It launches parallel project threads, tracks progress, and delivers the results.
Concurrent work
Every workstream operates in an independent thread. The enclosure, main board, and daughterboards develop simultaneously.
Multiple projects
The lead AI triggers tasks in related projects. It monitors everything from a single place.
Automated management
The system watches each thread. It corrects agents that drift from the requirements and gathers the final output.
Your final approval
Modifications that alter board sizes or move interfaces require your sign-off.
Building three daughterboards
Flux creates a brief for every board. This includes mounting holes, outlines, connectors, and enclosure openings. Each board receives a dedicated AI engineer and project space. All three progress in parallel. Flux inserts the completed boards into the main assembly. It then checks connector alignment and clearances in millimeters.
Collaboration
Work with AI, partners, and coworkers in one live space.
Access Flux through your browser. Your startup opens one shared project to view the live design. Everyone edits simultaneously without sending files over email.
-
Real-time co-editing.
AI engineers, reviewers, and engineers share a workspace. You can watch who joins the file and what items they select.
-
Automatic version history.
The platform logs every edit with a timestamp and author. You can view past versions or branch them into new projects.
-
A unified startup workspace.
Keep your design standards, parts, and projects grouped together. Grant your startup team edit, comment, or view permissions.
-
Invite outside contractors, suppliers, and clients.
Send an email invitation for specific projects. Guests receive view, comment, or edit rights for that file only.
-
Contextual design reviews.
Leave a comment directly on the canvas and @mention coworkers. Feedback remains attached to the physical design.
-
Experiment safely.
Duplicate a project branch to explore new concepts. Your primary design stays untouched.
Customizable
Adopts your startup's rules for every new design.
Each startup approaches hardware differently. Feed your standards into Flux, link your internal tools, and let it create custom apps for your projects.
Internal knowledge
Train Flux just like a new hire. Document your preferred parts, lessons learned, and guidelines. Every AI engineer will use this data moving forward.
Custom constraints
Enter manufacturer capabilities and layout rules one time. The platform verifies all future designs against these limits.
Link your tools
Link any MCP server, or provide a key to any web API. You can push firmware code, pull crash reports from field devices, or integrate custom internal software.
Secure API keys
Startup admins supply API keys once. The AI engineer accesses them blindly. Flux attaches these keys exclusively to approved service requests.
Custom project apps
Request a custom utility. Flux will code a live project page. This could be an interactive 3D assembly, a dynamic power budget, or a tracking checklist.
External AI integration
Connect Flux to Cursor or compatible AI agents. These external tools can modify your projects and assign hardware tasks to our AI engineer.

The request, as typed in Flux
“The holder must cover a much taller power supply. Make the bent side flange 40 mm deeper. Keep the 4.4 mm hole in the flange where it is. Then cut five 5 x 30 mm vertical vent slots in the new part of the flange, 15 mm apart and centered on the flange width.”
Import legacy files
Upload 3D models, part libraries, and full projects. Placement, parts, and schematics transfer over easily, along with routing data from most formats.
Keep editing with your AI engineer
Uploaded files are immediately editable. Tell the system to "make the enclosure tighter" or "move the USB cutout 3 cm left". Flux executes the command.
