solidSF about
solidSF is a browser-native mechanical CAD company with an owned Rust geometry kernel, native agent tools, and our own model-serving infrastructure.
Founded by Andrew Norris in San Francisco in 2025. The point is not to make another CAD wrapper. The point is to rebuild professional design software so it is fast, private, programmable, agentic, and available in a tab.
Most CAD companies rent the hard parts from someone else. solidSF is built the other way: own the geometry, own the runtime, own the agent loop, and make the product simple enough that a serious engineer can start from a browser.
Mechanical design software got stuck in an old bargain: expensive seats, desktop installs, license servers, locked file formats, and procurement-heavy pricing. That bargain made sense when CAD was a workstation product. It makes less sense when the browser can run WebGPU, WebAssembly, collaboration, payments, vault workflows, and model-driven tools in one place.
solidSF starts with a custom Rust B-rep kernel rather than a licensed black box. The workspace is parametric and feature-tree based: sketches, constraints, operations, drawings, assemblies, CAM, revision history, and private documents by default. The migration path is not dead-mesh import; the goal is editable history, including SolidWorks .sldprt feature-tree replay.
solidSF is a commercial CAD company, but the technical posture is public: ship real infrastructure, let people inspect the work, and avoid asking the market to believe a slide deck on faith.
The agent is not a chatbot parked beside CAD. It is another operator of the same modeling system. It can call registered tools to create sketches, add dimensions and constraints, extrude, cut, fillet, pattern, generate drawing views, prepare CAM context, and validate results against the same product state the human UI uses.
A CAD agent only matters if it can touch geometry. solidSF gives the model structured tools and records the resulting trajectories, so the product gets better as real modeling work happens.
solidSF serves its own agentic model through the rvLLM/vLLM-compatible path, keeping inference close to the tool-calling runtime. The strategy is practical: use frontier models where useful, but make the everyday CAD agent cheaper, faster, specialized, and owned.
Andrew Norris founded solidSF in 2025 in San Francisco after 18 years inside CAD, mechanical engineering, thermal and fluids work, and hard-technology systems.
He is a licensed Professional Engineer in mechanical, thermal, and fluids, an early Atomic Semi engineer, and the builder behind solidSF's first full stack: Rust CAD kernel, browser workspace, backend, Stripe billing, Google OAuth, organization roles, vault, model training pipeline, self-hosted email, CI, deployment scripts, and the CAD agent runtime.
That matters because CAD is not a thin application problem. The kernel, the file migration path, the collaboration model, and the agent interface all touch each other. solidSF is founder-led by someone willing to own those hard seams directly.

solidSF is headquartered in San Francisco, California. The product is live, the workspace runs in the browser, and the company runs on AWS and Cloudflare for production traffic with GPU training and serving capacity behind the agent stack.
We are hiring for the people who want to build the geometry engine, rendering surface, CAM/CAE workflows, deployment systems, and agent loop that can replace desktop-locked CAD.
