Reer

What Reer does

Reer is a Palo Alto-based, privately held startup that has built an AI agent platform positioned as the 'agentic layer' for CAD and BIM workflows. The company's core product is a plugin that embeds autonomous AI agents directly inside Rhino (with Revit integration in active development), enabling architecture, engineering, construction, and product design professionals to automate repetitive tasks such as batch edits, parametric variation generation, documentation, tagging, and cross-file coordination. The platform's underlying architecture centers on a proprietary Intelligent Design Environment (IDE) that orchestrates agents across multiple CAD instances, files, and platforms simultaneously while keeping model files local via smart file linkage to protect intellectual property.

The technology stack is purpose-built for CAD's unique constraints, including B-rep geometry, history-based operations, and bi-directional agent-human co-editing, rather than adapted from generic chatbot or tool-calling interfaces. Reer maintains an open-source portfolio of Model Context Protocol (MCP) servers for Rhino, Revit, Blender, Fusion360, SolidWorks, Onshape, and several other CAD tools, with its Rhino MCP server reaching 6,000+ downloads. The company is a member of NVIDIA's Inception Program and has access to Autodesk Technology Centers in Boston and San Francisco, signaling infrastructure partnerships to support compute and CAD ecosystem access.

Commercially, Reer is currently in open beta with a freemium model: the Individual tier is free, the Creators Program grants expanded token limits in exchange for social sharing, and an Enterprise tier is priced at $129/month (with a planned Individual tier at $24/month post-beta). Distribution is hybrid, combining product-led growth through the Food4Rhino marketplace and self-serve website sign-up with enterprise field sales via a 'Start a Pilot' form targeting firms of 1-10 to 200+ employees. The company reports 9,200+ beta users, a 4.9/5 rating on its homepage, and 50+ announced CAD/BIM integrations. Founded as a consumer brand for recyclable 3D-printed furniture, Reer pivoted into AI for CAD and BIM and closed a $550,000 seed round in November 2025.

Core offering

Reer builds an AI agent platform that acts as an "agentic layer" embedded inside CAD and BIM software such as Rhino and Revit (Revit integration in development). Through its Intelligent Design Environment (IDE), the platform orchestrates AI agents that perform parametric design, batch edits, design variations, automated documentation, and in-workspace rendering visualization via natural-language prompts, while keeping models local on the user's machine via smart file linkage. The product is distributed primarily through the Food4Rhino marketplace as a Rhino plugin, with a freemium beta funnel and planned tiered subscriptions.

Product overview

Reer is an AI-powered agentic layer for CAD and BIM, fundamentally transforming CAD into AI-Aided Design (AAD). The product portfolio consists of the core Reer Plugin for Rhino (with Revit coming soon), which embeds AI agents directly into the CAD workflow through Reer's proprietary Intelligent Design Environment (IDE) architecture. The IDE connects multiple CAD platforms, enabling AI to work across files and workflows. Pricing includes a Free Trial (limited beta access), Creators Program (invite-only with higher limits and early feature access), and Enterprise tier ($129/month with dedicated support). The company also maintains open-source MCP servers including Rhino MCP Server for developers wanting to experiment with AI x CAD integrations.

Partnerships

Two partnerships are on record, tiered core.

• Robert McNeel & Associates (Rhino)coreTechnology or Integration · 1 January 2025Rhino is Reer's primary integration platform. Reer has built an open-source Rhino MCP server (6,000+ downloads) and the main plugin is distributed through Food4Rhino. The partnership enables AI agent capabilities directly inside Rhino's parametric modeling environment.
• Autodesk (Revit)coreTechnology or Integration · 1 January 2025Revit integration is actively in development ('Revit Coming' shown on website). Reer has also built open-source Revit MCP server. Once launched, this will expand Reer's capabilities to BIM workflows for architecture and engineering professionals.

Others

• Robert McNeel & Associates (Rhino): Rhino is Reer's primary distribution platform and most important integration partner. It is not a direct competitor in AI, but its roadmap, API changes, and potential first-party AI features directly determine Reer's product surface and access to the Rhino community.

Direct peers

• TestFit: TestFit applies AI and automation to early-stage architectural site and feasibility design, automating repetitive tasks such as unit layout, parking, and code compliance. It shares Reer's core thesis of using AI agents to compress AEC workflows and integrate with platforms like Revit.
• Hypar: Hypar is a cloud platform that turns AEC logic into reusable 'functions' for schematic design, including structural grids, loads, and space programs. Like Reer, it sells to AEC firms seeking to automate the routine parts of design and to coordinate across multiple tools and files.
• nTopology: nTopology is an engineering design platform that uses generative and computational workflows to automate CAD tasks. Like Reer, it positions itself as a modern AI-augmented layer over traditional CAD tools, targeting industrial designers and engineers seeking to accelerate parametric design and reduce manual modeling.
• Finch (finch3d): Finch offers AI-driven building design automation for the schematic stage, generating and evaluating design options inside tools like Revit and Grasshopper. It is directly comparable to Reer on the AEC AI agentic layer thesis and shares Reer's integrations with Rhino and Revit.

Broad incumbents

• Trimble (SketchUp / Trimble Connect): Trimble owns SketchUp and Trimble Connect, both targeted by Reer integrations, and has been expanding AI features across its AEC portfolio. It represents both a channel opportunity and a competitive threat similar to Autodesk.
• Dassault Systèmes (SolidWorks / 3DEXPERIENCE): Dassault owns SolidWorks and the 3DEXPERIENCE platform, both of which appear in Reer's integration list, and is investing heavily in generative design and AI assistants across its CAD portfolio. It competes with Reer for industrial designer attention and could ship competing agents on its own platforms.
• Autodesk (Autodesk AI / Forma): Autodesk owns Revit, AutoCAD, Fusion360, and Civil 3D — the platforms Reer integrates into — and is actively shipping its own AI features (Autodesk AI, Forma/Spacemaker). It is the single most important incumbent threat and the most natural distribution partner, and competes head-on with Reer's agentic vision.
• PTC (Onshape / Creo AI): PTC owns Onshape (cloud CAD) and Creo, both of which Reer lists as integrations, and is adding generative and AI design features to its portfolio. It competes for industrial designer mindshare and could ship first-party CAD-AI capabilities.
• Adobe (Substance 3D / Firefly): Adobe's Substance 3D stack and Firefly generative models overlap with Reer's in-workspace rendering and AI-driven visualization claims. While Adobe is not a primary CAD vendor, it competes for the same designers and is investing heavily in agentic creative workflows.
