What CircuitHub does
CircuitHub is a US-headquartered on-demand electronics manufacturer specializing in printed circuit board assembly (PCBA) for hardware engineers and robotics companies. Founded in 2012 in South Deerfield, Massachusetts, the company operates a single integrated offering that combines a browser-based software platform (native EDA file ingestion for Altium, EAGLE, and KiCAD, BOM reconciliation, Virtual Build board viewer, instant quoting, order tracking, and Workspaces collaboration) with a physical manufacturing layer called the Grid — a proprietary, factory-scale robotic PCBA system in a 5,000 sq ft South Deerfield facility, teleoperated 24/7 by a remote team and built around AI, robotics, and computer vision.
The business model is predominantly per-order turnkey PCB assembly, with lead-time-tiered pricing in which 3-day full turnkey is the standard (81% of orders ship within three days) and faster options priced incrementally. A discounted ProtoBoard service covers standardized small-batch prototyping, and a Production PCB Assembly Services tier adds mid-volume scheduled runs, consigned inventory management, pre-purchased parts, firmware programming, conformal coating, functional testing, and custom assembly. Pricing is real-time and quote-based rather than published; a shared inventory of 35,000+ common parts and custom-parts management for clients removes MOQ and stocking friction typical of traditional CMs.
CircuitHub is venture-backed, with $48 million in total disclosed funding led most recently by a $28 million Series A in May 2026 from Plural and Sten Tamkivi, alongside prior backing from Y Combinator, Google Ventures, Protolabs, and Hayin Capital. The company has reported cash-flow positive status since roughly 2019-2020, serves 20,000+ engineers, and has shipped 2 million+ boards placing 133 million+ parts. It holds ISO 9001:2015, ROHS-3, IPC-A-610, and UL-supplier certifications, and is expanding from its US base into Europe via a planned first European Grid module.

Revenue model
- Per-Order Turnkey PCB Assembly: Transaction-based revenue: customers pay per assembly order covering bare board fabrication, parts (from shared inventory or sourced), and assembly labor. Real-time quote includes pricing for bare boards, parts, and assembly. Volumes range from prototype qty 1 to 10,000 units.
- Mid-Volume Production & Add-On Services: Scheduled/blanket production runs, consigned inventory and pre-purchased parts management, plus add-on professional services including firmware programming (200+ unit orders), conformal coating, functional testing, and custom assembly.
- Premium / Rush Lead-Time Pricing: Lead-time-tiered pricing where faster turnaround (e.g., 3-day full turnkey as standard; 81% of orders ship within 3 days) commands incremental fees versus standard production schedules.
- Long-Term Cash-Flow-Positive Operations: Reached cash-flow positive status by 2020 and has been growing profitably; ongoing revenue from repeat customers and growing engineer base (20,000+).
Pricing tiers
| Model | Billing | Price |
|---|---|---|
| Other | Pay-as-you-go | Quote-based per-order pricing with real-time instant quotes for PCB assembly; no publicly disclosed price list. |
| Unit Pricing | Pay-as-you-go | ProtoBoard service: discounted pricing for small-quantity quick-turn orders meeting defined spec (1-10 units, 1-4 layers, ENIG, 1.6mm, 1oz, FR4, etc.). |
| Usage-based | Pay-as-you-go | Lead-time-tiered pricing: 3-day full turnkey as standard (81% of full turnkey orders ship within 3 days); faster options priced incrementally. |

CircuitHub product offering
Product offeringCore offering
CircuitHub provides on-demand electronics manufacturing services for printed circuit board assembly, enabling hardware engineers to upload native EDA files (Altium, EAGLE, KiCAD) and receive instant quotes, BOM reconciliation, and produced boards in days rather than months. Production is executed by the proprietary Grid, a factory-scale robotic PCBA platform that combines AI, robotics, and computer vision, supported by a shared inventory of 35K+ common parts and serving prototype to 10,000-unit batch volumes.
Product overview
CircuitHub operates a single, integrated platform-plus-factory offering rather than a suite of independent products. The CircuitHub Platform is the unified software layer — an on-demand, browser-based PCB assembly workflow that handles native EDA file upload (Altium, EAGLE, KiCAD), BOM reconciliation, the Virtual Build board viewer, the Instant Quote tool, Workspaces for collaboration, and order monitoring. Underneath that software layer sits The Grid, CircuitHub's proprietary factory-scale robotic PCBA manufacturing system in Massachusetts, which produces 1.57M+ boards and 87.4M+ parts with 81% of full turnkey orders shipped within 3 days. Layered on top are service tiers: ProtoBoard for standardized quick-turn small-batch assembly, and the broader Production PCB Assembly Services (mid- to higher-volume runs, scheduled blanket orders, consigned inventory, firmware programming, conformal coating, functional testing, and custom assembly). The CircuitHub API exposes account data programmatically, and complementary content offerings like the Pick, Place, Podcast and the CircuitHub Changelog support the engineering audience around the platform.

- The Grid: Proprietary factory-scale robotic platform for automated printed circuit board assembly (PCBA). The Grid is described as a factory-scale robot that "looks more like a semiconductor fab than a contract manufacturer" and is operated teleoperated 24/7 by a remote team with AI increasingly doing more of the work.
- ProtoBoard
Products and services
- CircuitHub PCB Assembly Platform On-demand, software-driven PCB assembly platform that lets engineers upload native EDA files (Altium, EAGLE, KiCAD), reconcile BOMs, run a Virtual Build board preview, receive instant interactive quotes, place orders, and monitor production in a single browser-based workflow. Designed for hardware engineers, robotics companies, and small businesses needing prototype to 10,000-unit batch production.
- The Grid Automated PCBA Manufacturing System CircuitHub's proprietary factory-scale robotic PCBA manufacturing system located in a 5,000-square-foot facility in South Deerfield, Massachusetts. Fully automated and teleoperated 24/7 with AI-assisted operations, the Grid produces prototype PCBAs in 2-3 days and serves as the production backbone for the on-demand electronics manufacturing offering, using AI, robotics, and computer vision to perform physical PCB assembly.
- ProtoBoard Service Low-cost, quick-turn PCB assembly service for small-quantity orders (1-10 units) that meet a defined set of standardized specifications (1-4 layers, ENIG, 1.6mm, 1oz, FR4), delivering full turnkey PCB assemblies in as fast as 3 days with 100% USA manufacturing. Orders not meeting ProtoBoard specs automatically fall back to the standard service. Designed for prototyping and low-volume runs.
- Production PCB Assembly Services Mid- and higher-volume PCB production services offered on top of the core platform, including scheduled/blanket batch orders, consigned inventory and pre-purchased parts management, firmware programming (200+ unit orders), conformal coating, functional testing, and custom assembly for advanced requirements. For hardware and robotics companies scaling from prototype to production.
- CircuitHub API Application Program Interface that allows customers to access their CircuitHub account data programmatically. Usage is governed by the API terms in the CircuitHub Terms of Service; abuse or excessively frequent requests may result in suspension. For engineering teams integrating CircuitHub order, parts, and project data into their own tools and workflows.
