A deep tech startup called Itera has come out of stealth with a prototype of what it describes as the world’s first fluid circuit board — a platform that lets hardware engineers test and modify electronic circuit designs using real components in real time, collapsing iteration cycles that currently take weeks into a matter of minutes.
The company announced $12 million in seed funding from Upfront Ventures, Costanoa Ventures, and Colle Capital alongside the product reveal.
The Problem: PCB Prototyping Is Stuck in the Past
Traditional printed circuit board prototyping forces engineering teams to wait two to six weeks per design iteration. Each cycle burns hundreds of thousands to millions of dollars, contributing to an estimated $50 billion in direct annual spending on electronics development globally. The bottleneck is fundamental: conventional PCBs are permanent. Once fabricated, changing the design means starting over.
Itera’s approach attacks that constraint directly. Using a patented architecture built around glass and liquid metal, the company’s fluid circuit board allows circuit rewiring in less than a minute — without scrapping the board or waiting for a new fab run.
Real Components, Not Simulation
The distinction Itera draws most sharply is against simulation software. EDA tools can model circuit behavior, but they cannot replicate the real-world performance of actual components under actual electrical conditions. Itera’s substrate hosts the engineers’ own components, producing real electrical behavior rather than modeled approximations.
The platform also allows engineers to probe any internal circuit node — not just the test points a traditional PCB exposes — giving signal visibility that conventional prototypes cannot match. The company claims iteration cycles up to 1,000 times faster than current practice, compressing months of development into days.
“Software developers have been able to write code, test, and iterate in real time for decades,” said AJ Cooper, CEO and Co-founder of Itera. “Hardware has always been hard because it is permanent. Changing it requires time and money. Itera is making hardware easy.”
Electronics-as-a-Service Delivery Model
Itera does not ship hardware to customers. Instead, the company operates through an Electronics-as-a-Service model: customers’ designs are assembled using their own components on Itera’s multilayer substrates at secure, U.S.-based testing centers. Engineers modify and test their hardware and software remotely until they have a validated design ready for manufacturing.
The model positions Itera as the sole source of actual electronic performance data across the development cycle — a data asset with potential value well beyond the testing workflow itself. The domestic testing center infrastructure also aligns with current momentum around reshoring, supply chain resilience, and data sovereignty requirements in defense and enterprise procurement.
Early Traction and Market Positioning
Initial production capacity is already reserved by a top-five global automotive OEM and defense contractors. A leading hyperscaler and multiple chipset manufacturers are actively evaluating the technology through hands-on demonstrations.
Mark Suster of Upfront Ventures drew the comparison to cloud infrastructure: “Itera brings an AWS-like solution to testing hardware and this can dramatically lower costs for startups and incumbents alike.” The analogy is apt — the shift from owning physical servers to consuming compute on demand restructured the economics of software development. Itera is attempting an analogous shift for hardware iteration.
Whether the fluid circuit board scales beyond the prototype stage and into high-volume production workflows will determine how far that analogy holds. But the core proposition — eliminating the wait state between design and test — addresses a genuine structural cost in electronics development that has remained largely unchanged for decades.
