Git for hardware - now with an AI reviewer reading your schematics before the factory does.
Above: a leaf wired with PCB traces. Botany meets circuitry, which is roughly the whole pitch.
They will mark it up by hand. Someone will reply with a screenshot. A capacitor will go missing in the back-and-forth, nobody will notice, and three months later a fabricated board will fail a test it should have passed in a meeting. This is how a surprising amount of the physical world still gets built. AllSpice.io exists because two founders found that genuinely unacceptable.
Today AllSpice is a hardware development platform used by electrical engineers, PCB designers, and hardware teams at companies from scrappy startups to Meta, AWS, Dell, Cisco, and Bose. It does for circuit boards what GitHub did for code: version control, side-by-side visual diffs, pull-request-style design reviews, comments anchored to the design, and an audit trail you can actually defend in a compliance review. In June 2025 it closed a $15M Series A, pushing total funding to $25M.
Co-founder Kyle Dumont ran into the wall firsthand while building electrical and software teams at a 3D-printing company. The design tools that hardware engineers depend on - ECAD suites for schematics and layouts - barely talked to each other. Connecting a new system meant hours of re-keying the same data by hand, which roughly cancelled out the reason you adopted it.
The result is a discipline where "review" often means a senior engineer squinting at a printout, where changes between revisions are tracked in someone's memory, and where a single overlooked pin can trigger a respin that costs weeks and real money. The irony writes itself: the people building the most advanced machines on earth were coordinating it all like it was 1998.
Valentina Ratner and Kyle Dumont met in the fall of 2018, in the first cohort of Harvard's MS/MBA dual-degree program. Ratner had come from Amazon, where she worked on internal productivity and project-management tools and developed a taste for getting teams to actually adopt good software. Dumont brought the hardware scars from iRobot and Voxel8.
For a semester they kept circling the same idea: what would the physical world look like if hardware could be developed with the ease and speed of software? They went looking for the tool that already did this. It didn't exist. So in 2019 they built one and named it after allspice - the single spice that tastes like a whole rack of them, which is a tidy way to describe one platform that ties many design tools together.

AllSpice doesn't replace the ECAD software engineers already love. It sits on top of it - ECAD-agnostic - and adds the layer hardware never had: collaboration, review, and version control that understand what a schematic and a layout actually are.
Git-based revision control with side-by-side visual diffs of schematics, layouts, and BOMs. In-design comments, redlines, checklists, role-based permissions, and compliance-ready audit trails - including ITAR hosting.
An AI reviewer that reads a design and flags real problems: misconfigured pins, swapped TX/RX lines, missing capacitors, component derating. It also auto-writes the paperwork - power tables, spec sheets, theory-of-operation docs.
Continuous integration and deployment workflows borrowed straight from software, so checks run automatically on every design change instead of living in a senior engineer's head.
Plugs into native ECAD tools (KiCad and others), Git platforms, and project trackers - so hardware and software workflows finally share one source of truth.
Ratner and Dumont land in the first MS/MBA cohort and start picking at the same problem.
The pair set out to build "Git for hardware" from Boston. Later a Greentown Labs member.
A $6M raise (Root Ventures, Flybridge, Benchstrength, Bowery Capital) funds CI/CD for hardware and early AI work.
Meta, AWS, Dell, Cisco and Bose join; the platform passes 100,000+ design reviews.
Round led by Rethink Impact brings total funding to $25M; the DRCY AI agent exits private beta.
AllSpice's customers cluster where a hardware mistake is least forgivable: aerospace, defense, autonomous vehicles, robotics, medical devices, and automotive. When a respin costs weeks and a field failure costs more than that, catching the error in review stops being a nicety.
The stated goal is data transparency and automation that make agile hardware design possible - so the loop of "design, review, fix, ship" runs as fast for a circuit board as it does for a web app. The wager underneath it: the next wave of physical products is bottlenecked less by physics than by coordination.
That's also why the AI bet matters. Every review, comment, and diff on the platform is structured data about how good hardware gets made. Point a capable model at that, and you get a reviewer that doesn't get tired on the four-hundredth schematic of the quarter.
On AllSpice, that moment looks different. The change opens as a review. The diff highlights exactly what moved. DRCY reads the schematic and notes, quietly, that a capacitor is missing and a pair of signals looks swapped. A teammate comments on the design itself, not on a screenshot of it. The whole exchange is logged, versioned, and ready for the next audit. Nobody re-keys anything by hand.
None of this makes hardware easy. It makes hardware reviewable - which is the part that was quietly broken for decades. As more of the world fills up with autonomous, connected, regulated machines, the teams that catch the missing capacitor in a meeting will simply ship better products than the teams that find it in the field. AllSpice is betting that's most teams, eventually. The PDF, with any luck, retires.
