ALLSPICE FOUNDER
“Finally bring your collaboration methods into the 21st century”
Every software developer today lives inside GitHub or GitLab. Version control is no longer a best practice – it's the air the industry breathes. AllSpice took that same infrastructure and rebuilt it for hardware engineers.
The platform is a git-based collaboration layer purpose-built for electronic device design. It maintains structural compatibility with GitHub, GitLab, and Bitbucket – those platforms can serve as backup storage – but its real value is what it adds on top: native understanding of the file formats hardware engineers actually use.
Where GitHub renders a diff as lines of changed code, AllSpice renders it as a visual overlay on circuit schematics, highlighting exactly what changed in the design. Engineers can annotate any region of a schematic directly, request feedback from teammates, and manage a review-and-approve workflow that mirrors the pull request model developers take for granted.
The platform also supports review checklists – templates that walk team members through a structured evaluation of a proposed design change. The goal is the same as a code review checklist: make sure nothing critical slips through.
Access is split between editors ("committers" in GitHub terminology, people who can push changes) and everyone else (comment-only). External reviewers can be brought in via a shareable link and participate directly in the browser without needing a full account.
Pricing follows the editor-seat model: $64 per editor per month for small teams, $125 per editor per month for the enterprise tier with expanded authentication and support.
AllSpice has raised $6M in its most recent round, bringing total funding to $9.8M across three rounds.
"Finally bring your collaboration methods into the 21st century" is AllSpice's pitch to hardware engineers – and it points to a real gap. Modern collaboration tooling has saturated software development but has barely touched adjacent technical disciplines.
AllSpice isn't alone in this space. A [related review](/review/novoe-ponjatie-pahnet-novymi-dengami) covered Async, a platform for async voice messaging as a replacement for synchronous standups. The pattern is consistent: collaborative tooling designed for distributed, remote teams is moving into industries that still run on email threads and in-person meetings.
Other examples worth noting: Digs built a collaboration platform for construction projects and raised $7M in its first round; Along tackled contract redlining and raised €1M; ResearchHub applied the model to academic publishing and closed $5M, co-founded by the creator of Coinbase.
What's notable about AllSpice specifically is that it didn't try to reinvent the collaboration primitive. It built a specialization layer on top of git – the most battle-tested collaboration mechanism in existence. That's a much shorter path to credibility with skeptical engineering teams than asking them to adopt a new paradigm from scratch.
The async angle matters here too. Hardware engineering teams are increasingly distributed across time zones, and the traditional response – more meetings – doesn't scale. AllSpice's review workflow is inherently async: reviewers comment on published designs on their own schedule, and the conversation lives in the design artifact itself rather than in a calendar invite.
AllSpice, Digs, Along, and ResearchHub collectively suggest a replicable formula: take a technically conservative discipline that still organizes collaboration through meetings and email, and build a git-based async collaboration layer for it. The technical investment is modest – the hard work is understanding the file formats and review workflows specific to each domain.
Electronic device design is one vertical. But manufacturing encompasses many others: mechanical engineering, industrial design, civil engineering, and architectural drafting each have their own file formats and their own review workflows still running on legacy processes.
For each of those domains, the recipe is essentially the same: identify the canonical file formats, build a diff renderer that makes changes visually intelligible, wire up a review-and-approve workflow, and position against the "endless meeting to review a design" status quo.
The more specific the vertical, the less competition – and the more credible the product, because it speaks the domain's language rather than forcing engineers to translate their work into generic collaboration abstractions.
