What we do
Four things, done well.
We take on a small number of engagements at a time. If what you need isn't one of these, ask anyway. We usually know who to call.
Platform consulting
Deep technical work on your extension: architecture reviews, MV3 migrations, performance, security posture, platform API questions that nobody else has answers to.
2–6 weeksStore policies & review
Help preparing, submitting, and when necessary appealing reviews on the Chrome Web Store, Firefox Add-ons, and Edge Add-ons. We've been on both sides of the process.
Ad-hoc or retainerStandards advocacy
Represent your extension's interests in the WebExtensions Working Group. Draft proposals, navigate cross-browser politics, turn product needs into platform features.
RetainerDiligence & audits
Acquirer-side and investor-side technical due diligence on extension businesses. Codebase assessment, platform risk, review-process exposure, maintainer health.
1–3 weeksOpen standards
We don't just build on the platform. We help shape it.
Simeon has worked directly on multiple major web browsers and is a founding member of the WebExtensions Community Group, the venue where browser engineers from all major browsers and extension developers debate and align on the future of cross-browser extensions.
When a platform gap is blocking your product, we can do more than work around it. We can take it to the group, create proposals, build consensus, and contribute changes directly to browser engines.
