Questions

Can you publish it to the Chrome Web Store for us? +

Yes - building, testing, and getting through Web Store review and publishing is part of the work, not an afterthought.

How do we start without a big commitment? +

You start with one clearly defined milestone - often a technical audit, architecture, or a first working slice. You review real progress before funding the next phase. No large upfront payment.

Who actually does the work? +

Our founder reviews every project and handles suitable engagements directly. When a project needs extra capacity or a specific specialty, a vetted ZeroCut engineer is matched in based on technical fit, budget, timeline, and availability - you are always told who is doing the work, never left guessing.

Tell us what you need

A senior engineer reviews every submission and replies with how we would approach it.

No large upfront payment. You fund one milestone at a time. Prefer the full form?
