§ body
The problem
Decks and design files get shared as dead PDFs over email. The sender has no idea whether the recipient opened the file, skimmed it, or forwarded it. For a founder sending a pitch, or a design lead routing a review, that blindness is expensive.
The approach
Ambergate treats every shared document as a living link: one URL per recipient, email capture at the door for unknown viewers, per-slide analytics under the hood.
- Upload once, share many — each recipient gets a distinct, revocable link.
- Optional email gate, so you know who opened the file before they see it.
- Page-level dwell time: “they opened it” becomes “they read slides 3, 4, and 7 twice.”
- UI that matches the document, not the usual martech wrapper.
Outcome
Small product teams can ship focused tools fast when the problem is concrete. Ambergate didn’t need a new category — it needed a better default for a job thousands of people do every week.
