Know what your competitors changed — with the receipts.

Dossyr watches your competitors' pages and tells you what moved, and every claim quotes the page it came from, with a link to the exact version we fetched.

Join the waitlist

We're letting people in a few at a time. Three quick fields, and the rest is optional.

Name

Work email

Your company URL

Dossyr reads your own site first — it's what the comparison is built against.

Who are you up against? — optional

Skip it if you'd rather. If you do write something, you'll go higher up the list — it tells us whether we can actually help you.

Where did you hear about Dossyr? — optional

One email when there's a spot for you, and nothing else. No sequence, no list.

What changed, not what's there. We store every page we read, so a finding is a difference — not a description.
Checkable. If a quote can't be found in the page it came from, the finding is dropped rather than shown.
It runs without you. On a schedule, across your whole competitor set, so nobody has to remember to look.

Built for the person who owns the battlecard and finds out a competitor changed their pricing when a rep loses a deal over it.

What a finding looks like

Every claim is a quote from a page we fetched and stored.

This is a real finding from a live workspace, produced from a public careers page. Nothing here is illustrative — if the quote can't be located in the page we fetched, the finding is dropped rather than shown.

Anthropic is significantly expanding its compute infrastructure and supply chain capability, adding senior leadership for compute procurement.

What this is, plainly

It's a private beta, and the waitlist is real.: People come in a few at a time, so the ones already inside get looked after properly. If we can't help you yet, we'll say so rather than park you indefinitely.
The product is the memory, not the summary.: Anything can summarise a competitor's homepage today. Dossyr stores each page it fetches, so it can tell you what changed since last quarter — and show you both versions.
It will sometimes tell you nothing.: If a claim's quote can't be verified against the page it came from, we drop it. That means occasionally losing something true, which we prefer to showing you something you can't check.
