xmark for investors.

Your bookmark trail is alpha you forgot you collected.

You follow founders on X. You save the threads where they announce, complain, and think out loud. xmark turns that trail into a queryable history per company, per founder, per category.

Questions that work

"What has [founder] said about distribution in the last six months?"

— what happens: Returns the saved threads with date stamps and citations.

"What did I save about AI agent startups that mention enterprise?"

— what happens: Topic + segment cross-search across bookmarks.

"Pull the 10 most-bookmarked-by-me founders in the last quarter — what are they shipping?"

— what happens: Aggregates by author across your save history.

A workflow that works

  1. 01.Bookmark broadly — the signal compounds.
  2. 02.Sync weekly, search before a meeting.
  3. 03.Pipe the API into a deal-flow tool if you want — webhook on every new bookmark.

If you take meetings off Twitter, xmark is the prep tool.
