02 — Make it useful
Capture a voice note, a promised intro, or a tag like investor, client, or mentor while the meeting is still fresh.
03 — Find the thread
Search by event or city, then surface the people you meant to follow up with before the momentum fades.
Where your network opens up
Travel mode turns a city into a familiar place. When you arrive, Pintrail shows the contacts you have nearby—and gives you a reason to reconnect.

Privacy, without the fine print
The point is remembering context—not tracking people. Pintrail starts with city-level exchange pins, and any precise location is always your choice.
Every exchange can preserve the city and event context without putting a precise spot on the map.
Choose when a specific place improves the memory and when it should stay private.
Decide what a recipient sees before you share a card, link, or tap.
Questions, mapped out
No. Your card opens on the web from a QR code, NFC tap, or link, so recipients can view it without installing the app.
City-level context is the default. Saving or sharing a precise location is opt-in, and you choose what a card reveals.
Filter your map by event, city, tags, or time since follow-up. Pintrail keeps the memory of the meeting attached to the person.
