What Vendors See: The Live Map of Raised Hands

I’ve written about what wandering costs a truck and how the customer-finding toolkit evolved. This post is simpler: if you drive a truck and you’re wondering what Snack Signal actually puts in front of you, here it is — the shipped product, no vision-talk, in the order you’d meet it on a shift.

Before the shift: your followers accumulate

Residents who find your truck on Snack Signal can follow you. You don’t have to do anything to earn this except exist and serve them — every good window interaction quietly converts a one-time customer into someone who’ll be notified the next time you’re out. Think of it as the regulars list you always had, except it’s written down, and it works even for the family that only caught you once at the park.

Going live

When your shift starts, you go live. Two things happen:

  1. Your position broadcasts to residents nearby and to your followers, as a moving dot on their live map. This only happens while you’re live — end the shift and broadcasting stops instantly. You’re never trackable off-shift; the switch is entirely yours.
  2. Your followers get told. People who chose to hear from you get a notification that you’re out. As you work, residents near your position get a heads-up that a truck is close — the jingle’s job, done at neighborhood scale, before you’ve turned onto their street.

Practical note: your location comes from the phone on your dash. There’s also a set-my-location pin if you need to place yourself manually — useful when you’re parked somewhere GPS reads poorly.

The map of raised hands

This is the screen the whole product exists for. As residents raise the snack signal, pins appear on your map — each one a household that explicitly asked you to come, placed where they want you to stop. The queue sorts by distance and ETA, so the question you’re answering all shift changes from “where might buyers be?” to “which confirmed buyer first?”

What a pin is not: a like, a view, a maybe. Somebody stood in their yard, opened the app, and summoned you. In my experience explaining this to drivers, the reaction is some version of “wait, they come to me?” — which is exactly backwards from every marketing tool trucks have ever had, and exactly the point.

Accept and decline

Every signal gets an answer, and both answers are good for you:

  • Accept, and the resident knows you’re coming — they can watch your dot approach with an ETA. No more families giving up at minute nineteen while you’re two streets away and headed their direction.
  • Decline — end of shift, out of range, freezer’s empty — and they’re told immediately. This matters more than it sounds: the old way, a family that waited on you and got nothing learned to stop trying. A fast “not tonight” preserves the customer for next week. Silence is the only answer that costs you.

Cravings: demand from streets you don’t serve yet

When residents open the app and there’s no live truck near them, they can send a craving — what they wished was nearby. For you, that’s a bench of route intelligence no amount of driving could produce: unmet appetite, mapped, in neighborhoods you’ve never risked fuel on. It’s the answer to the question every route change gambles on — is anybody actually over there?

What the vendor side doesn’t do (yet)

Same honesty rule as everywhere on this blog. Today there are no payments through the app (your window, your rules — cash, reader, whatever you run), no published schedules, and no order-ahead. Those are on the roadmap, and when they ship you’ll read it here in the present tense. What exists today is the demand layer: go live, get found, see the raised hands, answer them.

The shift, before and after

Before: pick streets from memory, play the jingle, watch mirrors, hope. After: same truck, same jingle — plus a list of confirmed stops sorted by distance, an audience that’s told when you’re out, and a map of where demand lives that gets smarter every shift you run.

More sales, less gas. That’s the whole product. 🍦
