circulate

A watershed for the stuff in your community

Stop buying what your neighbors already own.

Most of what you need to own once a year, somebody nearby already owns. Circulate is the layer that makes their stuff searchable, requestable, and trackable, without the awkwardness of strangers or the noise of a group chat.

  • Borrow what you need.
    Drills, ladders, mixers.

  • Lend what's asleep.
    Closets, garages, lofts.

  • Pass on what's grown out.
    Cribs, books, bikes.

Two circles overlap, items in motion between them. A watershed of shared stuff.

How it works

Three steps. No spreadsheet.

The current's already moving in your community. Circulate just makes it visible, and quicker to step into than borrowing the ladder ever was.

  1. 01

    Snap it.

    Photograph the things in your closet. AI fills in the title, the description, the category. You confirm.

    (Even that camp stove from 2019 counts.)

  2. 02

    Circle it.

    Pick the trusted groups it belongs to: friends, parents, building, tool library. Lend, rent, sell, or gift. Your terms, per circle.

    (Same drill: lend to friends, rent to the library.)

  3. 03

    Find it.

    One search across every circle you're in. Or post an Ask, and let the inventory you need come to you.

    (Send it out and see who comes back.)

The two-sided loop

Every neighbor is a holder and a needer.

Circulate is built around both halves. Inventory finds you when you're looking; demand finds you when you have something to share. The same trust layer carries both directions.

The holder

"I have stuff."

Your stand mixer
slept all winter.

List it once. Choose who can see it. The same drill is Lend in your friend group, Rent in the building's tool library, Sell in your gift-economy circle.

The needer

"I need stuff."

Three of your neighbors have a tile saw . None of them want to own one either.

Post an Ask. It goes out to your circles, dedupes across them, and comes back with offers. Sometimes from people you haven't met yet, but always inside your circles of trust.

The inventory already exists

It's all already there, in your closets and garages, asleep 364 days a year .

What if it were searchable? What if borrowing it felt as easy as buying a new one?

  • Tools

    DeWalt drill

    Used twice last spring.

  • Baby & kids

    Jogging stroller

    She's eight now.

  • Outdoor

    Tandem kayak

    Garage rafters since 2022.

  • Kitchen

    Stand mixer

    Twice a year, holiday cookies.

  • Tools

    16-ft extension ladder

    Always borrowed from someone.

  • Outdoor

    4-person tent

    Dry, footprint included.

  • Books

    Book club box

    Five novels, passed in turn.

  • Garden

    Lawn mower

    Sharing one with two units.

"We spent $800 on a crib she slept in for 14 months. The neighbor across the hall had a spare in a closet the entire time."

Why a new thing

The alternatives all break in specific ways.

  • Facebook Marketplace

    Search drops results. Alerts ghost you. Trust = none.

    Real keyword + meaning search. Shareable filters. A circle-vouched seller signal.

  • Buy Nothing groups

    Chronologically lossy. The post that matched is six months gone.

    Persistent inventory. Asks live until they're answered or expire.

  • Group chats

    "I know someone has a pressure washer. I forget who."

    One search across every circle you're in. Not buried in chat history.

  • Spreadsheets

    Tool libraries running on Google Sheets. 200 rows of dread.

    Member self-service. Condition photos. Maintenance memory. No more printouts.

Beyond friend groups

The same loop, scaled up.

Some communities outgrow Google Sheets. Tool libraries, parent co-ops, and makerspaces are running on the same primitives Circulate already speaks: items, members, loans, condition.

One library adds 100–500 items to the network. They anchor regional density. The flywheel runs in both directions.

"Our 3D printer booking is a shared Google Calendar. It's chaos. We need something between a spreadsheet and enterprise library software."

A makerspace coordinator who shall remain nameless

  • Tool libraries

    Shelves of drills, sanders, joiners. Members borrowing weekly. Replace the spreadsheet with member self-service, condition photos, maintenance schedules, and tipping when it's earned.

    100–500

    items per library

  • Parents & kids gear

    Tight-knit groups, expensive things with 14-month lifecycles. The crib, the stroller, the high chair, passed forward.

    $3.2k

    saved per family/yr

  • Makerspaces

    3D printers, kilns, pottery wheels, recording booths. Equipment that doesn't leave a building still needs scheduling, usage logs, maintenance memory.

    30+ hr

    saved per machine/yr
