Just Say Hey × co-working spaces
The space that turns strangers into a thriving professional community keeps its members, fills its events and becomes impossible to leave. We build that layer, and we want to run it with your community team.
01 The problem
Community is the product co-working sells over a serviced office and a café, and in most spaces it lives entirely in one heroic community manager and a Slack that went quiet in March.
The gap between those first two numbers is operational, not philosophical: connection happens when someone engineers it. Great community managers do it through sheer personal effort. They know everyone, they make the introductions, they fill the room. Our whole thesis is what happens when that effort gets leverage.
What we believe
Community isn’t a Slack channel and a monthly pizza night.
Just Say Hey is an in-person community platform: the layer that makes a space know itself. Who's in, who's new, who does what, what's on this week, and who else wants to come.
02 The idea
Not another members' portal with a dead forum tab. One living community per space, under your brand, run by your team with our machinery underneath.
03 What it feels like
A new member signs up and the space already has faces: who sits where, who does what, which groups fit. Day one ends with three hellos instead of a wifi password.
"Anyone up for lunch?" is one tap, not a Slack message into the void. It quietly forms a table of members who are actually free at 12:30.
Ana needs a developer; Tomás just joined and is one. The platform suggests the intro and your community manager makes it, in thirty seconds, with context.
A designer runs a portfolio-review night, a founder hosts office hours. The events calendar stops being your team's chore and becomes the space's heartbeat.
Your team sees who hasn't connected with anyone or attended anything, so the check-in coffee happens in month three, not in the exit interview.
The space across town is cheaper per desk. But their accountant, their gym partner and their Friday demo audience are all here. That's the renewal conversation now.
04 The platform
All of this exists and runs now, built over the past year with real communities and hosts. Nothing here is a mock-up.
Poster-first event pages that share beautifully, free RSVPs or paid tickets with payouts to your own account, capacity, waitlists and recurring series.
A full-screen check-in tool for events: scan a QR or search a name. You know who actually came, and your public workshops run like clockwork.
Searchable profiles of what everyone does and needs. The freelancer finds the client, the founder finds the developer, inside your walls.
Suggested intros based on interests, industry and asks. Your community manager approves in seconds what used to take a memory palace.
Lunch, coffee, a walk between calls: one tap forms a small chat of members who are actually free, instead of a broadcast nobody answers.
Interest and industry groups that are feed and chat in one, with the ghost-town failure mode designed out, so they stay alive past the launch week.
Space updates surface on entry until read, then archive tidily: visible reach for the things that matter, without another all-members email.
Post-event feedback goes out automatically and comes back as exportable data. Every demo day tunes the next one.
05 For your team
One person cannot personally know 300 members, but one person with the room's map can act like they do. That's the job this does.
The economics
Your moat isn’t the fit-out. It’s the room’s relationships.
Desks, coffee and meeting rooms are commodities the building next door can undercut. A member whose clients, collaborators and lunch crew live inside your community has a switching cost no discount beats, and tells the story that fills your next tour.
06 Working together
We're proposing to build the co-working version of this platform alongside operators who actually run rooms, starting with yours.
Your community team shapes the space before members see it: groups, calendar, rituals, tone. You know your members; we bring the machinery.
White-labelled as your member community. Your guidelines and moderation standards, enforced by the platform and decided by you.
Minimal data, collected transparently, exportable to you, never sold. Members choose what the room sees: quiet by default, kind by design.
Whatever the pilot needs to fit your membership stack and workflows, we build as part of the partnership.
07 The pilot
A small, reversible experiment with success criteria we agree on before we start, not a contract with a pilot attached.
Calls with your community team: how the space runs today, which rituals work, where the effort burns out, what members ask for.
Map the pilot site into the platform: branding, groups, the quarter's calendar, roles for staff and a few member champions.
We run member onboarding alongside your team and carry the operational load. Your staff's cost is enthusiasm, not hours.
Metrics agreed up front: activation, event attendance, introductions made, and member-reported sense of community, next to your own renewal numbers.
Scale across locations, adjust, or stop. Either way the data is yours and exports cleanly, and no member's network gets held hostage by a vendor decision.
08 Fitting in
You already run a stack for desks, doors and billing. We deliberately don't touch any of it. We make the people layer, and meet the rest.
09 Who you'd work with

Grant Fullston, founder of Just Say Hey. Melbourne, Australia.
I’ve hosted around 300 in-person events and built and ran a 2,000-person community before writing a line of this platform. Before that I was a senior AI engineer. Everything in this proposal was built alongside real community hosts and shaped by their feedback.
I started Just Say Hey because finding your people shouldn’t come down to luck, and a co-working space is one of the few places adults still get to. If we work together, you work directly with me.
10 Start the conversation
Tell us a little about your space and we’ll come back within a day or two to find a time. There’s nothing to prepare. We mostly want to hear how community works in your rooms today.
