Community spotlight: GTM Cafe

GTM Cafe calls itself go-to-market’s digital underground, and the name fits. It’s a Slack community where founders, operators, agency owners, and sellers trade the plays they’re actually running — the ones tested in the field, not the ones dressed up for a conference stage.

We build for go-to-market teams, and GTM Cafe is where a lot of the best ones actually hang out — founders, SDRs, agency owners, and the GTM engineers wiring it all together.

Who’s behind it: Kellen Casebeer

GTM Cafe was founded by Kellen Casebeer, who also runs The Deal Lab, a B2B outbound agency. He built his reputation on one idea: message-market-fit.

Message-market-fit is the discipline of testing a lot of messages against a lot of segments to find where you actually land, before pouring budget into scale. That same test-everything instinct runs through the community he built. GTM Cafe grew out of the Clay-focused office hours Kellen had been running as Clay Cafe, then widened into a room for the whole go-to-market craft.

The Deal Lab is the OutboundSync agency partner Kellen runs on the services side — we spotlighted their outbound practice separately — and GTM Cafe is where the same message-market-fit instinct gets tested in public every week.

Why he built it

Kellen didn’t set out to find another co-founder. He set out to find a room — a place to be part of, with people running the same plays he was. The usual options didn’t fit: he bounced off WhatsApp, and he was already living in Slack, so that’s where he built it. One rule held from day one and still does — this is not a place for self-promotion.

The name came from a line he picked up from Paul Scallis: a cafe is always open, and people come and go as they please. That’s the feel he was after — no pressure to perform, a door that stays unlocked, regulars who drift in and out on their own schedule.

Underneath it all is a Stoic philosophy quote that Kellen keeps coming back to — the one that pointed him toward the work he does now:

“If a man knows not to which port he sails, no wind is favorable.” — Seneca, Moral Letters to Lucilius (Letter 71, section 3)

What it’s like inside

The fastest way to understand GTM Cafe is to watch a single channel for a day. A thread dissecting why a cold-email sequence flopped sits right next to a World Cup bracket, and it’s the same people arguing in both.

In a given week, someone posts that they just got fired, and the replies pile up with encouragement and job leads. A few messages down, someone else celebrates their first real equity, and the room goes just as hard for the win. There are pointed takes on tooling: what Zoom actually wants with Common Room, whether HubSpot buying Warmly changes anything, which new platform is overhyped. Then, with no warning, a deep-dive on a founding document, a Breaking Bad tangent, and a wall of memes.

That mix is the whole point. Most professional communities pick a lane — all tactics, or all networking, or all vibes. GTM Cafe runs the serious craft and the human stuff in the same feed, because the people doing the work don’t separate the two.

Why it stands out

What makes GTM Cafe work is that nothing in it feels staged. It reads less like a professional network and more like a group chat between people who genuinely like the work and each other.

Some of that is the format. The closed-door Friday sessions mean the good stuff — the real plays, the numbers, what worked and what didn’t — gets shared in a room, not performed for an audience. The door policy helps too: new members get welcomed and folded in fast, and the international, all-hours crowd keeps the conversation going around the clock. Everything shared has been tested in the field, which is a quietly high bar most communities never clear.

“Scarcity drives value” is how Kellen frames the model. The invite request and the closed doors aren’t gatekeeping for its own sake — they keep the room worth walking into.

Most of what actually works in GTM doesn't get posted on LinkedIn. Competitors read LinkedIn... These are people doing the actual work that moves sales and marketing orgs forward from an AI-first lens, and not a bunch of people saying they replaced their SDR team with Claude Code so they can sell you a $200 Gumroad course.

What running it taught him

The hard part, Kellen says, is consistency — and watching who shows up when there’s nothing in it for them. Over time you learn to tell the difference between the people treating the room as a transaction and the ones who keep coming back, giving as much as they take. That reciprocity is what he’s built around.

Why we’re spotlighting it

We build OutboundSync for go-to-market teams — the operators running outbound across sending platforms who need that activity to land in the CRM cleanly. GTM Cafe is full of exactly those people, doing exactly that work, in the open.

That overlap is why we’re spotlighting it: the plays being debated in GTM Cafe are the ones our customers run every day. It’s a genuinely good room, and it earns the recommendation on its own terms.
