Partner spotlight: The Deal Lab

Most outbound shops scale sends first and hope the message lands. The Deal Lab does the opposite: it treats outbound as an experiment to run before it’s a budget to spend. Find message-market-fit first, then pour volume into the narrative that already works.

The Deal Lab is an OutboundSync agency partner. If you run outbound through Clay, Smartlead, HubSpot, or Salesforce, they’re the kind of team that engineers the system behind it, and they use OutboundSync to land that activity in the CRM.

Who’s behind it: Kellen Casebeer

The Deal Lab was founded by Kellen Casebeer, the practitioner behind its message-first approach to outbound. He’s known in the go-to-market community as a hands-on outbound and Clay operator; a director of sales who has worked with him calls him “one of the best outbound practitioners in the space.” He also hosts GTM Cafe, a community of more than 1,650 operators trading what’s working in outbound right now.

His throughline is the conviction the agency is built on: the message is the variable that decides whether outbound works, so prove it in a pilot before you scale the spend. That belief, earned from running outbound systems rather than theorizing about them, is why The Deal Lab leads with experimentation instead of volume.

Why The Deal Lab finds message-market-fit before scaling volume

The name is the thesis. A lab runs the experiment before committing the budget, and that’s how The Deal Lab structures an engagement: validate the narrative, the ICP variants, and the channel in a short pilot, then scale only what earns replies. It’s the opposite of the spray-and-pray default, where teams buy a list, pick a tool, and find out the message was wrong after they’ve already paid for the volume.

That conviction is visible in the results. For one MarTech client, The Deal Lab lifted the email reply rate roughly 3x while cutting total sends by 83%, proof that a sharper message beats more sending. The point isn’t volume for its own sake; it’s that you earn the right to scale by proving the message first.

A CEO at a cold-calling agency put their standing in the category plainly on The Deal Lab’s site: “When it comes to Clay agencies and GTM systems, The Deal Lab are in a league of their own.”

What The Deal Lab builds

The work is a clinically run GTM practice, not a list-and-blast service. Engagements come in three shapes: a four-month Message-Market-Fit Pilot to validate the narrative and channel, a Done-For-You Outbound program that scales the proven motion, and bespoke GTM consulting across messaging, data, ops, and experimentation.

The stack is the one outbound operators recognize: Clay for targeting and enrichment, Smartlead for delivery, and Ocean.io for data, running into HubSpot and Salesforce as the CRM. Alongside the client work, the team runs GTM Cafe, a community of more than 1,650 members, which keeps them close to how outbound is changing.

The fit with OutboundSync

The Deal Lab already runs on the platforms OutboundSync supports, and uses OutboundSync to push that outbound activity into the CRM. They build the engine (messaging, data, sequences, calls), and OutboundSync makes the resulting activity visible on the right records in HubSpot or Salesforce so the rest of the revenue team can act on it.

If you want an outbound program that proves the message before it scales the spend, The Deal Lab is one to know.
