Partner spotlight: WarmUP

Most lead-gen agencies hand back a list and a handful of replies, then leave you guessing how the pipeline actually got built. WarmUP works the other way around. It treats outbound as engineering: it builds the data pipelines, enrichment, and automation that produce the meetings, and stands the whole system up in days, not quarters.

WarmUP is a US-based, AI-native GTM agency in the OutboundSync directory: a team that designs and runs multi-channel outbound across email, social, and SMS for B2B technology companies. They run the program on the platforms OutboundSync supports, and use OutboundSync to land that activity in the CRM.

Who’s behind it: Mike Hurley

WarmUP was founded by Mike Hurley, the company’s CEO. He runs the agency on a single conviction: outbound should be built and operated as engineered infrastructure, not sold as a list and a sending service — which is why WarmUP ships a running system rather than a batch of leads.

Why WarmUP builds the engine, not just the list

Most outbound comes down to a list and a sending tool. WarmUP works a layer up: it builds the full outbound system — multi-channel campaigns, data enrichment pipelines, and automation workflows — so the motion runs as infrastructure rather than a one-off send. The agency describes itself as AI-native, building the data and automation layer on Clay and a stack of 15+ integrated tools.

That framing changes what a client walks away with. Instead of a batch of replies and no idea how they came in, WarmUP hands over a running engine — sourcing, enrichment, scoring, and routing wired into the CRM — and reports standing it up in about 48 hours.

What WarmUP actually builds

WarmUP runs the full outbound cycle and the system underneath it. Its services span multi-channel outbound across email, social, and SMS, data and list building with verification, data enrichment pipelines, automation infrastructure, lead intelligence and scoring, CRM integration, and GTM strategy — typically opening with a 90-day plan.

The stack goes deep on Clay for the data layer and runs the rest on tools like Smartlead, Instantly, HeyReach, Apollo, Make.com, Twilio, HubSpot, and Salesforce — 15+ integrations in all. The client roster runs past 50 B2B companies, among them HG Insights, Demandwell, DeveloperTown, Sonicu, and Kizen.

Who WarmUP is for

WarmUP fits B2B technology teams that want a built outbound engine instead of a one-off batch of leads. It is a strong match for companies that want that system stood up for them — fast, given the reported 48-hour setup — and kept running after launch. The flexible model means a team can take the fully managed build or work alongside WarmUP on it.

The fit with OutboundSync

WarmUP already runs on the platforms OutboundSync supports, and HubSpot and Salesforce sit in its core stack. They build and run the engine — sourcing, data, sequences, and follow-up across email and social — 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 system built and run as infrastructure — not a one-off campaign — WarmUP is a team to know.
