## What they do

Outbound Catalyst is a B2B GTM infrastructure and revenue engineering firm helping European and US-based SaaS companies build systematic, signal-driven go-to-market operations — not just run campaigns.

Most outbound fails because it's built on activity, not intelligence. High send volumes, generic sequences, SDRs cold-calling off static lists. The result is noise — and a pipeline that looks busy but converts poorly. We call this activity theater. Our work is the alternative.

We design and build the underlying systems that make outbound precise: ICP definitions grounded in real data, buying signal engines that monitor target accounts for meaningful triggers, and multi-tiered campaign architectures that match engagement intensity to deal potential. Tier 1 accounts get fully manual, creative outreach. Tier 2 gets structured semi-automation with a calling layer. Tier 3 runs fully automated. Every tier intentional, nothing wasted.

Our GTM Ops function owns all market mapping, account research, and list delivery — freeing sales reps to focus entirely on conversations, not prep work. Data flows through structured pipelines: enriched, scored, and routed before it ever reaches a human.

The companies we work with typically sit between €3M and €100M ARR — SaaS founders and revenue leaders who've outgrown scrappy outbound and need it rebuilt as infrastructure. Many are Flemish or Dutch companies expanding into new markets, or EU-based SaaS businesses targeting mid-market accounts in Western Europe and the US East Coast. They have a product that works and a real ICP — what they're missing is the operational backbone to scale pipeline with precision.

Engagements run as retainers or structured build-outs. We deliver ICP analysis, campaign architecture, signal monitoring, sequence strategy, tech stack configuration, and ongoing optimization — often connecting Clay, Lemlist, Smartlead, Apollo, and custom-built TypeScript pipelines into a unified revenue system.

The output isn't a spreadsheet of leads. It's a compounding GTM intelligence layer that gets sharper every cycle — because knowledge accumulates instead of resetting with each campaign.
