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.
Outbound Catalyst. GTM infrastructure for B2B companies that are done guessing.
"Data-driven sales with AI is essential in today's challenging environment. With only 2 commercial profiles in our team of 7, doing it alone wasn't feasible. OC challenged me in ways I don't often experience and impressed me with their systematic, proven process - their clear methodology delivered immediate results with meetings booked in our first two weeks and over 1.2M in pipeline generated across Belgium and the Netherlands in 9 months."
Robovision raised 50M USD, hired 10 BDRs, and then realized they needed help onboarding & streamlining their operations. The result? Automated list building, hubspot workflow task creation and doubled meetings booked per event. More here: https://www.outboundcatalyst.com/case-study/robovision
Robaws is a bootstrapped Belgian B2B construction SaaS which added EURO 2M in net new ARR in 2 years since they started working with us for their pipeline growth. Always-on emails, phone follow-up & proactive cold calling is what does the job. More here: https://www.outboundcatalyst.com/case-study/scaling-outbound-success-for-robaws
