Doers, not advisors

We treat every GTM problem as an engineering problem. Define the goal, scope the work, build the system, measure what it returns. Our deliverability are outbound campaigns, CRM data orchestration, and consulting - we hold ourselves accountable to results, not hours logged.

FAQs

Answers to the questions we hear most from B2B sales and growth leaders.

What is GTM Engineering?

GTM Engineering is the practice of building and operating the technical infrastructure behind go-to-market motions - data pipelines, outbound systems, CRM automation, and the workflows that connect all three. A GTM Engineer doesn't write strategy decks. They build the systems that execute strategy. At Vanderbuild, every engagement is GTM Engineering work: we own the infrastructure, run the campaigns, and measure what returns.

What does Vanderbuild actually deliver?

Three service lines, built to work together. Outbound: hypothesis-driven campaigns across cold email and LinkedIn, from ICP definition to qualified lead handoff. CRM data orchestration: enrichment, deduplication, automated routing and scoring inside HubSpot or Pipedrive. GTM consulting: strategy, positioning, and the systems map that connects both. Most clients start with one and expand as the infrastructure matures.

Why Clay - and what does being Clay-certified mean?

Clay is the operating layer that connects 130+ data sources, powers AI enrichment workflows, and feeds sequencers like Smartlead and HeyReach with clean, signal-based contact data. Our team holds four official Clay University certifications - AI Skills, Automated Outbound, Automated Inbound, and CRM Enrichment. That means we build natively inside Clay, not around it.

Should we hire a GTM agency or build in-house?

Building in-house is the right call if you have a dedicated RevOps or GTM team with capacity to own the toolstack, write copy, run tests, and iterate week over week. If that team doesn't exist yet - or is already stretched - an agency is faster and cheaper than hiring. Vanderbuild typically works with companies that want results before they have the headcount to produce them internally.

Which markets and industries do you work with?

B2B SaaS, software houses, agencies, and outsourcing companies - from SMB to enterprise. Geographies: CEE, DACH, Nordics, Benelux, Baltics, UK, and North America. If your buyer is a B2B decision-maker reachable by cold email or LinkedIn, the system works.
