Top 10 Best Clay Agencies in The Netherlands

Vanderbuild is a GTM engineering agency founded by Mateusz Sekta. The team finished as Clay Cup Vice Champions, ranked second globally and first in Europe.

Outbound is the first track, covering volume, micro and signal-based campaigns through to booked meetings. The second is CRM automation built on Clay enrichment, so records stay clean and segmented.

Benelux is one of the named markets on their Forge Expert profile. In 2025 they launched 250+ outbound campaigns and built 50+ revenue engines.

What I rate most is that every system runs inside your accounts. Since the team works in English and Polish, plan a native Dutch review. Pricing spans monthly retainers, project builds and pay per warm lead.

B2B Boosted is a UK team of certified Clay experts. Clay sits at the center of every outbound system they build.

Their pitch on independence is unusually concrete. Everything runs in accounts you own, with no minimum commitment or termination clauses. The stated goal is that you outgrow them within three to six months.

The homepage now offers one custom automation free, then a full system for a one-off fee. Their Forge profile also lists a 30-day done-for-you pilot at £1,999.

Every send gets human approval, which suits brand-careful Dutch buyers. Since Dutch is not among their languages, budget for a native copy check before launch. Because the tools sit in your accounts, factor current Clay pricing into the budget.

Strongest Group is a Finnish GTM and RevOps partner that lists the EU among its core markets. Clay-powered outbound built on real buying signals is a core part of the offer.

Channels run as one motion here. Cold calling, email, LinkedIn and retargeting all feed the same pipeline. Calling is localized in several languages.

Pricing is pay per realised meeting, which shifts more of the risk onto the agency. Their site claims 1,200+ meetings booked monthly and 250+ clients across 15 countries.

Ask early whether native Dutch calling is part of the plan. If per-meeting pricing appeals, weigh it against the AI SDR vs agency trade-off too.

Saleslift Studio holds Studio tier in Clay's partner directory. That is the highest tier among the Dutch-based agencies on this list.

The team covers strategy, workflows and live campaigns. They map the opportunity first, build the Clay processes second, then run and refine the pipeline.

The case studies lean enterprise. FedEx booked 243 meetings in six months through account-based sales across six countries. Eneco reports a 36% reply rate with 4.4% conversion to SQLs.

Clay's directory lists English, German and Dutch among their languages. There is no budget floor and the minimum term is three months.

Revenanas calls itself the leading Clay-certified agency in the Netherlands. It holds Advanced Artisan tier in Clay's directory.

The approach starts with data rather than campaigns. They map your TAM, clean and enrich the CRM, then layer buying signals on top.

After that you pick a path. Path A pipes real-time signals into your CRM and Slack. Path B embeds a fractional GTM engineer inside your team.

HelloPrint is the headline case, with 700+ qualified replies. Their ideal client sells deals above $15K with five or more reps. Clay's directory lists $5k+ a month with a three-month minimum.

Nebor is an Amsterdam GTM agency founded by two neighbours with 18 years of shared sales and marketing experience.

Three services are built to work as one system. Outbound automation sources and contacts buyers, while ABM and paid ads warm them up. RevOps then keeps the CRM honest.

I liked their rule that strategy comes before tooling. They prove one use case first, then expand from there.

Everything lives in your stack and gets documented before handover. They work in English and Dutch. Client Dymaxa credits them with over €3M in added pipeline.

Amsterdam-based closed:in is a Clay Solutions Partner building done-for-you outbound for B2B service companies. The promise is more sales calls within two to three weeks.

The Dutch detail stood out to me. For Gen-Zero they built a KVK-anchored prospecting engine that contacted 27,455 businesses and produced 142 opportunities.

Deliverability gets real attention, with Instantly Expert certification alongside the Clay badge. Another client opened the Netherlands, France, Poland and London through one rollout.

Clay's directory lists $5k+ a month with a three-month minimum. The free 10-provider Clay waterfall on their site is worth a look before any call.

DGTLMOTION is an Amsterdam growth partner building commercial engines for B2B SaaS and tech scale-ups.

The outbound machine runs in Clay. That covers waterfall enrichment and intent signals, plus AI-personalised outreach connected to your CRM.

Their benchmark claim is about one opportunity per 80 accounts, against a market norm closer to one in 300.

The team works embedded on dedicated days, with senior profiles only. The sweet spot is scale-ups and SMEs between €1M and €50M in revenue.

SPOTONVISION is an Amsterdam B2B marketing agency with 20 years of account-based marketing behind it.

As an official Clay partner, it now uses Clay to merge account intelligence with buying signals. Sales and marketing then act on those signals while accounts are still warm.

The case list includes 1:1 ABM for Salesforce and multi-country programmes for Cyclomedia. They also run buyer persona research, which suits teams unsure of their ICP.

Clay's directory shows a six-month minimum. That makes this a longer commitment than most agencies on the list.

GenFlows is a Dutch GTM agency led by Wouter Harink. It holds both the Clay Artisan and First 100 partner badges.

The model is fully operated. You hand over four things at kickoff: your ICP, sales scripts, CRM access and compliance rails.

From there they run the domains, lists and copy. They also handle sending and reply triage, with a report every week.

The headline case is $4.2M in commercial funding originated in 90 days for a fintech client. Clay's directory lists any budget with a one-month minimum.
