Clay agencies in Germany have multiplied since GTM engineering became a real job title. I went through Clay's partner directory and the Forge Experts list to find the teams worth a call.
Every agency here builds on Clay, but the work splits three ways. Some run outbound for you, some wire Clay into your CRM, and some build the system then hand it over.
Three certified Forge Experts take the top slots. They work from outside Germany, so I ranked them on Clay depth first. The seven boutiques after them are all based in Germany.
I scored them the same way as my breakdown of lead generation agencies in Sydney. Each card covers what they build, who they fit and what they charge.
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.
The work splits in two. Outbound covers volume campaigns, micro campaigns and signal-based plays, from market analysis through to booked meetings.
The second half is CRM data automation. They clean, enrich and segment your CRM, then connect inbound data to automated outbound.
In 2025 they launched 250+ outbound campaigns and built 50+ revenue engines, with DACH among their core markets. What I rate most is that every system runs inside your accounts. Pricing runs from monthly retainers to pay per warm lead.
B2B Boosted is one of the first Clay-certified partners in the UK. Clay sits at the heart of every bespoke outbound system they build.
I found their pitch on independence unusually concrete. Everything is set up under accounts you own, with no minimum commitment or termination clauses. Their stated goal is for you to outgrow them within three to six months.
You can trial them with a first Clay table built for free. After that, a 30-day pilot costs £1,999 and a three-month sprint runs £1,749 a month.
Every send gets human approval, which suits brand-sensitive German buyers. German is not among their listed languages, so plan for native copy review. My Clay review breaks down the platform pricing you inherit after handover.
Strongest Group is a Finnish GTM and RevOps partner with DACH listed among its core markets. Clay-powered outbound workflows built on real signals sit at the center of the offer.
All channels run as one motion. Cold calling, email, LinkedIn and retargeting feed a single pipeline. Calling is localized in several languages.
Pricing is pay per realized meeting, which I like because it shifts the risk away from you. The homepage claims 1,200+ meetings booked monthly and 250+ client companies across 15 countries.
RevOps infrastructure and sales enablement come alongside the outbound. Targeting leans on B2B intent data rather than static lists. German is not on their language list, so confirm who writes DACH copy.
Scalantec is a Berlin GTM engineering agency with Advanced Artisan status in Clay's partner directory. That is the highest tier among the Germany-based partners I found.
Done-for-you outbound runs across email, LinkedIn and cold calling. Clay handles the hyper-personalized prospecting, while copywriting and deliverability are included.
The RevOps side covers CRM clean-up, inbound lead qualification and full Clay integration with your stack. If you send through Salesforge, my Salesforge Clay integration guide shows how the tables connect.
Clay enablement is where I think they stand apart. They build, document and train your team with SOPs and templates. Minimum engagements start at one month.
andweekly is a Munich B2B marketing and sales agency and a HubSpot Diamond Partner. Clay sits at the center of its GTM engineering practice.
Clay acts as the intelligence layer on top of HubSpot. Their Clay enrichment runs waterfalls across 150+ providers and syncs both ways with the CRM.
Their ICP scoring is the detail I noticed most for the German market. It blends firmographic fit with live signals like hiring, new decision-makers and trade fair attendance.
Published impact stories include myneva and thyssenkrupp. Expect $5k+ a month and a three-month minimum, which suits mid-market budgets more than seed startups.
Arvana is a Berlin outreach agency with 30+ people and 200+ active B2B clients, according to its homepage. Its Clay profile describes it as a Clay market leader in DACH.
What separates Arvana, in my view, is pairing outbound with paid media. Clay identifies high-value accounts and tracks buying signals, then LinkedIn Ads, SEA and Meta add touchpoints.
Fully managed email and LinkedIn outbound runs alongside the ABM work. Research, deliverability and lead qualification are all handled in-house.
Best fit is B2B teams with clear product-market fit and ACVs from €20k to €250k+. Pricing starts at $5k+ a month with a one-month minimum.
simon&co is an official Clay Solutions Partner building GTM automation for B2B companies. Founder Simon Lechner is a Clay Community Lead who hosts regular events in Munich.
The stack goes beyond Clay into n8n, Claude, Gemini and Apify. Enrichment, scoring and routing plug into your CRM. Supported options include HubSpot, Salesforce, Pipedrive and Zoho.
The hellomed case study is the clearest proof point I found. Reply rates rose from under 1% to 15%, and the client closed EUR 126,000 in new ARR.
Across clients they report EUR 2.5m+ in generated pipeline and a record 65 meetings in five weeks. The minimum engagement is three months.
GTM Base is a Berlin RevOps and GTM engineering agency founded by Taimoor Tariq. He spent 12 years building RevOps teams across North America and Europe.
Clay is core to their enrichment, scoring, research and campaign orchestration. What I noticed is the infrastructure built around the tables, from CRM architecture to AI agents.
Agents handle prospect research, lead routing and follow-ups without reps touching them. Clay connects into your CRM, sequencer, Slack and call tools as one system.
Named clients include Groupon, Blinkist and Superb. Expect $5k+ a month, a three-month minimum and English as the listed working language.
AutomateDemand is a Düsseldorf agency that designs, builds and runs agentic GTM systems. The focus is growing through existing sellers rather than adding headcount.
Signal-based outreach routes hiring, tech-install, intent and product-usage signals to the right rep. AI agents then research and draft one-to-one messages at scale.
RevOps work covers lead scoring, routing, attribution and CRM hygiene. Enablement adds SOPs, templates and talk tracks so your team can repeat what works.
Ideal clients sit between seed and Series B, with ACVs from $20k to $200k+. I like that the first strategy call promises two concrete plays for your market and no pitch deck.
Targetory is a Bavarian Clay specialist building data-driven outbound for the German-speaking Mittelstand. Founder Rasmus pairs years of B2B selling with Clay University training.
I liked the core idea, a closed feedback loop in place of linear cold outreach. Every email reply, LinkedIn reaction and phone call feeds back into your data.
Over time lead costs drop as data quality rises. One client, Studicon, reports cost per qualified lead falling by more than 85%.
A partner network covers LinkedIn, AI architecture and CRM work for larger projects. Engagements start at one month, and the whole offer is presented in German.
Nearly every agency I reviewed builds the Clay layer and still needs a sending platform underneath. That sending layer is where Salesforge fits.
If your team can already build Clay tables, the Forge stack covers everything after the enrichment step.
