Clay agencies in Europe

13 agencies in the index build on Clay and serve buyers in Europe. Ranked by the evidence on record, the first three are SalesCaptain (London, UK, from $3,500 a month), FullFunnel (Boston, US, from $5,000 a month) and Growth Alliance (Prague, CZ, from $2,500 a month). Clay agencies build signal-based lists and workflows the client can keep, and Clay runs a partner program that lists certified agencies by tier. Europe is many markets at once, so outreach in the buyer's own language and attention to national rules matter more than volume. 6 of the 13 publish a monthly minimum, from $2,500 to $10,000, with a median of $4,250. 1 offers pay-per-meeting pricing and 1 offers pay-per-lead; the rest work on a retainer or do not say. The services most often offered here are GTM engineering, cold email and intent data. 4 have a Clutch or G2 rating on file with the date it was read. Ask whether the workspace and its data stay with you when the engagement ends.

Questions

How much does a Clay agency cost?
6 of the 13 publish a monthly minimum, from $2,500 to $10,000, with a median of $4,250. Setup fees and minimum terms vary, so ask for both before comparing monthly prices.
Retainer or pay-per-meeting?
A retainer buys an agreed scope each month and suits a defined ICP with at least three months of runway. Pay-per-meeting moves the risk to the agency and suits offers with a short sales cycle. On this page, 1 agency offers pay-per-meeting pricing and 1 pay-per-lead.
How long until results?
New sending domains need two to three weeks of warm-up before volume goes out, and list building runs alongside it. Most agencies quote first meetings in weeks four to eight.
Does the stack matter?
13 of the 13 build on Clay and 5 work inside HubSpot. Ask who owns the sending domains, the data and the workflows when the engagement ends; some agencies hand them over and some keep them.
