Intent data agencies in Europe
12 agencies in the index offer intent data and serve buyers in Europe. Ranked by the evidence on record, the first three are FullFunnel (Boston, US, from $5,000 a month), SalesCaptain (London, UK, from $3,500 a month) and Martal Group (Toronto, CA). Signals only help if someone acts on them quickly, so ask how fast a signal turns into a touch and which data providers sit behind it. Europe is many markets at once, so outreach in the buyer's own language and attention to national rules matter more than volume. 5 of the 12 publish a monthly minimum, from $2,500 to $10,000, with a median of $3,500. 0 offer pay-per-meeting pricing and 1 offers pay-per-lead; the rest work on a retainer or do not say. Besides intent data, the services most often offered here are cold email, GTM engineering and LinkedIn outreach. 9 build on Clay, 4 work inside HubSpot and 3 use their own or undisclosed tools. 6 have a Clutch or G2 rating on file with the date it was read. Before signing, ask for a sample sequence, the definition of a qualified meeting and who owns the domains and data afterward.

- Retainer or pay-per-meeting?

- 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?
- 9 of the 12 build on Clay and 4 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.
