HubSpot agencies in Europe

6 agencies in the index build on HubSpot and serve buyers in Europe. Ranked by the evidence on record, the first three are Belkins (Dover, US, from $5,000 a month), SalesCaptain (London, UK, from $3,500 a month) and FullFunnel (Boston, US, from $5,000 a month). Every touch and meeting is logged where the sales team already works; ask whether sequences run from HubSpot or from a separate sending tool synced to 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 6 publish a monthly minimum, from $2,500 to $5,000, with a median of $5,000. None of them advertise pay-per-meeting or pay-per-lead pricing. The services most often offered here are cold email, GTM engineering 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 HubSpot agency cost?
5 of the 6 publish a monthly minimum, from $2,500 to $5,000, with a median of $5,000. 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, 0 agencies offer pay-per-meeting pricing and 0 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?
5 of the 6 build on Clay and 6 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.
