Cold calling agencies for SaaS companies in Europe
8 agencies in the index offer cold calling for SaaS companies and serve buyers in Europe. Ranked by the evidence on record, the first three are Belkins (Dover, US, from $5,000 a month), Callbox (Encino, US) and Martal Group (Toronto, CA). Calling works best where buyers still answer the phone, such as manufacturing, logistics and the trades; check which countries the callers dial and from which time zone. SaaS buyers receive more cold outreach than almost any other segment, so a specific trigger such as a new hire, a funding round or a tool change matters more than volume. Europe is many markets at once, so outreach in the buyer's own language and attention to national rules matter more than volume. One of the 8 publishes a monthly minimum: Belkins at $5,000. None of them advertise pay-per-meeting or pay-per-lead pricing. Besides cold calling, the services most often offered here are appointment setting, cold email and SDR outsourcing. 0 build on Clay, 1 works inside HubSpot and 7 use their own or undisclosed tools. 4 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.
