Ranked by the evidence on record, the first three are Martal Group (Toronto, CA), CIENCE (Denver, US, from $2,499 a month) and SalesRoads (Fort Lauderdale, US, from $6,950 a month). SDR outsourcing agencies provide dedicated sales development reps, managed by the agency and working as an extension of the client's team. Pricing usually follows headcount, so the questions are ramp time, rep turnover and whether reps can move onto the client's payroll. 11 of the 33 publish a monthly minimum, from $1,000 to $6,950, with a median of $5,000. 2 offer pay-per-meeting pricing and 0 offer pay-per-lead; the rest work on a retainer or do not say. Besides SDR outsourcing, the services most often offered here are cold calling, appointment setting and cold email. 2 build on Clay, 3 work inside HubSpot and 29 use their own or undisclosed tools. 21 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.
