Direct peers

• CIENCE: CIENCE is a directly competing outsourced B2B lead generation and SDR agency offering outbound prospecting, appointment setting, and sales development across multiple verticals — Belkins has even been named as a 'Best CIENCE Alternative' by ZoomInfo, underscoring direct competition for the same buyer.
• MemoryBlue: MemoryBlue is a B2B outsourced sales development agency focused on outbound SDR services for technology companies, directly competing with Belkins' core appointment-setting and SDR-as-a-service offerings.
• Martal Group: Martal Group is an outsourced B2B sales development and lead generation agency serving SaaS and tech companies, with a similar omnichannel appointment-setting model that directly overlaps with Belkins' core services.
• SalesRoads: SalesRoads provides outsourced SDR, B2B appointment setting, and inside sales services, competing head-to-head with Belkins for mid-market and enterprise sales development engagements.
• Callbox: Callbox is a long-established B2B lead generation and appointment setting agency offering multichannel outbound services, comparable to Belkins in target market, delivery model, and vertical breadth.
• Intelemark: Intelemark is an outsourced B2B sales and lead generation agency specializing in appointment setting and outbound campaigns, closely aligned with Belkins' core service portfolio and enterprise client focus.
• LeadsRain: LeadsRain is a B2B lead generation and appointment setting agency offering cold calling, email outreach, and LinkedIn prospecting — a directly comparable service offering to Belkins' omnichannel model.

Broad incumbents

• Apollo.io: Apollo.io is a sales intelligence and engagement platform that also operates agency-adjacent services; as one of Belkins' key data partners, it represents a broader incumbent that could disintermediate pure-play agencies by enabling in-house execution.
• Salesloft: Salesloft is a leading sales engagement platform used by enterprise sales teams; it competes indirectly with Belkins by enabling customers to run sophisticated outbound programs in-house rather than outsourcing them.
• ZoomInfo: ZoomInfo is a dominant B2B intelligence platform whose buyer's guides rank Belkins among the top lead gen agencies; it is a broad incumbent in sales data and increasingly in workflow, making it both a partner-distribution channel and a long-term disintermediation risk.
