Who it fits (our reading of its own pages; opinion)
From its own pages, Belkins serves B2B companies, with case studies in sectors such as finance, healthcare, SaaS, construction and environmental services. Its pages organize services by company size, listing enterprise, SMB and startup. They describe challenges such as revenue stagnation, slow deal closure, disconnected sales and marketing, and inconsistent lead quality. Clients engage through monthly retainer packages, with a small business package delivered through partnering agencies and a custom Enterprise plan. Its pages also say that clients attend the booked appointments and run the sales negotiations themselves.
What Belkins does, from its own pages
Its home page states that it delivers 100 to 400+ qualified appointments in a year through tailored omnichannel strategies, and its case study page says it has worked with companies from 50+ industries.
For appointment setting, its pages list cold email outreach, LinkedIn outreach and cold calling as outbound channels, with intent-based calling and messengers (WhatsApp and SMS) as follow-up add-ons. Its other listed services include outsourced SDRs, deliverability consulting, HubSpot CRM consulting, lead nurturing, sales enablement and account-based marketing. Its cold email page describes a process that starts with ICP validation and company analysis, moves to manual lead research, then a deliverability audit and tech setup, and then campaign launch with A/B tests on subject lines and copy.
Its account-based marketing page describes mapping 4 to 10 decision-makers per account and running 100+ touchpoints per account, with HubSpot-powered tracking.
These figures are the agency's own claims.
