Honest flag, same as when this came up earlier: I don&#39;t see a lead-gen services provider on G2 that clearly packages email plus LinkedIn outreach together with AI voice qualification as one bundled service, that specific combination is pretty cutting-edge and not yet how this category is organized. What&#39;s real and verifiable: Callbox and DemandWorks are established, well-rated lead-gen and appointment-setting agencies doing multi-channel outreach including LinkedIn. For the AI voice qualification piece specifically, Retell AI (4.8-rated) builds voice agents that call and qualify leads, but it&#39;s a tool you&#39;d pair with or layer onto an outreach service rather than something sold as one packaged offering today. So realistically, you&#39;re either finding an agency that&#39;s already quietly adopted AI voice internally (worth asking directly since G2 won&#39;t show it yet) or assembling the stack yourself. Are you looking for a full outsourced service, or would you rather build and own the stack in-house?
