Sellfire provides AI-enabled human SDRs to B2B teams. Double the performance. Half the cost. None of the distraction. Trusted by leading brands like Stripe, FreshBooks, FieldPulse, and WooCommerce. Most "AI SDR" plays ask you to fire your SDRs and trust AI agents. Yet Anthropic and OpenAI both hire human SDRs. If the teams racing toward AGI still want humans on the phones, AI agents aren't ready to replace yours either. They're ready to amplify them. Most outsourced SDR shops sell low-cost labor and ask you for the playbook. Sellfire does neither — we build a scalable playbook and run outbound for you with certified human SDRs amplified by AI. Doubling isn't magic. It's math. We move four levers at once: 01 · METHODOLOGY — Logic-Based Selling, our proprietary playbook refined over hundreds of millions of cold calls. Scripted so any coachable, hard-working SDR delivers great and predictable results. 02 · TECHNOLOGY — Our own dialer, AI agents, multimodal sequences, native CRM integrations, and an API + MCP layer — all built in-house with updates shipping weekly. 03 · TARGETING — Multi-source data partnerships, agentic sourcing and enrichment tuned to your ICP, AI fit-scoring, intent signals, prioritized lead distribution, and continuous experiments that find what works before competitors do. 04 · EXECUTION — Hand-picked certified offshore SDRs, paired with a swarm of AI co-pilots driving outreach, real-time coaching, and follow-ups. Orchestrated by US-based Performance Advisors — battle-tested operators optimizing pipeline with your team. Net result: 2.6× performance vs. in-house, at 0.5× the fully-loaded cost, with a scalable funnel proven in under 90 days. We own the work. You own the close.
