Our Partner & Provider Network

Transparent. Responsible. Best-in-class.

At Hunter Green, we believe clients deserve absolute clarity about how their systems work, how their data is handled, and which technologies power their voice concierge. Our partner network is intentionally selective: we only work with providers who meet the highest standards of security, privacy, performance, and environmental responsibility.

Below is a clear view of our technology partners, our subprocessors, and our commitments to privacy and sustainability — so you always know exactly how your concierge is built, delivered, and maintained.

  • ElevenLabs – Ultra-realistic voice synthesis, multilingual support, premium voice latency.

  • Telnyx – Enterprise-grade telephony, global SIP, and reliable call routing.

  • Retell AI – Real-time conversational voice agents and streaming pipelines.

  • SynthFlow / VAPI providers – For specific client use cases requiring rapid prototyping or specialized conversational patterns.

AI Models & Reasoning Engines

  • OpenAI / Anthropic / Google – Foundation models used for reasoning, qualification flows, and brand-aligned conversation structure.
    We carefully tune model selection based on your required privacy posture, region, and brand-alignment preferences.

Analytics & Performance Monitoring

  • Custom internal dashboards for qualification outcomes, call patterns, and conversation insights.

  • Third-party observability tools for uptime, latency, and system performance analysis.

Our Technology Partners

We work with a small ecosystem of leading voice-AI platforms and infrastructure providers. We choose each partner based on reliability, latency performance, multilingual capability, compliance posture, and ongoing innovation.

How we handle your data:

  • No client data is ever sold.

  • Data is only shared with subprocessors essential to delivering your concierge.

  • Conversations are handled through encrypted channels whenever possible.

  • We minimize data retention and store only what is strictly necessary for performance and troubleshooting.

  • We offer configurations to meet EU, US, and cross-border compliance requirements.

Subprocessors we use today:
We revise and publish updates as our provider network evolves.

  • Voice generation: ElevenLabs

  • Telephony & routing: Telnyx

  • Model inference: OpenAI, Anthropic, or other selected LLM providers

  • Hosting & compute: AWS / GCP based on deployment

Every subprocessor undergoes a thorough review for:

  • Security certifications

  • Data-handling policies

  • Regional hosting options

  • Retention/deletion policies

  • Environmental footprint

Data Privacy & Sub-processor Oversight

We treat privacy as a design requirement, not an afterthought. Every partner is chosen because their systems meet or exceed the standards expected by luxury brands and global operations teams.

Our Environmental Commitments

AI workloads consume energy—but we believe innovation should not come at the expense of planetary health. Our environmental posture is simple

We operate carbon-negative.

Your concierge contributes to a net-positive environmental impact.


Every year, we:

  • Measure real compute usage from our deployments

  • Estimate per-client and per-interaction carbon cost

  • Offset more than what we emit using high-quality, verifiable offsets

  • Participate in the SME Climate Commitment and exceed its targets

Our clients can see:

  • The carbon footprint of their concierge

  • How we calculated it

  • Where and how we offset it

  • Proof of carbon-negative operations

Working with the best. Showing you how everything works

We partner exclusively with leading providers in conversational AI, telephony, infrastructure, and compliance to ensure your concierge is fast, reliable, multilingual, and always on-brand. Every partner is chosen for excellence: human-level latency, 100+ language support, precise qualification reasoning, and voice quality that matches the standard of the luxury brands we serve. The result is a concierge that feels effortless, elegant, and commercially effective.

We also continually evaluate and integrate new advancements across low-latency voice pipelines, multimodal reasoning, on-prem and edge inference, sustainability-focused compute, and industry-specific systems like PMS, retail platforms, and booking engines. As the ecosystem evolves, we publish updates so you have a clear, up-to-date view of the partners powering your concierge.
