Hermes vs Trellus in 2026: pricing, features, and real tradeoffs for AI voice agencies
By Alfredo Romero, CEO Hermes · Updated May 2026
Hermes and Trellus appear in the same searches because both involve AI and voice. But they are fundamentally different products serving different buyers. Trellus is an AI coaching tool for human sales reps. Hermes is an operating platform for agencies deploying autonomous AI voice agents for multiple client businesses. If you are an AI voice agency operator evaluating platforms, here is what you need to know.
What Trellus actually does
Trellus is a real-time AI assistant for sales reps on outbound calls. It listens to live calls and provides coaching prompts, objection responses, and talk-track suggestions as the conversation unfolds. It also provides auto-dialing, call analytics, and rep performance tracking. The target user is a B2B sales team (SaaS, financial services, staffing) that wants human reps to close more deals. Trellus does not deploy autonomous AI agents that handle calls end-to-end without a human. A rep is always on the line.
What Hermes actually does
Hermes is the operating layer for AI voice agencies. An AI voice agency signs up clients (dental practices, home service companies, real estate teams, insurance agencies) and deploys autonomous AI voice agents that handle all their inbound and outbound calls without a human in the loop. The agent books appointments, qualifies leads, follows up on estimates, and dispatches jobs. The agency manages everything through a white-labeled portal under their own brand. Clients never see the word Hermes. The agency charges $500 to $2,000 per month per client and runs 5 to 20+ clients from a single Hermes workspace.

Best for: Hermes
AI voice agency operators running 3 to 50+ client businesses who need multi-tenant workspaces, white-label portals, per-client billing visibility, and autonomous inbound/outbound agents. Also for solo agency owners who want to start with 1 to 3 clients on the Starter plan and scale. If your business model is "I deploy AI voice agents for other businesses and charge a monthly retainer," Hermes is built for you.
Best for: Trellus
B2B sales teams with human reps making outbound calls who want real-time AI coaching, auto-dialers, and rep performance analytics. If your use case is improving how your own salespeople perform on the phone, Trellus or similar tools (Gong, Chorus, Salesloft AI) are the right product category. There is no overlap with the agency platform problem Hermes solves.
Where Hermes fits if you are using Trellus
If you run an AI voice agency and use Trellus internally to help your own salespeople close new agency clients, you can run both. Trellus improves your internal sales process. Hermes is the infrastructure for the product you are selling. They operate at different layers of your business and do not interfere with each other. For the client-facing autonomous voice agent infrastructure, Hermes has no direct competitor in the Trellus product family.

FAQ
What is Trellus and how is it different from Hermes?
Trellus is an AI-powered sales tool designed to help human sales reps make better calls. It provides real-time coaching, auto-dialing, talk-track suggestions, and objection handling prompts during live sales calls. It is built for sales teams at individual companies who want to improve rep performance. Hermes is a different product category: it is an agency operating platform that deploys fully autonomous AI voice agents for multiple client businesses simultaneously. Where Trellus assists a human on a call, Hermes replaces the human entirely, handling inbound and outbound calls without any human in the loop. They solve different problems for different buyers.
Would an AI voice agency use Trellus?
Not as a client-facing tool. Trellus is designed for internal sales team use, not for deploying AI agents on behalf of multiple end-client businesses. An agency running 10 home service, dental, or real estate clients needs multi-tenant workspaces, white-label portals, per-client billing, and autonomous voice agents that handle calls without a human. Trellus does not provide any of these. Some agency owners might use Trellus internally to improve their own sales calls to prospective clients, but it is not competitive with Hermes for the agency product itself.
How does Hermes pricing compare to Trellus for an agency operator?
Trellus pricing is per-seat for sales reps, which is the wrong model entirely for an agency running autonomous voice agents for clients. Hermes is priced per-workspace (per client): $149 for 3 clients, $399 for 7, $699 for 20. The Hermes model aligns with how agencies generate revenue: one monthly fee covers all the infrastructure for a set of client businesses, and you charge clients a margin on top. With Trellus, you would be paying per sales rep seat and still have no infrastructure for deploying AI agents on client businesses.
What should I use if I want both sales AI coaching and client-facing AI voice agents?
Use both for their separate purposes. Trellus (or similar tools: Gong, Chorus, Salesloft) for improving how your team sells and closes new agency clients. Hermes for the actual voice agent infrastructure you deploy for those clients. These are complementary tools at different layers of your business. The decision to use Trellus has no bearing on your choice of agency infrastructure platform. If you are evaluating agency platforms, compare Hermes against Synthflow, Voicerr, or the DIY stack, not against Trellus.
Is Trellus relevant for home services, medical, or real estate AI voice deployments?
No. Trellus is a sales coaching tool for human reps making outbound sales calls, typically in B2B SaaS, financial services, or high-volume inside sales environments. It is not designed for industries like home services, dental, or real estate where the use case is an AI agent handling inbound appointment booking, emergency triage, or lead qualification for end consumers. Hermes is built for exactly those verticals: see the vertical pages for dental, HVAC, real estate, home services, and others. Trellus does not compete in that space.
