Sizzle® Synth Humans® engage your customers the way your best employee would — and capture what they share. Intent. Preference. Timing. Readiness to buy. The conversation is the intelligence. Every session compounds it. Generative AI creates the conversation. Agentic AI turns it into action — bookings, transactions, CRM updates — scoped to your systems, priced separately.
What is the most expensive conversation your business is not having right now?
For a restaurant, it is the reservation inquiry that came in at 10pm and went unanswered until the customer booked somewhere else. For a law firm, it is the intake conversation that never qualified the lead. For a retailer, it is the customer who had a question about your premium product and left without asking. For a hospital system, it is the training that new hires received inconsistently because the trainer had a bad day. The conversation is different for every business. The platform that makes it possible is the same.
If your business has a conversation worth having, a Synth Human can be built for it.
These are examples — not a complete list. The question is not whether your use case is here. It is whether you are having your most valuable conversations at scale.
Staff Training & Onboarding
Consistent, scalable training delivered the same way every session. New-hire onboarding, product knowledge, policy walkthroughs — adaptive to learner pace, with conversation logs reportable in the Sizzle® dashboard.
Customer Engagement & Service
Not a chatbot. A face, a voice, and a personality that represents your brand. Product questions, pricing comparisons, after-hours inquiries — answered from your approved content at 2am or 2pm.
Sales & Lead Qualification
Opens the sales conversation, qualifies intent against your approved criteria, and recommends the right product or service. Hands your team a warm prospect with full context instead of a cold name.
Recruitment & Interviewing
First-round interviews delivered consistently. Same questions, same evaluation framework, every candidate. Bias from interviewer fatigue eliminated by design.
Compliance Conversations
Policy walkthroughs, procedural training, and acknowledgment conversations delivered interactively — with a transcript for each session. Formal audit trails and certification scoped per regulatory framework.
Concierge & Guest Experience
Lobby kiosks, retail floors, event desks. A consistent first point of contact for visitor questions, drawing answers from your approved content. Returning-guest recognition and loyalty integration scoped as agentic.
Events & Experiential
A Synth Human that hosts, guides, and engages inside your event environment — physical or digital. Conferences, trade shows, product launches, brand activations, fan experiences.
Internal Help Desk & Operations
HR questions, IT policy, benefits navigation, internal procedures. Handles the repetitive internal inquiries that consume your team’s time — so your people focus on work that requires judgment.
Brand Ambassador & Spokesperson
A custom AI replica built from your footage — your face, your voice, your presence — deployed as your digital brand spokesperson across website, kiosk, digital signage, and app.
Product Expert & Demo
A product specialist who knows your entire catalog — every spec, every use case, every comparison — and demonstrates, explains, and recommends without fatigue or commission pressure.
Health & Wellness Navigation
Patient intake, preventive care guidance, benefits navigation, mental health support, senior companionship. Medically informed, boundary-aware, available 24/7.
Digital & Emerging Channels
AR experiences, gamified loyalty, OTT platform companions, smart building interfaces, kiosk deployments, digital signage. Wherever a screen exists and a conversation creates value, a Synth Human can live.
311 brains. 200 faces. 250+ already speaking.
Sizzle separates what a Synth Human® knows from who delivers it. 311+ engineered brains in the library — each one fully built: identity, domain knowledge, guardrails, voice, mood awareness, memory, TTS. 200+ cast faces — on-camera presence, voice tone, demographic fit. 250+ already paired and conversationally live. The result: 62,000+ possible castings, the world’s largest engineered Synth Human® library, deployable across 40+ industry verticals.
Pick the power dynamic. The library scales to all three.
The same Pantheon supports three deployment patterns — depending on whether you want us to cast, your team to cast, or your end customers to cast for themselves.
Curated Casting.
Tell us your brand, market, venue, and audience. We pair the right brain with the right face from the library and deliver a deployment-ready Synth Human® you can drop into production.
Brand Casting.
Your team browses the library and selects the persona that fits your brand voice. Lock it to your business. We tune voice, knowledge, and on-camera presence to your specifications.
Consumer-Choice Casting.
Put a curated set of Synth Humans® in front of your end customers and let them choose who they want to interact with. Demographics, comfort, cultural fit, brand affinity — every customer meets the guide that feels right to them.
Any face. Any brain. 62,000+ combinations.
The casting architecture isn’t theory — it’s production. Here’s what Model 03 looks like in deployment: one engineered Concierge brain delivered through five different cast faces, so your end customers meet the one they identify with. 311 brains times 200 faces equals more castings than your competitors can imagine. We curate the right combinations for your brand.
The conversations that matter most. Built for your business.
A closer look at the four highest-impact applications of a Synth Human® — with the math on what each one actually changes inside a business.
Training & Onboarding
The consistency problem in training is fundamental: the tenth person to receive the content never gets the same experience as the first. Trainer energy varies. Delivery varies. Questions change the flow. At scale, the inconsistency compounds into a measurable performance gap.
A Synth Human® delivers the same training at the same standard, every time. It adapts to the learner’s pace through real-time responsiveness — slowing down when confusion is detected, going deeper when engagement is high. Completion and comprehension are logged. The data is clean. The standard is maintained.
Customer Engagement
Every business has hours when customers have questions and nobody is there to answer them. Those moments — the 10pm inquiry, the Sunday afternoon question about your premium offering, the visitor who had one hesitation and left — represent real revenue that never happened.
Your Synth Human® is there for those moments. It knows your approved Knowledge Base — your products, your pricing, your policies, your brand voice — and answers with warmth, in-language, and in context. Traditional chatbots return text in a box. A Synth Human® appears as a person and holds a conversation the way your best employee would. The face is not a gimmick. It is what makes the conversation happen in the first place.
Sales & Lead Qualification
The difference between a lead and a qualified lead is a conversation. Most businesses collect contact forms — and hand cold information to a sales team that has to start from zero. Your Synth Human® opens the conversation, understands what the prospect actually needs, and recommends the right solution.
When the visitor chooses to share their contact info — to receive a quote, schedule a callback, redeem an offer, or unlock gated content — the Synth Human® captures it in context and hands your team a warm prospect instead of a cold name. Experience Pass attribution pays through when a captured lead converts.
Recruitment & Interviewing
First-round interviews are expensive in time and inconsistent in execution. Two interviewers in the same company ask different questions, create different impressions, and evaluate candidates on different implicit criteria. At scale — seasonal hiring, high-volume roles, multi-location expansion — the inconsistency becomes a liability.
Your Synth Human® conducts the structured first-round interview at scale: every candidate receives the same questions, the same experience, the same evaluation framework. Responses are logged and scored for your team to review. Bias from interviewer fatigue is eliminated by design.
Six capabilities. Built in. Plus what’s available.
Every tier ships with the capabilities below. Optional agentic-AI integrations, advanced attribution, and bespoke workflows are scoped after a discovery interview.
70+ Languages
Detects the language your customer or employee speaks and responds in it with full persona warmth. Language quality varies by pair — we walk you through performance in the languages that matter. Deployed across 100+ nations at the United Nations.
Real-Time Responsiveness
The persona reads engagement signals during the conversation and adapts accordingly. Confused? It simplifies. Engaged? It goes deeper. The interaction feels like a conversation, not a form. Built on proven video-AI infrastructure.
Memory — Where It Fits
Optional, not default. For subscription-style deployments where users sign in, the persona picks up where the last conversation ended. For anonymous web visitors, we recommend session memory only — no account barrier to ask a question.
Brand-Aligned Knowledge Base
When Sizzle® builds your custom Knowledge Base (Perform tier and above), the persona operates inside your approved content — your products, your voice, your policies. Tier 1 Activate uses Sizzle’s shared vertical knowledge.
Platform Integrations
Your Synth Human® can connect to common business platforms — booking systems, CRMs, POS, loyalty, scheduling — through Sizzle®’s agentic AI layer. Scoped and priced per integration after discovery. Per-action fees apply.
Conversation Analytics
Sessions, engagement time, conversation topics, language breakdown, and Experience Pass redemptions — all reported in a real-time dashboard. Off-site conversions and funnel attribution beyond the session are an add-on.
What does it cost vs. what does it make?
The right question is not what a Synth Human® costs. It is what the conversations you are not having are costing you — in lost leads, missed upsells, inconsistent training, and customers who went to a competitor who was faster. Tier 1 fits businesses doing $20K+/month, Tier 2 fits $50K+/month, Tier 3 fits $150K+/month.
Consider a Tier 2 client doing $80,000 per month in revenue. Most businesses at this scale are leaking revenue in six specific places at once: after-hours inquiries that nobody answers, leads that go cold waiting for a callback, carts abandoned at the form, premium offerings never surfaced, routine first-tier questions that consume staff hours, and new-hire ramp time stretched by inconsistent training.
A Sizzle® Synth Human® addresses all six — every hour, in every language, for every visitor — from the day it goes live.
The six line items to the right are modeled against documented third-party benchmarks. Applied against an $80K/mo revenue profile and ~3,000 monthly digital touchpoints, they compound to $12,600/mo in recovered revenue and deflected cost. Before a single Experience Pass commission is counted.
The platform pays for itself in the first month. Every month after that, it compounds: the Knowledge Base deepens, attribution sharpens, and the Synth Human® learns your customers.
Illustrative ROI — Perform Tier Client
Every deployment is custom.
No two businesses have the same conversations, the same systems, or the same revenue model — so no two Sizzle® deployments are priced from the same template. Every engagement is scoped to your business after a discovery interview, and quoted in writing before any work begins. The shapes the engagement can take are below.
Pick from the Pantheon.
License an existing Synth Human® from a library of 311 brains and 200 faces — 250+ already cast and conversationally live. The fastest path — days, not months. Strong fit when the persona is the function, not your competitive edge.
Make one yours.
Take a category specialist — hotel concierge, QSR order taker, dental practice host, beauty advisor — and lock it to your brand. Your name, your voice, your knowledge, your category exclusivity. Your competitor cannot have it.
Build a new one.
We design, engineer, and build a Synth Human® from scratch to your brand exactly. Face, voice, knowledge base, behavior. Hollywood-caliber craft. Yours in perpetuity.
What you can expect in the conversation
Discovery first. A working call to understand your business, your traffic, your systems, and the conversations you most need to have. No commitment required to take the call.
Written scope. Sizzle® returns a written scope with the persona, knowledge base, deployment surfaces, agentic integrations, timeline, and a fixed quote before any work begins. No meter that runs away from you.
200-minute QA Allowance at launch. Every new engagement includes a structured QA period where you stress-test the deployment before it goes consumer-facing. Sizzle® makes adjustments identified during QA before public launch.
The Experience Pass — Sizzle® earns only when you earn.
When your Synth Human® drives a sale, you see it in your revenue. The Experience Pass puts Sizzle® inside your transaction flow — attribution is automatic, settlement is clean, and we only earn when you earn. Commission terms are negotiated per deployment based on the kind of revenue your persona is driving — retail, hospitality, events, games, lead handoff, or internal training (which carries no commission).
Agentic AI: when the persona acts on your systems.
Every Synth Human® ships with a full generative AI layer — the persona, the conversation, the voice, the Knowledge Base, the dashboard. What converts a conversation into a completed action on your stack is agentic AI: the layer that lets your Synth Human® book, order, write, redeem, and hand off — inside the systems you already run.
Booking & Scheduling
Reservations, appointments, tee times, showings, test drives, service windows. The persona confirms availability in your booking system, holds the slot, and writes the record — inside the conversation, no human handoff.
CRM Write-Back
Every qualifying conversation writes to your CRM — lead captured, contact enriched, opportunity staged, activity logged. Your sales team sees the Synth Human® as another rep with clean attribution.
Transactional Actions
Order placement, upgrade capture, add-on attach, payment handoff through your POS or commerce stack. The conversation ends with a completed transaction, not a promise to follow up.
Loyalty, Promo & Redemption
Sizzle-issued promo codes, points look-ups, tier-based offers, redemption at checkout. The persona knows who the member is, what they’ve earned, and what they’re eligible for — then transacts it.
HRIS / ATS Handoff
Candidate pre-screen, application intake, interview scheduling, status updates. For internal deployments, the persona operates across your HRIS or ATS so HR sees a complete record by the time a human is needed.
Calendar & Lead Handoff
Direct-to-calendar booking with the right rep, verified lead packets delivered to the right inbox, SMS confirmations, follow-up reminders. The persona closes the loop so nothing sits in a queue.
Deploy anywhere your customers already are.
Your Synth Human® is not confined to a web embed. Sizzle® deploys personas into physical kiosks at airports, malls, hotels, QSRs, and dealerships — into your existing backend systems so they can quote, book, and transact — and into your internal training environments so your staff learn the way your customers do. Same persona. Different surfaces. Each one scoped and built by Sizzle.
Kiosks at scale.

- Centralized dashboard across all deployments

Backend integrations.

- POS & booking system handoff
- Loyalty & ecommerce platform connectors
- ATS / HRIS for recruiting & training
