Your knowledge,
with a face and a voice.
Synth Humans® are photoreal characters who know what your organization knows and explain it the way your best person would: face to face, patiently, in 70+ languages, on the phones and screens your audience already uses. Generative AI creates the conversation. Agentic AI turns it into action.
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.
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.
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.
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.
First-round interviews delivered consistently. Same questions, same evaluation framework, every candidate. Bias from interviewer fatigue eliminated by design.
Policy walkthroughs, procedural training and acknowledgment conversations delivered interactively, with a transcript for each session. Formal audit trails and certification scoped per regulatory framework.
Lobby kiosks, retail floors, event desks and guests’ own phones. A consistent first point of contact for visitor questions, drawing answers from your approved content.
A Synth Human that hosts, guides and engages inside your event environment, physical or digital. Conferences, trade shows, product launches, brand activations, fan experiences.
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.
A custom AI replica built from your footage, with your face, your voice and your presence, deployed as your digital spokesperson across website, kiosk, digital signage and app.
A product specialist who knows your entire catalog, every spec, use case and comparison, and demonstrates, explains and recommends without fatigue or commission pressure.
Patient intake, preventive care guidance, benefits navigation, mental health support, senior companionship. Medically informed, boundary-aware, available 24/7.
AR experiences, gamified loyalty, OTT companions, smart building interfaces, kiosks and digital signage. Wherever a screen exists and a conversation creates value, a Synth Human can live.
538 brains. 200+ faces. 250+ already speaking.
Sizzle separates what a Synth Human® knows from who delivers it. Every brain is fully built: identity, domain knowledge, guardrails, voice, mood awareness, memory. Every face is cast for on-camera presence, voice tone and demographic fit. Pair them and you get more than 100,000 possible castings across 40+ industries.
Pick who does the casting. The library scales to all three.
Tell us your brand, market, venue and audience. We pair the right brain with the right face and deliver a Synth Human® ready for production.
Your team browses the library and selects the persona that fits your brand voice. We tune voice, knowledge and on-camera presence to your specifications and lock it to your business.
Put a curated set of Synth Humans® in front of your customers and let them choose who they talk to. Every customer meets the guide that feels right to them.
One Concierge brain. Five faces.
The same knowledge of your guests, your policies and your tone, embodied by whichever face fits your brand or your customer. Your competitor cannot have your face. You cannot have theirs.
The conversations that matter most. Built for your business.
Training & Onboarding
The tenth person to receive the training never gets the same experience as the first. Trainer energy varies. Delivery varies. At scale, that inconsistency becomes a measurable performance gap.
A Synth Human® delivers the same training at the same standard every time, slowing down when it detects confusion and going deeper when engagement is high. Completion and comprehension are logged.
Customer Engagement
The 10pm inquiry, the Sunday question about your premium offering, the visitor who had one hesitation and left: real revenue that never happened.
Your Synth Human® knows your products, pricing, policies and brand voice, and answers with warmth, in-language and in context. A chatbot returns text in a box. A Synth Human appears as a person, and that 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. Your Synth Human® opens it, understands what the prospect actually needs and recommends the right solution.
When the visitor chooses to share contact details for a quote, a callback or an offer, the Synth Human captures them in context and hands your team a warm prospect instead of a cold name.
Recruitment & Interviewing
Two interviewers in the same company ask different questions and judge candidates on different criteria. At volume, that inconsistency becomes a liability.
Your Synth Human® runs the structured first-round interview at scale: same questions, same experience, same framework for every candidate, with responses logged and scored for your team to review.
Six capabilities. Built in.
Detects the language your customer or employee speaks and responds in it with full persona warmth. Quality varies by language pair, and we walk you through the ones that matter to you.
Reads engagement during the conversation and adapts. Confused? It simplifies. Engaged? It goes deeper. It feels like a conversation, not a form.
Optional, not default. Signed-in users pick up where the last conversation ended. Anonymous visitors get session memory only, with no account barrier to ask a question.
With a custom knowledge base, the persona operates inside your approved content: your products, your voice, your policies.
Connects to booking systems, CRMs, POS, loyalty and scheduling through Sizzle’s agentic AI layer, scoped and priced per integration after discovery.
Sessions, engagement time, topics, language breakdown and Experience Pass redemptions, reported in a real-time dashboard.
What does it cost? What does it make?
The right question is what the conversations you are not having are costing you, in lost leads, missed upsells, inconsistent training and customers who went to a faster competitor.
Take a business doing $80,000 a month. Most are leaking revenue in six places at once. Modeled against documented third-party benchmarks, a Synth Human® recovers $12,600 a month in revenue and deflected cost, before a single Experience Pass commission is counted.
Illustrative model based on documented benchmarks: HBR lead-response research, Baymard abandonment studies, SHRM onboarding cost data, Forrester labor-deflection benchmarks. Your numbers are modeled in discovery against your actual traffic, conversion and labor data.
Every deployment is custom.
No two businesses have the same conversations, systems or revenue model, so every engagement is scoped after a discovery interview and quoted in writing before any work begins.
License an existing Synth Human® from 538 brains and 200+ faces, with 250+ already live. The fastest path: days, not months.
Take a category specialist and lock it to your brand: your name, your voice, your knowledge, your category exclusivity. Your competitor cannot have it.
We design, engineer and build a Synth Human® to your brand exactly. Face, voice, knowledge, behavior. Hollywood-caliber craft, yours in perpetuity.
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 commission terms are set per deployment. Internal training carries no commission.
The premium spectrum: one commerce layer, endless engagements on top.
AI-driven tiered membership where your Synth Human is the concierge. Rewards for actions, engagement and advocacy, not just purchases.
Sizzle Spin, branded slot machines, trivia tournaments, virtual lottery and instant-win moments, in your colors and voice.
No-purchase-necessary sweepstakes with full legal scaffolding. Contests, polls and quizzes that feed first-party data.
Virtual try-on for cosmetics, skincare and apparel. Recommendations that feel personal because the persona has been paying attention.
A travel, hospitality, sports and entertainment partner ecosystem your competitors cannot match.
Interactive video that transacts and dynamic QR codes that unlock, all attributed through your commerce layer.
A white-label loyalty marketplace inside your brand. Points redemption, member pricing, tiered access. Your inventory, your rules.
Third-party brands deploy offers and mini-games inside your property and pay for the visibility. An ad platform you own.
Once-in-a-lifetime experiences your persona can sell, from the biggest events in golf, racing and sport.
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 and the dashboard. Agentic AI is what lets it book, order, write, redeem and hand off inside the systems you already run.
Reservations, appointments, tee times, showings, test drives. The persona confirms availability, holds the slot and writes the record inside the conversation.
Lead captured, contact enriched, opportunity staged, activity logged. Your sales team sees the Synth Human as another rep with clean attribution.
Order placement, upgrades, add-ons and payment handoff through your POS or commerce stack. The conversation ends with a completed transaction.
Promo codes, points look-ups, tier-based offers and redemption at checkout. The persona knows who the member is and what they’re eligible for.
Candidate pre-screen, application intake, interview scheduling and status updates, so HR sees a complete record by the time a human is needed.
Direct-to-calendar booking with the right rep, verified lead packets to the right inbox, SMS confirmations and reminders. Nothing sits in a queue.
Deploy anywhere your customers already are.
Not confined to a web embed. Sizzle® deploys personas onto guests’ own phones, into kiosks at airports, malls, hotels, QSRs and dealerships, into your backend systems, and into your internal training. Same persona. Different surfaces.
