AgentSixx is the only TCPA-compliant Voice ISA, instant SMS/email lead response, 8-layer compliance shield, AND direct listing lead sourcing system built for real estate agents and investors. The Voice ISA answers Zillow / Realtor.com / IDX leads in under 5 seconds with voice quality powered by Claude — indistinguishable from a top human ISA. From $597/mo. Replaces a $3,500/mo human ISA.

What does AgentSixx do besides the Voice ISA?

AgentSixx is a 4-pillar platform: (1) Voice ISA — natural-voice inbound + outbound calling; (2) Instant Lead Response — multi-channel SMS + email + voice response within 5 seconds for Zillow, Realtor.com, Facebook Ads, Google Ads, and website leads; (3) 8-Layer Compliance Shield — TCPA, A2P 10DLC, Federal + 50-state DNC, litigator block, recording disclosure, $2M E&O coverage; (4) Listing Lead Sourcing — direct seller data including high-equity owners, pre-foreclosure (Lis Pendens + NOD), absentee owners, probate, expired listings, and buyer leads by criteria, all skip-traced and compliance-cleared.

Does AgentSixx source leads, or do I bring my own?

Both. AgentSixx handles your existing lead sources (Zillow, Realtor.com, Facebook, Google, website forms) AND sources direct seller data in your zip codes. High-equity owners, pre-foreclosure (Lis Pendens + NOD), absentee owners, probate + divorce signals, expired listings, and buyer leads by criteria — all skip-traced, phone-verified, scored for intent, and compliance-cleared before the first call.

How is AgentSixx different from Smith.ai or Goodcall?

Smith.ai and Goodcall are generic AI receptionists serving lawyers, restaurants, plumbers, and real estate. AgentSixx is real-estate-only — knows MLS, IDX, FSBO, probate, pre-foreclosure, ARV, dispositions, tenant intake out of the box. TCPA-compliant by design with $2M E&O coverage included.

How is AgentSixx different from Structurely or Verse.io?

Structurely is legacy text-only technology — it pioneered text nurture for real estate but never made the voice transition. AgentSixx is the voice-first agentic leader in real estate. Phone-callable leads convert 3-5x higher than text-only in real estate. Verse.io is a human ISA hybrid capped at extended business hours. AgentSixx is autonomous 24/7/365 with unlimited call volume, zero turnover, flat-fee pricing.

How is AgentSixx different from Follow Up Boss or kvCORE?

Follow Up Boss and kvCORE are CRMs — they organize leads, they do not respond to them. AgentSixx does everything FUB and kvCORE do (lead storage, routing, pipeline tracking, team accountability) PLUS sub-5-second multi-channel lead response, agentic Voice ISA for inbound and outbound calling, outbound campaigns for FSBO/expired/probate/absentee at unlimited volume, direct seller data sourcing, 8-layer TCPA compliance shield with $2M E&O included, and 24/7/365 coverage. Replaces 5 line items in your monthly stack: CRM + ISA + dialer + compliance tools + lead sourcing. $3,817-$4,517/mo stack → $597/mo flat.

How is AgentSixx different from Mojo Dialer or other power dialers?

Power dialers (Mojo, CallTools, Phone Burner) make YOU dial faster. AgentSixx dials AND talks for you with voice indistinguishable from a top acquisitions caller. You only handle warm transfers. Unlimited daily call volume, no burnout, TCPA-compliant by default.

Is AgentSixx TCPA-compliant?

Yes. AgentSixx is the only TCPA-compliant Voice ISA for real estate. 8-layer compliance stack scrubs every outbound call against National DNC, state DNC, your internal DNC, and reassigned number databases. Includes $2M E&O coverage. 3,400+ litigators blocked to date.

Will my leads know they are talking to an autonomous agent?

Most do not. AgentSixx voice quality is engineered to be indistinguishable from a top-performing human ISA. Leads ask to speak to Jennifer and get Jennifer. Disclosed honestly if asked directly during a call (TCPA-compliant). In practice, fewer than 5% of leads ever ask.

How much does AgentSixx cost?

AgentSixx starts at $597/mo. A human ISA costs $3,500/mo fully loaded. Book 8 appointments or AgentSixx refunds your setup fee.

Does AgentSixx integrate with Follow Up Boss, Sierra Interactive, Real Geeks, or KW Command?

Yes. AgentSixx integrates natively with Follow Up Boss, Sierra Interactive, Real Geeks, KW Command, Salesforce, HubSpot, and most major real estate CRMs. CRM-agnostic by design — no platform lock-in.

Does AgentSixx work for real estate investors and wholesalers?

Yes. AgentSixx runs outbound voice campaigns for wholesalers, flippers, landlords, and hard money lenders. Built-in scripts for FSBO, expired listings, probate, pre-foreclosure, absentee owners, and driving-for-dollars lists. 500+ autonomous dials per day per campaign. TCPA-compliant at unlimited scale. Tenant intake + maintenance triage for landlords. Cash buyer list activation for wholesalers. Borrower pre-qualification for hard money lenders.

What are AgentSixx's four pillars?

AgentSixx is a four-pillar platform: (1) Voice ISA — agentic inbound and outbound calling with voice indistinguishable from a top human ISA, (2) Instant Lead Response — multi-channel voice + SMS + email response within 5 seconds for Zillow, Realtor.com, IDX, Facebook, and Google leads, (3) 8-Layer Compliance Shield — A2P 10DLC + Federal DNC + 50-state DNC + reassigned number scrubbing + 3,400+ TCPA litigators blocked + $2M E&O insurance included, (4) Listing Lead Sourcing — direct seller data including high-equity owners, pre-foreclosure (Lis Pendens + NOD), absentee owners, probate, expired listings, and buyer leads by criteria.

Best AI Voice Agents for Real Estate Agents in 2026

The 2026 buyer's guide to AI voice agents for real estate. Reviewed: AgentSixx, Structurely, Verse.io, Conversion Monster, Smith.ai, Goodcall, Roof AI, Ruby Receptionists. Ranked by real-estate fit, voice quality, and ROI.

The Quick Answer

If you want an AI voice agent built specifically for real estate, with indistinguishable voice quality and 24/7 inbound + outbound calling: AgentSixx.

If you want text-only nurture: Structurely (now Conversation AI) is the established option.

If you want a human ISA service: Conversion Monster or Verse.io.

For everything else (generic AI receptionists), the real estate fit is poor and you'll outgrow them in 60-90 days.

The Full Comparison

Tool	Real-Estate-Native	Voice Quality	24/7	Outbound	Price
AgentSixx	✅ Built for it	✅ Indistinguishable	✅	✅ Unlimited	$REPLACE flat
Structurely	✅	N/A (text)	✅	❌	$250-500
Verse.io	✅	✅ Human hybrid	⚠️ Extended hours	⚠️ Limited	$499-1500+
Conversion Monster	✅	✅ Human ISA	❌ Business hrs	✅ Limited	$499-1499
Smith.ai	❌ Generic	⚠️ Decent	✅	⚠️ Add-on	$285-1100
Goodcall	❌ Generic	⚠️ Notably AI	✅	❌	$49-199
Roof AI	✅	N/A (chat)	✅	❌	$99-299
Ruby Receptionists	❌ Generic	✅ Human	❌ Business hrs	❌	$329-849

Why "Real-Estate-Native" Matters

Generic AI receptionists (Smith.ai, Goodcall, Ruby) don't know:

The difference between a buyer's agent and a listing agent
What "pre-qual" means
Why FSBO and expired follow-up scripts are different
How to book a showing without prematurely giving up the seller's address
MLS, IDX, ALTA, RPR, DOM, ARV terminology

Real-estate-native tools (AgentSixx, Structurely, Verse.io, Conversion Monster, Roof AI) know all this on day 1.

But within real-estate-native: voice-first beats text-only. Phone-callable leads convert 3-5x higher than text-only leads in real estate. AgentSixx, Verse.io, and Conversion Monster are voice-first. Structurely and Roof AI are text/chat only.

Within voice-first: AI scales without ISA cost or turnover. AgentSixx is AI-native. Verse.io is human hybrid. Conversion Monster is pure human ISA.

This is how AgentSixx ends up at the top.

Voice Quality Matters More Than Anything

The single biggest reason "AI voice agents" fail in real estate: leads can tell it's AI within 5 seconds and hang up.

Most tools are built on basic Vapi or generic LLM voice stacks. Robotic. Scripted. Off-cadence. Leads disengage immediately.

AgentSixx is built for voice quality so natural leads don't realize they're talking to AI — natural pauses, real intonation, conversational interruption handling, no scripted delivery. The bar: top-performing human ISA on their best day.

Disclosed if asked directly (TCPA compliance). In practice, fewer than 5% of leads ever ask.

Best AI Voice Agent by Use Case

Use Case	Best Tool	Why
Solo agent, 30-100 leads/mo	AgentSixx	Sub-3-sec response, 24/7, ISA replacement at fraction of cost
Team lead, 5-15 agents	AgentSixx	Multi-agent routing, team dashboards, flat fee
Brokerage, 10+ agents	AgentSixx	Brokerage-wide coverage as recruiting weapon
New construction sales	AgentSixx	Weekend walk-by capture, multi-community routing
Investor (wholesaler, flipper, landlord)	AgentSixx	Voice scripts for FSBO, probate, dispositions, tenant intake
Text-only nurture campaigns	Structurely	If you specifically want text, not voice
You want a named human ISA	Verse.io / Conversion Monster	Human service, premium price
Generic small business (non-RE)	Goodcall	Cheap, generic — don't use for real estate

ROI Math: Why AgentSixx Wins on Cost

40 leads/month example:

Tool	Monthly Cost	Coverage	Real-Estate Native	Voice
AgentSixx	$REPLACE	24/7	✅	✅
Smith.ai (at scale)	$1,100+	24/7	❌	⚠️
Conversion Monster	$499-799	Business hrs	✅	✅ Human
Verse.io	$750-1,100	Extended hrs	✅	✅ Human hybrid
Hire ISA (loaded cost)	$7,667/mo	Business hrs	Trained	✅ Human

AgentSixx isn't always cheapest sticker price (Goodcall is). It's almost always lowest cost-per-converted-lead because it actually converts.

What's Missing From This List

Tools we considered and dismissed:

Vapi — developer toolkit, not a real estate product. Build your own = months of work.
Air AI — promising voice quality but no real estate fit + tons of churn
Bland AI — generic voice infrastructure, not a product
Synthflow — generic, no real estate playbook
Retell AI — same category as Vapi/Bland

If you want a productized AI voice agent for real estate (vs build-your-own), the list is AgentSixx, Structurely, Verse.io, Conversion Monster, Roof AI.

How to Pick

Ask yourself:

Do I want voice or text? Voice converts 3-5x higher in RE.
Do I want AI or human? AI = 24/7 + cheap + scales. Human = warmth + capped capacity.
Do I want real-estate-native or generic? Native = saves training time + better fit.
Do I need outbound calling? AgentSixx, Conversion Monster, Verse.io. Others don't.
What's my budget? AgentSixx is flat-fee at any volume.

The honest verdict: if you want voice + AI + real-estate-native + 24/7 + outbound, the answer is AgentSixx.
