One brain. Every lead. Your voice.
The autonomous engagement engine that works your entire database 24/7, deciding the right next move for every lead and executing it inside the CRM you already run.
First, which best describes you?
Pick the one that fits before reading on. The entire page below retunes to your world, the examples, the workflow, even the compliance language.
Follow-up isn't a people problem. It's a memory and persistence problem.
Leads go cold because nobody has time.
Internet leads need touch after touch over months. Your agents are showing homes and writing offers. Consistent follow-up across a database of thousands is not a job humans can hold in their heads.
ISAs are expensive, hard to retain, inconsistent.
A good inside sales agent costs real salary, takes months to ramp, and walks out the door with all their context. The next hire starts from zero.
The AI tools you've tried feel robotic.
Cohort drips and scripted bots send the same message to every lead regardless of context, in a voice that is obviously not your team's. Leads can tell. So can you.
One brain. Full context. Fresh judgment, every time.
Most vendors stitch a chatbot for new leads onto a drip for cold leads onto a third tool for inbound replies. Substrait runs every decision through one brain.
Watch
Signups, inbound texts, favorites, return visits, silent leads. Signal-driven, not calendar-driven.
Decide
Reads the full record, then picks from the real playbook: text, note, escalation, or intentionally nothing. Restraint is underrated.
Compose in your voice
Written fresh against your voice profile and banned phrases. Buyers, sellers, investors, past clients, vendors etc.
Guard, then send
Eleven deterministic guardrails run in code before any send: Fair Housing, frequency caps, time zones, STOP detection. Human-paced replies feel typed.
What the brain actually does all day.
Agents open a lead already knowing everything
Budget, timeline, motivation, financing, and preferences are written onto the lead record. Agents open a lead and instantly know what the AI knows.
Every lead type gets a different conversation
A new signup, a qualifying lead, a half-profiled active, a prime lead, and a pending lead under contract each get a fundamentally different conversation. Automatically.
Your voice, your rules, no code
Voice profile, banned phrases, neighborhoods, lender list, playbook, texting hours. The engine is universal, the personality is yours.
The moment your agent steps in, the AI steps back
When an agent texts or calls a lead, Substrait backs off and supports from behind with notes and tasks. It never talks over your people.
Human-only moments go straight to your agent
Scheduling, offers, contracts, complaints, and opinion questions route to the assigned agent with full context. When the AI promises a human action, it creates the task.
Cold outreach only fires after your agent makes the call
The cold cadence only fires after an agent logs a call attempt. Volume is rate-limited by your real call capacity, and the AI reads as a continuation of the relationship.
A hot signal becomes a personal text in 60 seconds
Favorites, return visits, and listing-view streaks trigger context-specific outreach within 60 seconds. Most tools run on calendars. Substrait runs on signals.
Every touch learns one more thing about the lead
For partial profiles, the brain has one goal per touch: organically surface a single missing pillar, motivation, timeline, financing, area, or price. Discovery, not interrogation.
Why teams pick Substrait
Your voice, your CRM, your data.
Substrait connects to the CRM you already run, Sierra Interactive and Follow Up Boss today, with Lofty, kvCORE, and Boomtown on the roadmap. No migration. Every message reads like your team wrote it, because your voice profile is the spec, not an afterthought.
Built by operators, proven on their own money.
Built inside a producing Las Vegas team and running live on the founder's own database of 38,000+ leads. Every guardrail exists because a real lead, agent, or compliance concern demanded it. Not a demo built for a pitch deck, productized.
Eleven things every lead deserves. One engine does all eleven.
Three kinds of tools claim to work your leads: real estate chatbots, AI sales reps, and human ISA teams. Broken into the three things that actually matter, here is where each one stops and Substrait keeps going.
Competitor capabilities summarized conservatively from public materials as of June 2026. Several are good products. None are one brain making every decision inside your own CRM, in your own voice.
Running live, right now, on the founder's own pipeline.
Operational facts from Substrait's production deployment on a producing Las Vegas team, not projections.
We built Substrait because we were tired of watching paid leads die in our own CRM. Now one brain works our entire database every day, in our voice, and our agents walk into conversations already knowing the lead's budget, timeline, and motivation.

Test it before you even buy.
Start texting with Substrait right now and watch it work a real lead in real time, it qualifies, answers questions, and knows the exact moment to hand off. No setup, no commitment.
Shadow mode first. You approve the voice before anything sends.
Shadow
Substrait makes real decisions on your real leads but sends nothing. You review every draft for at least 24 hours, in your voice, before you trust it.
Supervised
Turn on sending for a segment you choose, new leads or the cold pipeline first. Watch conversations and escalations flow. Expand as confidence grows.
Live
Substrait runs your full database around the clock. Your team gets a live dashboard, and your agents simply get warmer handoffs.
Per-office configuration is data, not code. Onboarding takes hours, not weeks, and most teams know by the end of shadow mode.
Questions, answered.
Will my leads know they’re texting an AI?
Substrait writes like a sharp, courteous team member: short, specific, grounded in the lead’s actual history, and paced like a human typing. It never pretends to be a specific agent it isn’t, and it hands off to a real person the moment a conversation deserves one.
What CRMs do you support?
Sierra Interactive and Follow Up Boss today, with Lofty, kvCORE, and Boomtown on the roadmap. The decision engine is CRM-agnostic by design, so new adapters slot in without touching the brain, and switching CRMs later keeps your whole configuration.
What about Fair Housing, TCPA, and compliance?
Compliance is enforced in code, not requested in a prompt. Eleven deterministic guardrails run between every draft and every send: Fair Housing language screening, one AI-initiated message per lead per 24 hours, your configured texting hours, cross-channel deduplication, and STOP detection. A failing draft gets one rewrite attempt, then it is blocked. The whole engine is guarded by 1,400+ automated tests on every release.
Will it talk over my agents?
No. The moment a human teammate texts or calls a lead, Substrait yields automatically and shifts to support: logging notes, updating the record, and creating follow-up tasks. On cold pipeline, the AI does not even start until your agent has logged a call attempt.
What happens to leads who say "stop" or go quiet?
Opt-outs are honored instantly and permanently. Leads who ask for space get it, with a scheduled, respectful check-in later. The brain treats silence as information, and "do nothing today" is one of its valid decisions.
How is this different from the AI in my current platform?
Platform bots run cohort scripts to qualify leads for that platform’s ecosystem, in the vendor’s voice. Substrait is one independent brain that reads each lead’s full record, composes fresh in YOUR voice, takes a much wider set of actions including restraint, and writes its intelligence back into the CRM you already own.
Your cold pipeline is dark today. Turn the lights on.
