The Problem We Solve

Real estate runs on chaos. SIGNARA seals it.

Every real estate transaction has 8–12 professionals working in silos: agents email PDFs, lenders use one system, title uses another, buyers have no visibility. Deals fall apart not because of price — because of coordination failure.

SIGNARA is the single source of truth for every party, every document, every message, every deadline. One platform. Sealed.

01

Role-Based Visibility

Buyers see their lane. Agents see their deals. Admins see everything. RLS-enforced at the database level — not just the UI.

02

Deal Health Score

Every transaction gets a 0–100 health score updated in real time. CARI flags deals that need human attention before they miss a deadline.

03

Thread-Based Messaging

Five structured threads: General, Mortgage, Title, Inspection, Insurance. Every conversation in context, with visibility rules baked in.

04

Pipeline Command Center

See all your active deals in one view. Filter by phase, health, or closing date. Critical deals front and center, always.

05

Document Intelligence

Upload a purchase agreement and CARI extracts every field: address, price, contingencies, close date, party names. Zero manual entry.

06

Morning Briefings

Every agent and lender starts their day with a personalized CARI briefing: deals closing this week, at-risk transactions, overdue items. Conversational, not a spreadsheet.

“Contract to Sealed. Every party. One platform.”

SIGNARA — the all-party transaction intelligence platform for real estate.

Meet CARI.

Cooperative Operations & Relationship Agent. CARI isn't a chatbot — it's a deal intelligence layer that understands every party, every document, and every deadline in your pipeline. Before you ask, CARI already knows.


CARI · Live Conversation
What's the status on the Cumberland Ridge deal?
3847 Cumberland Ridge is in Closing phase. Health score: 85. Close date is May 24 — 19 days out. Buyer financing is clear, title commitment received. One open item: final walkthrough not yet scheduled. Want me to draft a message to the buyer's agent?
Yes, and flag anything closing this week
You have 27 transactions closing within 7 days. 3 are critical (health below 40): 127 Piedmont Park, 590 Means St, and 440 Juniper. Piedmont Park has 6 overdue deadlines — I'd start there. Drafting the Cumberland Ridge message now…
🧠

Deal Context Packet

Every CARI response is grounded in the full deal context: parties, timeline, documents, messages, and health score — built before your question even arrives.

📄

Document Extraction

Upload a PDF purchase agreement. CARI reads it and populates the entire transaction record: address, price, contingencies, parties, dates. One upload, zero data entry.

🎙️

Voice Interface

CARI can speak your morning briefing, answer questions hands-free while you're driving between showings — free on-device on iOS, free browser voice on web.

📊

Deal Health Score

A 0–100 score per transaction, updated continuously. Factors in overdue deadlines, missing documents, party engagement, days to close, and contingency status.

🌅

Morning Briefings

Personalized daily briefing before you wake up. SMS follow-ups 30 minutes later if not acknowledged.

The Technical Reality

Not another GPT wrapper.

CARI is architecturally different. The rules engine builds a complete deal context packet before any user message reaches the model. CARI knows your role, your deals, your parties, your open items. It doesn't hallucinate — it reads your database.

Claude Sonnet 4
Default model for all CARI conversations. Fast, accurate, context-aware. Handles 200K token deal contexts without breaking a sweat.
Per-Agent AI Tiers
Users can upgrade to Sonnet or Opus at the account level. Top producers get elite AI. Standard users get reliable Haiku. Billed accordingly.
Batch Processing
Nightly health score recalculations, post-close summaries, and digest emails use Anthropic's Batch API at 50% cost. Real-time stays premium. Async goes efficient.
Architecture

Built to scale. Not to pivot.

Every technology decision in SIGNARA was made for one reason: predictable performance at scale, with a cost model that doesn't blow up when you add 10,000 seats.

Full-Stack Framework
Next.js · TypeScript
Server Components render deals instantly at the edge. API Routes handle backend logic. SSE streams CARI responses in real time. TypeScript enforces correctness from database query to UI component — one language, one codebase, no translation layer.
React · App Router · SSR · API Routes · Type-safe end-to-end

★ Managed Database
Supabase
PostgreSQL with built-in Row-Level Security, real-time subscriptions, point-in-time recovery, and instant REST APIs — managed infrastructure with zero ops burden. SIGNARA's RLS policies are already written and battle-tested in the schema. Move from homelab to production with a single connection string.

AI Intelligence
CARI · Anthropic Claude
Claude running as a persistent spawn service co-located with the application. Real SSE streaming with session continuity — CARI remembers the full conversation. Active pipeline, deal health, and party context injected at session open. Future hook-in point for external AI APIs built in from day one.

Storage
AWS S3
Eleven nines of durability. Pre-signed URLs for direct browser-to-S3 upload — a 40 MB inspection PDF streams from the agent's phone straight into encrypted storage without touching the application server. Seven-year retention enforced automatically.
11-nines durable · Pre-signed direct upload · 7-year retention
Infrastructure
AWS · EC2 + CloudFront
EC2 hosts the persistent Node.js server — a hard requirement for CARI's spawn process and long-lived SSE connections that serverless platforms cannot support. CloudFront serves assets from 600+ edge locations. Full stack cost-modeled under $200/month for 10,000 seats.
EC2 · CloudFront · Multi-region · No serverless lock-in
Data Layer
postgres.js
Raw SQL over a persistent connection pool — no ORM overhead, no generated types to drift. Queries are exactly what hits the database. Tagged template literals prevent injection at the language level. Supabase-ready: swap the connection string and go.
Raw SQL · Connection pool · Injection-safe · Zero abstraction overhead

Signed JWT sessions with role-based access, demo persona support, and admin flags baked into every token. Passwords hashed with bcrypt. TOTP-ready. Demo mode lets prospects explore with real data and no credentials.

Communications & Integrations
Open by Design
Every external service is a swappable component. REST APIs throughout. Outbound data layer engineered to push transaction records directly into TC platforms, title-and-escrow systems, e-signature workflows, and back-office tools.

Document Intelligence

Every document. Understood.

SIGNARA handles the full lifecycle of real estate documentation — from initial purchase agreement through closing. CARI reads them. The platform organizes them. Your parties access exactly what they're allowed to see.

“Every document in its lane, every party seeing exactly what they should.”

SIGNARA document architecture — role-gated, AI-read, timeline-tracked.

All 12 Party Types

Everyone at the table.

Most platforms serve the agent. Or the lender. Or the title company. SIGNARA serves all of them simultaneously — with visibility rules that keep each party in their lane while giving the deal team what they need to close.

🏠
Buyer
The person closing on the property. Full access to their documents, messages, milestones, and closing timeline. Client portal shows their deal in plain English.
🤝
Co-Buyer
Same access as buyer. Separate account, same deal visibility. Married couples, investment partners, co-purchasers all covered.
🏡
Seller
Counter-party to the buyer. Sees their side of the deal: disclosure obligations, closing dates, proceeds estimate. Adverse party rules enforced.
👤
Co-Seller
Spouse, estate co-executor, investment partner on the sell side. Same adverse party protections as seller.
🏅
Buyer's Agent
SIGNARA's power user. Sees all threads, manages their pipeline, receives CARI briefings, advances deal stages, invites parties. The cockpit.
🏅
Listing Agent
Represents the seller. Access to general, inspection, and title threads. Cannot see buyer's mortgage details. Adverse party protections built in.
📋
Transaction Coordinator
The backbone of high-volume brokerage teams. Full pipeline visibility across all assigned deals. Checklist management, deadline tracking, document collection.
💼
Loan Officer
Access to the Mortgage thread. Sees borrower financials, rate lock, pre-approval, and CTC. Cannot see title or inspection details — clean separation.
⚙️
Loan Processor
Works inside the LO's lane. Same mortgage thread access. Often the one in SIGNARA all day, moving files from underwriting to CTC.
🏛️
Title Manager
Handles title commitment, search, endorsements. Title thread access. Sees parties, deadlines, and closing schedule. The hub of the title operation.
💰
Escrow Officer
Manages escrow account, holds earnest money, coordinates closing. Full closing phase visibility. Wire instructions handled through the Vault.
⚖️
Real Estate Attorney
Required in attorney states: GA, NC, SC, MA, NY, CT and more. Full deal access. SIGNARA auto-flags attorney-state requirements on transaction creation.
Competitive Landscape

Why SIGNARA wins.

Dotloop serves agents. SkySlope serves brokerages. Qualia serves title companies. None of them serve the whole deal. SIGNARA is the first platform built around the transaction itself — not the tool each silo already has.

Our Position

SIGNARA is the only all-party, AI-native transaction platform in the market. We're not competing with Dotloop for document storage — we're replacing the entire coordination layer across all 12 deal parties.

The TC Desk Killer

SIGNARA pushes data TO brokerage TC desks (LoneWolf, SkySlope) so transaction coordinators stop re-entering data. That's the signed check for large brokerages. No other platform does this.

Scale Target

Designed for 10,000 seats. Database sharding roadmap ready. Go backend handles 50K concurrent connections on $20 hardware. Cost per seat drops as volume scales. Priced to win enterprise.

“The platforms that serve one party will always lose to the platform that serves the deal.”

SIGNARA strategic thesis — the transaction as the unit of value.

Do you feel like you need
a second phone?

One for clients. One for your actual life. Because the moment you hand your personal number to a buyer — it's theirs. Forever.

Professionals run their entire business from the device that is always in their hand.

1:00 AM. Client texting demanding an answer RIGHT NOW. I'm asleep. My phone is lighting up. And I know if I don't respond they'll spiral.

I have 22 active deals. I cannot give every buyer my personal cell. But I also can't afford to miss anything.

I gave my number to one seller two years ago. She still texts me. The deal closed in 2023.

The Problem

Your business communication is split across three places it was never meant to live.

You're not disorganized. The tools are wrong. Your business communication is split across a personal phone, a personal email, and a memory that can't keep up with 30 active transactions.

Ghosted

Client. Personal phone. Family dinner just ended. This is your life now — unless you draw a line.

Can't find it

Where did you write down the inspector's callback number? Nowhere. Because it was a phone call. And phone calls disappear.

All night long

Your phone is on the nightstand. Lit up. Again.

The Answer

SIGNARA Connect

SIGNARA Connect gives every agent a dedicated business line — calls, texts, and email — all routed through SIGNARA, logged to the right deal, and read by CARI.

📞
Dedicated number

Your clients call and text a real phone number — not your personal cell.

🧠
CARI reads everything

Every message is logged to the deal. CARI knows what was said and when.

🔒
Your personal life stays private

Clients never get your real number. You go dark when the deal closes.

📧
Business email included

A @signara.io address tied to your account — not your Gmail.

The Smart Move — Made Smarter

You've already thought of this.

A lot of agents already figured out the second phone problem. They use Google Voice — a separate number that forwards to their cell. Smart. But Google Voice doesn't know anything about your deals.
