How Arch Connects to ServiceTitan: 5 Minutes to Smarter Retention and Lead Discovery

Written by Philipp Krinner, CEO & Co-Founder of Arch AI
Last Updated: March 2026

If you're running an HVAC, plumbing, or electrical company on ServiceTitan, you already have a goldmine of customer data sitting in your account. Job history, revenue per customer, call records, membership status. The problem is that none of it is working for you proactively. Arch changes that. One integration, five minutes, no disruption to your existing workflows.

Here's exactly how it works.

What the Integration Does

Arch connects to your ServiceTitan account through the ServiceTitan marketplace in view-only mode. That means Arch can read your data but never modifies, overwrites, or writes anything back unless you specifically request it.

What Arch reads: customer records, job history, revenue data, service timelines, call logs, and membership information. Essentially a full 360-degree view of every customer relationship in your system.

Setup takes about five minutes per tenant. There's no software to install on your machines, no workflow changes for your team, and no downtime. Your dispatchers, techs, and CSRs won't notice a thing.

What Happens After You Connect

The integration is the starting line, not the finish line. Here's what Arch does with your data once it's connected.

Step 1: Your Customer Data Gets Enriched

ServiceTitan tells Arch who your customers are and what work you've done for them. Arch layers in data that ServiceTitan doesn't have: real estate transactions, property demographics, and financial signals.

A customer record that used to be "Jane Smith, last serviced June 2024, $3,200 lifetime value" becomes a complete profile. Arch now knows if Jane recently sold her home (a major churn trigger), whether the house has an aging system based on permit history, and what her neighborhood's replacement patterns look like.

This enrichment is what makes everything downstream possible.

Step 2: AI Builds a Prediction Model for Your Business

Arch doesn't use a generic, one-size-fits-all algorithm. It trains a bespoke AI prediction model on your specific data: your customers, your service history, your geography, your pricing patterns.

The model identifies three things:

Which existing customers are at risk of churning (and why)
Which customers have upsell or cross-sell opportunities hiding in their service history
Which prospects in your territory look most like your best customers

This is a model built for your business, not the industry average.

Step 3: Retention and Lead Discovery Run Automatically

Once the model is trained, Arch acts on what it finds.

At-risk customers get re-engaged before they leave. The system detects early churn signals, reads technician notes, and triggers the right offer at the right time through email, direct mail, or digital channels.

For new customer acquisition, Arch's AI analyzes permits, property data, and market signals to surface prospects who are actually ready to buy. Not just anyone in your zip code.

Campaigns deploy automatically. You get the output of a marketing team without the headcount.

Step 4: You See Exactly What's Working

Every campaign Arch runs includes built-in holdout groups, matchback tracking, and full attribution across every touchpoint: calls, emails, QR codes, and direct mail responses.

You'll know which campaign generated revenue and which didn't. No guesswork, no vanity metrics. Just clear data on what moved the needle.

Security and Data Protection

Your ServiceTitan data is sensitive. Arch treats it that way.

Arch operates in view-only mode. Your data is encrypted at rest and in transit. Infrastructure runs on AWS. Access is controlled through role-based permissions, and only authorized personnel who need access to deliver the service can view customer data. Arch will permanently delete your data from its systems upon request.

Authentication is handled through secure, server-side sessions with CSRF protection. No tokens are stored in the browser or exposed in client code.

Why This Matters for Your Business

Our Q4 2025 study of 85+ home services companies found a massive spread in customer retention: the best operators churn just 7% of customers annually. The average sits at 40%. That gap represents real revenue walking out the door every month.

Here's the other number that matters: it costs 13x more to acquire a new customer than to reactivate an existing one. Most contractors pour money into lead generation while their existing customer base quietly erodes.

The Arch integration with ServiceTitan is the mechanism that flips this equation. It turns the data you already have into a system that retains customers, finds new ones, and proves what's working, all without adding headcount or changing how your team operates day to day.
