Sell into insular, relationship-driven industries only after earning lived credibility outsiders cannot fake, then embed a single system of record so deeply that added seats, modules, and volume make leaving unthinkable.
ServiceTitan
ServiceTitan is the cloud operating system for the trades, running the back office of plumbing, HVAC, and electrical contractors: call booking, dispatch, scheduling, invoicing, marketing attribution, payroll, payments, and financing. The through-line across its stories is that lived credibility with tradespeople opened a door that outsiders could not, and once inside, a single deeply embedded system of record compounds through more seats, more modules, and more transaction volume until leaving becomes nearly unthinkable.
Founder-Market Fit: sons of a contractor and a plumber selling to contractors
The problem. Home-services contractors are a relationship-driven, insider industry that reflexively dismisses software salespeople who have never turned a wrench or ridden in a service truck. Enterprise vendors had ignored the trades for decades, and the ones who tried struggled to earn the trust needed to become the system that runs a contractor's whole business.
The approach. Co-founders Ara Mahdessian (CEO) and Vahe Kuzoyan (President) were the sons of trade business owners: Mahdessian's father a contractor, Kuzoyan's father a plumber. They built ServiceTitan explicitly to fix the paper, whiteboard, and QuickBooks chaos they had watched their parents endure, giving them native credibility with the exact buyer they were pitching.
How it solved it. That insider standing let them win trust in a skeptical market and grow to over 8,000 customers and roughly $685 million in trailing revenue by their December 2024 IPO. The symbolism was made explicit when the founders' parents rang the Nasdaq opening bell on debut day.
Land and Expand: from core operations to Pro modules and payments
The problem. Selling one software seat to a plumbing shop is a small, capped deal. To build a large business on top of small and mid-sized trade contractors, ServiceTitan needed each account to grow in value over time rather than stay flat at its initial footprint.
The approach. Contractors land on core operations software, then expand: they add seats as they hire, layer on premium Pro products (Marketing Pro, Dispatch Pro, Scheduling Pro), and route payments and financing through the platform. Revenue rises as the contractor books more jobs and processes more money through ServiceTitan.
How it solved it. This expansion motion drove net dollar retention above 110% for 10-plus consecutive quarters, meaning existing customers spent more each year even before counting new logos. The S-1 candidly notes NDR drifted down roughly 7 points with scale, the strategist's caveat that SMB-trades accounts have a ceiling, so durable growth leans on new trades and new monetization layers.
Beachhead: highest-ticket residential HVAC and plumbing first
The problem. The trades span dozens of verticals (HVAC, plumbing, electrical, landscaping, pest control) across residential and commercial, each with distinct workflows. Trying to serve all of them at once would have produced shallow software that nailed none of them in an industry that punishes generic tools.
The approach. ServiceTitan planted its beachhead in the highest-pain, highest-ticket residential trades, HVAC and plumbing, where a missed call or bad dispatch directly costs thousands per job. It nailed that end-to-end workflow first, then expanded from that defensible core into adjacent trades and into commercial.
How it solved it. Owning the hardest residential workflows gave ServiceTitan a proven wedge it could replicate outward, building the customer base and product depth that carried it to roughly $961 million in FY2026 revenue on about 24% growth. Starting narrow and winning decisively beat spreading thin across a fragmented market.
Recurring Revenue: textbook vertical SaaS with usage on top
The problem. Vertical software for an unglamorous, distributed industry has to prove that recurring revenue can be both sticky and expandable, not a one-time license sale to a fragmented base of small businesses that churn easily.
The approach. ServiceTitan built classic subscription SaaS (seat-based fees for the operating platform) and layered usage-based revenue and transaction take on top through payments and financing, so the model captures both software subscriptions and a slice of the money flowing through contractors' businesses.
How it solved it. The mix produced durable, high-retention economics: gross dollar retention above 95% at the S-1 on roughly $685 million in trailing revenue, the kind of low-churn foundation that let ServiceTitan IPO at a roughly $8.9 billion valuation. The usage and payments layers turn a stable subscription base into one that grows with each customer's volume.
Switching Costs: the system of record you cannot rip out
The problem. A vendor that only handles one task is easy to swap. To defend its position, ServiceTitan needed to become so embedded in a contractor's daily operations that competitors could not dislodge it with a cheaper price or a single better feature.
The approach. ServiceTitan became the system of record for the entire business at once: dispatch, scheduling, quoting, invoicing, marketing attribution, payroll, and increasingly payments and financing all run through it. Each additional Pro module and payment integration deepens the dependency.
How it solved it. Because the platform runs everything simultaneously, ripping it out means re-platforming dispatch, billing, and payroll in one traumatic move, a switching cost that climbs with every module adopted. That entrenchment shows up in the numbers: gross retention above 95% and NDR above 110% for 10-plus straight quarters, evidence that customers stay and buy more rather than leave.
