ServiceTitan went public in 2024 at a valuation above $9 billion, building primarily on HVAC, plumbing, and electrical contractors. It is one of the largest vertical SaaS exits in the last decade. And the market it targets is still, by most estimates, less than 20% penetrated by software.
The skilled trades sector processes roughly $1.8 trillion in annual revenue across North America. The businesses in it schedule crews by phone, track job costs in spreadsheets, and invoice customers through whatever came with their accounting software. That is not a gap that ServiceTitan missed. It is the natural ceiling of what any single platform can reach.
Where the current tools stop
The major platforms in field service software target businesses above a threshold. ServiceTitan is designed for HVAC and plumbing contractors doing $3M or more in annual revenue. Jobber fits cleanly for smaller operators. Housecall Pro competes in the same tier as Jobber. Each has carved out a position by going deep in a segment.
Below the ServiceTitan tier, and inside specific sub-verticals, the software coverage is uneven. A roofing contractor managing storm restoration crews has scheduling needs that differ meaningfully from a residential HVAC company. A specialty electrical subcontractor doing commercial buildouts tracks labor, materials, and change orders differently than a service-call shop. General field service software forces these businesses to adapt their workflows to the tool rather than the reverse.
That gap compounds over time. Owners who try a general tool, find it frustrating, and revert to spreadsheets have not been saved by a better product. They are still running on manual processes, and their frustration has increased their willingness to pay for something built for their specific trade.
The economics of a mid-market trades business
A roofing contractor doing $5M in annual revenue typically runs with margins in the 8 to 15% range. That means $400K to $750K in annual profit on a good year, before owner compensation. Most of that margin sits in job costing accuracy, labor utilization, and change order capture. Software that improves any one of these by 2 percentage points is worth $100K per year to this owner.
At that value level, a SaaS product priced at $1,500 to $3,000 per month is not an expensive purchase. The question buyers ask is not whether the price is fair. The question is whether the product will actually work for how they operate. That trust barrier is where operator founders have a genuine structural edge.
Why operator founders win in trades software
An outside team building for HVAC contractors will spend 18 months learning what an operator who ran an HVAC company already knows cold. They will ask questions in customer discovery that reveal how much they do not understand. Buyers notice.
An operator founder who ran field operations for a roofing company walks into a sales call and names the specific problems before the prospect does. They know that the dispatcher's workflow on a busy Monday morning differs from the project manager's end-of-week close. They know which fields matter on a job ticket and which ones never get filled in. That specificity is not a sales technique. It is domain knowledge, and prospects recognize it.
This is the core of what vertical SaaS produces at its best: a product that fits a specific industry's actual processes rather than approximating them. Operator founders do not need to hypothesize about what contractors want. They have lived the operational tradeoffs firsthand.
The sub-verticals worth watching
The trades sector is not monolithic. Within field service, several sub-markets have high software frustration and low current penetration:
- Specialty subcontractors (fire suppression, low-voltage, elevator service) with complex regulatory documentation requirements and multi-site service contracts
- Residential restoration contractors (water damage, mold remediation) who work inside insurance claim workflows and need tight integration with carrier systems
- Landscape maintenance companies managing seasonal routes, chemical application records, and recurring service agreements across hundreds of properties
- Commercial cleaning services with shift-based staffing, quality inspection workflows, and multi-building contract structures
Each of these is a real vertical with thousands of businesses, not a niche. Each has workflows that look similar to other field service businesses on the surface but differ enough in practice that general tools fail at the margin cases that matter most.
What a focused product can do that a platform cannot
A platform like ServiceTitan must serve HVAC, plumbing, and electrical well enough that any contractor in those trades can use it. That breadth creates a floor, not a ceiling. A focused product serving only landscape maintenance companies can build features that a horizontal platform will never prioritize: seasonal route optimization, water usage reporting, chemical application logs required for state licensing, client portal access for HOA property managers.
Depth beats breadth in vertical markets where the workflows are genuinely different. The businesses that pay the most for software are the ones whose process-specific needs get ignored by the horizontal players. That is the target.
If you have spent time running or operating a trades or field service business and are thinking about building software for your former industry, start with the workflows you found most frustrating. The frustration is the signal. For more on identifying the right starting point, see The Operator Founder Advantage.
