Expanding a SaaS product into a new vertical costs most founders more time and money than it should, mostly because they treat it as a fresh start. This is a repeatable saas go-to-market strategy for a new vertical that builds on what you already have.
Every founder who has cracked one vertical eventually stares at the same whiteboard question: what does a saas go-to-market strategy for a new vertical actually require? The answer usually involves a lot of blank slides and the uncomfortable feeling that everything built for market one has to be rebuilt for market two. It rarely does. ServiceTitan launched as HVAC software in 2012. By the time it raised its Series H at a $9.5 billion valuation in 2021, it had expanded into plumbing, electrical, roofing, landscaping, and pest control. Each expansion wasn't a clean-sheet rebuild. It was a disciplined port of the same GTM engine into an adjacent workflow with different vocabulary, different buyers, and a narrow product delta.
That's the whole playbook. Port it, translate it, and plug the gaps.
The first instinct when entering a new vertical is to ask what the product needs to change. That's the wrong first question. Ask instead: what is actually different about how this vertical operates compared to the one you already serve?
For ServiceTitan moving from HVAC to plumbing, the core workflow was nearly identical: dispatch, scheduling, invoicing, customer history. The delta was narrow. Different parts catalogs, slightly different job types, a different search vocabulary for field technicians. That narrow delta told them how much product work was required before they could sell. In plumbing, not much. In a vertical with genuinely different compliance requirements or a radically different buying cycle, the delta is wider and the sequencing changes accordingly.
Map it concretely. What does a day in the life of your new target user look like that's different from your current one? Where does money move differently? What does a buying decision involve: a single owner-operator, a VP of operations, a procurement committee? Until you can answer those questions with specifics from actual conversations, any GTM strategy you build is guesswork dressed as a plan.
Hire the vertical before you market to it
Veeva Systems did one thing better than almost any vertical SaaS company before it: they hired people who had worked inside pharmaceutical companies before trying to sell to them. Peter Gassner, who founded Veeva in 2007, had learned from his time at Salesforce that generic CRM sold to life sciences was a losing proposition. Buyers didn't want software. They wanted to talk to someone who understood their regulatory environment, their field medical teams, their validation workflows. Veeva built that domain credibility into the sales team before they built the sales deck.
You don't need to hire an entire vertical team on day one. You need one or two people with genuine domain knowledge who can sit across from a prospect in the new vertical and not sound like they Googled the industry the night before. They'll correct your ICP assumptions, catch the terminology mistakes in your messaging, and tell you which trade associations actually matter and which ones everyone attends but nobody trusts. They'll also tell you the budget cycles in the new vertical, when deals close versus when they stall, and where the real objection actually lives. That intelligence is worth far more than the cost of those first two hires.
Your existing customers are the wedge
This is the part most founders underuse. Toast, which built its POS platform starting with full-service restaurants, didn't enter the quick-service segment cold. It followed customer referrals and existing relationships into fast-casual chains, then used those deployments as proof points to go deeper into QSR. The pattern repeats in almost every successful vertical expansion: the warmest leads in market two come from market one.
Before you spend anything on demand generation in the new vertical, go through your existing customer list and ask: who do these people know? Who have they mentioned? Who do they compete with that operates in the adjacent space? A warm introduction from a trusted peer cuts through skepticism that no amount of ad spend overcomes. In vertical SaaS, where buyers are often wary of vendors who haven't earned their domain credibility yet, that referral can take months off your sales cycle.
Reposition without forking the product
The temptation when entering a new vertical is to build a separate product, a separate brand, or a separately packaged version of the platform. Sometimes that's right. More often it's an engineering and product management tax you're paying before you've confirmed the market will buy. Procore, which built construction project management software starting with general contractors, expanded into specialty trades: mechanical, electrical, plumbing, without forking the product. They built vertical-specific modules and vertical-specific positioning layered on top of the core platform.
What you can do quickly, without a separate product fork, is change how you talk about what you already have. A different homepage, different case studies, different ad creative, different conference presence. If your core product solves 80% of the new vertical's problem, lead with that before investing in the remaining 20%. Sell into the new vertical, find out exactly where the product breaks, and build those gaps deliberately rather than speculatively.
The channel that worked in vertical one probably doesn't transfer
This is where a lot of expansions quietly fail. A founder who grew their first vertical through a specific trade publication or conference circuit assumes the equivalent exists in the new market and will work the same way. Sometimes it does. Often the conversion rates and cost structure are completely different, and founders only discover that after burning significant budget.
In HVAC, contractor Facebook groups are a genuine acquisition channel. In enterprise construction, they're not. In pharmaceutical compliance software, a relationship with a handful of trusted consultants can drive significant pipeline. In a consumer-adjacent vertical, that model doesn't exist. Research the actual information diet of your new target buyer: where they go to learn, who they trust, what they read. Then build a channel map from that, not from whatever you used last time.
Pricing deserves the same audit. What you charge in your current vertical is a data point, not a baseline. Procore charges construction firms based on annual construction volume, a pricing model built specifically for that market's unit economics. The willingness to pay in your new vertical depends on what the problem costs buyers if unsolved, how much revenue a single deployment represents to them, and what alternatives they're currently using. Transplanting your pricing model wholesale, without testing those assumptions, is how you leave money on the table or lose deals you should have won.
The saas go-to-market strategy for a new vertical that actually works isn't particularly bold. It's methodical: map the workflow delta before touching the product, hire domain credibility before you need to sell with it, use existing customer relationships as your first wedge into the new market, reposition before you rebuild, and audit the channel from scratch rather than assuming it transfers. ServiceTitan didn't become a multi-billion dollar platform by guessing what plumbers needed. They talked to plumbers, hired people who understood them, and ported a GTM motion that was already working. The blank whiteboard is optional.
