One of the most interesting posts on Hacker News right now: a developer wanted to build vertical SaaS for pest control, so they got a job as a pest control technician first.
207 points and climbing. And the comments are gold.
Why This Story Matters
Most developers build software for other developers. The market is crowded:
- 50,000+ developer tools on Product Hunt
- Every "AI wrapper" has 10 competitors
- Developer tools have sophisticated, demanding users
But niche industries like pest control, plumbing, landscaping, and HVAC are:
- Underserved — still using paper or Excel
- Willing to pay — $50-200/month is nothing for a business
- Low competition — no developer wants to build for exterminators
- Sticky — once adopted, businesses rarely switch
The Vertical SaaS Opportunity
| Industry | # Businesses (US) | Avg. Software Spend | Competition |
|---|---|---|---|
| Pest Control | 35,000+ | Low | Very low |
| Plumbing | 120,000+ | Low | Low |
| Landscaping | 600,000+ | Low | Low |
| HVAC | 120,000+ | Medium | Medium |
| Developer Tools | N/A | High | Extreme |
What the HN Post Teaches
1. Domain knowledge > technical skills
The developer didn't just research pest control — they worked in it. They learned:
- The actual workflow (not what they assumed)
- Pain points that software could solve
- Language and terminology customers use
2. Boring problems = profitable solutions
Scheduling, invoicing, route optimization, customer communication — these aren't exciting, but they're worth paying for.
3. Competition is different in niches
In developer tools, you compete with Y Combinator-funded startups. In pest control software, you compete with... spreadsheets.
For Developers Considering This Path
If you have a technical background and want to build something profitable:
- Pick an industry nobody wants — the less sexy, the better
- Talk to 20+ businesses before writing code
- Charge from day 1 — these businesses understand paying for tools
- Keep it simple — they don't need AI, they need scheduling that works
Discussion
- Would you build software for a non-tech industry?
- What's the most boring industry you think has a big software gap?
- Have you ever worked in a non-tech job to understand the domain?
- Is vertical SaaS a better path than developer tools for indie hackers?
I've been in the developer tools space (120+ open source tools) and honestly, the competition makes it incredibly hard to get traction. The pest control approach is tempting.
What niche would you build for?
