Building a Profitable Niche SaaS in 90 Days

The Niche SaaS Opportunity

Most founders dream of building the next Salesforce. The smarter play — especially in India — is building the Salesforce for interior designers, or ayurvedic clinics, or regional language tutors.

A niche SaaS doesn't need millions of users. It needs a specific group with a specific expensive-enough problem. The math: 50 paying customers at ₹5,000/month = ₹25 lakh ARR. In a focused niche, achievable by a single founder within 12–18 months.

Days 1–15: Pick the Right Niche

The niche must satisfy three criteria:

You can reach them. You know some already, or there are communities where they gather.

They have money. Not just a problem — one they're currently paying to solve imperfectly. CA firms, clinics, logistics companies, legal firms all have established software budgets.

The problem is shared. Ask 5 people in the niche what their biggest operational headache is — if you hear the same answer 3+ times, that's your product.

Conduct 10 customer discovery calls. Ask: What takes the most time? What software do you hate? What would you fix if you could? Don't pitch. Just listen. The product idea emerges from these conversations.

Days 16–30: Validate Before Building

Write a one-page description of what you're building. Add 'Join the waitlist — early access at ₹2,500/month.' Send to the 10 people you interviewed.

If 3–4 express genuine interest, that's a signal. If 2–3 pay a token advance, you have pre-validation.

Define V1 precisely: 5–7 features that solve the core problem. Anything else is V2. Scope expansion kills 90-day projects.

Days 31–60: Build the Minimum Version

Goal: working product in front of paying beta customers. Not perfect — working.

Tech stack for speed: Next.js + Supabase + Razorpay gets you auth, database, and payments in days.

Build: User registration, the core feature that solves the main problem, basic billing, a way to contact support.

Skip: Admin panel, advanced analytics, multiple pricing tiers, API integrations (unless the core product requires it).

Days 61–75: Onboard Beta Customers

Charge beta customers. Free users give you engagement but not real feedback. When someone paid ₹2,500, they'll tell you exactly what doesn't work.

Onboard personally — walk them through on a call, watch them use it, take notes on every confusion point. Fix the top 5 issues. By day 75, you should have a product beta customers use regularly and find genuinely valuable.

Days 76–90: Launch to a Small Audience

Launch is not a big moment — it's the beginning of a sales process.

Targeted outreach: 100 potential customers via LinkedIn, associations, WhatsApp groups. Personal messages, not mass email. Offer a 14-day free trial.

One community: Find where your customers gather online. Post about the problem you're solving. People respond; follow up directly.

Founder content: 3 LinkedIn posts in two weeks about the problem you're solving. People in your niche will see it and reach out.

Target: 5 paying customers by day 90. This proves the business works.

After 90 Days

At 5 customers, you have proof. At 20, traction. At 50, a business.

The niche focus is your advantage. You know these customers better than any large competitor. You iterate faster. You support them better. You understand their language. The niche isn't a limitation — it's the foundation.
