From Zero to SaaS: How I Built a Scalable Product Using Lean Methodologies

Building My SaaS When I Knew Nothing (And No Budget)

Let’s be real – I had no business launching a SaaS product. No venture capital. No team. Just a spreadsheet of ideas and determination. Here’s how lean methodologies got me from zero to 10,000+ users.

The turning point? Realizing SaaS success isn’t about flawless code. It’s about three things: validating fast, building only what matters, and adapting quicker than your doubts.

The Tech Stack That Didn’t Crush My Soul

Tools That Grew With My Users

My rule? Never fall in love with technology. Choose tools that:

• Frontend: Next.js (for those sweet SSR benefits)
• Backend: Good ol’ Node.js + Express
• Database: PostgreSQL – still my relational rock
• Hosting: Vercel’s free tier (then AWS when we scaled)
• Payments: Stripe – because rolling your own is financial Russian roulette

// Keeping Stripe happy - my webhook security blanket
const stripe = require('stripe')(process.env.STRIPE_SECRET);

app.post('/webhook', (req, res) => {
const sig = req.headers['stripe-signature'];
try {
const event = stripe.webhooks.constructEvent(
req.body,
sig,
process.env.STRIPE_WEBHOOK_SECRET
);
handleEvent(event); // Our money-making function
} catch (err) {
return res.status(400).send(`Webhook Error: ${err.message}`);
}
});

Why This Combo Worked

Early-stage SaaS development needs speed, not scalability porn. This stack let me:

“Ship today’s feature before tomorrow’s doubt kicks in”

How My Embarrassing MVP Got Paying Customers

The 30-Day Reality Check

My first version had fewer features than a to-do list app:

• Login (thanks Auth0)
• One core automation workflow
• A dashboard that barely qualified as “reporting”

The result? Real people paid real money. Why? Because it solved their immediate pain – ugly solutions beat pretty abstractions.

My Brutal Feature Filter

This scoring system killed zombie features:

| Feature | Dev Effort | User Screams | Cash Impact | Total |
|---------------|------------|--------------|-------------|-------|
| AI Assistant | 4 | 5 | 3 | 12 |
| Custom Charts | 3 | 4 | 4 | 11 |
| Mobile App | 5 | 2 | 2 | 9 |

Anything under 10 got axed. Saved me 3 months of wasted development.

Roadmapping Without Losing My Mind

The 90-Day Cycle That Actually Works

Forget annual plans. My rhythm:

• Weeks 1-4: User interviews (actually using the product with them)
• Weeks 5-8: Code the most begged-for feature
• Weeks 9-12: Fix what makes users swear

Transparency = Trust = Sales

Sharing our roadmap publicly felt like underwear modeling. But enterprise deals increased 27% when clients saw:

“We’re committed, but not delusional about our priorities”

Growth Hacks That Didn’t Require a Marketing Team

The $500 Reality Check

Before coding a single line:

1. Threw up a landing page (with broken “Sign Up” button)
2. Ran $20/day Facebook ads targeting actual humans
3. Measured how many clicked vs. actually tried to sign up

38% conversion rate told me this wasn’t just my mom being nice.

Shipping Like a Maniac

Our CI/CD pipeline became my therapy:

# GitHub Actions - my silent co-founder
name: Ship It Already

on:
push:
branches: [ main ]

jobs:
deploy:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Install Dependencies
run: npm ci
- name: Build
run: npm run build
- name: Deploy
uses: vercel/action@v23
with:
vercel-token: ${{ secrets.VERCEL_TOKEN }}

12+ deploys/week meant users saw progress daily.

Bootstrapping Without Starving

Profit From Day 30 or Die Trying

My survival rules:

• Pre-sold annual licenses (validation check + cash injection)
• Partner integrations with revenue sharing
• Usage-based pricing from day one (no “enterprise plan” fantasy)

Bank Account Therapy

Automated money rules saved my business:

“Every dollar gets split before I touch it: 25% growth fund, 30% taxes, 45% oxygen money”

Only Metrics That Made Me Swear

Ignored vanity metrics. Lived by:

• LTV:CAC: 1.3 (the magic break-even zone)
• Activation Rate: 58% (did they actually use it?)
• Revenue Run Rate: $27K → $153K in 9 months (proof we weren’t imaginary)

Truth Bomb: Perfect Is the Enemy of Paid

My SaaS journey taught me:

1. Build fast, charge faster
2. Features don’t pay bills – solved problems do
3. Financial discipline isn’t sexy… until payroll hits
4. User feedback > your brilliant ideas

Remember: Your code doesn’t need to be beautiful. Your solution needs to be necessary. Stop polishing. Start charging.
