Should You Validate Before Building Your SaaS?
Nine out of ten startups fail. CB Insights pins the top reason on one thing: building a product nobody wants. So before you write a single line of code, prove the idea holds up. Three steps do it. Our SaaS development team partners with founders to take an idea all the way to a launched product.
Step 1: Landing page test. Put up a one-page site that describes the product. Add a waitlist signup. Then spend $200 on Google Ads and watch what happens. Fewer than 3% of visitors signing up tells you the positioning is off, or the pain just isn't sharp enough yet.
Step 2: 10 customer interviews. Talk to real potential users. Not friends. Not family. Actual people who live with the problem you want to solve. We ask two questions: 'How do you handle this today?' and 'What would you pay for something better?' When someone can't name the pain in concrete terms, it usually isn't a real problem.
Step 3: Pre-sell. Offer early access at a discounted annual rate and see who actually reaches for their card. Get 5 of 50 prospects to pay before the product even exists, and you have validation. Nobody pays? Then what you have is a feature request, not a business. For the full lifecycle, walk through our MVP development guide.
What Is the Best Tech Stack for a SaaS MVP?
Speed and cost win most of these decisions. So here's the stack we reach for on roughly 80% of the SaaS products we build:
Frontend: Next.js 15 (App Router). You get server-side rendering that search engines love, React's huge component ecosystem, and zero-config deploys on Vercel. Building an internal tool where SEO doesn't matter? Vite plus React is lighter. On the backend side, dig into Node.js for SaaS backends.
Backend and database: Supabase. It's PostgreSQL with auth, real-time subscriptions, and Row Level Security baked in, plus a free tier that's genuinely generous. A production database, and you never touch the infrastructure. Prefer real-time-first and don't care about SQL? Firebase is the swap.
Payments: Stripe. Subscriptions, invoicing, a customer portal, tax handling. It's all there. Stripe Checkout has you live in hours, not weeks. Yes, the 2.9% + $0.30 fee stings a little, but that's the price of never building a payment system yourself.
Email: Resend. Your transactional mail (welcome notes, password resets, invoices) written as React Email templates. Free up to 3,000 emails a month.
Hosting: Vercel. Free on the hobby plan, $20 a month for Pro. HTTPS, a CDN, and preview deployments come automatically. No DevOps to babysit.
Add it all up and an MVP serving up to 1,000 users runs $0-$45 a month in infrastructure. Now compare that with enterprise stacks that bill $500+ before your first user has even signed up.
Our SaaS development team ships end-to-end product delivery on this exact stack as your build partner. And the SaaS development FAQ covers the questions founders ask us most.
What Features Does Your SaaS MVP Actually Need?
Your MVP needs five things. Five. Everything else can wait for v2.
1. Authentication. Email/password plus Google OAuth. That's it. Skip SSO. Skip SAML. Skip magic links. Supabase Auth handles all of this for you out of the box.
2. The core value proposition. The ONE thing your product does better than everything else out there. Two or three screens, tops. If you can't say what that core value is in a single sentence, your MVP scope has already grown too wide.
3. Billing. Stripe Checkout, two or three pricing tiers, and a clean free-trial-to-paid path. Offer both monthly and annual billing. Hand users a customer portal so they manage their own subscription without emailing you.
4. Settings. Profile edits, password changes, billing management, notification preferences. Boring? Sure. Still necessary.
5. Onboarding. A three-step wizard that gets people to the 'aha moment' inside two minutes. Drag it out past that and you'll watch 60% of your signups quietly disappear.
And the things that do NOT belong in your MVP? An admin dashboard. Analytics. Integrations. Multi-language support, a mobile app, custom domains, team management, audit logs. Every single one of those is a v2 problem, not a launch-day one.
Can You Build a SaaS MVP in 8 Weeks?
This timeline assumes two or three developers working full-time. If you'd rather build with a dedicated team than staff it yourself, our full-stack developers can start right away:
Week 1-2: Design and architecture. Wireframes in Figma, and we mean wireframes, not pixel-perfect mockups. Then the database schema, the API contract, the auth flow, the payment flow. Stand up the deployment pipeline now too. CI/CD belongs on day one, not day 50.
Week 3-5: Core build. Authentication, the main feature screens, database models, API endpoints. Ship to staging every day. Skip the polish for now and chase functionality only.
Week 6-7: Integrations and polish. Now wire up Stripe billing, email notifications, the onboarding flow. Add error handling, loading states, empty states. This is the stretch where the product finally starts to feel real.
Week 8: Launch prep. Push to production, point the custom domain, set up monitoring (Sentry for errors, plus basic analytics). Invite 10 beta users, fix what their feedback surfaces, then go live on the web or App Store.
A team out of India runs you $15,000-$30,000. A US team, $40,000-$80,000. The deliverable doesn't change either way: a live SaaS product that's ready to take paying customers.
How Do You Get Your First 100 SaaS Users?
Building the product is half the job. Getting people to use it is the other half, and honestly the harder one. Here's a launch playbook that actually holds up:
Pre-launch (Week 6-8). Build in public on Twitter and LinkedIn. Post screenshots, the architecture calls you made, the lessons you picked up the hard way. You're growing an audience before the product even ships. Aim for 50 waitlist signups.
Day 1: ProductHunt. Submit on a Tuesday, when traffic peaks. Come prepared with 5 sharp screenshots, a 90-second demo video, and a tagline that lands. Line up 10 friends who'll upvote and leave real comments, not one-word ones. Shoot for top 5 of the day.
Day 2-7: Direct outreach. Email 50 people who fit your ideal customer profile. Not a pitch. A genuine ask: 'I built this to fix X. Would you try it and give me 15 minutes of honest feedback?' Throw in a free month as a thank-you.
Week 2-4: Content. Write 3 blog posts about the problem you solve, not about your product. Drop them on HackerNews, the subreddits that fit, and LinkedIn. Close each one with a light, almost offhand mention of what you built.
Week 4-8: Iterate. Your first 100 users will show you what's missing and what confuses them. They'll also show you, by behavior, which parts they actually touch. Whatever they ask for most? That's your v2 roadmap, handed to you.
How Do You Scale Beyond the MVP?
So the MVP worked. You've got 100 users, a handful of them paying. Now what?
Do NOT rewrite. The classic post-MVP mistake is deciding the codebase 'isn't good enough' and starting from scratch. Resist it. Your codebase is fine. It has users. It makes money. Refactor a piece at a time, never all at once.
Add analytics before you add features. You can't prioritize a roadmap on hunches. Drop in Mixpanel or PostHog and watch three things: activation (the share of signups who finish onboarding), retention (who comes back after 7 days), and revenue (MRR, churn, LTV). Then build only the features that move those numbers.
Hire for the bottleneck. If feature velocity is what's holding growth back, bring on a developer. If acquisition is the wall, hire for marketing instead. And if churn is the real problem, go talk to the customers who left before you hire anyone at all.
