SaaS Product Building
From concept to scale. I build complete SaaS products with focus on product-market fit, scalable architecture, and sustainable growth.
What is SaaS Product Building?
SaaS (Software-as-a-Service) means delivering software over the internet via subscriptions, rather than one-time purchases. SaaS product building requires different thinking than traditional software: multi-tenant architecture, payment processing, scaling infrastructure, customer onboarding, analytics tracking, and retention strategies.
I specialize in building complete SaaS products: from validating your idea with an MVP, to building the full product, to scaling to thousands of paying customers.
The SaaS Journey
Phase 1: Validation (Weeks 1-4)
Validate your idea: interviews, market research, competitive analysis, and user feedback. Define core features for MVP.
Phase 2: MVP (Weeks 4-12)
Build minimal viable product with core features only. Focus on getting it in front of real users quickly. Stripe integration for basic monetization.
Phase 3: Launch (Weeks 12-16)
Beta testing, customer onboarding, analytics setup, and launch to early adopters. Gather feedback and identify pain points.
Phase 4: Scale (Months 4+)
Optimize architecture, add advanced features, implement customer support systems, and focus on retention and growth.

Multi-Tenancy Architecture
SaaS products serve multiple customers (tenants) from a single codebase. This requires careful architecture to ensure data isolation, per-tenant customization, and efficient resource usage.
| Aspect | Considerations |
|---|---|
| Data Isolation | Separate schemas/databases per tenant vs. shared database with row-level security |
| Customization | White-labeling, custom domains, feature toggles per tenant |
| Performance | Query optimization, caching strategies, load balancing |
| Billing & Quotas | Usage tracking, overage charges, seat-based pricing, feature limits |

View case study →SaaS Pricing Models
📊 Tiered Pricing
Starter ($9), Pro ($29), Enterprise ($99+). Each tier unlocks more features. Best for products with clear feature differentiation.
📈 Usage-Based
Pay-per-use: $0.10 per API call, $5 per 1000 documents processed. Fair pricing that scales with customer value.
👥 Seat-Based
$5 per user/month. Users invite teammates. Good for collaboration tools and enterprise software.
Frequently Asked Questions
How do I know if my idea is viable for SaaS?▼
I help validate during discovery: market sizing, user interviews, competitive analysis, and problem validation. If customers aren't willing to pay for your solution, we iterate before building. Validation typically takes 2-4 weeks.
How much does it cost to build a SaaS product?▼
MVP: $15,000-40,000 (2-3 months dev). Full product: $40,000-100,000+ (5-6 months). Varies based on complexity, team size, and features. I offer flexible engagement options including revenue-share for promising ideas.
Should I use a SaaS framework (like Supabase) or build custom?▼
Most SaaS start with custom builds for flexibility. Frameworks speed up development but limit customization. I recommend custom builds for products needing differentiation or complex business logic.
How do I handle payment processing securely?▼
Use Stripe (recommended) - they handle PCI compliance and security. Never store credit cards directly. I implement Stripe correctly with webhooks for subscription management, invoicing, and refunds.
What about hosting, scaling, and infrastructure?▼
I set up production-grade infrastructure on AWS or similar. Auto-scaling handles growth. Costs start at $200-500/month for small, scale to thousands with growth. Monitoring and alerts prevent downtime.
How do I know when to hire a technical co-founder?▼
After MVP validation with real paying customers (3-5 paying users). At that point, growth requires more development speed than solo building allows.
