Your SaaS platform goes live the moment a second paying customer logs in and can't see the first customer's data. That's multi-tenant architecture — row-level security, isolated workspaces, real separation. Not just authentication. Not just separate accounts. True data isolation where your infrastructure serves hundreds of tenants without a single security boundary crossing. Marketplaces compound that. Now your platform connects buyers to sellers, handles escrow through Stripe Connect, calculates commissions across disputed transactions, and processes refunds when a buyer ghosts mid-order. One misconfigured payout flow destroys seller trust permanently. In marketplaces, sellers leaving is extinction. Under the hood: subscription billing wired through Stripe (failed charges, proration, disputes), dashboards that surface business-critical metrics, admin controls so you can actually run the operation, and your core differentiation logic — the matching algorithm, the commission structure, the access rules that make your platform worth building. That last part is the real engineering. We've built authentication and tenant isolation so many times it's reflex. But your specific business logic? That's what we architect together in week one.

Häufige Fragen
How much does it cost to build a SaaS MVP?
A production-quality SaaS MVP runs $50,000 to $100,000 and takes 8 to 12 weeks. That's not a throwaway prototype -- it's a real foundation with multi-tenant architecture, Stripe subscriptions, and the core logic that makes your platform worth using. Post-MVP iteration is $5,000 to $15,000 per month. And for the right project, equity participation is on the table.
What is the difference between a prototype and a production MVP?
A Lovable or Bolt prototype looks great in a demo -- genuinely. But it can't handle real users, real payments, or real data isolation. A production MVP has proper multi-tenant architecture where every customer's data is actually isolated, Stripe integration that handles subscriptions and billing edge cases without breaking, and infrastructure that doesn't require a full rebuild the moment you get traction. That's the difference you're paying for.
Can you build a two-sided marketplace?
Yes. We've built marketplaces with buyers and sellers, escrow payments via Stripe Connect, search and filtering, review systems, and admin controls. Multi-vendor catalog management, commission calculations, payout scheduling, dispute resolution -- we've worked through all of it. NAS handles 137K listings and it still performs.
What about subscription billing and pricing tiers?
We wire Stripe Billing for subscription management -- monthly and annual plans, multiple pricing tiers, usage-based billing, free trials, coupon codes, upgrade and downgrade flows. We built a 4-tier subscription system with 30+ feature flags controlled per plan level. So when you say "premium users should see X but basic users shouldn't," we know exactly how to architect that.
Do you build mobile apps or just web platforms?
We build web-first platforms that are fully responsive and work great on mobile browsers. For native mobile apps, we can build with React Native or connect your platform to a separate mobile frontend. Honestly though -- most SaaS products and marketplaces perform better as progressive web apps than native apps, especially at MVP stage. Don't add that complexity until you've proven the core product.
What if my idea needs to pivot after launch?
The architecture is modular on purpose. We can swap features, add new user roles, change the billing model, or pivot the core value prop without rebuilding from scratch. Most of our SaaS clients iterate significantly in the first 6 months -- because real users always have opinions your spec didn't anticipate. That's fine. We build for it.
