SaaS development from architecture to production
We build multi-tenant SaaS products with the infrastructure decisions made correctly from day one. Auth, billing, permissions, and deployment pipelines included.
No commitment. 45 minutes. Walk away with clarity.
The decisions that make or break a SaaS product
Most SaaS failures are not product failures, they are architecture failures. A database schema that cannot support multi-tenancy. A billing integration bolted on six months in. Auth that cannot handle SSO when an enterprise client requires it. Getting these right at the start costs a fraction of fixing them after you have paying customers.
What we build
Multi-tenant architecture
Row-level security, tenant isolation, and data partitioning built from day one. Adding a customer never means changing your schema.
Billing and subscriptions
Stripe integration with usage-based billing, tiered plans, trial management, and dunning flows. The billing edge cases are handled.
Auth and permissions
User auth, role-based access control, SSO/SAML for enterprise, and audit logging. Security is not an afterthought.
Admin and analytics
Internal admin panel, customer health dashboards, and usage metrics. Visibility into your product from day one.
How we work
Architecture review
Before writing code, we define the data model, tenant strategy, and infrastructure plan. This is where expensive mistakes get prevented.
Build in sprints
Working software every two weeks. You see the product taking shape, not a status update.
Launch and scale
Deployment pipelines, monitoring, and runbooks delivered at launch. You get a production system.
What shipped
12 clients in month one
A B2B workflow platform launched with 12 enterprise clients in month one. Multi-tenant architecture handled isolation without custom code per tenant.
MVP to SOC 2 in 8 months
A healthcare SaaS went from MVP to SOC 2 audit in 8 months. The architecture made compliance documentation straightforward.
$2M+ subscription revenue
GSD SaaS products have processed over $2M in subscription revenue across client deployments in the first year post-launch.
Why teams choose GSD
Architecture-first thinking. We have seen what happens when SaaS products skip the architecture conversation. We do not let that happen on our projects.
Full-stack ownership. Frontend, backend, infrastructure, CI/CD, monitoring. One team owns the whole system.
You own everything. Source code, infrastructure credentials, documentation. No lock-in.
One of our SaaS clients launched a B2B platform that hit $2M ARR within 18 months. They started with a clear architecture plan, shipped an MVP in 8 weeks, and iterated from real user feedback. No wasted features. No rewrites.
Another team came to us after their first vendor delivered a platform that could not scale past 500 concurrent users. We rebuilt the core with proper multi-tenant architecture and auto-scaling. Six months later they onboarded their 10,000th user without a single outage.
Kyla Sherwood, Head of Brand Engagement at Felt Right, said GSD is “a fantastic partner” who “never shies away from a challenge.” That approach drives every SaaS project we take on.
Build it right the first time
Projects start at $75K. Architecture review is included in the discovery phase before you commit to a full build.
Common questions
How much does SaaS development cost?
Most SaaS products run $75K-$250K depending on scope. An MVP with core features and basic multi-tenancy sits lower. A full product with enterprise auth and billing sits higher. We scope everything in writing before any work starts.
How long does it take to build a SaaS MVP?
A focused MVP with core features, auth, and billing takes 12-20 weeks. Adding enterprise features, SSO, advanced permissions, audit logging, adds 4-8 weeks.
What tech stack do you use?
We use the stack that fits your product: React or Next.js frontend, Node.js or Python backend, PostgreSQL, deployed on AWS or GCP. We recommend based on your requirements and maintenance needs.
Do you handle infrastructure?
Yes. Deployment pipelines, containerization, database backups, monitoring, and alerting are included. You get a production system with runbooks.
What about compliance (SOC 2, HIPAA)?
We build with compliance in mind from the start. Proper access controls, audit logging, encryption at rest and in transit, and documentation. We work with your compliance team if you are pursuing certification.

Everything you need to know before getting started.
Most projects follow 2-week sprint cycles. An MVP typically takes 8 to 16 weeks depending on complexity. We provide a detailed timeline during the discovery phase before any commitment.
After a free discovery call, we scope your project and provide a fixed price. No hourly billing, no surprise invoices. The price we quote is the price you pay. Period.
Yes, 100%. Every line of code, every design asset, every piece of documentation belongs to you from day one. We provide full source code access throughout the project.
We are stack-agnostic and choose the best tools for your project. Common choices include React, Next.js, Node.js, Python, Flutter, and AWS/GCP infrastructure. We recommend the right fit during discovery.
You get a dedicated project channel (Slack or Teams), weekly sprint demos, and direct access to your development team. No account managers playing telephone. You talk to the people building your product.
Scope changes happen. We handle them through a transparent change-order process. You will see the impact on timeline and cost before approving any changes. No surprises.
We offer flexible support packages including bug fixes, feature additions, and infrastructure monitoring. Many clients keep us on retainer for ongoing development after launch.
We are a focused team of senior engineers with 10+ years of average experience. We stay lean so every client gets senior-level attention, not junior developers learning on your dime.
