Services
SaaS platform development
Multi-tenant products built to be sold, not just used. Tenant isolation, subscriptions, roles and billing are designed in week one — not retrofitted when your second customer complains.
A SaaS is not "an app with logins"
Most failed SaaS projects fail the same way: they were built as a single-client application and then patched to serve many. It works for the first customer. It breaks somewhere around the fifth — usually on a day when someone from Company A sees a record belonging to Company B.
Four decisions have to be made before the first line of code, and reversing any of them later is expensive:
- Tenancy model
- Shared database with row-level isolation, separate schemas or separate databases. This determines your cost per customer, your ability to onboard in minutes, and whether an enterprise client can ever demand their own instance.
- Data isolation
- Enforced at the database layer, not by a filter someone might forget to apply in a query written eight months from now.
- Roles and permissions
- Who inside each customer's organization can see and do what, and how that stays manageable when one client has three users and another has three hundred.
- Billing
- Plans, limits, trials, upgrades, downgrades, failed payments, prorating. This is the part founders consistently underestimate, and it's the part that touches every other part of the system.
We design all four in the architecture stage, in writing, before building anything.
What we build
SaaS from zero
From validated idea to a product with paying customers: architecture, application, admin panel, onboarding, billing and deployment.
MVP for validation
A deliberately narrow first version, built on an architecture that can grow. Small scope, correct foundations — the opposite of the throwaway prototype that has to be rebuilt the moment it works.
Turning internal software into a product
You built something for your own company and clients started asking for it. That's a real business, and it's also a rebuild: multi-tenancy, billing and isolation weren't there before. We've mapped this path and can tell you what it costs before you commit.
Scaling an existing SaaS
Performance, cost per tenant, migration to a different tenancy model, or the enterprise requirements your first big client is about to put in front of you.
What we build it with
Next.js, React and TypeScript on the front end; Node.js, PHP or Laravel on the back end depending on what the product needs; PostgreSQL with Prisma for data and tenant isolation; REST and GraphQL APIs for whatever has to connect.
Billing runs on Stripe or PayPal, with subscription logic, plan limits and payment states handled inside the application rather than left to the gateway's defaults. For products selling into Chile we also work with Transbank Webpay Plus, with idempotency and reconciliation — the part a gateway integration usually skips.
Infrastructure on AWS with Docker, Nginx, Cloudflare and CI/CD — so deploying a fix doesn't require anyone to be awake.
How we work
- 01
Discovery
We map what the system has to do, who uses it and what it connects to. You leave this stage with a written technical plan, a scope and a fixed number, whether or not you continue with us.
- 02
Architecture
Data model, integrations, permissions and — for SaaS — the tenancy and billing model. The decisions that are expensive to reverse get made here, on paper, before anyone writes code.
- 03
Build
Two-week sprints with a working environment you can open and click through at the end of each one. Direct access to the engineer writing the code, not to an account manager relaying messages.
- 04
Launch and support
Deployment, documentation and handover of everything: repositories, servers, accounts. Then a support agreement if you want one, or a clean goodbye if you don't. Your project shouldn't depend on us being available.
Frequently asked questions
How long until we can charge our first customer?
A SaaS with billing and multi-tenancy typically runs 3 to 6 months; a deliberately narrow MVP lands at the short end of that. The variable is almost never the technology — it's how clearly the scope is defined going in.
Can we start small and grow?
That's the recommended path, and it's different from starting badly. Small scope on correct architecture grows. Large scope on wrong architecture gets rewritten.
Who owns the product?
You do. Code, repositories, infrastructure and accounts, from day one.
Can you take over a SaaS someone else built?
Yes. It starts with a technical audit: what's salvageable, what has to be rewritten, what it costs.
Do you take equity instead of payment?
No. We're an engineering studio, not an investor, and mixing the two tends to end badly for both sides.
