The prototype that can't grow up
You paid for an MVP and got a demo — brittle code that breaks the moment real users, real data and a second customer show up. Scaling it means starting over.
SAAS DEVELOPMENT
SaaS Development Company — MVP to Scalable Platform
You need a SaaS platform, not a website. We build the product itself — architecture, billing, multi-tenancy and all — so it holds up when users actually arrive.

Most agencies build you a landing page and call it a product. A SaaS platform is a different animal: subscriptions, tenant isolation, user roles, an API others depend on, and an architecture that survives its own growth. That is what we build. Ostohlo is a product web studio — we ship systems, not pages.
If you are a founder or CTO scoping your first release, start with the smallest thing that proves the model, then harden it. Our guide to building a SaaS web application walks through the decisions that decide whether v2 costs you a full rewrite. This page is the short version — and an invitation to build with a team that has shipped its own SaaS.
(01)
What usually goes wrong
No real multi-tenancy
Onboarding your tenth customer takes manual work because data isolation, roles and limits were never designed in. Every new account is a risk instead of a click.
Billing bolted on as an afterthought
Trials, upgrades, proration and failed payments were an afterthought, so revenue leaks and every plan change is a support ticket and a bug report.
An agency that hands off and vanishes
The team that built it thought in deliverables, not products. There is no architecture to reason about, no docs, and no one who understands the code you now own.

What we build
MVP development
We cut your idea to its load-bearing core and ship a real, usable product in weeks — not a throwaway prototype. The MVP is the first version of the platform, not a demo you replace.
Multi-tenant architecture
One codebase, isolated data per customer. We design tenant boundaries, roles and quotas from day one, so onboarding your hundredth account is a click, not a re-architecture.
Billing & subscriptions
Plans, trials, upgrades, proration, dunning and invoices. We wire Stripe or your gateway into a billing model that matches how you actually charge — and keep it auditable.
Dashboards & user roles
The admin panel and customer console where your product lives. Granular permissions, team seats, activity logs and the data views your users need to trust the tool.
Integrations & API
A documented REST or GraphQL API, webhooks, and the third-party connections — payments, email, analytics, auth — that make your SaaS part of a workflow instead of an island.
Scalable architecture
Clean service boundaries, background jobs, caching and a database schema that holds under load. We build for the traffic you want, without over-engineering for traffic you do not have yet.

Products already in production
We are not describing work we have only done for other people. Ostohlo runs its own SaaS products. Urlik is our link-management platform — accounts, dashboards, an API and the billing plumbing a real SaaS needs. 24freelance is a full freelance marketplace: multi-sided accounts, roles, transactions and moderation at scale. We ship the same systems we sell, which is why our estimates and our architecture advice are grounded in production, not slides.

How we work
01
Discovery first
Before a line of code, we map the jobs your users hire the product for, the data model, and the risky assumptions. You leave with a scoped MVP and a clear v1 boundary — not a vague estimate.
02
Smallest provable version
We ruthlessly cut v1 to what proves the business and stage everything else. A few features shipped well beat a broad roadmap half-built and unstable.
03
A stack that fits
We pick a proven, boring stack matched to your product and team, so you can hire for it and we can move fast. No framework-of-the-month, no lock-in to novelty.
04
Architected for v2
We make the decisions early that are expensive to change late: tenancy, auth, the data model, the API contract. The MVP is small; the foundation under it is not.

Why Ostohlo
- Product mindset, not project mindset — we optimise for a platform that lives and grows, not a deliverable we hand off and forget.
- We run our own SaaS ecosystem — Urlik and 24freelance are live products we operate, so we know where SaaS breaks in production.
- A senior team — you work directly with the people writing the architecture and the code, not an account manager relaying to juniors.
- Transparent process — scoped phases, honest estimates and no invented urgency; you always know what is shipping and why.
- You own the code — full source, infrastructure and accounts are yours from day one, with no lock-in to us.

FAQ
Serious SaaS work starts around $20k for a scoped MVP and rises with tenancy, billing and integration complexity. We quote per scope after discovery, never by guesswork. See our services for how we package engagements.
A focused MVP typically ships in a couple of months, depending on surface area. We stage the build so you have something demoable and testable well before the full v1.
Proven, maintainable stacks matched to your product — usually a modern PHP or Node backend, a React front end, PostgreSQL, and Stripe for billing. We choose for hireability and longevity, not novelty.
Yes. We audit what you have, document the risks, and give you an honest call on refactor-versus-rebuild before touching anything. Sometimes the right answer is to keep it and harden it.
Yes — plans, trials, upgrades, proration, invoices and failed-payment handling, integrated with Stripe or your gateway of choice and modelled to match how you actually price.
Completely. Repositories, servers and third-party accounts are in your name from the start. There is no lock-in and nothing held hostage — you can walk with everything at any time.
