Multi-tenant architecture done right
Each customer's data isolated and secure, minimal infrastructure cost per customer, and new-tenant onboarding in seconds — not days of configuration.
We build SaaS products from scratch or scale existing ones: multi-tenant architecture, subscriptions and automated billing, dashboards, public APIs, and enterprise-grade security. The same team that shipped working fintech platforms and marketplaces.
from €4500
SaaS means software running for hundreds of customers simultaneously — the wrong architecture gets expensive at scale.
Each customer's data isolated and secure, minimal infrastructure cost per customer, and new-tenant onboarding in seconds — not days of configuration.
Complete Stripe integration: plans, trials, prorated upgrades/downgrades, automatic invoices, and failed-payment recovery — your revenue machine on autopilot.
SSO/SAML for enterprise customers, granular roles and permissions, audit logs, encryption, and GDPR compliance — the security-questionnaire requirements that block B2B deals.
MRR, churn, LTV, cohort activation — the metrics dashboard investors (and you) demand, built directly into the product.
In-app assistants, intelligent data processing, auto-generated reports — we integrate OpenAI, Claude, and Gemini as your product's competitive edge.
A documented REST API, webhooks, and integrations with the tools your customers already use (Slack, Zapier, CRMs) — the #1 reason B2B customers stay.
We define the target segment, pricing model, and differentiating features. The result: specification, architecture, and a fixed budget.
We launch the core: authentication, main functionality, subscriptions, and onboarding. Your first paying customers validate the direction.
We analyze activation and churn, prioritize the backlog together, and ship what moves the metrics in 2-week sprints.
We add SSO, a public API, audit logs, and performance optimization as you move upmarket to bigger customers and serious volume.
From first paying customer to mature product — the investment grows only with validation.
The product core with working subscriptions — ready to charge your first customers.
A complete growth-stage product: teams, permissions, integrations, and advanced metrics.
Ready for big customers: SSO, audit, performance SLAs, and advanced security.
Every package includes a free consultation, a contract, and post-launch support.
How much does it cost to build a SaaS? A SaaS MVP with working subscriptions — €4500, a growth-stage product with teams, API, and integrations — €9000, and an enterprise version with SSO and audit logs — €15000. These numbers are possible because we don't reinvent the wheel: we use the same proven foundation (Next.js, TypeScript, PostgreSQL, Stripe) and build your product's differentiators on top.
The expensive SaaS mistake is "temporary" single-tenant architecture: it works with 5 customers, but at 50 it becomes a maintenance and cloud-cost nightmare. We build multi-tenant from the start — data isolation, per-organization billing, and automated onboarding are the foundation, not "future improvements". Same with metrics: MRR, churn, and activation are measured from day one, because you can't optimize what you can't see.
Where should you start? If the idea isn't validated yet, start with a focused MVP and move to full SaaS after your first paying customers. If you already have a growing product, our team can take over development as a dedicated team or add AI features that set you apart.

A SaaS MVP with subscriptions — €4500. A growth-stage product with organizations, API, and integrations — €9000. An enterprise version with SSO and audit logs — €15000. All with a fixed price in the contract, set after a free product discovery.
The SaaS MVP with working payments is ready in 8 weeks. That includes authentication, core functionality, Stripe subscriptions, and onboarding — everything needed for your first customer to pay and use the product.
One application instance serves all customers, with data fully isolated between them. It matters for costs (infrastructure is shared), onboarding speed (a new tenant in seconds), and maintenance (one deploy for everyone). The alternative — separate instances per customer — becomes unsustainable as you grow.
Through Stripe: multiple plans, trial periods, prorated upgrades/downgrades, automatic invoices, EU VAT handling, and failed-payment recovery. You run a subscription business without manual billing work.
Yes. We start with a technical audit (architecture, security, scalability, cloud costs) and you receive a report with honest options: continue on the existing base or rebuild the problematic components. Then we take over development with a dedicated team or sprint-based work.
Yes — the marketing landing with pricing, blog, and SEO is part of the Growth and Enterprise packages, built on the same fast foundation. A good product also needs a customer-acquisition machine.
