Custom-Built Web Apps and SaaS
Custom web systems, dashboards and SaaS platforms for companies across Brazil and Europe. Scalable architecture, clean code and a focus on results.
Web systems and SaaS platforms are continuous products — not projects with a beginning, middle and end. That’s why, more than delivering code, we deliver a solid foundation that evolves with your business.
MVP in weeks, not months
FDGE builds MVPs (Minimum Viable Products) in 6 to 10 weeks, focused on what matters: validating the business hypothesis with the minimum viable functionality. No over-engineering, no ghost features. Just the essential, done well.
Architecture that scales
For systems that will grow, we think architecture from the start: properly modelled database, versioned APIs, robust authentication, async queues and jobs, automated CI/CD and observability with logs, metrics and alerts.
Modern stack
We work with Next.js, Node.js, TypeScript, PostgreSQL and modern tools like Prisma, Drizzle, tRPC and Tailwind CSS. A popular stack with an active community and easy talent recruitment — you’re not locked into obscure technology.
Who we work with
Companies that need to automate internal processes, B2B portals, niche SaaS tools or product MVPs for fast validation. We serve clients in Brazil, Portugal and the wider EU.
Frequently asked questions
How much does building a SaaS cost?
It depends heavily on scope. An MVP typically starts at around €5,000 / R$ 25,000, while more robust platforms range from €12,000 to €40,000+. After a discovery call we send a detailed proposal.
How long does the system take to build?
MVPs are typically delivered in 6 to 10 weeks. Full platforms take 3 to 6 months, with iterative deliveries so you can validate features as we build.
Do you handle ongoing maintenance?
Yes. We offer monthly retainer contracts for maintenance and evolution so the product keeps growing with new features, fixes and performance improvements.
Do I own the code?
Yes. All source code is yours, hosted in your own repository (GitHub, GitLab or other). You have complete ownership and independence.
