Our Advantage

Why We Ship Faster — Genexy

While other teams start every project from scratch, we start at 60%.

Genexy generates the entire technical backbone of your product — APIs, database layers, infrastructure, auth — in hours instead of weeks. Deterministic, tested, zero tech debt from day one.

Your budget goes toward what makes your product unique — business logic, UX, and the features your customers actually care about.

How We Work

From Your Idea to Live Product

A clear, transparent process — you stay in control, we handle the complexity.

1

You Describe Your Vision

Tell us what you want to build. We listen, ask the right questions, and turn your idea into a clear technical plan and architecture.

First call to technical plan: ~1 week

Foundation Generated in Hours

Genexy generates 50–80% of the codebase — APIs, data layers, infrastructure — deterministically, with best practices baked in. What normally takes weeks happens in hours.

Technical foundation: hours, not weeks
3

Your Product Goes Live

We implement business logic, UI, and integrations on top of the generated foundation. Testing, deployment, and handoff included.

Business logic + UI: 4–10 weeks typical

What You Get

The Results

Every project starts ahead — because the foundation is already built.

01

Launch 2–3x Faster

Your product goes live in weeks, not months — without cutting corners.

02

Zero Tech Debt from Day One

Generated code is deterministic, tested, and follows best practices. No shortcuts that haunt you later.

03

40–60% Lower Dev Cost

Less manual coding means lower cost. Your budget goes toward features, not boilerplate.

04

Change Without Rewrites

Need to pivot or scale? We regenerate the foundation instantly — no painful rewrites.

What Clients Say

Trusted by Product Teams

From transport operators to telecom and banking — teams trust us to deliver.

A complete EV charging optimization platform delivered end-to-end — custom scheduling algorithms, OCPP integration with hundreds of devices, real-time monitoring and alerting. The system has been running in production 24/7 and delivered measurable ROI within months.

Who We Work With

Is This for You?

We work with founders, CTOs, and product teams who need production-ready software but don't want to build a 10-person dev team.

Startup Founders

You have a product idea and need to get to market fast — with code that won't need to be rewritten at scale.

CTOs & Tech Leads

You need to extend your team's capacity without the overhead of hiring, onboarding, and managing more engineers.

Product Companies

You need a reliable engineering partner who thinks in products, not just tickets. Someone who cares about the outcome.

Typical Engagement

Most projects we take on are in the €15K–€80K range, with timelines of 6–16 weeks from kickoff to production.

We're a good fit if you need a production-ready product and value speed, code quality, and long-term maintainability over the cheapest possible quote.

We're probably not the right fit if you need:

  • ·A single freelancer for a few hours of work
  • ·The cheapest possible development option
  • ·A team to maintain legacy code without modernization

Common Questions

Frequently Asked Questions

Most projects go from kickoff to production in 8–16 weeks, depending on scope. Simple MVPs can ship in 4–6 weeks. Our automation platform generates the technical foundation in hours, so the majority of time is spent on business logic and UI — the parts that actually matter to your users.

We start with a discovery call to understand your product vision. Within a week, you get a technical plan and architecture proposal. Once approved, Genexy generates the foundation and we begin implementing your specific features. You get regular demos and stay in control throughout.

Yes. Our automation-first approach is especially valuable for startups because it dramatically reduces the cost and time to build an MVP. You get production-grade code from day one — not a prototype that needs to be rewritten when you scale.

We offer ongoing support and development. Because the codebase is generated with best practices and zero tech debt, it's easy to maintain and extend — whether by our team or yours. We also provide documentation and knowledge transfer.

Our proprietary platform Genexy generates 50–80% of the codebase automatically — APIs, data layers, infrastructure. This means faster delivery, lower cost, and higher quality than traditional development. We're not just writing code faster — we're eliminating the parts that shouldn't be written manually in the first place.

Absolutely. You own 100% of the code and IP. The generated code is clean, readable, and follows industry best practices. There's no vendor lock-in — you can take the codebase and continue development with any team.

We work across the full stack: Go, Java/Spring Boot, C#/.NET, Next.js, React, React Native, PostgreSQL, MongoDB, Docker, Kubernetes, and more. We choose the right tools for each project based on requirements, not preference.
