What We Do

Full-Cycle Development,
Zero Compromise

From discovery to deployment — our cross-functional teams deliver complete software solutions with speed and precision.

How We Work

Agility-Driven.
Results-Obsessed.

Our battle-tested process gets you from kickoff to launch faster than traditional development — without cutting corners.

01

Discovery & Scoping

We run a focused discovery session to understand your goals, define the MVP, and map the product backlog. In 3–5 days, you get a full project scope, technical architecture, and sprint plan.

3–5 days
02

Sprint Zero — Setup

Environment setup, CI/CD pipeline configuration, design system establishment, and team onboarding. You're production-ready before we write the first feature.

1 week
03

Iterative Build Cycles

Two-week sprints with daily check-ins, mid-sprint demos, and continuous deployment to staging. Every sprint ends with working software you can touch and test.

2-week sprints
04

QA & Hardening

Automated test suites, performance profiling, security scanning, and manual exploratory testing. AI-assisted QA catches regressions faster than any manual process.

Continuous
05

Launch & Scale

Zero-downtime deployment, post-launch monitoring, and immediate hotfix capacity. After launch, we can continue as your long-term development partner or hand off cleanly.

Go Live

AI Accelerates Every Step

We've integrated AI tooling across our entire workflow — engineers use AI pair programming, automated code reviews, intelligent test generation, and deployment anomaly detection. The result: 40–60% faster delivery with higher code quality.

Why Joyrun

The Difference
Is In How We Work

Speed Without Sacrifice

AI tooling and refined agile processes let us deliver 2x faster than traditional teams without sacrificing code quality or architectural integrity.

IP Protection

Full IP assignment, NDAs on day one, and secure development environments. Your code, your data, your business — protected by contract and by practice.

Radical Transparency

Real-time sprint boards, weekly demos, and direct access to every engineer on your team. No account managers in the way, no surprises at the end.

Senior-Only Engineers

We don't staff projects with juniors. Every team is led by senior engineers with 5+ years in their domain — people who can make architectural decisions on the fly.

Built to Hand Off

Clean code, thorough documentation, and structured knowledge transfer. If you ever want to bring development in-house, we'll make the transition seamless.

Flexible Engagement

Fixed-scope projects, dedicated teams, staff augmentation, or retainer-based partnerships — we structure engagements around your needs, not our convenience.

Client Stories

Don't Take
Our Word for It

Real results from product teams who shipped with us.

“

I was looking for a studio that could start working quickly and take full product management off my hands. For me, as an entrepreneur, it was important to save time and energy and to be more of a product owner in the project

I collaborate with a great team, and I’m really satisfied with them. Why? First off, they provide clear and transparent numbers. We work in a micro-contract format, so you know exactly what will be done, in what timeframe, and for what cost.

When choosing a development studio, it was important for us to find a team that not only does their job professionally but also truly understands and shares our goals and vision for the product. The Along team helped develop a product for a friend of mine, and he was thrilled with their approach.

Common Questions

Before You
Reach Out

Answers to the questions we hear most from new clients.

What does a typical project cost?

Project-based engagements start from €15,000 for a focused MVP build. Dedicated team retainers start from €8,000/month for a 3-person senior team. We'll send a detailed estimate within 24 hours of receiving your project brief — no strings attached.

How quickly can you start?

We typically kick off within 5–7 business days of contract signing. Discovery and team onboarding run in parallel, so you're not paying to wait. Current availability: 2 slots open for Q2 2026.

Who owns the code and IP?

You do — always. Full IP assignment is included in every contract. We sign NDAs on day one and work exclusively in your infrastructure or a dedicated environment you control. Your code, your data, no exceptions.

Can you work alongside our in-house team?

Absolutely — staff augmentation is one of our most common models. We embed 1–3 senior engineers directly into your workflow, using your tools, your ceremonies, and your codebase. No disruption to existing processes, just immediate added capacity and expertise.

Do you work with early-stage startups or only established companies?

Both. About 40% of our projects are 0→1 builds with funded startups — we're particularly strong at taking an idea from scoping to a production MVP. The remaining 60% is with scale-ups and enterprises expanding their engineering capacity or launching new product lines.
