Your product.
Live in 6 weeks.

We're a two-person product studio that takes your idea from concept to paying users in 4–8 weeks. Design, engineering, and AI — built by senior engineers, not outsourced juniors.

Projects start at €5K.

The real problem

Most agencies burn your budget and ghost you with a half-finished MVP.

Missed deadlines. Template designs. Devs still learning your stack on your dime. And when you finally launch? It's mid.

We don't do mid. We're two senior engineers who build with you, not for you. The kind of glow-up your product actually deserves.

What we do

Two ways to work with us.

Fixed scope. Fixed price. You know exactly what you get before we write a single line of code.

The Product Sprint

From zero to live product

You have a validated idea but no product. In 4–8 weeks, you'll have a designed, engineered, and deployed product with real users — not a prototype collecting dust.

What's included

Product strategy & technical architecture
Full UI/UX design in Figma
Frontend + backend engineering
AI integration (voice, agents, automation)
CI/CD pipeline & production deployment
30 days post-launch support
100% code ownership — no lock-in, ever

What this replaces

Hiring in-house: €150K+/year, 6 months to onboard
Traditional agency: €80–150K, 4–6 months, mostly juniors
Freelancer roulette: unpredictable quality and timelines

The Glow-Up Sprint

Your product, but better

Your product exists but it's not hitting right. We audit, redesign, and re-engineer what matters — so it performs like it should and looks like it deserves.

What's included

Full code & architecture audit
Design & UX overhaul
Performance & code quality upgrades
AI workflows & agents integrated
Migration & refactoring where needed
30 days post-launch support
100% code ownership — no lock-in, ever

What this replaces

Endless internal refactoring sprints that never ship
Band-aid fixes from contractors who don't own the outcome
"We'll get to it next quarter" — you won't

Scope defined before code starts. Every deliverable, milestone, and cost agreed upfront. No scope creep, no surprise invoices, no "that'll be extra."

What we've shipped

We build our own products. Here's what shipped.

Before we build yours, we built ours. Two products — designed, engineered, and shipped by the same team.

SaaS · Live at rezeptiona.ai

An AI receptionist that turns missed calls into booked jobs.

How it works

From idea to live product in 4–8 weeks.

Fixed scope. Fixed timeline. No scope creep, no surprise invoices.

01

Discovery Call

30 min

We learn about your product and goals. No pitch decks, no pressure — just a real conversation.

02

Strategy & Blueprint

Week 0

Problem definition, user flows, feature prioritization, and technical architecture. We leave with a clear plan.

03

Design & Build

Week 1–6

UI/UX design, full-stack engineering, AI integration — built in focused sprints. You see progress weekly.

04

Launch & Support

Week 6–8

Deployed and production-ready with CI/CD, monitoring, and 30 days of post-launch support included.

Who are we

A married couple that builds software together.

That's not just a fun fact — it's a structural advantage. Zero communication overhead between design and engineering. No handoffs lost in translation. No layers between you and the people building your product.

Not a big agency. Not a random freelancer from Upwork. We're Leander and Miraya — two senior engineers who happen to be married. One writes the code, one designs the experience. We've shipped products for some of Germany's biggest tech companies. Now we help founders ship the product they've been sitting on — in weeks, not quarters.

Leander
Leander
Senior Fullstack & AI Engineer

TypeScript, React, Node.js, Python, AWS/Azure/GCP. Production AI systems, real-time apps, infrastructure for millions of users.

Miraya
Miraya
Design Engineer

UI/UX, React, creative coding, motion design. Turns complex products into interfaces people actually enjoy using. Self-taught. Built different.

Compliance & Security

We build for your legal requirements.

Every product has compliance requirements. We don't bolt them on at the end — they're part of the architecture from the first line of code.

Built for your legal requirements

GDPR, HIPAA, SOC 2, or industry-specific — we build compliance into the architecture, not as an afterthought. Your rules, your jurisdiction.

Privacy by design

Consent flows, data processing records, and TOMs baked in from day one. We handle the technical side so you pass audits.

AI-ready compliance

LLM integrations with full compliance guardrails — data processing agreements, risk classification, and documentation for EU AI Act or your framework of choice.

Enterprise-grade security

Encryption at rest and in transit, role-based access, audit logs. Built to pass security reviews.

Common questions

We've got answers.

We work on fixed-scope sprints — you know the exact price before we write a single line of code. Most projects begin at €5,000+, depending on complexity and timeline. We scope everything together on a free intro call so there are no surprises, no hidden fees. You get a clear breakdown of deliverables, milestones, and cost before you commit.

Our core stack is TypeScript, React/Next.js, Node.js, and Python — deployed on AWS, Azure, or GCP depending on your needs. We also work with PostgreSQL, Redis, Docker, and Terraform for infrastructure. We don't chase trends — we pick what's battle-tested and right for your product. If you already have a stack, we adapt to it.

You do. 100%. Every line of code, every design asset, every deployment config — it's all yours from day one. No lock-in, no licensing fees, no strings attached. We hand over the full repo with documentation, and you can take it anywhere. It's your product, and we build it that way.

Every project includes 30 days of post-launch support — bug fixes, performance tuning, small adjustments, and monitoring. After that, we offer flexible retainer plans for ongoing maintenance, feature work, or monthly check-ins. Or you take it from here — we make sure your team has everything they need for a smooth handoff.

Absolutely. That's our "Glow Up" service — we audit your existing codebase, identify bottlenecks and tech debt, then improve the architecture, performance, and code quality. We've rescued projects from spaghetti code, outdated dependencies, and scaling nightmares. You don't always need to start from scratch.

We'll tell you on the first call. No hard sell, ever. If your project isn't something we can deliver on at the highest level, we'll say so honestly — and point you in the right direction. We'd rather turn down work than deliver something mid.

Still have questions? Reach out directly — we reply personally. Send us an email or book a free call.
