Sync up

We start with a deep-dive call to map your vision, users, and constraints. No templates — every engagement starts from zero.

Shape it

High-fidelity Figma prototypes. We iterate until it feels right before a single line of production code is written.

Rapid development cycles with daily updates. We deploy early and often — you see real progress, not slide decks.

Common
questions

It depends on scope, but a focused MVP typically takes 4–8 weeks. We move fast because we work lean — small team, direct communication, no approval chains.

Both. We've built from zero-to-one with founders who had nothing but an idea, and we've scaled mature platforms with hundreds of thousands of users. The common thread is clear goals and trust.

We build web apps (Next.js) and native mobile apps (React Native / Expo) that share as much logic as possible. One team, one codebase philosophy — it cuts cost and keeps things in sync.

Yes. We've inherited several codebases. We start with an audit, document what we find, and give you an honest assessment before committing to anything.

We work on fixed-scope engagements or a monthly retainer, depending on what fits your project. We're transparent about pricing upfront — no surprise invoices.

We're based in Zagreb, Croatia (CET timezone). We work fully async and remote by default, though we're happy to meet in person for strategy sessions if you're nearby.

Yes — we offer ongoing retainers covering monitoring, bug fixes, performance optimization, and new feature development. Many clients stay with us long after launch.
