How We Can Help
Idea → Product
1
You have the idea, but not yet the product. We help define the MVP, structure the experience, and turn the idea into something clear enough to build.
Logo Design
Visual Identity Systems
Brand Guidelines
Typography & Color Systems
Naming & Tone of Voice
Brand Strategy
AI-Built → Refined
2
You built an app with Lovable, Claude Code, Codex, or another AI tool. It works, but the design feels generic and the user experience needs attention. We turn your AI-built app into a polished, intuitive product.
Web Design
App & Interface Design
UX/UI Design
Design Systems
Responsive Design
Product Redesign
3
Your app is live, but the experience isn’t meeting expectations. We rethink the structure, simplify complex workflows, and redesign the interface to make your product easier to use.
Creative Direction
Campaign Design
Visual Storytelling
Motion & Animation Guidance
UX Improvements
4
Not every app needs a complete redesign. Sometimes the problem is onboarding, navigation, or a specific user flow. We identify what’s causing friction and focus on fixing what matters most.

Founder of SWTCH

I get screwed by another company and almost quit my idea of creating an app. I held multiple interviews with people and chose Ivan. I'm so glad I did. Within a few days he and I talked a bunch to create the app I was dreaming of. He's extremely detailed and wants to make sure you enjoy every part of the app. I am moving on to the development phase with him and his partnering team. Please choose him for your app, you won't regret it

We had an incredible experience working with GRONA and his team. We took a bit of a risk signing the contract with them without a referral but we are so glad we did. They're incredibly professional, responsive, and talented

FAQs
Very early. You don’t need a finished brief, wireframes, or even a prototype. If you have a strong product idea and are starting to think seriously about what to build, that’s enough to begin the conversation. In fact, the earlier the important decisions are still flexible, the more useful we can be.
Our core services include brand identity, digital design, art direction, and strategy. We often work across multiple touchpoints to ensure consistency and cohesion in everything we create.
Yes. A fast prototype is useful because it makes the idea tangible. But it can also lock in decisions that were never properly considered. We use what you’ve created as a starting point, then step back and ask what the product actually needs before turning it into something ready for development.
No. If we think a feature is unnecessary, a flow is too complicated, or there’s a stronger way to solve the problem, we’ll tell you. We’re not hired to execute decisions blindly. We’re hired to help make better ones.
You’ll be involved where your input matters most: product decisions and key checkpoints. We start by understanding the product with you, then handle the design process and bring you in when decisions or feedback are needed. Most communication can happen asynchronously.
A full mobile product engagement typically takes around 3–4 weeks. You’ll usually start seeing product direction and recommendations within the first few days. Exact timing depends on product complexity, scope, and feedback.
A clearly defined, development-ready mobile product for the agreed scope. That can include the product direction, core flows, key states and interactions, polished UI, design system, prototype, and handoff materials. We also stay available for **30 days** to answer design-related questions during implementation.
