Product Design Agency
From a four-person startup studio to a 60+ talent team designing across industries and continents
Phenomenon Studio began with late nights on Upwork, often chasing projects until 3 - 4 a.m. First clients came - and stayed. The work scaled. So did the team. What’s never changed: high standards, deep thinking, and a shared drive to do things right.

WHAT GROUNDED US THEN, AND STILL DOES
It wasn’t one client or one breakthrough: just consistent work, good people, and a clear sense of what matters

In the founders’ words

Our company was founded in 2019 by Valerii Filimonov and Polina Chebanova, both with a background in product design but different perspectives.
Valerii came from e-commerce and early-stage startups, driven by systems thinking and user flows. Polina led cross-functional teams at design studios in Ukraine and the UK, refining how interfaces look, feel, and behave.

I saw that for many designers, beauty mattered more than logic. I wanted to create something grounded—with people who think deeply.

We started working with our first few startups on products they needed to bring to market quickly. Many of those early clients are still with us today, as we’ve grown side by side and watched each other evolve.
Step by step, these first projects turned into long-term collaborations, and today our portfolio spans hundreds of products for companies around the world.

WHAT MAKES US DIFFERENT
We’ve built hundreds of products by focusing on the right things. Here’s what our clients value most
01
Partners, not vendors
We don’t disappear after a kickoff call or pass work down a chain. You’ll work directly with the team building your product: in Slack, in Figma, and in your workflow.
02
Design that holds up over time
We build thoughtful, system-based interfaces, not flashy one-offs. Our work adapts to your product, keeps logic intact, and holds up to change.
03
Developer-ready by default
Every component is reusable, accessible, and engineered for handoff. Tokens, states, constraints—we speak dev and design like we code. That’s how we ship fast.
04
Process you can follow
You see what we see. From day one, we make progress visible in Notion, Jira, Figma, or your stack. Scope, estimates, and feedback loops stay open and honest.
05
Product-led design thinking
We work at the intersection of design and business. From product-market fit to scale-readiness, our designers think like product managers, aligning UX with growth metrics, not just user flow.
06
People who care about the work
Our edge isn’t tools or templates—it’s the people. Curious, invested, and obsessive about doing the right thing right. You’ll feel it in the work and in every interaction.
OUR TEAM
Meet the phenomenal people behind our projects
We believe great work doesn’t come from titles; it comes from people. Ours think deeply, care fiercely, and take pride in what they build. From product leads and designers to developers and advisors, we work across time zones and disciplines but share the same core: curiosity, honesty, and a hands-on commitment to doing things right.

Founder & General Partner, Predictive

Phenomenon Studio's ability to translate concepts and rough design mock-ups into high-fidelity assets, designs, and visuals was very impressive. The goal was to maintain simple elegance in the design aesthetic, and they did it very well.

WHAT IF YOU HIRE PHENOMENON
Diving deeper into what we can bring to your table
If you’re curious to see the thinking, processes, and hands-on delivery that power our work, here’s where to start:
Services

From investor-ready MVPs and product design systems to full dev team extensions, we help tech companies build things that work and last. Whether you need UX strategy, interface design, or ongoing product delivery, you’ll work with a focused team that embeds fast, adapts to your stack, and delivers without dragging timelines.

Cases

We design and build products across FinTech, EdTech, Healthcare, Web3, and SaaS. From mobile apps and dashboards to branded websites and internal platforms, our work covers real user needs at every product stage. Whether it’s shaping flows from scratch or delivering clean UI kits for development, we focus on clarity, usability, and results that make sense.

Prices

Every product and company are different, but pricing shouldn’t feel like a black box. We offer transparent estimates for every stage of building a product: design, development, research, and strategy. Whether launching an app, building an MVP, or redesigning a platform, you’ll see the scope, service, and delivery details clearly laid out.
