Potca Digital: Humane digital products

digital
Research and product thinking for humane digital tools.
Research-led digital products

Potca Digital builds digital products shaped by research, product thinking, and care for how people actually use technology.

Potka is the thread that binds the whole

In weaving, the potka (weft) is the horizontal thread that runs through the warp. It is rarely the loudest element on the loom — yet thanks to it, everything holds together.

Coding and weaving do the same thing: they connect small elements into meaningful products for people. We treat products as systems that help people do something more clearly, calmly, or independently.

How we work

01
Always with the user in mind
Technology is here because of people, so we invest heavily in user testing.
02
Research matters
We test hypotheses. We pilot, validate, iterate before we scale.
03
Privacy at the heart of design
We collect only what returns value to the user.
04
Thoughtful design
Simple is not shallow. Much of our work is removing unnecessary complexity.
05
Small steps
Big change usually starts with one small, well-placed step.

What we build

Potca Digital is a small independent digital studio for products that need research, testing, and sharper decisions before they grow. We begin with research, clear thinking and working prototypes, then shape technology around the human problem instead of making people adapt to the tool.

Our focus is humane software for attention, learning and everyday support. That means calm interfaces, privacy by default, and product decisions that can be explained without jargon. We care about what a product asks from a person, not only what it can technically do.

Potca Digital is a young company, but with a clear direction: build fewer things with more attention. We document assumptions, test the riskiest parts first, and build new releases with results in mind. Every release therefore has a simple question: does the change make using the product easier for the person? If the answer is not yet clear, the product stays small while we learn. That keeps the work grounded in evidence, not wishful thinking.

01

We turn research into products

Interviews, observations and domain knowledge become decisions people can actually use.

02

Privacy-respecting tools

We avoid attention traps, unnecessary data collection and growth tricks that make the product worse.

03

Small tested releases

We prefer pilots, feedback loops and careful iteration before a product becomes louder or larger.

Goblinaut
For chaotic brains · ages 6–16

An app for children and young people with attention difficulties

Goblinaut turns hard tasks into tiny missions. It's a companion that's just there, offering help for hard moments, support instead of lectures. No ads, no tracking.

Goblinaut grew from real family routines: the small daily moments when children need support starting, switching, or finishing a task.

Founders

Founded by people who understand products and how ideas get built.

Potca is led by Sanja Radić and Mia Biberović, two founders with different but complementary instincts for turning early ideas into products people can actually use.

Sanja Radić

Sanja Radić

Co-founder · Innovation & business strategy

Sanja works at the intersection of technology, innovation, and business development. She brings 14 years of experience: seven in IT and digital solutions, and seven advising startups and established companies on business models and go-to-market. At Potca Digital, she leads innovation strategy, business modelling, and the path from early concept to market.

Mia Biberović

Mia Biberović

Co-founder · Product, media & startup insight

Mia works where product thinking meets media, users, and technology communities. Years of observing startups and digital products from close range shaped her understanding of how ideas survive contact with real people, and led her to start building a product of her own. At Potca Digital, she leads product direction, user research, communication, and the decisions that turn early ideas into useful digital products.

Together

Potca exists for early ideas that need both structure and product sense: what should this become, who is it for, how can it be funded, and what needs to be built first.
