The founder
I built a language app because I was the customer nobody served.
I am an engineer who hit the language ceiling in a real job.
Dominik Moelsen · Engineer & Language Learner · Beijing

Worked at an R&D office in Beijing, learned Mandarin for a few semesters at Tsinghua. On paper my Mandarin was HSK 5. In the room, I went quiet.
Most apps I tried stopped at intermediate or went a wrong direction. Tutors teach the average of every job, but that is nobody’s job. What I needed was a program built for my actual work: the vocabulary of my niche, the situations I was failing in.
So I built the program I needed — then built it for the language most people in Europe actually get stuck in at work: English.
Certified is not usable.
nicheAce: language starts with a conversation about your job and what your current proficiency is, then turns that into a 15-week journey. Five learning days a week, five exercises a day, fifteen minutes each. Language learning needs the effort, it is not “5 minutes a day to fluency” and definitely not to workplace confidence.
While people in Europe are exceptional in learning and speaking languages in daily conversations, many lack real workplace knowledge and confidence. Fluency is no longer enough.
nicheAce: language is made for getting workplace confidence.
One person, by design.
nicheAce is a one-person company. That is a design decision, not a stage.
A mass-market language app needs millions of users to break even. We need a few hundred subscribers. That single fact decides everything else: which niches we can afford to serve (small ones, deep ones), how fast we can change the program (overnight), and what we never have to do (raise money to chase scale we do not want).
I write the code, answer the support mail, and use the product every day. If I hired a team, I would become the incumbent I built this to avoid.
The trade-off is real: I will never move as fast on ten fronts as a funded team. So we move on one: the finish line for one professional niche at a time.

If you want a product built by someone who is also the customer, this is what that looks like.
