Private Spanish coaching for entrepreneurs, executives and professionals

“I understand more than I can speak.”

If this is you, you do not need more Spanish. You need a system that turns what you already know into real conversation. That is what I build.

Book your free roadmap call Thirty minutes. You leave with a plan, whether we work together or not.

A system, not another app Built around your calendar Built around your work

If this sounds familiar

“I understand slow Spanish, but when a native starts talking I freeze.”

“I translate in my head and it kills the flow.”

“I need a system. Apps alone are not enough.”

You freeze

Your turn to speak comes, panic arrives, and nothing comes out.

You translate

You build the sentence in English first, and the conversation has moved on.

You know the word

You recognise it when you read it, but you cannot reach it when you need it.

None of this is a knowledge problem. It is a structure problem. Without a system you study on and off, you repeat the same words forever, and the Spanish stays locked in your head. With a system, the same effort turns into speech.

The structure that was missing

Spanish OS is one plan, in the right order, built around your life and your work. This is what most learners have never had, and it is why my clients get conversational 10 to 15 times faster than they did with apps, courses and random tutors.

1

Your roadmap

I map where you are and the exact situations you need Spanish for. Then you get a personal plan with the precise daily steps, in order. No more guessing what to study.

2

Daily execution

A daily plan with the exact steps, in order. Input you understand, speaking out loud, and pulling words back under pressure. You always know what to do next.

3

Coaching and feedback

Weekly one to one calls where you actually speak, plus daily video feedback. I catch the exact moment you freeze and fix it.

Kai

My father taught languages for over thirty years, so I grew up around them and ended up speaking six myself. I built Spanish OS after watching busy professionals spend years on apps and random study without ever getting a system. That gap is the whole business: one structure that fits your schedule and takes you to real conversation.

What happens when there is structure

From 1-minute phone calls to 2-hour client conversations in 2 months

Tori struggled to speak with her own clients. Two months in, she was holding 2-hour client conversations and running intake calls herself, while working full time with two kids.

From low A2 to 90-minute unscripted conversations in about 3 months

Clayton could not hold a conversation with his neighbours in Bolivia. Three months later he negotiated with a contractor, got daily compliments on his Spanish, and started getting invited to local events as a local.

From zero Spanish to airport conversations and travel talk in 4 months

Demetra started at A1. Four months later she was holding airport conversations and talking about travel in past and future tenses.

From no Spanish at all to daily life conversations in 3 months

David, an entrepreneur, went from zero to ordering food, chatting with locals and sharing his opinions while living in Colombia, studying 40 to 60 minutes a day. It was his first foreign language, ever.

From mid-A1 to handling official appointments himself

Torge went from mid-A1 to handling a civil office appointment on his own and chatting with tradespeople and vendors.

From 3 years of Duolingo and freezing to real conversations

Stephanie froze under pressure after three years on Duolingo. Then she held real-time conversations with a Colombian family and volunteered in Spanish at a food bank.

From not speaking to holding conversations in 2 months

“Kai’s Spanish OS program is amazing! I learned so much quickly. I enjoyed our structured, interactive calls which forced me to use Spanish without reaching for a translator, which is huge for me. His frameworks are great for learning fast, and I like that it’s tailored to my specific plans for using Spanish. The homework keeps the momentum going and the learning easy. Highly recommend if you want to learn Spanish quickly and for your specific needs.”

And many more.

These are their outcomes, not a promise. Results depend on your starting level, your target situations, your practice time and your consistency.

You do not need more Spanish. You need a system.
