Client
So tell me, what exactly do you do for clients like me?
I build websites. Uh, mostly for, uh, small businesses.
Filler words detected: "uh" x2
Client
Our audience is investors. Does this actually work for B2B?

The real problem

Your skills got you the meeting.
Your English decides what happens next.

You understand English. You read it every day. But speaking it live, while a client waits, is a different skill. And nobody teaches that.

You know your work

You can build the website, edit the video, run the ads. That was never the weak part.

Speaking live is hard

The answer is in your head. But it comes out slow, or full of "uh", or not at all.

Clients decide fast

A few seconds of silence, and they stop trusting you. Even when your work is better.

That is why Fluenstra exists. To practice this before it costs you a client.

How it works

Three steps. One month.

Not a course. Not videos you watch alone. Real practice, real feedback, and a real teacher at the end.

1

Practice with AI

Talk out loud to an AI client that pushes back, asks hard questions, and does not wait politely while you think.

Up to 12 calls a month
2

Get your call report

After every call you see what you did well and what to fix, taken only from what you actually said.

After every call
3

Learn from a real teacher

Meet a native English teacher from the US or UK. Your reports are already in their hands before you join.

2 live sessions
Your call report

Every practice call becomes your learning plan.

No general English score. The report only looks at how you handled this client, in this conversation.

  • Built from your own words. Not a generic test.
  • Shows the exact moment the call went wrong, and a stronger answer you could have used.
  • You can try that answer again and see your score move.
  • Your teacher gets the same report before your live session.

Client asked if your work fits B2B. You answered with a promise, not proof.

Stronger answer: "Fair question. I worked with a finance firm last year. In 60 days their site brought in 12 qualified leads."

Answering price questions without saying sorry first.

Your native teacher

Your teacher already knows where you need help.

This is the part that changes everything. Your practice reports are shared with your teacher before your live session.

  • No starting from zero. You never explain your level again.
  • No wasted minutes. The session starts on your real weak point.
  • Native teachers from the United States and the United Kingdom.
  • The AI prepares you. The teacher changes you.
Meet the teachers

Real people. Real client experience.

Every teacher has worked with international clients themselves. They know the call you are about to walk into.

Built for freelancers

Find your work. See the call you will practise.

Every kind of freelancer loses clients differently. Your practice matches the calls you actually get.

🎨

Designers

Your callThe client says your design is "not what they imagined". You defend your choices without sounding defensive.
💻

Developers

Your callYou explain why the timeline is 6 weeks, not 2, in words a non technical buyer understands.
📈

Marketers

Your callThe client asks what results you can promise. You answer honestly and still sound confident.
✍️

Writers

Your callThey want unlimited revisions for the same price. You hold your scope politely.
🎬

Video Editors

Your callThe client keeps adding "small changes". You explain what is extra work, without losing them.
📱

Social Media Managers

Your callThey ask why followers did not grow this month. You lead the conversation instead of apologising.
📊

Virtual Assistants

Your callA first interview call. You describe everything you can handle, clearly and fast.
🚀

Practice scenarios

Pick the situation. The AI client behaves the way that kind of client really behaves.

Discovery call

First meeting. Explain what you do, clearly and fast.

Price discussion

They say it is too expensive. Hold your number.

Portfolio presentation

Walk through your work without reading a script.

Agency interview

Answer fast questions from a hiring manager.

Project update

Report progress, and explain a delay honestly.

Negotiation

Ask for more scope, more time, or more money.

Difficult client

Client meeting

A normal weekly call. Small talk included.

The difference

The same call. Two different people.

Nothing changes about your skills. Everything changes about how you walk in.

😰Without Fluenstra
  • Nervous before the call even starts
  • Filler words: "uh", "um", long silences
  • No practice, ever
  • The real client call is your first try
  • They say no, and you never learn why
😊With Fluenstra
  • Calm, because you have done this call before
  • Filler words caught and reduced
  • 12 practice calls behind you
  • A native teacher already fixed your weak points
  • You know exactly what to say next time
Designed for real conversations

Not a quiz. A conversation that fights back.

Real clients do not wait politely while you find the word. Neither does your practice.

Real interruptions

They cut in mid sentence. You learn to hold your ground and finish your point.

Real negotiations

"That is too expensive." You practise holding your price without apologising for it.

Real difficult questions

"Have you done this before?" You answer with proof, not a promise.

Real client personalities

Impatient, friendly, sceptical, silent. Each one changes how you have to speak.

From freelancers like you

They were never bad at their work.

Questions

Things freelancers ask us first.

My English is not very good. Is this too early for me?
No. If you can read this page, you can start. The AI client speaks clearly and waits for you. Most people are nervous on their first call and much calmer by the fourth.
Do I really speak out loud, or is it typing?
You speak. Out loud, with your voice, like a real call. That is the whole point. Typing practice does not help you when a client is waiting for an answer.
Who are the teachers?
Native English teachers from the United States and the United Kingdom. They read your practice reports before your session, so they know your weak points before you say a word.
What if I miss a month of practice calls?
Nothing is lost. Your reports and progress history stay in your account. You continue from where you stopped.
Will this fix my accent?
We do not try to remove your accent. Clients do not need you to sound American. They need to understand you, and they need you to sound sure of yourself.
Can I cancel?
Any time, from your account. No contract, no cancellation call, no questions.
