DIAL IN
The best salespeople aren't braver than you.
They just learned the one thing nobody taught you.
Take the 15-Second TestThe 15-Second Test
Write the opening line you'd use on your next cold call.
In a real cold call, you have about 15 seconds before your prospect decides to stay or hang up. Let's see what you'd actually say.
Ready? The timer starts when you click.
The truth
Let's be honest.
Cold calling feels like a burden. You stare at the phone. You rehearse in your head. You dial — and the moment someone picks up, your mind goes blank.
You're not bad at sales. You just never learned the part that actually matters.
Research shows that prospects decide within the first 15 seconds whether to stay on the line or hang up. 93% of a cold call's success comes down to how you open. Most salespeople have already lost before they even start talking.
DIAL IN covers about 20% of the entire sales process — but it's the 20% that drives 80% of your results. The fundamentals. The opening. The connection. Step by step. In a room. With real calls. No theory slides. No motivational fluff. Just what separates people who sell from people who struggle.
The silent compound interest of avoidance.
Every week you put off the phone, the math keeps running — quietly, without you noticing. Here's what that bill looks like at scale.

How we get there
“First Signal pays for itself the moment you close one deal you would have otherwise avoided. Everything after that is money you didn't have before.”
Scroll down. Fix this.
The Series
Three Workshops. One Transformation.
Each level goes deeper. The group gets smaller. The results get bigger.
All workshops are conducted in English. Participants of any native language are welcome — live call exercises can be done in any language, with best coaching support in English, German, and Polish. At least a good communication level in English is required.
First Signal
Build the connection
Your first 25 seconds on a call decide everything. Learn why most intros fail, what the five questions your opening must answer, and build a script that feels natural — not robotic. Then test it live, on real calls.
- →A battle-tested intro script you built yourself
- →Live feedback from peers and Dennis on every call
- →Why connection always comes before selling
- →Confidence that the phone is not your enemy
Strong Signal

You got through. They're listening. Now what? Learn to stay in the conversation — handle resistance, deepen trust, and guide a cold call into a real dialogue. Work in a pair with Dennis, tailored to your industry and leads.
- →Techniques to deepen the connection beyond the intro
- →Handle hesitation, silence, and soft objections
- →A personalized approach to your specific market
- →Extended live call practice with direct coaching

- →Hours of live call practice with real-time coaching
- →Objection handling and closing techniques for your market

Your Coach
Dennis Czekalla
Entrepreneur, consultant, and international speaker who has built businesses from zero — in markets where nobody knew his name.
He founded the Isella Group, an international agency for strategic brand development and market entry, and built Berghaus into one of Germany's leading modular and tiny house manufacturers. Today, his companies operate across Germany, Poland, and beyond.
Dennis doesn't teach sales from a textbook. He teaches from experience — years of cold calls, client negotiations, cross-border deals, and building four companies across three countries. Every technique in this workshop is something he has used, tested, and refined in the real world.
As an Ironman finisher and triathlete, he brings the same discipline to the workshop room: structured, no shortcuts, results-driven.

Frequently Asked
Do I need sales experience?
No. DIAL IN starts from the very beginning. If you've never made a cold call — or if you've made hundreds but dread every single one — this is for you.
What language is the workshop in?
The workshop is conducted in English. Participants of any native language are welcome — during live call exercises, you can call leads in any language. Dennis provides best coaching support in English, German, and Polish. At least a good communication level in English is required to participate.
What should I bring?
A notebook or laptop, and at least 10 real leads you can call during the session. This is a practical workshop — you'll be making real calls, not watching slides.
What if I can't attend?
If you're unable to attend due to illness and notify us at least 48 hours in advance, you can postpone your participation to a future DIAL IN session at no extra cost. No refunds are issued.
Can I book for my team?
Yes. Custom workshops for teams and companies start at €2,499. Get in touch to discuss your needs.
Where exactly is the workshop?
Yolk Workspace & Community, Józefa Sarego 5, Kraków — right between the Main Square and Kazimierz. Easily reachable by tram (lines 1, 3, 52).
Is there a discount?
Discount codes are available on an exclusive basis. If you've received one from Dennis, you can enter it at checkout.
What makes this different from other sales trainings?
You won't sit through slides. You'll build your own script, test it on real calls during the workshop, and get direct feedback. Every participant makes real calls before they leave the room.
